FPS Comparison Table with Size Estimates
See the estimated file size at every frame rate step (60 → 30 → 24 → 15 → 10 fps) before you process — so you can pick the right balance of size and smoothness for your use case.
Common Use Cases for Video Frame Rate Reducer
Screen Recording Compression
Screen recordings of slides, tutorials, and UI walkthroughs rarely need more than 15–24 fps. Reducing a 60 fps screen recording to 24 fps cuts file size by up to 50% with no visible quality loss for non-motion content.
Social Media & Messaging Uploads
Reduce video frame rate to 30 fps before uploading to WhatsApp, Instagram, and TikTok — these platforms re-encode to 30 fps anyway, so reducing first prevents double-compression quality loss.
Email & File Sharing Attachments
Reduce a 60 fps video to 24 fps to cut file size by ~40% before attaching to email. Combined with bitrate reduction, this is the fastest way to get a video under Gmail's 25 MB attachment limit.
Discord, Slack & Team Messaging
Reduce video frame rate to 24 fps to shrink files for Discord (8 MB free tier) and Slack (50 MB) uploads. Most team communication videos — demos, bug reports, walkthroughs — look identical at 24 fps.
LMS & E-Learning Video Submissions
Reduce lecture recordings and tutorial videos to 24 fps for LMS uploads on Moodle, Canvas, and Blackboard. Lecture content at 24 fps is indistinguishable from 60 fps and uploads significantly faster.
Web Video Optimization
Reduce video frame rate to 24 or 30 fps for web embedding to reduce bandwidth costs and improve page load times. Web video at 24 fps is the standard for background videos and hero sections.
Understanding Video Frame Rate Reduction
What is Video Frame Rate?
Frame rate (measured in fps — frames per second) is the number of individual images displayed per second of video. Common frame rates are 24 fps (cinematic standard), 30 fps (broadcast and web standard), and 60 fps (gaming, sports, and high-motion content). Higher frame rates produce smoother motion but require significantly more data — a 60 fps video contains twice as many frames as a 30 fps video of the same duration, making it roughly 40–50% larger. Our video frame rate reduceruses the browser's Canvas API and MediaRecorder API to re-encode your video at a lower frame rate entirely locally — no server upload required.
How Our Video Frame Rate Reducer Works
- 1Upload your video:Drag and drop any video file (MP4, WebM, MOV, AVI, MKV) onto the drop zone. The file is loaded into the browser's video decoder — no data is sent to any server. The FPS comparison table shows estimated sizes at each target frame rate.
- 2Select target frame rate and settings: Click a row in the comparison table or use the dropdown to choose your target fps (60 → 30 → 24 → 15 → 10). Set the video bitrate and optionally remove the audio track for maximum compression.
- 3Download the reduced video: The video is re-encoded in real-time using
canvas.captureStream(fps)and downloads automatically when complete. The results panel shows original size, reduced size, and reduction percentage.
What Gets Reduced
- Frame Count: Reducing from 60 fps to 30 fps halves the number of frames in the video, which is the primary driver of file size reduction. The encoder also benefits from better inter-frame prediction with fewer frames to process.
- Temporal Data: Lower frame rates mean less motion data per second, which allows the video encoder to use larger GOP (Group of Pictures) sizes and more aggressive inter-frame compression — amplifying the size reduction beyond the raw frame count ratio.
- Bitrate Efficiency: At lower frame rates, the same bitrate budget is spread across fewer frames, meaning each frame gets more bits and higher quality — or you can reduce the bitrate proportionally for even smaller files.
- Audio Track (optional): Optionally remove the audio track entirely for screen recordings or silent clips — this can reduce file size by an additional 10–20%.
Important Limitations
The video frame rate reducer uses the browser's native MediaRecorder API, which processes video in real-time — a 5-minute video takes approximately 5 minutes to process. Keep the browser tab active during processing. The browser cannot reliably detect the source frame rate from the video metadata — if the FPS comparison table shows incorrect estimates, manually set the source frame rate using the dropdown. Chrome and Edge produce the best results; Firefox typically outputs WebM regardless of the source format.

Frequently Asked Questions About Video Frame Rate Reducer
A video frame rate reducer is a tool that re-encodes a video at a lower fps (frames per second) to reduce its file size. Our free video frame rate reducer online works entirely in your browser using the Canvas and MediaRecorder APIs — your video is never uploaded to any server.
Reducing from 60 fps to 30 fps typically achieves 30–50% file size reduction. Reducing from 60 fps to 24 fps typically achieves 40–55% reduction. The exact savings depend on the video content — high-motion content (sports, gaming) compresses less than low-motion content (screencasts, presentations). The FPS comparison table shows estimated sizes before you process.
For most content, reducing to 30 fps is completely imperceptible. Reducing to 24 fps gives a cinematic look that is standard for films and TV. Reducing to 15 fps is noticeable for fast-motion content but perfectly acceptable for screencasts, slide recordings, and tutorials. Reducing below 15 fps will produce visible choppiness for most content.
Absolutely. Our video frame rate reducer processes everything locally in your browser using the Canvas and MediaRecorder APIs. Your video is never uploaded to any server, never stored, and never leaves your device. All processing happens entirely on your machine.
Yes — 100% free, forever. No signup, no account, no premium tier, no file size limits, and no ads interrupting your workflow. Just upload your video, reduce the frame rate, and download.
Browser APIs do not expose the source frame rate from video metadata before playback begins. The tool defaults to 30 fps as the most common value. If your video is 60 fps (gaming, iPhone slow-motion) or 25 fps (PAL broadcast), manually set the source frame rate using the dropdown to get accurate size estimates.
The video frame rate reducer outputs MP4 (H.264) on Chrome and Edge, or WebM (VP9) on Firefox. MP4 is the most compatible format for sharing across devices and platforms. The output format is determined by your browser's MediaRecorder support.
The video frame rate reducer uses the browser's MediaRecorder API, which processes video in real-time — it plays the video through a Canvas element at the target frame rate and records the output. A 5-minute video takes approximately 5 minutes to process. Keep the browser tab active during processing.
Since processing runs entirely in your browser, the practical limit depends on your device's available RAM. Most modern devices handle videos up to 1 GB without issues. For very long recordings (over 30 minutes), ensure your device has sufficient RAM available.
