About the Compress PDF
Make a large PDF smaller so it is easier to email, upload or store. Choose a compression level, and the tool rebuilds the PDF at a lower size.
It works by re-rendering each page as an optimised image, which is very effective for scanned documents and image-heavy PDFs. You can compare the before and after size and savings.
Everything is processed in your browser, so your PDF is never uploaded to a server.

Frequently asked questions
- Will the text still be selectable?
- No. Compression re-renders each page as an image, so text becomes non-selectable. This gives the biggest size reduction and is ideal for scanned or image-heavy PDFs.
- How much smaller will my file be?
- It depends on the content and level you choose. Image-heavy and scanned PDFs shrink the most. The tool shows the exact savings after compressing.
- Is my PDF uploaded?
- No. Compression is done locally in your browser, so your document stays private.
