Why compress a PDF?
Scanned documents balloon in size fast — a few phone photos saved as a PDF can be 10–20MB. Most upload forms and email attachments cap well below that, so the file gets rejected until you shrink it.
- Job & government portals: upload a resume or form under a strict limit like 200KB or 500KB
- Email attachments: get a heavy scan down to 1MB so it actually sends
- University & visa forms: fit certificates and ID scans into tight caps like 100KB
- Storage & sharing: lighter PDFs open faster and take less space

FAQ
Common questions
How do I compress a PDF online for free?
Drop your PDF above, choose a compression level (Recommended works for most files), then hit Compress PDF and download the smaller version. It's completely free and nothing is uploaded — the whole process runs in your browser.
Is my PDF uploaded to a server?
No. Your file never leaves your device. The tool uses JavaScript to render and re-save the PDF locally, so it stays completely private — safe for bank statements, ID scans, and confidential documents.
Will there be a watermark on my PDF?
Never. The compressed PDF comes out clean, with no watermark, stamp, or branding added anywhere.
How much can I shrink a PDF?
Scanned or image-heavy PDFs usually shrink a lot — often 60–90% smaller. PDFs that are mostly plain text are already compact, so they won't shrink much; the tool will tell you when a file is already well optimized.
Can I compress a PDF to an exact size like 200KB?
Yes. Use a target page such as compress PDF to 200KB or 100KB — the tool automatically searches for the smallest file at or under that limit.
Does it work on iPhone and Android?
Yes. It runs in any modern mobile browser, so you can compress a PDF straight from your phone before uploading or emailing it.
Why is my compressed PDF slightly blurry?
Strong compression re-saves each page as a lower-quality image, which can soften fine text. If sharpness matters, pick "Less compression" for a lighter squeeze, or a higher KB target on a size page.
Is this tool really free?
Completely. No account, no watermark, no daily limit. Files stay on your device and the tool is free to use as often as you like.
