Compress PDF to 20 MB online — free and exact

Need a PDF under 20 MB? This free tool automatically reduces your PDF until it fits within 20 MB, 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 20 MB target is reached — so you get the exact size limit you need without trial and error. A 20 MB target is ideal for email attachments, shared scanned documents and multi-page reports that are too heavy to send or upload. Compress your PDF to 20 MB to send it faster without splitting it into pieces.

Frequently asked questions

How do I compress a PDF to 20 MB?+

Upload your PDF above and click "Compress to 20 MB". The tool automatically lowers the resolution and image quality of each page just enough to fit within 20 MB, then offers the file for download. Everything happens in your browser, so your document is never uploaded.

Is compressing a PDF to 20 MB 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 20 MB?+

To reach a small target like 20 MB, pages are re-rendered as optimised images, so very fine detail softens. The tool always keeps the highest quality that still fits 20 MB, 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 20 MB 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 20 MB?+

Some PDFs with many pages or dense text can't physically reach 20 MB 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 20 MB.
