external connection

The conversion engine and libraries are loaded from this site. Automatic caption models are downloaded from Hugging Face and may remain in your browser cache. The contents of the files selected by the user will not be transferred. Large unzipped results may remain in your device's temporary storage and can be removed by clearing results or deleting browser site data. You can use it as a system font even if there is no font connection.

scope of support

We do not guarantee all file formats or codecs. Check the main screen for supported formats and restrictions. Camera RAW, PSD and DRM protected files are not supported. HEIC/HEIF·AVIF·SVG in the general converter is for input only. A separate SVG tool will also output an SVG copy containing only the elements it supports.
