Your documents never leave your device

Every tool above runs locally using your browser’s own processing. There is no upload, no server copy and no document content in analytics.

  • Local processing

    PDF parsing, rendering and editing happen in this tab and a sandboxed worker.

  • Scripts never run

    Embedded PDF JavaScript and XFA are ignored, so documents can’t act on their own.

  • Passwords stay in memory

    Passwords are used to decrypt in-tab and are never written to storage.

  • You control drafts

    Optional browser drafts stay on this device; turn them off or delete them any time.

Fast on large files

Pages render lazily and heavy work runs in a background worker, so 500-page documents stay responsive.

Faithful output

Untouched documents download byte-for-byte. Edited files keep bookmarks, metadata and form fields.

Real page management

Reorder, rotate, duplicate and insert pages across documents, with unlimited undo.

Keyboard first

Shortcuts for every common action, full keyboard navigation and screen-reader labels.
