Testign if 4chan still reencodes images.First is a MS Paint created PNG file.
>>108548197Size and checksum is the same in both uloaded and downloaded image. Now trying JPG file created in MS paint.
why would 4chan reencode?
>>108548216Size is slightly smaller and hash is different. But it's so small, it's probably removed metadata and the image is not reencoded. Archives usually have the non reencoded images, and the file downloaded directly from 4chan is the same as the one downloaded from the archive.
>>108548251removal of EXIF data plus optimizations by Cloudflarehownew.ru ?
>>108548197>>108548216>>108548256Conclusion: 4chan probably finally stopped reencoding all images. And the image you downlad will probably be the same that was uploades (minus metadata).
Now trying to bloat the filesize as much as possible.
>>108548314Downloaded file has the same hash as the file uploaded. It wasn't "optimized" in any way.
4chan only ever reencoded images for delivery to phoneposters.
>>108548296you haven't tried gif
Nice yellow slut
>>108548375Trying MS Paint created GIF.
>>108548388GIF uploaded and GIF downloaded have the same checksum
>>108548197try putting a bunch of shit like tEXt chunks.
>>108548197Now try webp
>>108548197>>108548216>>108548314>>108548388GATA SESSOOOOO!
>>108548197That's a man
>>108548369it happened on desktop too, almost all images had some cloudflare compression. could be bypassed but now its finally over
