Video Converter
Browser-based video converter for MP4, WebM, or GIF. Tune CRF, resolution, and FPS, mute audio, and download without sending frames to a server.
Drop a video or click to browse
Converts locally to MP4, WEBM, or GIF. Great for decks, social, and previews.
Output format
H.264 MP4 for universal playback, VP9 WEBM for lean embeds, or GIF for quick loops.
Try 23 for balanced output. Increase the number to shrink file size.
Output tuning
Use 24–30 fps for most exports. Higher FPS smooths motion but increases file size.
- Pitch decks: MP4, 720p, CRF 23–25, mute if narration is not needed.
- Landing pages: WEBM, 720p, CRF 30–32, 24 fps to shrink weight.
- Looping previews: GIF, 480p, 10–14 fps to keep size in check.
Built for browser-native conversions
The converter ships a WebAssembly video engine, so you can compress or re-encode assets for decks, social, or clients without uploading source footage. The engine downloads once and stays cached in this tab.
- Pick MP4/H.264, WEBM/VP9, or GIF loops with one click.
- Control CRF, resolution, and frame rate to hit a target size.
- Mute or keep audio, optimize for decks, landing pages, or previews.
- All processing stays local—ideal for sensitive or client material.
Need audio-only exports? Use the Audio Converter for MP3, WAV, FLAC, or OGG.
Practical presets that work
- Pitch decks: MP4, 720p, CRF 23–25, mute if narration is not needed.
- Landing pages: WEBM, 720p, CRF 30–32, 24 fps for lighter hero loops.
- GIF previews: 480p, 10–14 fps to keep loops small but readable.
- Retain detail: keep 1080p and lower CRF (18–22) for portfolio reels.
Try preloading the engine before a batch of conversions—the warm cache keeps turnaround quick even offline.
Frequently asked questions
Are my videos uploaded anywhere?
No. The conversion engine runs as WebAssembly inside your browser, so your videos stay on your device.
Which formats can I export?
MP4 (H.264 + AAC), WEBM (VP9 + Opus), and GIF loops. More containers come later as the WASM build grows.
Can I adjust quality and size?
Yes. Tweak CRF, resolution, frame rate, and muting to hit the size you need without leaving the page.
Does it work offline after loading?
Once the engine is cached (about 30MB the first time), conversions run offline in this tab.
