Free video tools that work with the files you have
Video files are the biggest, most stubborn files most people handle. A phone records in HEVC inside a MOV container, a screen recorder emits MKV, a download arrives as WebM, and the place you need to send it wants MP4. These tools convert between the common containers and codecs without asking you to learn FFmpeg flags.
Because video processing needs more compute than a browser tab can reliably offer, these tools are processed on our servers with FFmpeg. Uploads are limited in size and length, processed in a temporary directory, and deleted automatically after your download window ends — see each tool page for the exact limits.

Convert, compress and turn clips into GIFs
Container, codec, and why the file still will not play
A video file is a container (MP4, MOV, MKV, WebM) wrapped around separate video and audio streams encoded with codecs (H.264, HEVC, VP9, AAC). Compatibility problems are usually about one of those layers, not the extension. MP4 containing H.264 video and AAC audio is the safest combination in the world: phones, browsers, WhatsApp, email clients, TVs and video platforms all play it. MOV is an Apple container that often holds HEVC or ProRes, which Windows and Android devices frequently refuse.
Converting to MP4 re-encodes the streams, which takes time and can lose a little quality unless the bitrate is kept high. Compressing targets a smaller file with a deliberate quality trade-off, and turning a clip into a GIF is the most destructive option: GIF has a 256-colour palette, so use it only for short, simple clips. All three jobs run on our server because encoding is CPU-heavy; the files are temporary and deleted after download.
- A MOV from an iPhone will not open on a PC
- MOV to MP4 converts H.264/HEVC into a broadly compatible MP4; quality stays near the source.
- A clip is too large to send
- Video Compressor with 720p output typically cuts size by 60–80% for screen recordings and talking-head footage.
- A short reaction loop for a chat
- Video to GIF works best under 10 seconds and 480 px wide; anything longer becomes a heavy file.
