Will resizing to 20KB ruin my photo quality?

The tool reduces quality gradually and stops as soon as the target size is reached, so quality loss is minimal. For documents, PAN cards and passport photos at 20KB the result stays perfectly readable.

Is my photo uploaded to a server?

No. Everything happens locally in your browser using the Canvas API. Your photo never leaves your device.

About this free image resizer

Government portals, job applications and exam forms across India and Pakistan ask for photos under strict limits — 20KB for signatures, 50KB for passport photos, 100KB for documents. This tool hits those exact numbers. Upload a JPG, PNG or WebP, choose a preset, and the resizer binary-searches the JPEG quality setting (and shrinks dimensions only as a last resort) until the output lands at or just under your target. Because it stops the moment the size fits, visual quality stays as high as possible — text on PAN cards and documents remains crisp and readable. Everything is computed locally with the Canvas API: no server, no queue, no account, no watermark. It works offline once the page is loaded, handles photos from any phone camera, and never stores or transmits your image.

Frequently asked questions

How do I resize an image to 20KB?

Upload your photo, select the 20KB preset and click Resize Image. The tool tunes quality and dimensions until the file is 20KB or slightly under, then gives you the download.

Will my photo look bad at 20KB?

Quality is reduced only as much as needed to hit the size. For document photos, ID cards and signatures the result stays sharp and readable. Very detailed photos may show mild softness — that's the trade-off of any KB limiter.

Can I resize a PNG photo?

Yes. PNG, JPG and WebP are accepted; output is JPEG (best for photos) unless your image has transparency worth keeping, in which case PNG is used.

Is there a file size limit?

No upload limit — files never leave your device. Very large phone photos just need a moment to process in your browser.
