Resize image to 20 KB
Application forms often cap photos and signatures at 20 KB. Open your image and get the sharpest version that fits, worked out automatically on your own device.
Runs entirely in your browser. "KB" here means 1,000 bytes; if a form counts 1,024, pick a target a few percent lower.
How to resize image to 20 KB
Crop first if needed
If the form wants a passport-style photo, crop to the face first with the resizer’s presets or your phone editor.
Compress under 20 KB
The tool tries the highest JPEG quality that fits, and only reduces pixel dimensions if it must.
Download and upload
The final size is shown before you download, so you know it will pass the form’s check.
Tips for very small file limits
At 20 KB, every pixel counts. A plain, evenly lit background compresses far better than a busy one, so photograph signatures on white paper and portraits against a plain wall.
Many forms also give pixel dimensions, for example 200 × 230px. Resize to those first, then compress; a small image reaches 20 KB at high quality.
Some portals count 1 KB as 1,024 bytes. If an upload is rejected at exactly 20 KB, set a custom target of 19.
Need more control? Open the full image resizer, compress image to 100 kb or change image dpi.
Questions people ask
How do I reduce a photo to 20 KB?
Open it here with the 20 KB target selected and press Compress. The tool searches for the highest quality under the limit and reduces dimensions only if needed.
Will my photo lose quality?
Some, because 20 KB is very small. The tool keeps as much as possible by using the highest quality that fits.
Is my photo uploaded?
No. Compression runs entirely in your browser.
