About PDF Compressor

PDF Compressor is a free, browser-based tool that reduces PDF file sizes without uploading your documents anywhere. Everything runs locally on your device — your files are never sent to a server.

Built for people who need to share PDFs over WhatsApp, email, or cloud storage with tight size limits. No account, no payment, no limits.

How it works

The tool renders each PDF page to a canvas in your browser, compresses the output as a high-quality JPEG image, and assembles a new PDF from those images. This achieves significant file size reduction while preserving the visual layout.

Because the output PDF is image-based, text may not be directly selectable. Use the Best Quality setting if you need maximum text fidelity.
