Why forms reject your photo
Most portals cap both file size and pixel dimensions. Matching one and missing the other still fails, so set both here before you upload.
Compress an image to an exact size
Upload forms rarely say "make it smaller" — they say "under 50 KB, 35×45mm". This tool hits the number exactly: quality is tuned first, resolution only if it has to be. No account, no watermark, no upload.
Quality before resolution
Shrinking pixels destroys detail permanently. We binary-search JPEG quality first and only downscale when the target genuinely cannot be met.
Nothing leaves the device
ID photos and signatures are sensitive. This page never sends the file anywhere — close the tab and it is gone.
