Video Frame Rate Converter

Video Frame Rate Converter is a completely free online tool that lets you convert video frame rates (FPS: Frames Per Second) easily and securely in your browser. Frame rate represents the number of frames displayed per second, and it is a crucial parameter that greatly affects the smoothness and visual feel of your video.

For example, movies traditionally use 24fps to create a distinctive cinematic look. TV broadcasts and YouTube videos commonly use 30fps as the standard, while gaming content and sports footage benefit from 60fps for ultra-smooth motion. This tool offers seven target frame rate options — 15fps, 24fps, 25fps (PAL standard), 30fps, 48fps, 50fps, and 60fps — allowing you to convert to the optimal frame rate for your specific purpose.

The tool automatically detects and displays the source video's frame rate, so you can understand the difference before and after conversion. All processing is performed entirely client-side using the browser's Canvas API and MediaRecorder API, meaning your video data is never uploaded to any external server. You can safely convert private footage or business videos with complete confidence. Use it for adjusting FPS for social media uploads, converting to cinematic 24fps, smoothing game recordings, and much more.

Frame Blending for Smoother 30fps to 60fps Conversion

When upconverting from 30fps to 60fps, you can enable the frame interpolation (blend) option. Unlike simple frame duplication, it generates intermediate frames by blending adjacent source frames, making motion look noticeably smoother. While it is not AI-based frame generation, it requires no sign-up and no upload — you can try 60fps conversion instantly, right in your browser.

MP4 Output, Audio Preservation, and Size Estimation

Choose between MP4 (H.264) and WebM output formats (MP4 availability depends on your browser). MP4 is ideal for playback on phones and TVs, while WebM keeps file sizes small. The audio track of the source video is automatically analyzed and carried over to the converted video. An estimated output size is shown before conversion, making it easy to stay within social media upload limits.

Compare Before and After Instantly

When conversion finishes, a comparison preview appears above the download button showing the original and converted video side by side in a single frame. Drag the center bar left and right to reveal the original on the left and the converted result on the right, both playing in sync — so you can check the smoothness of a 60fps conversion before downloading. If you want a different result, use "Change Settings & Reconvert" to pick another FPS, or jump straight to the next file with the "Convert Another Video" button.

When to Use 60fps, 30fps, or 24fps

Converting to 60fps is useful for game recordings, tutorials, sports clips, and videos where smooth motion matters. 30fps is a practical standard for YouTube and social media because it balances smoothness and file size. 24fps works well when you want a cinematic look for short films, product clips, or portfolio videos. If you want a smaller file or a more stylized frame-by-frame feel, lowering the video to 15fps or 24fps can also be a good choice.

If you need to cut only part of a video before or after changing FPS, use [Video Trimmer](/en/movie/video-trimmer/). To turn the converted clip into an animated GIF, use [Video to GIF Converter](/en/movie/video-to-gif/). If the video audio is too quiet after editing, use [Video Volume Booster](/en/movie/video-volume-booster/). These related tools help you finish lightweight video edits in the browser without opening a full editing suite.
