Newbie here. I've exported my artboard into JPEG, and I saw that there are lines on the right and lower borders on the document. It's not consistent with the upper and the left borders that has no visible border lines at all. What do I need to adjust or do to on/off those lines prior to export? Thanks a lot to whoever who will answer! ☺️ PS: It looks like the lines doesn't show on the preview below, but the lines are visible when I open it on my PC photo viewer
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. I have watched the tutorial for compressing a jpeg image for websites, and tried to follow the instructions. But the file, at 700x1000 pixels, is 863kb. That is huge for a website. I have tried reducing noise, I have the quality set to 50, I have progressive selected, embedded metadata unchecked. Not sure what I am missing. In photoshop, that file would have been no larger than 250k, so I know it should be smaller. Can someone explain what I am doing wrong? Thanks!
Hi, Let me start by saying that Affinity Photo is an amazing piece of software, nevertheless I stumbled upon two issues that I consider relevant: Image quality and file size of exported JPEGs. I was testing Affinity Photo's export feature and noticed that it produces more pixelated JPEGs when compared with the "Save for Web" feature in Photoshop. The file size is also larger (19 Kb in Photoshop vs 23 Kb in Affinity). These two JPEGs were exported with the same settings. Notice the pixelation on the second image (Affinity). Photoshop (quality 40 / Bilinear) - 19 Kb: Affinity Photo (quality 40 / Bilinear) - 23 Kb: I wonder if there's a workaround for this (both for quality and file size). Thanks in advance, Antonio
