Use Compress PDF to shrink your document size while maintaining good readability — directly in your browser.
Step 1 — Select a File
Drop your PDF or click “Select PDF”. Files up to 100MB are supported. Your file never leaves your device.
Step 2 — Pick a Level
- Light: Best visual quality
- Balanced: Recommended for most cases
- Strong: Smallest file size
Optionally toggle Downsample images and Remove metadata.
Step 3 — Compress & Download
Click Compress PDF. Processing uses Canvas/PDF.js/PDF-Lib locally; when finished, the output downloads automatically.
Tips
- For email attachments, pick Strong.
- Keep metadata if you need author/date info preserved.
