- How do I change a video's FPS?
- Drop the video into the FPS changer, pick the target frame rate (say 30 FPS), and click Process. The converter re-times the frames to hit the exact target — duplicating frames when going up, dropping frames when going down — while duration and audio stay untouched. It runs in your browser, so nothing uploads and short clips finish in seconds.
- How do I convert 60fps to 30fps?
- Select 30 FPS as the target and process — the changer keeps every second frame, which halves the data the encoder has to store. The video looks essentially identical for normal content (30fps is the web standard), and the file gets noticeably smaller. The same applies for 120fps to 60fps: every second frame is kept.
- Does changing FPS change the video speed or length?
- No. An FPS change re-times how many frames are shown per second but keeps total duration and audio exactly the same — a 60-second clip stays 60 seconds. If you want the video to actually play faster or slower, use the video speed changer instead.
- Can this tool increase FPS to 60?
- It can set 60 FPS, but a plain FPS change duplicates existing frames — the motion won't look smoother, just re-timed. To genuinely increase smoothness, use our AI 60 FPS converter, which uses AI frame interpolation to paint brand-new in-between frames so motion actually becomes fluid.
- Does lowering FPS reduce file size?
- Yes, substantially — frames are most of a video's data. Going from 60fps to 30fps roughly halves the frame count, which typically cuts file size by 30-45% at the same quality settings. For maximum size reduction, combine a lower frame rate with our video compressor.
- What frame rate should I use?
- 24 FPS for a cinematic film look, 25/50 FPS for European (PAL) broadcast, 30 FPS for web, social media, and general use, 60 FPS for smooth gaming clips and sports. Screen recordings can drop to 15 FPS to save space. When in doubt, 30 FPS is the safest all-round choice.
- Can this fix variable frame rate (VFR) videos?
- Yes — phone recordings and screen captures often use variable frame rate, which makes editors stutter or drift out of sync. Converting to a constant rate (30 or 60 FPS) with this tool produces a constant-frame-rate file that behaves correctly in Premiere, DaVinci, CapCut, and every other editor.
- Is this FPS converter really free?
- Yes — the conversion runs in your browser via FFmpeg WebAssembly, so we have no server costs to pass on. No watermark, no sign-up, no trial limits. Your video never leaves your device, which also makes it private by construction.
