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. ## Specifications | Property | Value | | --- | --- | | 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 | ## How to use Video Converter 1. **Load your video** — Select a video file in Video Converter. Conversion happens in your browser using WebAssembly, so even large files never get uploaded anywhere. 2. **Pick format and quality** — Choose the output format, resolution and bitrate — or start from a ready-made preset if you are not sure what to pick. 3. **Convert and save** — 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. ## Use cases - Getting a clip under the size limit for WhatsApp, Gmail, Discord or a course upload - Converting a recording to a format a specific player, editor or platform accepts - Editors who want a quick change without opening a full desktop suite - Handling confidential footage that must not be uploaded to an online converter ## Tips - 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 - **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. ## FAQ ### 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. ## Related tools - [Video Compressor](https://farvixo.com/tools/video/video-compressor): Shrink videos to a target file size — hit 16 MB for WhatsApp or 25 MB for email with two-pass encoding, live size prediction and no visible quality loss, 100% private in your browser - [Video Trimmer](https://farvixo.com/tools/video/video-trimmer): Cut and trim video clips precisely - [Video Merger](https://farvixo.com/tools/video/video-merger): Join multiple videos into one file - [Video Splitter](https://farvixo.com/tools/video/video-splitter): Split a video into equal parts - [Video Watermark](https://farvixo.com/tools/video/video-watermark): Add text watermarks to videos - [Video to GIF](https://farvixo.com/tools/video/video-to-gif): Turn video clips into animated GIFs --- > Machine-readable index: [llms.txt](https://farvixo.com/llms.txt) · full corpus: [llms-full.txt](https://farvixo.com/llms-full.txt) · agent skill: [skill.md](https://farvixo.com/skill.md).
