Compress PDF to 10 KB online — free and exact

Need a PDF under 10 KB? This free tool automatically reduces your PDF until it fits within 10 KB, then lets you download it. It works by intelligently re-rendering each page and tuning quality and resolution in your browser until the smallest readable file that meets your 10 KB target is reached — so you get the exact size limit you need without trial and error. A 10 KB limit is one of the strictest you will meet online — it is the cap used by many Indian government job portals (SSC, UPSC, state PSCs), online exam application forms (NEET, JEE, GATE) and visa or passport document uploads. This tool squeezes a scanned PDF down to 10 KB so a rejected "file too large" upload finally goes through.

Frequently asked questions

How do I compress a PDF to 10 KB?+

Upload your PDF above and click "Compress to 10 KB". The tool automatically lowers the resolution and image quality of each page just enough to fit within 10 KB, then offers the file for download. Everything happens in your browser, so your document is never uploaded.

Is compressing a PDF to 10 KB free?+

Yes — completely free with no watermark, no sign-up and no daily limit. You only need an account if you want your history saved.

Will the quality drop when I compress to 10 KB?+

To reach a small target like 10 KB, pages are re-rendered as optimised images, so very fine detail softens. The tool always keeps the highest quality that still fits 10 KB, so text stays clearly legible for form and portal uploads. If you don't need an exact size, use the standard Compress PDF tool for lighter, higher-quality compression.

Is it safe to compress confidential documents to 10 KB here?+

Yes. This tool runs 100% in your browser — your PDF never leaves your device and is never sent to any server, so ID cards, certificates and bank statements stay private.

What if my PDF can't be compressed all the way to 10 KB?+

Some PDFs with many pages or dense text can't physically reach 10 KB while staying readable. In that case the tool produces the smallest readable file it can and shows you the achieved size — often you can then split the PDF or remove unneeded pages to get under 10 KB.
