A video converter changes the container and codec of a video file by decoding the source stream and re-encoding it into the target format. The transformation happens server-side with ffmpeg entirely in memory: the upload is never written to disk and nothing is left after the response is sent. MP4, MOV, WebM and GIF are accepted as both input and output, giving twelve conversion pairs in total.
What a Video Converter Actually Does
A video file is two things at once: a container and the codecs inside it. The container (MP4, MOV, WebM) is the wrapper that holds the video track, the audio track, and the timing information that keeps them in sync. The codec (H.264, VP9, AAC, Opus) is the compression scheme that decides how the actual frames and samples are stored. A video converter decodes the source streams and hands them to a different encoder, then muxes the result into the new container.
This is why converting is not the same as renaming a file extension. Changing .webm to .mp4 in Finder produces a file that most players refuse to open, because the bytes inside are still VP9 and Opus in a WebM wrapper. Real conversion re-encodes those streams into what the target container expects.
Why You Convert Between Video Formats
- Universal playback: MP4 with H.264 is the closest thing to a format every device plays without argument - phones, TVs, browsers, editing software. When something refuses to open a clip, converting to MP4 is the standard first fix.
- Web delivery: WebM with VP9 is built for the web and typically produces smaller files than H.264 at comparable quality, which matters for a video that autoplays in a page hero.
- Apple and editing workflows: MOV is QuickTime's container and the format Final Cut and older Apple tools expect natively.
- Silent looping clips: GIF plays anywhere without a video player and loops by default, which is why it survives for reaction clips, product demos and documentation. It has no audio and a 256-colour palette per frame, so it is a deliberate trade rather than an upgrade.
- Shrinking a GIF: converting an animated GIF to MP4 or WebM usually cuts the file size dramatically. A multi-megabyte GIF often becomes a few hundred kilobytes as MP4 with no visible quality loss.
How This Video Converter Works
Drop a single video onto the upload card or click to browse. Pick a target format from the dropdown - MP4 is the default - and start the conversion. The file streams to a processing endpoint, ffmpeg decodes and re-encodes it, and a progress bar tracks the job from 0 to 100 percent while it runs. Longer clips take longer; the progress figure is read from ffmpeg's own reporting rather than estimated.
Files up to 100 MB are accepted, one at a time. Anything larger is rejected at the upload step before any encoding work starts, so no time is spent on a file that will not finish. When the job completes the result plays inline - GIF output renders as an image, everything else in a video player - with a download button beside it.
Encoding Settings
- MP4 and MOV: H.264 video with AAC audio, written with fragmented-MP4 flags so the file is playable as it streams rather than needing the index at the end.
- WebM: VP9 video with Opus audio, encoded in constant-quality mode rather than at a fixed bitrate.
- GIF: a two-pass palette process. The first pass analyses the clip to build an optimised 256-colour palette, the second maps frames onto it with dithering. Output runs at 15 frames per second and is scaled to 480 pixels wide, which keeps the file manageable.
Format Reference
A quick guide to picking the right output target:
- MP4: the default choice. H.264 plus AAC plays on effectively every device and platform in use today. Pick this unless you have a specific reason not to.
- WebM: web-first delivery. Smaller than MP4 at similar quality and well supported in modern browsers, though not by older Apple devices.
- MOV: Apple and editing pipelines. Same H.264 and AAC as the MP4 output, in QuickTime's container.
- GIF: short silent loops that need to play as an image. No audio, 256 colours per frame, and much larger than a real video of the same clip. Use it for compatibility, not quality.
Other video tools that pair with conversion: trimming a clip down to the part you need before converting, resizing to a smaller resolution, extracting the audio track as MP3 or FLAC, and removing the sound entirely.
FAQ
Some, yes. Every format here is lossy, so re-encoding always discards a little detail. The settings are chosen to make that difference hard to see at normal viewing size. The exception is GIF, which is limited to 256 colours per frame and drops to 15 frames per second, so converting to GIF is a visible quality trade in exchange for compatibility. Avoid converting the same clip back and forth repeatedly, since each pass compounds the loss.
Upload the GIF, pick MP4 as the target, and convert. The usual reason is file size: GIF is an inefficient way to store motion, and the same animation as MP4 is often a fraction of the size with no visible difference. A multi-megabyte GIF frequently comes out as a few hundred kilobytes. The trade-off is that MP4 needs a video player, while GIF plays anywhere an image does.
It is discarded. GIF is an image format with no audio track at all, so converting any video to GIF produces a silent result. If you want to keep the sound, convert to MP4, MOV or WebM instead. If you want the audio on its own, the extract audio tool saves the soundtrack as MP3, AAC, FLAC or WAV.
MP4 unless you have a reason not to. It uses H.264 and AAC, which play on effectively every phone, browser, TV and editing program in use. WebM is smaller at similar quality and good for web embedding, but is not supported on older Apple devices. MOV suits Apple editing workflows. GIF is only worth choosing when the clip has to play as an image rather than in a video player.
No. The file extension only labels the container; it does not change the codecs inside. A renamed WebM still holds VP9 video and Opus audio, which most players cannot read from an MP4 wrapper, so the file will usually fail to open or play without sound. Real conversion decodes those streams and re-encodes them into what MP4 expects.
100 MB per video, one file at a time. Larger files are rejected at the upload step before any processing starts, so you do not wait on a job that cannot complete. For a long clip that exceeds the limit, trimming it down to the section you actually need first will often bring it under.
The video is sent to the server for processing, because re-encoding needs ffmpeg, but it is never written to disk. The file is held in memory for the duration of the conversion, the result is returned to your browser, and the buffer is released when the request finishes. Nothing is stored, logged or cached.
It depends on the length, resolution and target format. Short clips finish in seconds. GIF output is the slowest, because it runs a two-pass palette process to pick the best 256 colours for the clip. The progress bar reflects ffmpeg's actual reported position rather than an estimate, so it is a real measure of how far along the job is.
Free with no registration. No watermarks are added to the output, and no features are held back behind a paid tier. The same applies to the other video tools, including trimming, resizing, audio extraction and muting.
