Reducing image file size for web use without pixelation

Can anyone help me figure out how to best reduce images for fast web loading (in slideshows in Muse). I have done the save for web in PS and they are super pixelated now. The only versions that do not lose quality are the original size and they are huge files. Any help is appreciated.
Also can anyone tell me how big each image should be, what is considered a too big size (kb) for web images? Thanks Hillary

The settings I used were in the save for web panel and I saved the image as "medium" and the quality was 30, optimized was checked and it was scaled down to 16kb instead of 700kb. Is there a guideline as to how large in kb an image should be for good loading, it seems like with faster internet speeds we can go a bit larger for asset size. Is it OK to have an image as 65 kb if it is quite large (8 inched wide)?
I think I solved the problem. I just went in and saved the images as larger quality. I hope it does not slow things down too much. Any advice would help.

Reduce file size for web use

Hello,
I created a website some months ago and I realize now the images are far too large and it takes a second for them to load. So I opened them in photoshop and changed the PPI to around 50, but the file size didn't shrink. I tried 10, and still nothing. I tried Save For Web and the file size got larger. Any ideas on how to keep the image quality (for web) but reduce the file size for easy page loading? Thank you.

Don't worry over the ppi value. That's arbitrary.
You can reduce the pixel count, by resampling. That will make an image smaller in a hurry. To do this, Image - Image Size, check the [ ] Resample Image checkbox, and change the pixel counts. I always set my Photoshop prefs so that I see the Image Size in pixels by default. If yours isn't reading in pixels by default, change the units so that it is.
However, you may need to have your images be a certain size, in pixels, and so resampling isn't an option. In that case, when you do File - Save As - JPEG (or use Save for Web & Devices), adjust the Quality value to get the image to the size you need.
Hope this helps!

Changing file size for web use - multiple images

My most recent iPhoto event consists of 45 pictures, most of which are 1 MB or larger. I want to scale them down a bit for web use.
I do understand how the export command works. If I want to change all 45 pictures at once (select all), where should I export them to, and then what is the procedure to get them back into iPhoto? I would really like them to all show up as a new event in iPhoto (same pictures as the original event, only smaller file sizes).
Am I overlooking some easy way to do this?

No you’re not overlooking an easy way to do it.
Export them to a Folder on the desktop and then import them.
However, why are you keeping these web versions? The more efficient use of disk space would be to upload them then trash them. If you need other versions in the future you can re-do them. Not a lot to be gained by holding on to them, is there?

How to reduce image file size in spreadsheet

I have created a spreadsheet that contains cells with small amounts of text, and images that I brought in from the Media Browser from iPhoto. This has caused the file size to become HUGE, on the order of 234 MB. Saving it as a pdf only reduces it to 220 MB.
I have tried the Format>Image>Reduce Image File Size, as well as File>Reduce File Size, but in both cases, those options are grayed out.
What am I doing wrong? All I really want is thumbnail versions of my image files.
I don't understand what the Reduce Image File Size command would be used for, if it doesn't work for this?

When you insert a picture in a cell, it's used as a background.
To do that, the app keep it in a size allowing it to accomodate the larger cell size permitted.
If you want to get small images matching the cell size which you use, you must reduce the picture by yourself before inserting it. For instance, cells are often 72 * 16 pixels ones so you may reduce your pictures so that thir width become 72 pixels.
Of course, if the user enlarge the cell, the picture will become highly pixelated.
Look at this example.
In B4 is the original : 202 x 177 pixels
In C3 is the reduced one : 72 x 63
in B2 is the reduced one in a 202 x 177 pixels cell. It's awfully pixelized
We must arbitrate between size and quality.

What is image dpi after "Reduce Image File Size"

Does anyone know the resulting image dpi after using the "Reduce Image File Size" command in pages? My mother is trying to prepare some things for pre-press, and can't send her document to the printing press, because the pages docs are friggin huge! I'm trying to give her the easiest option for resizing all of the many images in the document, but don't know if this is a viable option if the end product needs to be printed. I need the output to be at least 300dpi.

As fruhulda wrote, asking Pages to apply changes to the pictures isn't the good path.
In fact, it's a perfect way to get a fat file.
My practice is :
Prepare the document in Pages to define the wanted size of every embedded pictures.
Edit the picture files in a tool dedicated to this task so that the resulting files will be 300 dpis ones for the wanted sizes.
Then, replace the original pictures by the definitive ones.
In most cases, the file will be lighter than the original one and you will have the 300 dpis resolution (except if you apply shadows but it's an other story).

