Frequently Asked Questions
Everything you need to know about browser-based video conversion.
Why convert to MP4 format?
MP4 with H.264 encoding is the worldwide gold standard for digital video. It plays natively on virtually all computers, iPhones, Android devices, TVs, and websites without requiring third-party codecs or player installations.
Does converting to MP4 work in Windows Media Player?
Yes! FileFryer packages converted MP4 videos with fast-start metadata headers (moov atom at the front of the file) and 1-second keyframe intervals. The exported video shows its full duration and seeks smoothly forward and backward in Windows Media Player.
Can I downscale a video to save disk space?
Yes. You can select 720p or 480p from the resolution presets to convert high-bitrate phone or camera recordings into compact files ready for email, chat, or school submissions.
Are my video clips uploaded anywhere?
No. All video rendering, scaling, and re-encoding occurs 100% inside your local web browser sandbox using hardware-accelerated WebCodecs and canvas APIs. Not a single frame ever leaves your device.
Can I convert video clips into animated GIFs?
Yes! Select the GIF export preset to transform any short video clip into a looping animated GIF suitable for documentation, Slack, Discord, and GitHub issues.
Can I mute or strip the audio track during conversion?
Yes. You can toggle the audio mute option to remove voice, music, or background noise, producing a clean, video-only export with significantly reduced file size.
