Jpeg vs. pdf vs. png?

what are the pro's and con's of the different formats?
would pdf's make for a smaller size download? do all support interactivity? video? audio? hyperlinks?
thanks for any help!

Oh yes, i need this too!

Re: jpeg vs. pdf vs. png?

I don't know enough to understand the technical aspects. Quality is more my concern than speed. I used Acrobat and Foxit but as soon as i hit a print button, the quality on my screen went to hell. I don't have photo shop. How do I solve the problem?

What problem? Please describe in more detail. Quality of what? In what app? On what system? In what way are you comparing the three? Remember, we can't look over your shoulder.

Need to convert 'My thoughts' app work into either .jpeg or .pdf

Hi,
I need to convert a piece of work, designed through 'My Thoughts' app into either a .jpeg or .pdf format in order to send to Staples to have it printed off - have clicked on save but these two options are not included ... any ideas?
Thanks in Advance

I don't have "My Thoughts" but you should be able to command-P and then at the bottom of the print screen you'll see PDF and you can just save as PDF from there.
All of my printers (including Staples) require PDF documents these days.

Is it possible to have PDF and PNG versions of 'same' folio

Is it possible when copying over the articles to have one folio as PDF and another as PNG?
Tried doing this by setting up an alternative folio as PNG and copying across the articles that were created for the original PDF folio, but they still appear to be PDF when loaded into the new folio and previewed on tablet, even though it has been set to PNG.
Do they only get converted to PNG when published? shouldn't one be seeing thumbnails in the DPS Folio Producer: Editor browser window. Trying to preserve the meta data tags between folios, or do I have to re-export these files and re-input the tags and attributes manually.
I see there is a way of copying articles between folios at an admin level, would this result in a correct transposition of PDF to PNG?

We use the K4 publishing system, and haven't started using their plugin yet, as we are still 'kicking the tires'. That said PDF and Android don't play together so well, hence looking at a PNG version without having to re-enter all the metadata again, which is what happens with the method you describe above.
The trouble is that the meta data is not part of the Indesign document so we have to re-enter it all plus there is the open/checkout/checkin/close of all documents from K4 which is a royal PIA, so uploading the same indesign documents isn't really helping. If the sidecar file worked 'properly' then perhaps that might be a solution, hear its not quite there though?
So, copying the article across to a new folio looked like it might work but not sure why when it asks when setting up the folio, whether you want PDF or PNG specs those do not stay set or why they are ignored on copying to the new supposed PNG rendition.
Would the K4 plugin solve this? would it work for all formats if we are building an Ipad and iPhone and Android version of a folio from the same document sourced in K4.

Error message when saving a PDF to PNG: Error attempting to write file.

I get an error message when saving a PDF to PNG. JPG and TIFF works, but no PNG.
Disk space is sufficient! 100GB of 250
A few weeks ago it was no problem to save as PNG. But now! (Perhaps from last update?)

I have this issue too, but my colleagues do not have this issue(we have same Acrobat Pro 11.0.09). I am sure this issue happens only you updated to 11.0.09, because when you use Windows Restore back to 11.0.08, no issues.

I have used Image Capture to scan images/documents and then saved them as either PDFs or PNG files. For some reason, just this past week Image Capture will no longer save the file. It scans, and the Scan Results window pops up, but it won't save file.

I have used Image Capture to scan images/documents and then saved them as either PDFs or PNG files. For some reason, just this past week, Image Capture will no longer save the file. It scans, and the Scan Results window pops up, but it won't save file.
The file name has no special character in it, just letters and no spaces.
I have done this in the past and it has worked, but now it will not.
I have not upgraded any software, that I am aware of.
After scanning, the Image Capture pops up the Scan Results with the file name in the window, but neither the Scan Results nor the Image Capture window responds to inputs. The Image Capture window is frozen, with only the "Overview" and "Cancel" buttons active (but non-responsive).
Is this a software issue or a scanner hardware issue? I am using a HP Photosmart C6200 series printer/scanner on a network using a Time Capsule airport.
Thanks.

I had the same problem.
Got a 90% fix. Apparently the Mavericks preferences won't work with Yosemite, so I just deleted the Image Capture preferences.
Unfortunately, the "Scan to" folder seems to be permanently set to the Pictures folder.
1. Quit Image Capture
2. Go to Finder > Go > Home, which opens up your home folder (named after your user name)
3. Open Library > Preferences > com.apple.ImageCapture.plist - Drag this file to the Trash
4. Start "Image Capture", click "Details" and change all your settings as you prefer
5. Quit and restart "Image Capture". Notice it remembers all your settings except "Scan to" folder. It insists on saving to "Pictures".
That's as far as I was successful. I tried changing the "Scan to" folder to "Desktop", but on launch, Image Capture always sets it back to "Pictures".
This is what I tried:
6. Download and install "Pref Setter" from http://www.nightproductions.net/prefsetter.html
7. Quit "Image Capture". Right-click on "com.apple.ImageCapture.plist" and open with Pref Setter.
8. Search for "Pictures", which finds "~/Pictures" (the tilde character at the start means your home directory).
9. Double-click on "~/Pictures" and change it to the folder you prefer. I like "~/Desktop"
10. Choose File > Save then Quit from Pref Setter. Note that re-opening the plist file still shows "~/Desktop"
11. Start up "Image Capture" -- on startup, "Image Capture" sets "Scan to" folder to "Pictures"
I consider this a bug.

