Choose a compression level
All levels currently apply the same safe, lossless optimization pass (pdf-lib object-stream packing). Real-world size reduction depends entirely on your PDF's existing structure — some files shrink noticeably, others barely change.

Frequently Asked Questions
Which compression level should I choose? ▼
"Recommended" gives the best balance for most files. Choose "Best Quality" if your PDF has detailed images you don't want softened, or "Smallest Size" if you just need the file as small as possible for emailing or uploading.
Will compressing my PDF affect its text or layout? ▼
No, compression mainly optimizes embedded images and fonts. Text stays sharp and selectable, and your page layout is left untouched at every compression level.
