ExactKB

Big photo. Small file. Compress a photo to fit a size limit — checked byte by byte, on your phone.

Pick a limit: 20 · 50 · 100 · 200 · 300 · 500 KB, or any number.
PASS means the real file is under the limit. If it can’t be done, you get an honest FAIL.
Send on WhatsApp as a Document so it isn’t compressed again.
Nothing is uploaded. Works offline. Camera and location metadata removed by default.
