About this converter
Use Compress PDF with confidence
Compress PDF helps reduce file size for email, upload portals, and everyday sharing. It is best for distribution copies where smaller size matters more than preserving a print-production master.
Why use this tool?
- Make large PDFs easier to email or upload.
- Reduce image-heavy files while keeping text readable.
- Create a smaller copy without changing the original file on your device.
Supported formats
PDF size is often driven by scans and high-resolution images. Text-heavy PDFs may already be compact, so the size reduction can be modest.
