Compress Image to 20KB

The tool below is already set to Max file size: 19 KB, so every photo you add comes out under 20KB — the size most often asked for by exam signatures, SSC and bank-exam uploads, and government forms with very tight limits. Add one photo or a batch, tap Process all, and download.

It finds the highest quality that still fits under the limit, and only reduces the pixel dimensions if quality alone can't get there. At 20KB a full-size phone photo almost always needs smaller dimensions too. Turn on Resize → Exact (for example 400 px wide) alongside the target, or the tool will shrink it automatically when quality alone can't get there. Everything runs in your browser; your photos are never uploaded.

Nothing here yet — add photos above to get started.

Only helps if your background is already one plain color (e.g. a wall) — this is color-distance math, not real subject cutout, so it won't do anything useful against busy or textured backgrounds.

How to compress an image to 20KB

  1. Tap the box above (or drag and drop) to add a photo — JPG, PNG, HEIC or WebP all work.
  2. Leave Max file size at 19 KB, and JPEG as the output format, which gives the smallest files for photos.
  3. If the form also gives exact pixel dimensions, set them under Resize → Exact.
  4. Tap Process all and download — the size shown under each photo is the final file size, under 20KB.

Frequently asked questions

How do I reduce a photo to exactly 20KB?

Add it above and tap Process all — the target is preset to 19 KB. The tool lands as close under the limit as it can at the best possible quality; hitting an exact byte count isn't needed, since upload forms only check the maximum.

Why is the target 19 KB and not 20 KB?

Some sites count 1KB as 1,000 bytes and others as 1,024. 19 KB (19,456 bytes) passes under either reading of 20KB. You can change the number in the settings panel if you know exactly how your site counts.

My photo still won't go under 20KB — what can I do?

Make sure the output format is JPEG or WebP: PNG is lossless and often can't reach small targets. For very small targets, also reduce the pixel dimensions under Resize. The tool already shrinks dimensions automatically as a last resort.

Will compressing to 20KB make my photo blurry?

For a passport-style photo or signature, usually not noticeably. For a large, detailed photo, a target this small needs smaller dimensions, so it suits portal uploads better than prints.

Are my photos uploaded to a server?

No. Compression runs entirely in your browser — your photos never leave your device. See the Privacy Policy.
