What is this file, really?

Find out what a file actually is, not what its extension claims.

Name a file size and this searches for the best quality that fits under it.

WhatsApp stickers, Instagram reels, YouTube thumbnails and more.

Point at a folder and the converted files are written back beside the originals.

Turn IMG_4471.HEIC into 2024-06-12_143022_001.jpg using the capture date stored inside the photo.

Finds the same picture saved at different sizes and formats, which a checksum never will.

Draw a box over a face, an address or an account number and the pixels underneath are replaced, not hidden.

Strip the location, crop it square and shrink it in one pass over a whole folder, instead of three trips through the site.

Checks the three things that catch people out: where the file says it was taken, what is hidden in its tags, and what is legible in the picture.

Reads a screenshot and points at the API keys, tokens, card numbers and addresses in it, then covers the ones you pick.

Scores how alike two versions of a picture are and shows a map of where they differ, amplified enough to see.

Reads a folder on your own machine and reports the biggest files, the formats wasting room, and roughly how much converting would give back.

Convert a file and watch the browser count what left your device.
