Drop your files here
Video, audio, images and documents: MP4, MP3, HEIC, DOCX, PDF and 33 more formats. Several files or a link at once.
Why convert
WebM — an open format for video in the browser, common for clips saved from websites. AVI — an old Windows format, found in camera footage and films from the 2000s. Use it when a program or device asks for AVI specifically.
What changes in the file
The video is re-encoded; at High quality the difference is not visible. One video and one audio track are carried over; subtitles and chapters are not. AVI uses an old codec, so at the same quality the file is larger than MP4.
Which settings to pick
If the file has to fit a limit, set File size: the quality is chosen for you. For messengers choose Smaller file and 720p; for editing keep High and the original height.
