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?

Limited by iPhone RAM, but most reports under 100 MB work fine.
