Compress PDF reduces the file size of a PDF so it fits email limits and upload forms. Choose Lossless to rebuild the file structure and strip metadata without touching text or graphics, or Balanced and Maximum to re-render pages as JPEG images at a lower resolution for much bigger savings. If a mode would make the file larger, the tool keeps the smaller version automatically — and all of it runs in your browser.
Open Compress PDF
Launch Compress PDF directly in your browser — there is nothing to download, install, or configure first.
Add your PDF
Drag and drop or choose the PDF you want to work with. It loads straight into Compress PDF and stays on your device.
Set your options and run it
Choose the pages, order, or output you need, then run Compress PDF. Everything is processed locally in your browser.
Use Lossless for documents with lots of text that must stay crisp and selectable. Use Balanced for scans and photo-heavy PDFs you only need to view or share; Maximum gives the smallest file at visibly lower quality.
Already-optimised PDFs have little to remove. In that case the tool keeps your original file rather than producing a bigger one.
With Lossless, yes. Balanced and Maximum turn each page into an image, so text is no longer selectable.
No. Compression runs on your own device; the document never leaves your browser.
Yes. Compress PDF is completely free, with no account, no paywall, and no usage limits.
No. Compress PDF works instantly in any modern web browser — there is no software to install, no extension, and no sign-up.
