Compress PDF — Shrink Your File Without Uploading It
Squire's Compress PDF tool reduces the size of scanned and image-heavy PDFs by re-rendering each page at a smaller footprint, so a bulky file becomes easy to email, upload, or archive. It's built for the PDFs that are actually large: scans, photos, and graphics-dense documents.
Everything runs entirely in your browser. Your file is never uploaded to a server, there are no daily limits, and there's no account or monthly plan to manage. Unlike Smallpdf or iLovePDF, which send your documents to the cloud, throttle the free tier, and charge every month, Squire is a one-time $5 and your file never leaves your computer.
100% private — your files never leave your browser. No upload, no account, no subscription.

Why Squire
Questions
Are my files uploaded when I compress a PDF?
No. Squire runs entirely in your browser, so your PDF is processed on your own device and never uploaded to any server. The file never leaves your computer, which makes it safe for sensitive or confidential documents.
What kinds of PDFs does this compress best?
It works best on scanned and image-heavy PDFs. Squire shrinks them by re-rendering each page, so documents made of scans, photos, or dense graphics see the biggest size reductions. Files that are mostly plain text won't shrink as much, since they're already small.
Is there a file-size limit or daily cap?
There are no daily limits and no per-file caps imposed by a server, because the work happens on your machine. The practical ceiling is your device's own memory. There's no account to create and no subscription — just a one-time $5.
