Why foldly?

Processed in your browser

For most tools, your files never leave your device. Works offline once the page is loaded.

No sign-up required

Just click and go. An account is optional — it gives you higher limits and a private history.

Ad-free and no tracking

A private, non-commercial project. No ads, no cookies beyond your language preference, no third-party scripts.

How it works

  1. 1

    Choose a file

    Via drag-and-drop or the file picker. Many tools accept multiple files.

  2. 2

    Processed in your browser

    Everything happens locally via WebAssembly (pdf-lib, pdf.js). Your file is not uploaded.

  3. 3

    Download or share

    Result is ready instantly. On mobile the native share sheet opens with "Save to Files".

Exception: Office conversion, OCR and strong compression need a server. Files are sent encrypted, processed immediately and deleted within 15 minutes — never analysed, never stored.

Frequently asked

For most tools, entirely in your browser — files never leave your device. For the three server tools (Office conversion, OCR, strong compression) the file is sent to our server in Germany, processed immediately, and deleted within 15 minutes.
