How it works

Since pdf-lib and pdfjs-dist both ship as JavaScript and run entirely in your browser, there is no account, no upload step, and no usage cap to enforce. Lossless mode lets pdf-lib re-serialise the document with shared object streams, and the image-quality modes use pdfjs-dist to rasterise each page on a Canvas before pdf-lib stitches the JPEGs into a slimmer PDF. The output downloads as soon as compression finishes.

Processing runs in your browser

No account is created because our servers are not involved. The compression libraries run as JavaScript in this tab, processing your file in-memory and writing the result directly back to your downloads folder, with no infrastructure to register against. You can check this yourselfin your browser's DevTools Network tab.

To stitch multiple PDFs into one before compressing, try merge PDF. For pulling out a subset of pages, use split PDF. To extract pages as standalone images, see PDF to image.

Frequently asked questions

Why do other PDF tools require an account?
Server-based tools process your file on their infrastructure, so they create accounts to manage storage, usage limits, and billing. Because this tool runs entirely in your browser, there are no server costs and no reason to collect your information.
Is this tool completely free?
Yes. No account, no subscription, no per-file fee. The tool runs in your browser and has no server costs to recover.
Will a watermark be added to my PDF?
There is no watermark. The compressed PDF is identical to the original except for the reduced file size.
Is my file private?
Yes. All processing runs in your browser using pdf-lib. Our servers are not involved at any point.
