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 processing costs to recover and no reason to collect your information.

Is this tool completely free?

Yes. There is no account, subscription or per-file fee. The tool runs in your browser, so there are no processing costs to recover.

Will a watermark be added to my PDF?

There is no watermark, and nothing is added to your pages. Lossless mode keeps the content as it is; the image modes turn each page into a JPEG image, so its text is no longer selectable.

What is the compressed file called?

It keeps your file name and adds -compressed, so report.pdf downloads as report-compressed.pdf. Your original file is not changed.

Compress PDF: No Account Required

Compress your PDF without creating an account, providing an email address, or signing up for anything. Drop your file, choose a quality level, and download the result. All processing runs locally in your browser.

How it works

Since pdf-lib and pdfjs-dist both ship as JavaScript and run entirely in your browser, there is no account 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 is ready to download as soon as compression finishes.

Processing runs in your browser

The compression libraries run as JavaScript in this tab, processing your file in memory and offering the result as a download when it is ready. Our servers are not involved at any point. You can check this yourself in your browser's DevTools Network tab.