Just upgraded to Mavericks. Now I cannot access scans from my hp scanner. After it complete the scans and I try to save as tiff, jpeg or pdf I get a either a grey blur or a message that says cannot save because the file cannot be written to.

Just upgraded to Mavericks. Now I cannot access scans from my hp scanner.

I did not have any problems before the upgrade. I would greatly appreciate any light shed on this.

Go to the HP site and look for drivers for your scanner. It apparently needs an updated driver to work with Mavericks.

I need to convert hundreds of TRANSPARENT PDFs into PNG or TIFF

I need to convert hundreds of TRANSPARENT PDFs into PNG or TIFF.
That's not possible with Acrobat. It’s possible to convert hundreds of PDFs into PNG or TIFF using batch processing. But transparency is LOST!
Photoshop is the only software I know of which is able to keep transparency when converting from PDF to PNG.
But now I have problems to get batch processing running.
I made an Action with “Open file”, “Save as PSD” and “Export to PNG”.
Using this Action in batch-process-files with source as a folder with many PDFs and target as a different folder results in many opened PDFs within Photoshop. Nothing else happens:-(.
Any ideas?
Thanks
Norbert

Great:)
It worked at once.
Thank you so much for this link.

Acrobat Crashes when converting PDF to .png

I've been having a problem for a while now. I'm using Adobe Acrobat 8.1 Pro and when I try to convert PDF to .png, acrobat crashes. It doesnt let me do it and I´ve been trying with different documents. Anyone with the same problem? It would help me a lot if you have a solution. Thanks

Hey,
You might try reducing the size of the PDF file and then convert to .png.
Also, please check for updates for Acrobat 8 and try repairing.
Let me know if this helps.

Anubha

Jpeg and PDF clipping paths not showing up in Keynote

I am using Keynote '08 and my boss is using an earlier version. He wants to place a jpeg or pdf in his file and see the clipping path. He has pdfs on his machine that open in his keynote document with the clipping path intact, you don't see the white background of the image. When he places the jpegs and pdfs I have sent him, with clipping paths I created, in the same keynote document, mine show up with the white backgrounds.
Help!

The previous designer here saved jpegs and pdfs with clipping paths that apparantly he can open. I give him a jpeg with a clipping path (created by someone else) as well as save it as a PDF with clipping path and he cannot see the clipping path. He specifically wants to use jpegs or pdfs because that is what he has been using and that is what has been working for him until I sent him jpegs and pdfs that aren't working. So far it is just this one photo as a jpeg and saved as a pdf. I cannot find any difference between these two and the ones he is able to see clipping paths on.

I created a photo book in Photoshop elements 11 that contains png files with the invisible backgrounds. When I export the book to a jpg or a pdf, the png files appear with white backgrounds.

jpg and pdf formats don't support transparency. You need to use a format such as tif, png or psd that does.

Acrobat cannot export scanned PDF to PNG

Hi,
When I tried to export a scanned PDF (download link: example.pdf - 坚果云 - 云存储|云盘|网盘|同步|备份|无限空间|免费网络硬盘) to PNG image, I got an error message as below:
The PDF can be exported to PNG on my firend's laptop using acrobat.
Can anybody help? What additional infomatin should i provide?
Thanks and sorry for my English.

Thanks for replying.
Yes I checked disk space. More than 200 GB of free space. The example PDF file contains only one page.

How to stop Preview from changing resolution when converting JPEGs into PDF

I am combining several JPEGs of identical resolution into a PDF using Preview, using either the sidebar or Automator action (http://discussions.apple.com/thread.jspa?messageID=11893607). For some reason, Preview changes the resolution of the PDF so viewing it at actual size (100% zoom) is bigger and pixellated. Example: a 960x600 JPEG becomes approx 1355x845. I figured it had something to do with dpi and indeed if I do the calculation and open up each JPEG in Photoshop and resize (without resampling, i.e. without changing pixels) to 101.5, the resulting PDF is pretty close to what it should be. (Calculation = 1355/960 * 72dpi.) But the slight resize and recompression lowers quality, plus it's a huge pain to go through all of that for every image.
This issue is the same for simple saving a single image, the combining and use of Automator script has no impact.
My question, in summary: how do I get Preview to save a JPEG as a PDF without changing its resolution?

I have the same problem. I have a bunch of scanned documents (jpeg), and have been trying to make them a multi page document, instead of 20+ images.
Using the Automator "New PDF from Images" preview action v1.0, supplied by Apple with Snow Leopard, and I am able to convert the images to a PDF.
Using these images, the first page being 1032 x 1600 pixels, and telling the automator action to +size each page to fit image+, I convert them into a PDF.
Converted PDF is viewable here.
The original JPG is clearly higher resolution than the PDF, and the PDF loses the crispness of the original scan. Even using "+size each page to fit image+" does not make the page the original image size.
What's happening here, and does anyone know a better way to convert Jpegs to PDF on the Mac - and keep the image resolution? I don't care about files sizes here, but keeping resolution and maintaining quality.
