How do I compress a photo to exactly 20 KB?

Upload your photo, choose the 20 KB preset (or type 20), and click compress. The tool adjusts JPEG quality to land at or just under 20 KB.

Are my photos uploaded?

No. Compression runs entirely in your browser with the Canvas API. Your photo never leaves your device.

Why do application portals limit file size?

Many government, exam, and visa portals cap uploads (often 20–200 KB) to save storage and bandwidth. A photo over the limit is rejected at submission.

Will compressing reduce quality?

Lower target sizes mean more JPEG compression and some quality loss. Choose the largest size the portal allows for the best balance of quality and compliance.

Can I hit any custom KB value?

Yes. Beyond the presets, type any target in KB and the tool searches for the matching quality.

What if I cannot reach a very small size?

Very small targets on a high-resolution photo may need downscaling first. Crop or resize the image, then compress for the smallest files.

What format is the output?

A JPEG, which gives the smallest files for photos and is accepted by virtually every application portal.

Should I crop to size before compressing?

Yes — crop to your required passport or ID dimensions first, then compress, so the final file matches both the size and the KB limit.

How it works

Many application portals reject photos above a strict file-size limit, such as 20 KB or 100 KB. This tool binary-searches the JPEG quality to land your photo just under the target size you choose, all in your browser. Pick a preset or type an exact KB value and download a compliant file in seconds — nothing is uploaded.
