Frequently Asked Questions

How much smaller will my PDF be?

Results vary depending on the content. PDFs with images typically see 40-80% reduction. Text-only PDFs may see less improvement as they are already small.

Will compression affect text quality?

Text remains sharp at all compression levels. Only images and embedded graphics are affected by the DPI setting.

What if my PDF is already optimized?

If compression would make the file larger, we return the original file and let you know it was already optimized.

Is my data secure?

Yes. Your PDF is processed in memory and immediately discarded after compression. No one has access to your files.
