Since conversions run in your browser, the limit depends on your device's available memory. We recommend files under 500MB for best results. Very large files may cause the browser to run out of memory.
We support all modern browsers including Chrome, Firefox, Edge, and Safari. For best performance, we recommend using the latest version of Chrome or Edge.
Yes, the converter works on mobile browsers. However, due to mobile memory limitations, large file conversions may not work as well as on desktop.
Common reasons include: the file is too large for browser memory, the file format is corrupted, or the browser tab was inactive. Try with a smaller file or refresh the page and try again.
