SqueezePDFCompress PDF on Macno install needed
macOS can export a smaller PDF from Preview, but the quality is hard to control and it often barely shrinks scanned files. This tool gives you real control in the browser, with no software to install and nothing uploaded.

A better option than Preview's Reduce File Size
Preview's built-in Quartz filter uses one fixed setting and frequently makes scanned PDFs blurry or barely smaller. Here you can pick a quality preset or a target size, and the tool tries multiple levels to keep text sharp while cutting image weight. It runs right in Safari, Chrome or Firefox — your file never leaves the Mac.

Frequently asked questions
How do I compress a PDF on Mac without Preview?+
Open this page in any browser, drop your PDF in, and download the compressed copy. It gives finer control than Preview's Reduce File Size filter and doesn't degrade text.
Why is Preview's Reduce File Size so blurry?+
Preview applies a single low-resolution Quartz filter to every image. This tool lets you choose the quality or a target size, so you keep the highest quality that still meets your limit.
Do I need to install anything?+
No. It's a web page — no app, no Homebrew, no Ghostscript install. Everything runs in the browser.
Are my files private?+
Yes. Compression is local to your Mac; nothing is uploaded to a server.
Is it free?+
Completely — no account, no watermark and no limits.
