🔒 Processed in your browserAbout Compress PDF
Compress PDF makes large PDFs smaller, which helps when a website or email has a size limit. It works best on scanned documents and image-heavy files. Each page is redrawn as an optimised image at the quality you pick. Your files are processed on your own device. Nothing is uploaded to our servers.
How to use Compress PDF
- Choose the PDF you want to make smaller.
- Pick a level: Light keeps the most detail, Strong gives the smallest file.
- Press “Compress PDF”, check the new size and download.
Frequently asked questions
How much smaller will my PDF get?
Scanned PDFs often shrink by 50–90%. PDFs that are mostly plain text are already small and may not shrink much.
Will I still be able to select text?
Compression turns pages into images, so text is no longer selectable. Keep the original if you need to copy text from it.
Which level should I use for government form uploads?
Start with Medium. If the file is still over the limit, try Strong. Check the preview size before downloading.
