FAQ
- Can UnderLimit make a PDF exactly 25 MB?
- UnderLimit compresses toward your 25 MB target. Output is typically at or under the limit when the document allows; extremely constrained files may need a stronger mode or a higher target to stay readable.
- Can I compress multiple PDFs to the same target?
- Yes. You can upload up to 20 PDFs in one batch, set a shared target, and download individual files or a ZIP when processing finishes.
- Are my files kept forever?
- No. Results are available for a limited time (about 48 hours) and then expire automatically. We do not train models on your documents.
