PDF Toolkit

Compress PDF

Browser-only

Browser-only structural compression. Best for unoptimized PDFs. Image-heavy scanned PDFs may not shrink significantly. Your file never leaves your browser.

How it works

1. Add one PDF

Choose the source PDF from your device. The file stays in your browser.

2. Optimize

We rewrite the PDF using object streams and optionally strip metadata fields.

3. Download

Save the smaller file with a custom filename. Nothing was uploaded.

Why use this compressor

Browser-only. Your PDF never leaves your device. No upload, no server, no log.

Honest about limits. Server-based tools can re-encode images. This one focuses on structural and metadata savings, which work best on un-optimized PDFs.

Metadata control. Choose whether to strip title, author, and producer fields - useful when sharing files publicly.

Free forever. No signup, no rate limits, no paywall.
