Shrink PDF files without losing your work
Use this compressor when a PDF is too large to email, upload, or share — a scanned document, a photo-heavy report, or a form export. Pages are re-optimized locally in your browser, so the file gets smaller without ever leaving your device.
Best used for
- • Fitting a scanned document under an email attachment limit
- • Uploading PDFs to portals or forms with strict file-size caps
- • Sending photo-heavy PDFs quickly without installing extra software
Privacy notes
- • Compression happens locally in your browser
- • The PDF is not uploaded to any server
- • Your original file on disk is never modified
Better results
- • Start with Balanced compression for most everyday documents
- • Use Maximum compression only when a strict size limit forces it
- • Keep your original file if you need to copy text from the document later

PDF Compressor FAQs
How does the PDF compressor reduce file size?Show
Each page is saved as an optimized image — the same lossy compression approach online PDF tools use. Your document looks the same, just lighter. Pick a compression level to balance quality and size.
Will my PDF still look the same after compression?Show
Yes. The pages keep their exact layout and dimensions. Text in the compressed copy is no longer selectable, so keep your original if you need to copy text from it.
Is my PDF uploaded to your servers?Show
No. Compression runs entirely in your browser tab. Your file is never sent or stored anywhere, and your original file on disk is never modified.
How much smaller will my PDF get?Show
It depends on the content. Scanned documents and photo-heavy PDFs often shrink by 50–90%. PDFs that are already highly optimized may see smaller savings — try Maximum compression for the smallest result.
Can I compress just a few pages instead of the whole PDF?Show
Yes. Use our free Split PDF tool to extract the pages you need first, then compress the result here. Both tools run locally in your browser with no uploads.
