How much can I compress my PDF?

Compression results vary based on your PDF content and chosen quality level. PDFs with many images typically achieve 50-80% reduction, while text-heavy PDFs may see smaller reductions. The tool provides three quality levels for you to balance file size vs. quality.

Will compression affect PDF quality?

Yes, this tool converts PDF pages to compressed JPEG images. Text will no longer be selectable, but remains readable. Higher quality settings preserve more detail, while lower settings provide maximum compression. This tool is ideal for scanned documents or image-heavy PDFs.

Is this tool free to use?

Yes! This tool is completely free with no hidden costs, subscriptions, or limitations. Use it as often as you need.

Do I need to create an account?

No account needed. The tool works entirely in your browser without requiring signup or personal information.

Absolutely. All processing happens locally in your browser. Your data never leaves your device and is not stored on any server.

What's the maximum file size I can compress?

The tool accepts PDFs up to 100MB. Files larger than 50MB will show a warning as they may take longer to process, but will still work.
