Common questions
Why compress to 20 KB?+
A 20 KB cap is one of the most common limits on exam and government application forms — especially for scanned signatures and passport photos. This gets you under it in one click.
Will a signature still be readable at 20 KB?+
Yes. Signatures and line art compress very well, so 20 KB is usually plenty. For a busy colour photo we also gently reduce the dimensions so it still fits while staying usable.
Is my image uploaded anywhere?+
No. This runs entirely in your browser using your device's own processor — your image never leaves your computer or phone. Ideal for ID photos and signatures you'd rather not upload.
What if it can't reach 20 KB?+
For large or detailed images we reduce the dimensions too. If it still can't fit while staying usable, we give you the smallest version and tell you — never a broken file.
Which formats work?+
JPG, PNG and WebP. The result is a JPG (or WebP) since those compress to a precise size.
Is there a limit or watermark?+
No watermark, no signup, free — and since it's all in your browser, no upload size limits either.
