Frequently asked questions
Are my files uploaded?
No. Your browser reads the selected file and creates the result in browser memory. PDF Calm does not provide a user-file upload endpoint.
What are the limits?
The interface is designed for files up to 500 MB and documents up to 2,000 pages. Device memory can impose a lower practical limit.
Is compression lossless?
No. Local compression may rebuild pages as images. Inspect forms, links, bookmarks and small text before using the result.
Can you unlock a password PDF?
No. PDF Calm does not crack or bypass passwords. Use a copy with a password you own.
Who is PDF Calm for?
It is for private browser workflows involving office documents, study material, scans, printing and everyday PDF cleanup.
Privacy first
Files are read locally through the browser File API. They are not sent to PDF Calm.
