What is Compress Image to KB?
Compress Image to KB shrinks a photo or signature to an exact target size — like 20 KB, 50 KB, 100 KB or 200 KB — so it passes the strict upload limits on exam, job, passport, bank and government portals. Pick a preset or type any size, and the tool automatically finds the highest quality that fits.
If quality alone can’t get under the limit, it reduces the dimensions step by step until it does, and tells you exactly what it changed. You can also set exact pixel dimensions when a form asks for them. Everything happens in your browser, so personal photos and signatures are never uploaded.
How to use Compress Image to KB
Get it done in 4 simple steps — no installation or account needed.
- Choose or drop your photo or signature (JPG, PNG, WebP or HEIC in Safari).
- Pick a target size such as 50 KB, or type the exact limit from your form.
- Optionally set the exact width and height the form asks for.

Compress Image to KB — frequently asked questions
How do I compress a photo to exactly 20 KB?
Choose the 20 KB preset (or type 20) and add your photo. The tool searches for the best quality that stays under 20 KB and shows the final size before you download.
Why does my image look smaller after compression?
If even low quality can’t reach your target, the tool reduces the dimensions. Very small targets like 10–20 KB usually need smaller images; the result shows the final width and height.
Can I compress a signature?
Yes. Signatures compress very well. If the form specifies dimensions (e.g. 140 × 60 pixels), enter them in the size fields too.
Are my files uploaded to a server?
No. Everything is processed locally in your browser using JavaScript. Your files never leave your device, and nothing is stored on our side.
