SqueezePDFCompress PDF for a signaturefree & private
Scanned your handwritten signature into a PDF and the form won't accept it because the file is too big? This tool shrinks a signature PDF down to the tiny size application and exam forms demand, and it all happens in your browser. If your signature is still a raw JPG or PNG, place it in a PDF first, then compress it here.

Getting a signature PDF under 20 KB
This page opens on the Balanced quality preset (72 DPI), but check your form and switch to Target size and pick the exact figure it asks for. Balanced preset tries progressively lower quality levels and keeps the sharpest version that still fits, downsampling only the embedded scan. Nothing is uploaded - the whole process runs on your device.

Frequently asked questions
How do I compress a signature PDF to a very small size?+
Load the PDF with your scanned signature, leave Balanced preset on, and set the target to the size your form needs (switch to Target size and pick the size your form needs). The tool tests several quality levels and saves the clearest one that fits under your limit.
How small does a signature usually need to be?+
It varies by form, so always use the exact figure your form states. Signatures are often required very small, commonly somewhere around 10-20 KB, though some forms allow more. Type the precise number and let the tool match it.
Is my signature private and safe?+
Yes. Compression runs entirely in your browser through . Your signature file is never uploaded and never leaves your device, and it works offline once the page has loaded.
Will my signature still be legible at such a small size?+
The tool keeps the highest-quality version that fits your target, so it never shrinks more than necessary. A signature is mostly simple lines, so it usually stays clearly readable even at very small sizes.
Is it free and do I need an account?+
It is completely free with no sign-up, no watermark, and no file limits. Just open the page and compress your signature PDF.
