How do I compress a photo

How can I compress the size of the photo after I download it?

The only way to compress a jpeg file is to use an editor that can change the quality level, i.e. jpeg compression, of the image file at the cost of image quality.
Compressing the jpeg file with the system, i.e. Control (right) - click on it and selecting Compress from the contextual menu does not reduce the file size.
If you have the photo in an iPhoto library it can be exported via the File ➙ Export ➙ File Export menu option where you can set the Quality level lower so that the file size is reduced.
The size menu in the screenshot is the image size, i.e. it reduces the number of pixels in the image. The JPEG Quality  menu just affects the file size.

  • How do I compress a photo album.

    Hello guys,
    This may seem trivial but, I have saved two photoalbums in PDF format (16 Mb and 19 Mb) and would like to send them via hotmail to my brother in Canada. Hotmail, like you probably know, has a 10 Mb attachement limit. Any ideas?

  • Compressing of photo files

    When uploading images from a camera into iphoto, how can I compress large photo files that take up too much space?
    Thank you for your help.

    Welcome to the Apple Discussions.
    If your photos are too large change the settings on your camera to take photos at a lower quality. But remember that you will be reducing the quality of the images.
    Other than that, you will need to edit the photos in a photo editor prior to importing to iPhoto.
    If disk space is an issue, you know that you can run an entire Library from an external disk?

  • Compress a photo before sending

    How do I compress a photo file before sending?
    Are there settings one can use to reduce the file to say 50 Mb or so?

    Hello and Welcome to Apple Discussions. 
    Photos taken on the iPhone 3GS are 2048 × 1536 and about 1MB. When you email them they are reduced to 800x600 which is about 100KB.
    You can't change these options AFAIK.

  • Using ms word '08,  how do i compress a 50 page document from 15o mb -- about 25 jspeg photos?

    i have a 50 page .doc paper done on a imac '09 using  word for mac '08.  the paper has about 25 photos  mostly  .jpeg. imbedded in the word document.  the net size is about 150 mb.  how do i compress it?   word vx had a compression  feature that seems to be missing in '08 version.     i just want to do a document wide compression,  not a photo by photo compress.

    to compress (zip) the file, right-click on the document icon and select Compress from the contextual menu that appears. This will likely not reduce the size substantially, as JPEG is already a compressed format.
    You'll get much better results by reducing photo resolutions from within the application.

  • How do you compress a Tiff photo image on a mac so that it can be sent in an email?

    How do you compress on a mac a Tiff photo file so that it can be sent in an email?

    I don't believe .tifs are a web compatible format. Two options:
    1. You either have to compress it, where it becomes a .sit  or .zip file that is emailable. Your receiver will need to be able to decompress the file.
    2. Change it to a .jpg or .png file which are emailable.
    Like Mr. Perkins says your ISP may limit the size of files that can be emailed.
    I don't see where web compatibility relates to this issue in any way.
    I'd be shocked if any computer whatever is unable to decompress a zip file.  However, as Mr. Perkins and I have confirmed via testing, the amount of compression can range from negligible to significant, depending on the original TIF file.
    As far as changing to JPG or PNG, I don't know if that helps the OP.  The question was specifically related to TIFs.  Personally, I still prefer the MobileMe or Dropbox solution.  The recipient receives exactly what the sender wishes to send and email is not clogged up in any manner.

  • How do I stop mail compressing my photos?

    How do I stop mail compressing my photos? I have set 'Actual Size' in Mail and still the photos are compressed to thumbnail size.
    I'm using Mavericks 10.9.2 on a 2011 iMac.

    The best way is to use the Contextual menu application PhotoTool CM to losslessly rotate the photos before importing into iPhoto. Or use Xee, a free image editor with lossless rotation capability.
    If your camera has the auto rotate feature turn it off and then follow the suggestion above before importing. That will rid iPhoto of the modified version rotated to the correct orientation.
    TIP: For insurance against the iPhoto database corruption that many users have experienced I recommend making a backup copy of the Library6.iPhoto (iPhoto.Library for iPhoto 5 and earlier) database file and keep it current. If problems crop up where iPhoto suddenly can't see any photos or thinks there are no photos in the library, replacing the working Library6.iPhoto file with the backup will often get the library back. By keeping it current I mean backup after each import and/or any serious editing or work on books, slideshows, calendars, cards, etc. That insures that if a problem pops up and you do need to replace the database file, you'll retain all those efforts. It doesn't take long to make the backup and it's good insurance.
    I've created an Automator workflow application (requires Tiger or later), iPhoto dB File Backup, that will copy the selected Library6.iPhoto file from your iPhoto Library folder to the Pictures folder, replacing any previous version of it. It's compatible with iPhoto 6 and 7 libraries and Tiger and Leopard. Just put the application in the Dock and click on it whenever you want to backup the dB file. iPhoto does not have to be closed to run the application, just idle. You can download it at Toad's Cellar. Be sure to read the Read Me pdf file.
    Note: There's now an Automator backup application for iPhoto 5 that will work with Tiger or Leopard.

