How it works

1. Pick the tool for your task

Browse the tool library or use its search and category filters. Each tool has a short guide and notes about its limits.

2. Use a current browser

JavaScript must be enabled. A current version of Chrome, Edge, Firefox or Safari is recommended. File format support and device events can vary by browser. If a file cannot be opened, the tool will tell you.

3. Work locally

The website delivers the tool code to your browser. Your browser then processes your chosen files or input. Large tasks use your device’s memory and may take time; start with smaller files on mobile.

4. Save and check your result

Use the download button to save an output file. Check dimensions, page order and appearance, or scan a QR code with your phone. Unsaved results are not kept when you close or reload the page.

Libraries and licenses

PDF tools use pdf-lib. The QR generator uses qrcode-generator. Both are distributed under the MIT license. License copies are included with the site source.
