PDF Compressor — Smaller Files, Same Document
Oversized PDFs are a pain to email, upload and store. This free PDF compressor shrinks your documents by optimizing their contents — choose a compression level that balances file size against quality, then download the smaller file.
Upload a PDF up to 100MB, pick your compression level, and hit compress. Your file is sent to our server for processing and returned to you as a download — so avoid uploading documents with sensitive or confidential content.
Three compression levels
Pick light, medium or strong compression depending on whether you need maximum quality or the smallest possible file.
Up to 100MB per file
Compress large reports, scans and ebooks that email providers would reject — no account or signup needed.
How it works
Your PDF is uploaded to our server, compressed there, and the result is sent back for download. Files are processed for compression only. Because uploads leave your device, do not use this tool for sensitive documents.
How to use
- Drag and drop your PDF (max 100MB) into the upload zone.
- Choose a compression level.
- Click Compress PDF.
- Download the smaller file.
Frequently Asked Questions
How does PDF compression work?
The tool re-encodes images and optimizes the file structure on our server, removing redundant data while keeping text and layout intact.
Will compression reduce the quality?
It depends on the level you choose. Light compression keeps quality nearly identical; stronger levels shrink images more aggressively. Text always stays sharp.
Is my PDF uploaded to a server?
Yes. Compression happens on our server, so your file is uploaded for processing and the compressed version is returned as a download. Avoid sensitive documents.
What is the maximum file size?
100MB per file.
Do I need an account?
No. Compression is free with no signup required.
