In making a book of photographs to be printed by a print-on-demand company, I found I'd exceeded their 300 MB per PDF limit even before I had all image files placed in the Publisher document. The idea of further JPEG compression was not appealing but I decided (holding my nose the entire time) to try compression settings during export to PDF. The results surprised me. No compression: 388.5 MB No compression (2nd time around): 363.4 MB (why the difference?) Compression setting 100: 211 MB Compression setting 99: 182.7 MB Compression setting 97: 139 MB Compression setting 95: 114 MB Compression setting 90: 83 MB I take it this means that the max quality setting (100) still involves re-compression of the images. All along I'd thought 100 means: no compression. Apparently not. So if output file sizes are plaguing you, perhaps the slight JPEG compression will be helpful. Before starting the tests I ran the original JPEGs through the compression program JPEG-Mini. It made a whopping difference in the files' sizes and without noticeable loss of quality. But using the JPEGs compressed with JPEG-Mini as source files within the Publisher document doesn't seem to have provided a lot of savings during export to PDF. Perhaps JPEG-Mini's major advantage is a "web thing" and not a "print thing".
Hi there I'm a Photoshop user who's crossed over. I resize images for web and on Photoshop would resize images to the physical dimensions I needed (1300px long edge, 72 dpi, 'save for web'...) I resize images in the same fashion with Affinity, only instead of saving to web I save at medium quality jpeg (45%) Nonetheless, the files i used to save on Photoshop at about 350-400K now come out at around 800K. Am I missing something? This is a terribly large size for web use, but I don't want to reduce the quality to less than 45% as this will impact the reader experience. Thanks Jade k
I have a question on file sizes. Let's start with an observation; yesterday I worked on a fairly large drawing and did a "save as" so it would have a new revision, 428.5KB. Today I copied the file with the name changed opened the file in MAS and just hit cmd S. The file now is 726.5KB. I exited AD then reopen the 726.5KB file, did a "save as" to another name, now it's 428.4KB. I hit cmd S and it's back to 726.5KB. Did another "save as" to another name and that file is 428.4KB. So the question is what is up with file sizes? Why does a "save as" make a file 41% smaller than a "save"?
