Compress PDF - Reduce Size

Compress PDF when a scanned document or image-heavy file is too large to email, upload or store conveniently. Choose the level of detail you need and prepare a smaller version of your document in a browser-based tool.

Compress PDF with three compression levels: Balanced for everyday sharing, Strong when a smaller file matters most, and Light when you want to retain more fine detail. You can compare the original and resulting file sizes before deciding whether the new document meets your needs.

To Compress PDF, select one document, pick a level and start processing. The tool accepts one PDF at a time, up to 40 MB and 100 pages. This method is especially useful for scans, photo-rich reports and documents with large embedded images. A file made mostly of text or already optimized may not become smaller; the tool keeps the original bytes when its rebuilt version would be larger.

Compress PDF without sending the selected document to the website's server: page rendering and reconstruction happen in the browser. An internet connection is needed to access the online tool. Compress PDF creates pages from optimized images, so text selection, search, active links, forms and accessibility information may not survive the process.

Use Compress PDF for attachments, online applications and personal document storage. Before sharing a result from Compress PDF, inspect small print, charts and signatures, and keep your original file if you may need to edit it. Compress PDF gives you a practical quality-versus-size choice, not a guarantee of a specific final file size.
