Convert & fix videos in your browser securely.
Convert video to audio, compress formats, or attempt to fix corrupted video files. Processing happens securely in your own browser.

Instantly swap containers. No quality loss, but formats must be compatible.
Attempt to salvage readable media and fix timestamps. Max 1GB. Missing moov atoms require desktop recovery; no reference upload is used here.
KuchhBhi.in brings you a revolutionized media converter that does not upload your private family videos or sensitive audio to a random server. Powered by WebAssembly (WASM), our Media Converter & Repair Tool uses your device hardware to transcode files securely.
Basic Repair attempts to remux media that FFmpeg can still read, skip damaged packets, and regenerate missing timestamps. It cannot restore an empty file or rebuild a missing MP4/MOV index (moov atom). Always keep your original recording; recovery is not guaranteed.
Note: If you receive a "moov atom not found" error, the file is too severely corrupted for browser-based repair. You will need a desktop tool like "untrunc" and a healthy reference video.
Easily convert podcast videos, music clips, or lectures from MP4 or WEBM directly into high-quality MP3 or WAV audio formats without leaving this page.
Since this runs locally, converting large videos (e.g., a 1GB movie) will drain your battery and may crash mobile browsers due to limited RAM. Conversions are limited to 100MB; Basic Repair accepts up to 1GB. These limits are not a guarantee that your device has enough memory. Use a desktop recovery tool for missing moov atoms or larger files.
Convert your video and audio files (MP4, WEBM, MP3, WAV, GIF) without uploading them to any server. Our WebAssembly powered engine processes the media locally on your device for 100% privacy. Basic Repair attempts to salvage readable media and regenerate timestamps; missing moov atoms require a dedicated desktop recovery tool.
Quickly extract high-quality MP3/WAV audio from your video recordings.
Attempt to salvage media that FFmpeg can still read. Empty files and missing moov atoms cannot be repaired in this browser tool.
