Compress PDF
Reduce PDF file size
About this tool
Reduce the size of a PDF by re-encoding its pages as optimized images. This works best for scanned documents and image-heavy PDFs. Pick a compression level to balance size and quality. Everything runs locally in your browser.
All PDF processing happens in your browser with client-side libraries. Your documents are not uploaded to DevToolDeck servers, which makes this suitable for drafts, contracts, and internal files you do not want to send to a third-party converter.
How to use it
- Choose or drop the PDF file(s) you want to process.

Common use cases
- Prepare documents before sharing or archiving.
- Fix page order or structure without desktop software.
- Handle sensitive PDFs without uploading them.
- Batch small document tasks quickly in the browser.
Frequently asked questions
Will the text still be selectable?
This compressor rasterizes pages into images, so text becomes part of the image and is no longer selectable. It is ideal for scans and image-based PDFs.
Which level should I pick?
"Recommended" is a good balance. Choose "Strong" for the smallest size or "Light" to keep more detail.
Does Compress PDF upload my files or text?
No. Processing is designed to run in your browser. Your inputs are not uploaded to DevToolDeck servers for conversion.
Do I need an account?
No. You can use the tool immediately without signing up.
Is the tool free?
Yes. DevToolDeck tools are free to use in the browser. The site may show ads to keep the service available.
