Video Converter
Convert videos to MP4, WebM, MKV, MOV, GIF or extract MP3/AAC — AI analysis, batch queue, social presets, 100% private FFmpeg in your browser
What is Video Converter?
Video Converter is a free browser-based video tool from Farvixo that lets you convert videos to MP4, WebM, MKV, MOV, GIF or extract MP3/AAC — AI analysis, batch queue, social presets, 100% private FFmpeg in your browser. It uses an in-browser FFmpeg build compiled to WebAssembly, so even large clips are processed on your own machine and never uploaded. No account, no watermark and no per-file size limit imposed by a server.
How to use Video Converter
Select a video file in Video Converter. Conversion happens in your browser using WebAssembly, so even large files never get uploaded anywhere.
Choose the output format, resolution and bitrate — or start from a ready-made preset if you are not sure what to pick.
Start the conversion and watch the progress bar; longer clips take a little time because the work runs on your own machine. Download when it finishes.
Frequently Asked Questions
What video formats can I convert?
Input: MP4, MKV, MOV, AVI, WMV, FLV, WebM, MPEG, 3GP, M4V, TS, MTS, GIF and more. Output: MP4 (H.264), WebM (VP9), MKV, MOV, AVI, GIF, or audio-only MP3, AAC, WAV, FLAC, OGG, M4A.
Is my video uploaded to a server?
No. All conversion runs 100% in your browser using FFmpeg WebAssembly. Your videos never leave your device — fully private, no account required.
What is the maximum file size?
Browser FFmpeg works best for files under ~200MB per video. Larger files may work depending on your device RAM. Batch mode processes videos one at a time to manage memory.
Can I convert videos for YouTube, Instagram or TikTok?
Yes! Use Social/Platform Presets for YouTube 1080p, YouTube Shorts, Instagram Reels, TikTok, LinkedIn, X/Twitter, and WhatsApp Status — dimensions, bitrate and format applied automatically.
Can I extract audio from a video?
Yes — set Output type to "Audio only" and choose MP3, AAC, WAV, FLAC, OGG or M4A. Optional loudness normalization included.
Does AI analysis really help?
AI Smart Analysis detects resolution, bitrate, duration, orientation and quality score, then suggests optimal format, resolution and compression mode before you convert.
Can I trim, rotate or change speed?
Yes — use Trim & Edit settings for start/end timestamps, 90° rotation, and speed from 0.5× to 2×. AI denoise, stabilization and upscale filters are also available.
Can I convert multiple videos at once?
Yes — unlimited batch upload with queue manager. Download individually or all results as a ZIP with performance report.
How is this better than CloudConvert or HandBrake?
Farvixo Tools combines HandBrake-level codec control + CloudConvert-level format breadth + unique features: AI analysis, social presets, batch queue, performance report, and 100% private browser processing — no upload wait, no daily limits.

Video Converter at a glance
- Tool
- Video Converter — Video Tools
- Purpose
- Convert videos to MP4, WebM, MKV, MOV, GIF or extract MP3/AAC — AI analysis, batch queue, social presets, 100% private FFmpeg in your browser
- Input
- One or more files (MP4, WebM, MOV, AVI, MKV)
- Output
- Video file in the selected container and codec
- Processing
- In your browser — files are never uploaded to a server
- Price
- Free, unlimited, no account required
- Limitations
- Bounded by your device's memory and CPU rather than a server quota; very large files may be slow on older hardware
Tips for better results
- Processing speed depends on your own CPU, since the work is local. A laptop on battery-saver will be noticeably slower.
- H.264 (MP4) is the safest choice for compatibility; VP9 or AV1 give smaller files but decode slowly on older devices.
- Leave the tab open and visible — a backgrounded tab gets throttled by the browser and the encode will crawl.
Common problems and how to fix them
The encode is very slow
Everything runs on your device rather than a server farm. Pick a lower resolution or a faster preset, keep the tab in the foreground, and close other heavy tabs.
The output has no sound
The chosen container cannot carry the source audio codec — WebM cannot hold AAC, for example. Re-encode the audio instead of copying the stream.
The browser ran out of memory
The clip is too large to hold in memory. Trim it into shorter segments and process them one at a time.
