PDF Compressor
Desktop App

PDF Compressor uses two powerful engines to reduce file size: (1) pikepdf for lossless stream optimization that works without quality loss, and (2) Ghostscript (optional) for image downsampling when you need maximum compression. You select your compression level (Light, Medium, or Strong), and the app intelligently chooses the best compression method for each file.

It depends on your compression level. Light mode uses lossless compression — no quality loss at all, just stream optimization. Medium and Strong modes may reduce image resolution slightly for more aggressive compression. You can always test with one PDF first and keep the original if you're not satisfied with the results.

Yes, completely. PDF Compressor works 100% offline — all compression happens on your PC. Your files never leave your computer, never upload to the cloud, and never touch any external servers. This is why PDF Compressor is safer than online tools for sensitive documents.

Absolutely! PDF Compressor supports batch processing. Select as many PDF files as you want, choose your compression level, and click Compress. The app will process all files automatically. This is perfect for businesses, government agencies, and anyone dealing with bulk documents.

No, you do not need internet at all. PDF Compressor works 100% offline. Download the app once, and use it anytime, anywhere — even on airplanes, in remote areas, or on networks without connectivity. This also means better privacy and faster compression speeds.

Light mode uses lossless compression for modest file size reduction with zero quality loss. Medium mode reduces image resolution to 150 dpi for better compression. Strong mode aggressively compresses to 72 dpi for maximum file size reduction. Choose Light for documents where quality matters most, Medium for balanced compression, and Strong for email or storage where file size is critical.

No installation required. PDF Compressor is a portable .exe file. Just download, extract the ZIP, and double-click the .exe to run. No registry changes, no system modifications. You can even store it on a USB drive or cloud storage for portable access across computers.

Simply delete the .exe file. That's it. No leftover files, no registry entries, no uninstaller needed. PDF Compressor is completely portable with zero system footprint.

Yes, 100% free, forever. No hidden costs, no premium tier, no subscriptions, no ads, no watermarks. PDF Compressor is completely free to download and use. It's part of the GoAndUse suite of free desktop tools.

No problem. PDF Compressor automatically falls back to its built-in compression engine (pikepdf). The app will still compress your PDFs effectively — you just won't get the absolute maximum compression that Ghostscript provides. The app never breaks; it always has a backup plan.

PDF Compressor works with standard PDF files (.pdf). It supports scanned PDFs, text PDFs, and PDFs with images. If you need to convert other formats (like Word, Excel, or images) to PDF first, you can use other GoAndUse tools for that conversion.

Currently, PDF Compressor is available for Windows 10 and Windows 11 (64-bit) only. Mac and Linux versions are not available at this time. Check back later for updates.
