Compression FAQs

Frequently Asked Questions

1 Will my PDF text get blurry or unreadable?
No. Text layers and vector graphics are composed of math formulas and are not compressed as raster graphics. Your text remains sharp, clean, and zoomable at any ratio.
2 What is the Recommended Compression level?
The Recommended setting downsamples embedded images to roughly 150 DPI and uses balanced compression algorithms. This gives the best ratio reduction (often up to 60-80%) while maintaining high visual layout quality.
3 Can I compress scanned PDFs?
Yes. Scanned PDFs are typically composed entirely of raw image pages and are normally very large. Compressing them downscales these high-res background images, leading to dramatic size reduction.
4 Is my confidential file safe when compressing?
Yes, completely. Compression algorithms are executed locally on your computer inside your web browser. Your document is processed in real time in your client environment, keeping files 100% private.
5 Does compressing strip hyperlinked references?
No. Document hyperlinks, interactive forms, annotations, bookmarks, and formatting frameworks are fully preserved. Only resource objects (images, fonts, unused streams) are targeted for optimization.
