I volunteer at a cat shelter and somehow ended up handling a lot of the photos we use for adoption sheets and PDFs.

The annoying part is compression. Some tools make the file smaller but the photos turn muddy, especially with black cats or low-light phone pics.

What I’ve tried so far:

• PDF Guru: I started using it for PDF forms, then noticed it also has image upscaling/compression stuff. Handy when I need to fix a few images and keep everything in one PDF workflow.
• Upscale.media: decent for quick image cleanup. Free limit is small, but enough for testing.
• Let’s Enhance: probably the strongest one for rough photos, but feels like overkill if I only need a couple of simple fixes.

Still testing. For anyone who works with image-heavy PDFs, what tools actually keep decent photo quality after compression? Especially for low-light pics.
