Supported Browsers

LocallyPDF targets current versions of Chrome, Edge, Firefox, and Safari on desktop and mobile. JavaScript, Web Workers, WebAssembly, and sufficient browser memory may be required by individual tools.

Very large documents, unusually large page dimensions, encrypted files, and older mobile devices may exceed browser resource limits. Closing unused tabs or processing fewer files can help.

The File System Access API and OffscreenCanvas are treated as optional enhancements where a fallback exists. Browser support can differ by operating system.
