Files stay in your browser
PDF, image, and text tools process what you open on your device. Files are not uploaded. Page views are counted with Google Analytics.
Runs in the Browser
Text, images, and PDFs are processed in your browser. The file or text you open is not uploaded to our servers.
Page View Analytics
Google Analytics counts page views and sets cookies. The text and files you process in a tool are not sent to us or included in those page-view stats.
Processed on Your Device
The tools run in your browser, so speed depends on your device. PDF tools and HEIC to JPG also download a library from jsDelivr before they can run.
