Hello,

If i Export a Picture with 100% Quality as a jpg is the Quality i Copy on my Smartphone pixelatet (sorry for my English...hope u understand what i mean).

For a Test i Export the File as a Psd file and export the Picture in Photoshop under "save for Internet" as a jpg and copy this jpg on my Smartphone and this Picture has the good Quality that i need.

Looking for Help (maybe my bad, iam new at the Program Affinity Photo)

Thank u.

iput 2 pictures in the upload, one file is Affinity Photo and one is Photoshop.

The Photoshop has less mb than the Affinity file but is better on my Smartphone...

On the Computerscreen the 2 Pictures looking good, only after copy on Smartphone the Quality of the Affinity Picture is bad.

Thank u

I have uploadet a Zip file with the 2 Pictures, maybe anyone can Help.

I have tested now with 3 Pictures and by all Pictures its the same Result.

Maybe its the Smartphone? But no Problems by the Photoshop pictures....

I would try to reduce the quality in APhoto to reduce the file size.

Images is exactly same:

Hello thank u for your time,

At the Desktop on PC the Pictures look same but if i copy the Pictures on my Smartphone the Quality of the Affinity file is not good.

Have u try the Pictures of the Zip file? On pc or Smartphone?

How do you "copy" ? Since your Affinity .jpg has a larger file size maybe its forced to become reduced in the transfer process by an involved app?

What if you copy it from your smartphone back to your PC and then compare the images + their metadata?

Try smaller file size - half resolution, quarter quality (75%).

I can't unpack the .7z file. My macOS app appears to compress it once more (as ".7z.cpgz")

Obviously a matter how your phone, handling the two compressed files differently when opening / displaying them. As @Pšenda noted, they have different file sizes (aside the fact that Affinity jpg compression is not identically to the one by Photoshop). So you could try to export both with same file size result for instance, and/or check possible differences with a separate tool like the "exif tool" to compare compression details like encoding and sampling.
