iPhone PDF → Smaller PDF
Compress PDF on iPhone — no app required
You don't need to install an app to compress a PDF on iPhone. Open Krymp in Safari, pick the PDF from Files or iCloud Drive, choose a quality level and save the smaller PDF back to Files. The file never leaves your device — Safari runs the same WebAssembly compressor as desktop browsers.

Vanliga frågor
Does it work in iOS Chrome?
Yes — Chrome on iOS uses Safari's engine and supports the same flow.
Will my battery drain?
Compression is brief — typically under 10 seconds for a 5 MB PDF.
Account?
Not required.
Privacy?
Files stay in Safari — Krymp can't keep what it never receives.
Big PDFs?
