Common questions
Why does video conversion take longer than images?
Video files contain thousands of frames that each need to be decoded and re-encoded. Even with WebAssembly running at near-native speed, a 50 MB video takes longer than a 50 MB image. The first conversion also downloads the WebAssembly codec (5–20s), but subsequent ones are faster.
What video format should I convert to for social media?
MP4 with H.264 video is the universal choice — accepted by Instagram, TikTok, YouTube, Twitter, LinkedIn, and every other platform. MKV, MOV, and AVI should all be converted to MP4 before uploading.
Can I extract audio from a video file?
Yes. Use the MP4 to MP3 converter — drop any video file (MP4, MOV, MKV, AVI) and it extracts the audio track as MP3. No video processing, just the audio.
