Crop before you compress
Empty background costs bytes. Cropping tight on the subject leaves more of the size budget for the detail that matters.
Resize an image to 80 KB
80 KB suits detailed scans of certificates where small text must stay readable. Drop your photo in below — the target is already set to 80 KB, and everything runs inside this browser tab, so the image never leaves your device.
How to get a photo under 80 KB without it turning to mush
Match the required dimensions
Most forms cap both KB and pixels. Set the dimension preset here as well so a 80 KB file is not rejected for being the wrong shape.
Use JPG for photos
PNG stores photos far less efficiently. Choosing JPG output often reaches the target with visibly better quality.
Who asks for 80 KB?
80 KB suits certificate and mark-sheet scans, where small printed text must survive the upload intact.
Settings that actually reach 80 KB
Scan at 200–300 DPI, crop to the page edges, and target 80 KB with the long edge around 1200–1600 px. Sharp text at moderate quality reads better than soft text at high quality.
The mistake that gets uploads rejected
Photographing a certificate at an angle. Perspective distortion forces the compressor to encode blur, wasting bytes. Use the built-in document scanner to straighten the page first.
Questions about 80 KB uploads
- Can I extract the text afterwards?
- Yes — the image-to-text tool runs OCR locally on the same device, so a compressed scan can still become selectable text.
- Does compressing lose the DPI metadata?
- The pixel dimensions are what matter to every portal; DPI tags are advisory and are recalculated by whatever software opens the file.
