Frequently Asked Questions

Is this PDF compressor really free?

Yes. This tool is completely free to use with no hidden costs, subscriptions, or premium tiers. There are no watermarks or branding added to your compressed PDFs.

Are my PDF files stored on the server?

Your PDFs are temporarily stored for up to 10 minutes so you can download the results, then automatically and permanently deleted. We never read, share, or process your files beyond compression.

How much can I reduce a PDF file size?

Results vary depending on the content. PDFs with many images typically compress 50–80% with the Screen preset. Text-heavy or already-optimized PDFs may compress less. Our tool will always keep the best result — if compression makes the file larger, the original is kept.

Will compression reduce the quality of my PDF?

The eBook and Printer presets maintain very good visual quality while still reducing file size. The Screen preset reduces image resolution to 72 DPI which may be noticeable on printed output but is perfectly fine for digital use.

What is the maximum file size and how many files can I upload?

You can upload up to 20 PDF files per batch, with a maximum of 100MB per file. There is no limit on how many batches you process.

Does this work on scanned PDFs?

Yes. Scanned PDFs (which are essentially images inside a PDF) often achieve the highest compression rates since the image data is re-compressed at the selected DPI setting.
