antoniolsampaio Posted February 13, 2015 Share Posted February 13, 2015 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 Link to comment Share on other sites More sharing options...
Staff MattP Posted February 13, 2015 Staff Share Posted February 13, 2015 Hi Antonio, This doesn't look very good - I'm absolutely sure we can find out what's going wrong here and fix it... Is there any chance you'd send us the original image you used for these tests as it obviously seems to show the problem nicely. Our email is support@seriflabs.com - we'll obviously delete the file after fixing the problem :) Thanks! Matt antoniolsampaio 1 Link to comment Share on other sites More sharing options...
antoniolsampaio Posted February 13, 2015 Author Share Posted February 13, 2015 Hi Matt The issue is also present in the other compression methods, including Lanczos 3. I'm going to send the original image over to you. Best regards, Antonio Link to comment Share on other sites More sharing options...

aitte Posted August 25, 2015 Share Posted August 25, 2015 Any news about this issue? I'm experiencing right now... Can anyone confirm this? Is Affinity's export JPG quality still bad compared to Photoshop? Link to comment Share on other sites More sharing options...
Markus Dierolf Posted August 26, 2015 Share Posted August 26, 2015 At present it seem so. AF has slightly bader quality und higher filesize compared to photoshop. It's ok for me for normal print jpgs, but for web I still use photoshop. But I'm sure the team will fix or improve this in the future. :) iMac (Retina 5K, 27-inch, 2017), i7 4.2, Radeon 580 Pro 8 GB, 40 GB DDR4-RAM, 1 TB Flash, macOS 10.14.6 Link to comment Share on other sites More sharing options...
Shmoo Posted August 26, 2015 Share Posted August 26, 2015 Can anyone confirm this? Is Affinity's export JPG quality still bad compared to Photoshop? I have seen similar problems, even Pixelmator creates better exports for some reason. For example this is a plain .jpg feel that wasn't touched by Affinity software before. Then.. I opened > cropped 3px from the bottom and exported it as a jpg with 100% quality. That should give about the same or less file size if I'm not mistaken. Look what I got back. 1.1mb is a lot bigger, the quality is about the same because I kept it nicely at 100% while exporting.

javaporter Posted January 7, 2016 Share Posted January 7, 2016 I'm running into the same issue. Moving back to Photoshop until I can figure it out. Has there been any movement on this since August? Link to comment Share on other sites More sharing options...
num3thod Posted February 3, 2016 Share Posted February 3, 2016 Also experiencing this issue. And it seems PNGs are of lesser quality too. Am using PhotoBulk for resampling (resizing) / compression until this is resolved in AF. Great software many other aspects though. Keep it up guys/gals.

Kris Posted February 3, 2016 Share Posted February 3, 2016 I have problems with jpg quality. Image straight from camera, basic edition (white balance, levels), resize (Lanczos separable), save (Lanczos separable). Look at edges of this picture: http://postimg.org/image/sbpy71q6n/ Edges with Bicubic resize are smooth. Link to comment Share on other sites More sharing options...
toyotadesigner Posted February 5, 2016 Share Posted February 5, 2016 Using these export settings I get phenomenal results without applying any unsharp masking: Original file from a digital camera with a size of 6030 x 4030 pixel @ 48bit @ 300ppi: Original file is a scanned large format negative with a size of 12.900 x 8.600 pixel @48bit @ 4.000ppi: Note that the software mentioned in the Exif is not AP - currently I use AP only for specific tasks. I just opened these files with AP and exported them to generate jpeg files The file size is identical to the jpeg files I am generating with another app. hobbyists discuss new camera features photographers discuss new software masters discuss light Link to comment Share on other sites More sharing options...

I just opened these files with AP and exported them to generate jpeg files The file size is identical to the jpeg files I am generating with another app. I'm using exactly the same settings for export images. But, I resize images before applying watermark. Resize with Lanczos is awesome with white edges, but with colored edges they are visible distortion.

toyotadesigner Posted February 5, 2016 Share Posted February 5, 2016 Maybe you can try to apply a watermark without resizing the image first, and then just export with these settings. If you resize first with these settings and then export again with the identical settings I could imagine that applying two times the Lanczos algorithm might lead to unpredictable results. Unfortunately there is no option to just save a resized image as a jpeg, png or tiff - you always have to apply a certain algorithm. hobbyists discuss new camera features photographers discuss new software masters discuss light Link to comment Share on other sites More sharing options...
toyotadesigner Posted February 5, 2016 Share Posted February 5, 2016 Export with resize from 6030 x 4030 pixel to 1500 x 1000 pixel, lots of colored edges in the chrome reflections, no distortion or artifacts hobbyists discuss new camera features photographers discuss new software masters discuss light Link to comment Share on other sites More sharing options...
toyotadesigner Posted February 5, 2016 Share Posted February 5, 2016 Another test with even more colors, critical shadow and highlight areas. Original size 6030 x 4030 pixel. Cropped to 2:1, converted color profile from ECI RGB to sRGB, resized to 1500 x 1000 pixel using Lanczos as mentioned above. Then exported with the same settings as above. Very fine details in the jpeg. hobbyists discuss new camera features photographers discuss new software masters discuss light Link to comment Share on other sites More sharing options...
Markus Dierolf Posted February 5, 2016 Share Posted February 5, 2016 This option gives very good results, with some certain problems you have to know. Unfortunally is the filesize much bigger than done the same manor in Photoshop. So good results are possible but still with bigger filesizes. iMac (Retina 5K, 27-inch, 2017), i7 4.2, Radeon 580 Pro 8 GB, 40 GB DDR4-RAM, 1 TB Flash, macOS 10.14.6 Link to comment Share on other sites More sharing options...
davidhq Posted February 5, 2017 Share Posted February 5, 2017 Replying to this thread 1 year later... I just bought Affinity Photo and also noticed very poor image quality for the same file size as Photoshop. Any official comment about this, will it be improved soon or do we accept it staying this way? globalmatt 1 Link to comment Share on other sites More sharing options...
jmac Posted February 6, 2017 Share Posted February 6, 2017 I don't understand why there has been no comment about this issue from a developer since Feb 2015. Perhaps it is in a different thread? Link to comment Share on other sites More sharing options...
globalmatt Posted January 11, 2018 Share Posted January 11, 2018 I also just purchased Affinity Photo and am really surprised at the poor JPEG export quality. Are the developers addressing this issue? Link to comment Share on other sites More sharing options...
pmi Posted January 12, 2018 Share Posted January 12, 2018 Yes, this is terrible! Affinity's export JPG quality still bad compared to Photoshop? After two years of AP and AD, I still need use Photoshop for export JPG. In addition, the preview is still missing, when you compress the image you can not view quickly the result ...
