PDF Compressor

What this tool does

Re-save compatible PDFs with optimized object streams and cleaned metadata to reduce file size where possible.

When to use it

Use it before email uploads, form submissions, document sharing, or storing many PDF files locally.

Privacy and local processing

Compression runs in the browser and does not require uploading the document.

Limitations

This is browser-side repacking, not a full Ghostscript-style optimizer. Scanned PDFs and already optimized PDFs may not shrink much.

Tips

For image-heavy PDFs, first reduce source image size before creating the PDF, then compress the final file.