Using Pages with iOS. How do I reduce image file size when I create a document with embedded images?

Hi,
I have created an annual family news letter in Pages on my iPad which incorporates pictures of events, holidays, occasions etc etc. I've then gone to covert it to pdf with the intention of sharing it via email but get a warning message about the resulting file size (in this case 16Mb).
Is there any way of reducing the file size - which is obviously being driven by the images? The pics are being pulled in from the iPad photo library.
Thanks Mike

(1) you are asking about Pages for iOS in a forum dedicated to Pages for OSX.
Most of us aren't using Pages for iOS so it would be more efficient to ask in the forum dedicated to iWork for iOS (at this time this discussion area isn't divided in three areas).
https://discussions.apple.com/community/app_store/iwork_for_ios
(2) As you understood why your file is huge, the answer is simple : reduce the size of your picture files before inserting them in Pages documents.
Drop the unneeded areas, reduce the resolution in tools dedicated to image processing before inserting them.

Reducing MP4 File Size for online upload

I have a short HD video almost 1 GB in size (impossible to upload online). Is there an easy way to reduce the file size using IMovie or another program that I don't have to go out and buy?

I don't think you'll have too much success with this. Mpegs are already compressed files, so there's no real benefit to trying for further reduction. In some cases using compression software will make the resulting file larger than the original.
There are utilities that can be used to slice up a file into smaller parts that can then be reassembled. For example, Movie Cutter, SplitFuse, Split&Concat, MacAppStuff Pieces are a few. Look for them at VersionTracker or MacUpdate. Stuffit Deluxe is a commercial product that includes the ability to split and join multiple pieces of a file archive and has the benefit of being available on both Macs and PCs.
You can then split a large file into several smaller files to send via email or to upload to file server sites. Of course the recipient will need a compatible utility to join the pieces.

Reducing AI file sizes for PDF distribution

Greetings all,
Using CS2 Illustrator, I have a file that is approximately 14.5M large. It's completely black and white, with a b/w photo. I was thinking that when I saved it as a pdf file, the size of the pdf document would be considerably smaller so people could send it by email. It came down to 1.9, but I'd like to get it smaller than that. I'm guessing I have to reduce the size of the embedded photo?
I also have a version of the file with a color photo. It's AI size is 34.1M, it's converted pdf file size is 32.5. I'm desparate for a method that will get these two documents down below 1M size so that members of my Barbershop Chorus can send the pdf files out announcing our upcoming show.
Any help GREATLY appreciated.
Thanks,
Bond

When you save the PDF, Illustrator will downsample images according to the settings you chose. Downsampling the source images won't help for file size. Usually the biggest source of bloat is leaving "Preserve Illustrator Editing Capabilities" on. This adds the entire Illustrator file to the PDF.
I suggest you start with Smallest File Size and adjust the downsample options under Compression. Reduce image resolution if sizes are still too big or increase resolution or image quality if sizes can be increased and quality is unacceptable.

Jpeg Image file size for a Downloadable Product

I'm creating a site in BC for the client to sell digital download copies of their original photographs. The purpose of the product for the consumer would be to use the low res download as a screen save or for viewing in a gallery on a desktop, tablet or smartphone device. BC accommodates such products but I haven't a clue as to what size to upload the image files in the BC Product Details page.
Does anyone have any relevant information to share?

If the client intends on selling digital copies of the images, then I would make sure to make the previews small. Like 600 x 800 small. If it gets too big people aren't going to be inclined to pay for bigger.
I usually upload my photos in 1040 or 1280 on social media. But 1280 looks pretty good on most laptops. That'll change as screens get denser, but as of now I would think if I was trying to sell images and had previews at 1280 a lot of people would just take the 1280 and run.

File sizes for web ads

Hi guys
I'm trying to figure out how large the final file size of my ad is so I can ensure it's under 40k. I'm sure there's an easy way to find out I just dont know it yet. Anyone able to help?
Thanks!

Hi Rossco,
If you are publishing an oam, on Mac you can select the oam, then use "option+click", then select "get info" for total file size.
If you're doing a normal web publish (File/Publish Settings/Web/Publish), when you actually publish the project, Edge will create a "publish" directory with all your files in it. Select that "publish" directory, and use "option+click", then select "get info". By the way- to save physical file size on disc, make sure the "Frameworks via CDN" tab is checked. This will load the various js libraries from the CDN, rather than storing them locally with your project.

