Compress a PDF for free, with no signup

Search for a free PDF compressor and the first results usually turn out to be free trials: two conversions, then a paywall, or an account before you can download. PDF Flourish is free in the simpler sense — the whole tool runs in your browser, so there is nothing to gate behind an account.

Why other tools ask for your email

Server-based tools pay for every file they process, so they limit free use and convert heavy users into subscribers. The signup wall is how they enforce the limit. A browser-based tool has no server cost per file, which is why it can be unlimited without needing your email address.

What genuinely free looks like

  • No account or email address requested at any point.
  • No watermark stamped on the output.
  • No daily limit, page limit or file queue.
  • The file is processed on your device, not uploaded.

Getting the best result

Add your PDF below, start at the medium level and check the size. For anything going to print, use light instead — medium is tuned for screens. And because nothing is uploaded, you can safely compress documents you would never paste into a random website, like tax returns or medical letters.

  2. 2Pick a level and run the compression.
  3. 3Check the reported size and the legibility of the result.
  4. 4Download the file; your original stays untouched.

Frequently asked questions

What is the catch?
There is none. The site is funded by advertising, and the processing runs on your own device, so heavy use costs us nothing to serve.
Is there a file size limit?
Only what your device can handle. A desktop copes with very large scans; phones are slower past a few hundred pages.
