Compress PDF to 20 MB
Twenty megabytes leaves more room for readable scans. Use UnderLimit when a portal allows ~20 MB and you want a controlled target instead of a vague “make smaller”.
Large colour scans often fit 20 MB with Preserve; only push Strong if preflight says you still exceed the limit.

FAQ
- Can UnderLimit make a PDF exactly 20 MB?
- UnderLimit compresses toward your 20 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.
