FPS Converter
Change any video's frame rate online: 24fps, 25fps, 30fps, 50fps, 60fps, 120fps, or 240fps — convert between any pair. AI-powered when going UP (frame interpolation) for smooth motion, fast FFmpeg processing when going DOWN. Browser-side for short clips, GPU server for longer.

Frequently Asked Questions
- Can I convert 60fps to 30fps?
- Yes — frame rate downconversion is fast and lossless. FFmpeg drops every other frame cleanly. Use this for compatibility with platforms that don't accept 60fps uploads, or to shrink file size.
- What's the difference between upscaling and downscaling fps?
- Upscaling (low to high, e.g. 30→60) requires generating new frames — that's where AI interpolation matters. Downscaling (high to low, e.g. 60→30) drops frames — fast and clean either way. The tool picks the right engine automatically.
- Will frame rate conversion change my video's playback length?
- No — duration stays the same. We're changing how many frames per second, not how many seconds total. To change duration (slow motion or fast motion), use the change-video-speed tool instead.
- What's the best target FPS for YouTube?
- YouTube accepts up to 60fps for smooth playback (and now 4K-120fps on some videos). For most uploads, 30fps is fine; 60fps if you want smooth gaming/sports footage. 120+ is mostly useful as a slow-motion source rather than direct upload.
