- 15 fps: smaller files for screen recordings and slideshows.
Variable frame rate
Phones and screen recorders often record at a variable frame rate, which makes audio drift in Premiere and other editors. Converting to a constant 30 or 60 fps fixes that.
Good to know
Frames are dropped or duplicated to reach a constant frame rate. This also turns variable-frame-rate phone and screen recordings into constant frame rate, which editors handle better.

Frequently asked questions
Does a higher frame rate make video smoother?
Only if the source had that many frames. Converting 30 fps to 60 fps duplicates frames; it does not invent new motion.
Do I have to pay or sign up to use the Change Video FPS?
No. There is no account, no payment and no watermark. The only limit is 1 GB per file, set by what browsers can handle.
Are my files safe?
Yes. Files are converted locally in your browser and are never uploaded. When you close the page, nothing is left behind.
Does it work on iPhone and Android?
Yes, in Safari, Chrome and other modern mobile browsers. Short files work best on phones; for long or high-resolution videos a computer is faster.
