Every video is a quick run of still pictures. The frame rate, measured in frames per second (fps), says how many of those pictures are shown each second. Sometimes a player, an editor or a platform wants a specific rate, and you need to change video frame rate to match.
This fps converter lets you pick a new rate and save the result. It offers six choices, from 15 to 60 fps, shows the rate your video has now, and warns you when a change will not help. It runs in your browser, so nothing is uploaded.
Read on to learn what each rate is good for, what really happens when you go up or down, and how to avoid the common mistakes.
How to change the frame rate of a video
This video frame rate converter is simple on purpose. There is one choice to make, and the result is a new MP4.
- Drop a video onto the tool. You can add several and change them all at once.
- Under Frame rate, choose a tile: 15 fps, 24 fps, 25 fps, 30 fps, 50 fps or 60 fps.
- Read the Source and Result lines. They show the rate your video has now and the rate you are about to make.
- Press Change frame rate.
- Save each result, or download a batch together as a zip.
The new file is named after the original with the rate added, such as _24fps, and it is saved as an MP4. The original is never replaced.
What each frames per second setting is good for
Each tile carries a short label to help you choose. Here is what they mean in practice.
| Frame rate | Label on the tile | Typical use |
|---|---|---|
| 15 fps | Smallest file | When size matters more than smooth motion. |
| 24 fps | Film look | A cinematic feel; many editors expect it. |
| 25 fps | European TV | Material made for European television. |
| 30 fps | Web and phones | Everyday web video, social posts and phone clips. |
| 50 fps | European TV, smooth | Smooth motion for European-style broadcast material. |
| 60 fps | Games, screen recordings | Fast action, gameplay and screen captures. |
A quick way to think about it: lower rates give smaller files and a more deliberate look, while higher rates give smoother motion and bigger files. Frames per second is a trade between those two things, and the right answer depends on where the video will be seen.
If you are not sure, use the rate a player or platform asks for. If nobody has asked, keeping the rate your video already has is usually the best choice.
Going up or down: what actually happens to the frames
This is the part most people get wrong, so it is worth a moment. A frame rate change does not invent new motion. It works with the pictures that already exist.
Lowering the rate drops frames
Going from 60 fps to 30 fps removes pictures to fit the new rate. The motion is a little less fluid, but the length is the same. When you reduce video fps like this, the file usually shrinks as well. The estimated size above the Change frame rate button goes down as you pick a lower tile.
If you plan to make a slow mo video from a 60 fps clip, slow it down before you lower the rate. Slow motion needs those extra pictures to stay smooth.
Raising the rate repeats frames
Going from 24 fps to 60 fps repeats pictures so that the count per second matches. It does not make motion smoother or add detail. The tool warns you when you choose a rate above your source. For a 24 fps clip set to 60 fps, the note reads: "Going above the source (24 fps) repeats frames. Motion does not get smoother; use it only where a player or site asks for 60 fps."
So raise the rate only when something requires it, for example an editor timeline or a site that insists on 60 fps.
Similar rates, such as 24 and 25
Small differences, such as 24 to 25 fps, are fine for most uses. The length of the video stays the same, so audio and picture stay in step.
Using an fps converter well
- Check the Source line first. If the rate you want is the one your video already has, there is nothing to do.
- Work from your original, not a copy that has already been converted once.
- To make a file smaller, try a lower rate together with Compress video. The two work well side by side.
- To change how fast the action plays, use Change video speed instead, or go straight to speed up video for a faster clip. A frame rate change does not make anything faster or slower.
- Need another format for the same clip? Use Convert video.
There are also shortcut pages that open this tool with a rate already chosen: Convert video to 24 fps, Convert video to 30 fps and Convert video to 60 fps.
If you need to change video frame rate for a whole folder of clips, add them in one go. The button then reads "Change frame rate of" followed by the number of videos, every file gets the tile you chose, and the results come back together as a zip. That is much quicker than running each clip on its own.
Think of this as a video fps converter that does one job and does it plainly. It does not re-time your footage, add effects or change the picture size. If you need those, the other video tools sit beside it in the video tools list, ready for the next step.
The tool takes many common formats, including MP4, MOV, MKV, WebM, AVI, WMV and MPG, and the result is an MP4.
Free, private and done in your browser
There is no account to make and no watermark on the result. Video tools do not use the free daily limit that covers document conversions. Your video stays on your device, and our servers do no video work. See the privacy page for more.
Most videos have no size limit. Files such as some AVI or WMV videos are handled more slowly, and those can be up to 2 GB. The tool works in current Chrome, Edge and Firefox.
Pick your frame rate and go
To change the fps of a video, choose a tile, check the Source and Result lines, and press Change frame rate. Go down to save space, go up only when something asks for it, and keep the original safe.
This video frame rate converter costs nothing, adds no watermark, and your video never leaves your device. Scroll up to the tool and set the rate you need.
