Compress PDF
Reduces a finished PDF before you send it by email, submit it through a form, or keep a smaller archive copy. Use the portal file-limit presets for IRCC-style 2 MB, USCIS 12 MB, HealthCare.gov 10 MB, or a generic 5 MB target before downloading the result.
Runs in your browser. The file and result are not sent to Utilio servers.
Compress PDF
Runs locally in your browser. Your PDF stays on this device.
Compression
Keeps selectable text and links where possible. Best for already digital PDFs.
Use the normal quality setting and compare the result yourself.

What Compress PDF does
Use Compress PDF when you need to send contracts, scans, reports, or coursework under a strict file-size limit.
When to use it
- Send contracts, scans, reports, or coursework under a strict file-size limit.
- Prepare multi-page PDFs for document portals that reject large files or unsafe file names.
- Work toward government, healthcare, visa, job, and court form targets without sending the PDF to Utilio.
How to use it
- Add the PDF and wait for the local preview to read the page count and size.
- Choose a quality level or pick a portal file-limit preset when a form has a hard cap.
- Download the compressed PDF, check the size result, and compare it with the original before replacing anything.
What to check
- Zoom into scanned pages, signatures, and small print after compression.
- Keep the original when the PDF may be needed for legal or print work.
- Portal rules can change, so check the final account or form instructions before sending.
