Video Converter Online - Convert Videos to Different Formats
Need a video in a different format? The Video Converter by Trencada converts your videos to WebM, MP4, or an animated GIF — right in your browser. Upload an MP4, MOV, or WebM file, pick your output format, resolution, and quality, then download the result. 100% client-side: your video is never uploaded to a server, and Trencada never stores it. No signup, no watermarks, free to use.
How to Convert a Video
Four quick steps:
- Upload your video. Drop a video file onto the upload box or click to choose one. Supported inputs include MP4, MOV, and WebM — files under about 300 MB work best.
- Choose your output. Select "Convert to": WebM Video, MP4 Video, or Animated GIF. For video output, set the resolution (Original, Max 1080p, Max 720p, Max 480p, or Max 360p) and quality (High, Medium, Low). For GIF, choose the width (320, 480, or 640 px), frame rate (5–15 fps), and how many seconds to convert (1–20, taken from the start of the video).
- Click "Convert & Download". Your video plays through in real time while the browser re-records it — a progress bar shows the conversion as it happens. Tip: conversion runs in real time, so a 30-second video takes about 30 seconds.
- Preview and download. Watch the result, compare the original and converted file sizes, then click "Download" to save it as your-video-converted.mp4 (or .webm / .gif). Use "Choose another video" to convert another file.

Frequently Asked Questions
What is a video converter?
A video converter changes a video from one file format into another. This can help when a video won't play on a device, is too large to share, or needs a specific format for a website or app.
Which video formats can I convert?
You can convert MP4, MOV, WebM (and M4V, MKV, AVI, OGV) files into WebM, MP4, or an animated GIF. Note: MP4 output depends on your browser's recording support — if your browser can't record MP4 directly (mainly Safari), the tool automatically falls back to WebM.
Can I convert MP4 to another video format?
Yes. Upload the MP4 file and choose WebM, MP4, or Animated GIF as the output format.
Can I convert a video for a specific device?
Yes. Converting a video into a format supported by your target device or application can improve playback compatibility — for example, WebM for the web or MP4 for phones.
Will video quality change after conversion?
It can. Quality depends on the source file and the settings you choose: resolution (Original down to 360p) and quality (High, Medium, Low). Choose Original resolution and High quality to preserve as much detail as possible.
Does video conversion reduce file size?
It can. Lower resolutions and quality settings produce smaller files — the tool shows you the original and converted file sizes side by side so you can compare.
Do I need to install video conversion software?
No. The Video Converter works directly in your web browser, so no additional software is required.
Is the Video Converter free?
Yes. The Video Converter on Trencada is free to use, with no signup and no watermarks.
Is my video uploaded to a server?
No. Conversion runs entirely in your browser — the video plays through once while the browser re-records it locally via canvas and MediaRecorder (or a built-in GIF encoder). Nothing is uploaded anywhere.
How long does conversion take?
Conversion runs in real time: a 30-second video takes roughly 30 seconds to convert, since the browser plays and re-records it. Shorter clips and lower resolutions finish faster.
