Compress PDF online free — no upload, no size limit

PDF tools FAQ

How do I compress a PDF for email?

Drop the file on this page, choose Recommended or High, and download. Recommended keeps text selectable; High makes the smallest PDF (pages become images). There is no size cap on our side.

Does High compression keep text selectable?

Low and Recommended keep text and re-encode embedded images. High flattens each page to an image for maximum size reduction, so text will not stay selectable.

Is this PDF compressor really free with no upload?

Yes. Compress PDF runs in your browser. We never receive the file, and there is no daily limit or watermark.

Is it safe to compress or convert a PDF online?

Yes — on UnlimitedPDF.app the file never leaves your device. Compress PDF, merge PDF, split PDF, and PDF to Word all run in your browser. We cannot see your documents because they are never uploaded to a server.

Is there a free PDF compressor with no file size limit?

UnlimitedPDF does not cap file size or daily use. There is no sign-up and no watermark. The only ceiling is your browser’s memory. Very large PDFs are more reliable on a desktop than on a phone.

Do I need an account to merge PDF files or convert PDF to Word?

No. Every tool works without an account: compress PDF, merge PDF files, split PDF, JPG to PDF, PDF to JPG, resize image, and PDF X-Ray. Optional sign-in never unlocks a paid tier — there isn’t one.

How is UnlimitedPDF different from iLovePDF or Smallpdf?

iLovePDF and Smallpdf typically upload your file, then limit size or daily use unless you pay. UnlimitedPDF is a free online PDF editor toolkit that processes locally — no upload, no size cap, no watermark. The tradeoff is your browser’s RAM, not a subscription.

Can I compress a PDF without uploading it?

Yes. Drop the PDF on Compress PDF, pick Low, Recommended, or High, and download. Re-encoding happens in this tab. Same for merge, split, and convert — nothing is sent to our servers because there is no file-upload endpoint.
