Make a PDF smaller without wrecking it

Email attachments and upload forms often cap files at a few megabytes. Compress PDF re-encodes the photos inside your document and leaves the text and drawings sharp and selectable. Pick Strong, Recommended or Light — or type the size you need, like 500 KB, and get the best quality that fits. It all runs in your browser.

  • Your files stay on your device

    Compress PDF runs in your browser, so nothing is uploaded — not the file, not even its name.

  • Free, with no sign-up

    No account, no watermark on your files and no daily limit for normal use.

  • Up to 20 files at once

    Each file can be up to 100 MB. Large or scanned files simply take a little longer.

  • Works on every device

    Windows, Mac, Linux, iPhone, iPad and Android, in any modern browser. Nothing to install.

Good to know

Yes. Choose a target size of 10 KB or more and pdfconva finds the best quality that fits. If a file can’t get that small and stay readable, you get the smallest readable version and a note saying so.

It depends on what is inside. PDFs full of photos often shrink by 50–90%; text-only PDFs are already small and change little. The result screen shows the exact before and after size.

No. Only images are re-encoded. Text and vector drawings stay sharp and can still be selected and searched.

Each file can be up to 100 MB, and you can add up to 20 files at once. Large or scanned files simply take a little longer.
