How the result works
Photo quality depends on more than pixel dimensions. This report combines resolution, estimated sharpness, tonal contrast, image format and file size. It helps identify whether softness comes from a small source, blur, flat contrast or repeated compression.
- Start with the largest available original
- Avoid judging quality from file size alone
- Keep an untouched copy before editing
Common questions
What makes a photo high quality?
A useful source normally has enough pixels for its intended size, visible edge detail, balanced contrast and limited compression damage.
Is a larger file always better?
No. File size depends on dimensions, format and compression. A large file may still be blurry.
Can I check an iPhone photo?
Yes. Choose a photo from Files or the photo picker and the report will run locally in your browser.
