Does compressing a PDF reduce quality?

RedaktPDF optimizes images and removes unnecessary metadata while preserving visual quality. Text and vector graphics remain sharp.

How much smaller will my PDF be?

Results vary depending on the content. Image-heavy PDFs can shrink by 50-80%. Text-only PDFs may see smaller reductions since text is already compact.

Why is my PDF so large?

Common causes include high-resolution embedded images, duplicate fonts, and metadata bloat. Compression addresses all of these.

Is the compression free?

Yes. PDF compression is available to all users, including anonymous uploads. No sign-up or payment required.