Optimum QT file size for web

I'm new to iMovie 08 and iWeb, publishing to a folder not my iDisk. Is it better to use the Share feature in iMovie, or to export my video files to QT for upload to my site ? If to QT, what's the optimum size for loading and viewing?
Thanks,
Bob

Is it better to use the Share feature in iMovie, or to export my video files to QT for upload to my site ?
This normally depends on your target file/workflow needs. The "Medium" share option s a good, general purpose setting. It is compatible with QT Pro, iTunes, Front Row, iPhone, iPod, TV, gallery, and iWeb use via high-speed connection. If you want lower data rates, use a phone modem, mono audio, need CD/DVD ROM playback compatibility, or have other special issues, then other "share" pre-sets or export options with user selectable options would be better a better choice.
If to QT, what's the optimum size for loading and viewing?
Once again, the is usually a compromise between use requirements, work flow, and the contents itself. As indicated above, a 640 width with appropriate height aspect display is quite common for most uses. I tend to use this for most content that combines action and drama. On the other hand, for things like video tutorials, I would be more likely to use something on the order of a 960x540 at 60-70% of the data rate used for "movie" files. Frankly, ther is an entire range of settings and compromises that can be made between display size, data rates, and content quality which the user normally has to evaluate in order to judge what best for him or her in any particular situation.

I need to change my image file size but keep the same pixels. Possible?

I'm trying to upload an image to a mobile ad platform (Adfonic) with the following requirements: Image dimensions 216 x 36 pixels; max file size 3.0 kb; file formats supported GIF, JPG, PNG. I figured out how to change the pixel size but now my file is too big. I have Photoshop CS4 Extended & Vista.
I changed the file resolution but then the pixel size changes. What can I do?
Thanks!

Save-As, JPEG offers you a quality slider. You trade quality for size. This still wouldn't give you what you needed?
You could try JPEG 2000, but beware, it's not as compatible with as many things, and it can look kind of weird, but boy does it compress...

Reducing image file size ???

i dont this accidentally and dont know how to do it again, i think it invloves iphoto/preview and exporting or saving as.....
basically i have a batch of digi cam pics averaging at 3mb and want to reduce to like 150kb each like ive managed to do unintentionally before
dont want to export in iphoto or create workflow where you have to specify pixel size ratios because i dont want them to be limited size-wise, just want to do it the way i did before, mac done most of the work
if anyone knows what i mean or has an alternative solution, it would be much appreciated, thanks

But you don't know how you did that and there's no way anyone else can know either. I suspect that you've accessed the files in the DATA folder of the iPhoto Library Folder - these are the thumbnails that iPhoto creates and uses for display.
It is strongly advised that you do not move, change or in anyway alter things in the iPhoto Library Folder as this can cause the application to fail and even lead to data loss

Can I reduce video file size on iPad?

Is there an iOS app - iMovie for instance - that will allow me to reduce video file size on my iPad, without having to use a computer?

There are various Apps in the App Store that will compress a video file, try search on Video Slimmer or Video Compression. Another option is to use a different App for recording the video in the first place; I use MoviePro quite extensively, it allows 5 different presets for resolution, bit rate etc. for recording video.

Reducing song file size AFTER importing

I now realize that I should have used the iTunes preferences to set the import file type and the quality setting BEFORE importing songs. However, I now have over 170 songs in my iTunes library, and I would like to be able to reduce the file sizes for those songs. I will change the iTunes settings before importing any more songs, but I would like to be able to reduce the sizes of those files that I have already imported. Some of them are as large as 6 MB, while most of them are around 3 MB. Both are too big. Is there any way to take care of this problem? I am particularly concerned about those songs that I imported from the iTunes store after paying for them. Songs that I imported from my CDs can be done over, but I don't want lose the money that I have invested on those songs that I bought from iTunes.

Your answer reverses the usual order: it starts out with the bad news but then finishes with the good news...I think. I guess you're saying that nothing can be done with the songs I have purchased from iTunes. With them, I'm stuck with 3 MB for the usual 3-minute song. Well, so much for iTunes, then. I'll certainly never buy any more songs from them. That IS bad news. On the other hand, I think you're saying that I CAN convert songs I obtain from my CDs to smaller bundles. I used to do that quite routinely when I was in OS 9, but I'm not sure of how to do it now that I'm using OS 10.3.9. I hope it's not much more difficult, but I'll just have to see. Anyway, thanks for the information. Now I have to study OS 10 and the latest version of iTunes.
