Compress an image to 300 KB Get a photo, ID scan or document picture under 300 KB for exam, visa, bank and government upload forms, using JPG quality search and resizing only when needed. Your image stays on your device.
FAQ How is 300 KB measured? The default ceiling is 300 × 1024 bytes; set 292 KB if your form counts 300 KB as 300,000 bytes.
Will text in a scan stay readable? Usually yes. Quality is lowered before dimensions, so a typical A4 scan stays legible under 300 KB.
Is my file uploaded? No. Compression runs in your browser and the image never leaves your device.
