Image to PDF Under 20 KB online — free and exact

A 20 KB ceiling is the kind of hard limit exam boards, government job portals and admission forms put on document uploads. Scanned pages photographed on a phone land at 2–5 MB each, so a straight Image-to-PDF conversion is rejected immediately. This page converts and compresses in one step so the PDF lands under 20 KB.

Frequently asked questions

How do I convert Image to PDF under 20 KB?+

Add your Image files above and press "Convert to PDF under 20 KB". The tool builds the PDF and automatically lowers the resolution and JPEG quality just enough to fit 20 KB, then offers it for download.

Can I combine several images into one PDF?+

Yes. Add as many images as you like — each becomes one page, in the order you added them, and the whole document is compressed to fit 20 KB.

Is converting Image to PDF at 20 KB free?+

Yes — completely free, no watermark, no sign-up and no daily limit.

Will the PDF still be readable at 20 KB?+

The tool always keeps the highest-quality version that still fits 20 KB. It tries full resolution first and only scales down when it has to, so text in scanned documents stays legible. If 20 KB is genuinely too small for the number of pages, it tells you the smallest readable size instead of returning something unusable.

Are my documents uploaded anywhere?+

No. The conversion runs entirely in your browser — your Image files and the finished PDF never leave your device, so ID documents and certificates stay private.