  • How can I compress photos when emailing from iphoto? current photos are 7-8Mb each

    How can I compress photos when emailing from iPhoto?
    current photos are 7-8Mb each if I just attach them directly

    Aperture won't delete the photos from your iPhone. Most users have settled on using Image Capture ater importing into Aperture to delete the photos from the iPhone.

  • In iphoto, how do i save a photo after editing, in the same or higher file size, it's saves in a lower size

    in iphoto, how do i save a photo after editing, in the same or higher file size, it's saves in a lower size

    It's rather more complicated that this.
    iPhoto is a lossless editor. You don't lose any quality on your shot in iPhoto.
    The file size you see reported is the size of your iPhoto Preview: this is what gets used if you access the data via a media browser. It's a "good-enough-for-most-uses" version of the shot. Email it, upload to websites, use it in Presentation, Word processing file etc
    If you want to set the quality yourself then Export the photo using the File -> Export command.
    You can choose to export to Jpeg, Tiff or png. Tiff is lossless but the file sizes are up to 10 times larger. Jpeg allows you to choose different qualities: High, Medium or low. The difference is the amount of compression involved. High quality means very little compression. It's not unusual for photos exported at this setting to have a larger file size than the original.
    Which setting you choose depends on the use you intend. Further editing, printing then high is important. Sending to Facebook? Well low will do just fine there as they're going to trash the file anyway.
    But the key point: the file size only becomes an issue when you export.

    How can I copy a photo from iphoto to PReview to make it smaller for uploading to a site that requires a smaller image?

    I don't think you need Preview.
    Select the image and use File->export and you have full control over the size and compression.

    Just drop it into the message. It goes as an attachment. Or select the image, CTRL- or RIGHT-click and select Compress .... from the context menu. Then attach the archive.

  • How can I upload multiple photos without using an app?

    I'm a special education teacher, and I teach a photography lab that teaches students how to scan and edit photos. We use the school's set of Ipad2's in order to crop the photos since the majority of students I have don't have the hand eye coordination neccisary to crop using a desktop computer and mouse. The problem I'm running into, however, is that our IT department wont let me download any apps onto the iPads. I've asked on six seperate occasions in order for them to update the iPads to ios7 and to give teachers the permission to install apps-- the first request coming at the start of the school year-- and they havent responded to any of them, so I'm not holding my breath.
    Currently, I'm uploading all of the photos my students scan to my personal dropbox account, and the students access that and download each photo individually onto their ipads. Not the easiest thing for special education students to do, but its doable. I have not found an easy way to get the cropped photos off the ipads, however. Any ideas? I could attach each photo to an email, allthough thats more trouble than its worth most times. Dropbox will only allow me to upload one photo at a time, and keeps overwriting the photo I previously uploaded with the new one if I try to upload a second photo. Photo stream is the obvious answer, but icloud is disabled on all the ipads and only IT can turn it back on, something they've been unwiling to do

    I worked in IT on the university level for four years so it's really frustrating to see more safeguards in place in a public school district any university. If we're trying to teach these kids to be ready for real life and then block out and don't let them use half the technology they're going to encounter in real life, well I just don't get that. But that's another rant for another time.
    How I do it is I save all of the photos my students scan onto my external hard drive, then transfer them to my personal computer and upload them to dropbox using Dropbox for windows (or whatever the desktop application is called) . I then have my students go to dropbox.com on the iPad, login as me, and go through each photo, saving each to the iPad as they go.
    I should have said upfront that when I try to connect the iPad to my personal computer it charges the iPad but won't recognize under my computer or show up in iTunes, so I am unable to see any of the data on it. I'm pretty sure it's not the 30 pin connector that's malfunctioning because I've tried with two of them. I can only check if it registers with iTunes on my personal computer because I can't download iTunes on school computers since I don't have administrator privileges

  • I restared my Iphone 4s and now my photos are just grey with JPG in it. How do i get my photos back?

    I restared my Iphone 4s and now my photo's are gone. They are just grey with JPG in it.
    How do i get my photo's back? And why are they grey?
    Any help would be nice.
    Thank you.

    Restarting your phone doesn't cause it to grey out.
    Were you restoring from an icloud backup?  IF so, it does take awhile for pictures to download.
