About this tool

Twenty kilobytes is a tight budget, typically asked for signatures and small form photographs. To reach it, the tool lowers JPEG quality step by step, then reduces dimensions if quality alone is not enough, always reporting where it ended up. A few practical notes. Signatures reach 20 KB easily once the paper is whitened, because a flat white background compresses to almost nothing; the dedicated signature tool does that automatically. Photographs are harder, and a busy background is usually the reason a picture will not fit. Cropping tighter to the subject often achieves more than any quality setting, since there is simply less detail to store. If the form specifies pixel dimensions as well, use the exam and job form tool, which handles the size and the KB limit together rather than one after the other.

Frequently asked questions

Is 20 KB enough for a passport photo?

At typical form dimensions of around 200 by 230 pixels, yes. At full camera resolution, no, which is why dimensions are reduced when needed.

My signature will not fit. What helps?

Use Signature Resizer, which whitens the paper first. A flat white background compresses to almost nothing, which usually solves it immediately.

Does it also set the pixel size the form wants?

Use Photo Resizer for Exam and Job Forms if you need both. It applies the pixel dimensions and the KB limit in one pass.

What if the image can't reach 20 KB?

We first lower JPEG quality in small steps, then reduce dimensions only if needed, and always tell you the final size.

Is Compress Image to 20 KB free?

Yes. There's no sign-up, no watermark and no usage limit.

Are my files uploaded to a server?

No. Compress Image to 20 KB runs entirely in your browser. Your files never leave your device and nothing is stored - close the tab and everything is gone.

Which file types can I use?

JPG, PNG, WEBP, GIF, BMP, TIFF, HEIC, SVG, ICO. Files are checked by their actual content, not just the extension, so renamed or damaged files are caught early.

Does it work on my phone?

Yes. It works in modern mobile browsers on Android and iPhone. Heavier jobs (large PDFs, OCR) are faster on a computer.
