Three steps

Can You Compress a PDF Without Software?,without the extra steps.

  1. Open this page in your browser, nothing to download or install.
  2. Select your PDF, or drop it onto the page.
  3. Pick a level, compress, and download.

Why use this tool

Built forthis exact case.

A desktop compressor has to be downloaded, installed and kept updated, and usually only runs on one operating system. This tool runs as a web page instead: open it, select a file, and it works, with the compression happening in your browser rather than on a server.

Need a specific file size instead?

Jump straight to a common target: 100KB, 200KB, 300KB, 500KB, 1MB, 2MB, 10MB. For full manual control instead of a target, use the general Compress PDF tool.

Other ways to use this tool

Compress a PDF for email, for upload, without losing quality, to the smallest size, for free. To cut pages instead of recompressing, use Split PDF, Delete PDF Pages or Extract PDF Pages. Not sure why the file is big in the first place? See the usual causes or how compression works.

The question everybody asks

Is it really free?

Yes. No account, no trial, no watermark on the output, no cap on file size or page count, and no payment step between you and the download button.

It is free because it is cheap to run: your PDF is compressed by your own browser, so there is no upload, no server doing the work and no storage to pay for.

FAQ

Questions peopleactually ask.

Can I compress a PDF without software?

Yes. This page is the software, in the sense that it does the compression, but there is nothing to download or install. It runs as a normal web page.

Do I need to install anything to use this?

No. Open the page in your browser, select a PDF, and compress it. Nothing gets installed on your device.

Does this work on a Mac or a Chromebook?

Yes. Since it runs in the browser rather than as a desktop application, it works the same way on Windows, Mac, Chromebook and Linux.

Is a browser-based compressor different from a desktop one?

The result is a normally saved PDF either way. The difference is where the work happens: a desktop app processes the file on your machine after you install it, this tool processes the file in your browser tab with no install step at all.

Is my file uploaded anywhere?

No. The PDF is opened, compressed and re-saved entirely in your browser tab, with nothing sent to a server.

Will this work on a work or school computer where I cannot install software?

Yes, since there is nothing to install, it works anywhere a normal browser is allowed to run, including machines locked down against installing new software.
