Thirty frames per second (30 fps) is the everyday rate of the web. Most phone clips, social posts and website videos use it, so it is the safest choice when you are not sure what a platform wants. If your footage is at some other rate, you can convert video to 30fps in a few clicks.
This page opens the frame rate tool with the 30 fps tile chosen. Add your video, press Change frame rate, and save the MP4. It runs in your browser and nothing is uploaded.
Here is how it works, what changes when you go from 60 or 24 to 30, and how to keep the file tidy.
How to convert a video to 30 fps
The shortcut opens the tool with 30 fps already selected.
- Drop a video onto the tool. You can add several.
- Look for the Frame rate tile marked 30 fps, with the label Web and phones.
- Check the Source and Result lines to confirm the change.
- Press Change frame rate.
- Save the new file, or download a batch as a zip.
Your result is an MP4 with _30fps added to the original name, and the length stays the same.
You can convert a whole set in one go. Add every file you want, leave the 30 fps tile selected, and press the button once. The tool works through them with the same setting, and you can download the finished videos together as a zip.
Why 30 fps is the standard for web and phone video
At 30 frames per second, each picture stays on screen for a thirtieth of a second. That is quick enough that your eye reads the pictures as smooth, continuous motion, and slow enough that the file stays light. It is a sensible balance, which is why it became the habit for so much video you see every day.
Thirty frames per second looks natural for everyday footage: talking, walking, events and screen demos. It is smooth enough that people rarely notice the rate, and it keeps files lighter than higher rates because there are fewer pictures to store.
There is a practical side too. A set of clips that all share one rate is much easier to work with. If a few of your clips came from a screen recorder at 60 and others from a phone at 30, bringing them all to one rate means they play and edit the same way, with no odd jumps when you put them next to each other.
It is also a safe middle. Many sites and players handle it without fuss, so a 30 fps file tends to play well on whatever your viewer uses. If a site tells you which rate it prefers, follow that, but 30 is a sound default.
| Use | Why 30 fps works |
|---|---|
| Website and blog video | Common, light and plays everywhere. |
| Social posts | A familiar, smooth look for everyday clips. |
| Phone footage | It is the rate many phones record at. |
| Screen demos | Enough for clicks and typing, with a smaller file. |
Going down to 30 fps from 60, or up from 24
The direction decides what happens to your pictures. The tool never changes the length of the video.
From 60 fps to 30 fps
Half the pictures are dropped. Motion is slightly less fluid, but for most clips the difference is small, and the file usually gets smaller. This is the most common reason to convert to 30 fps: a screen recording or a gameplay clip is too heavy to share.
If you also want a slow mo video, slow the 60 fps file down first. The pictures this step drops are the ones that keep slow motion smooth.
From 24 or 25 fps up to 30 fps
Going up repeats some pictures so the count reaches 30 per second. It does not add smoothness. The tool shows a note when your choice is above the source rate, and the note is a fair reminder: raise the rate only where a site or player asks for 30.
From 29.97 fps to 30 fps
Some cameras record at a rate just under 30. The Source line shows the exact figure. Converting to 30 fps is a tiny change and the length is unaffected.
Keep the file small and the result clean
- Convert from the original file, not a copy that has been through a chat app.
- If the video is still large afterwards, follow with Compress video or Compress video for WhatsApp.
- Cut off what you do not need with Trim video before converting. If the whole clip is simply too slow, use speed up video instead.
- To change the picture size too, use Resize video.
Because 30 fps is so widely used, converting to it is often a way of fixing a compatibility problem rather than improving the look. If a clip stutters in one player or refuses to import into another, matching the common rate is a quick and harmless thing to try before anything more drastic.
Remember that the frame rate for web video is only one part of how a clip behaves online. The picture size and the file size matter just as much for how fast it loads. A 30 fps video that is also compressed and sized sensibly will load quickly and look fine, so treat the three together.
If you want to lower frame rate for social media because a post is slow to upload, converting to 30 fps is a sensible first move, and then compressing the result handles the rest. To convert video to 30fps and then shrink it, run the tool twice. Neither step touches your original, so you can try both and keep whichever result you prefer.
Other rates are a click away. See the main Change video frame rate page, or the shortcuts for 24 fps and 60 fps.
Free, private and no account
The tool is free to use, with no sign-up and no watermark. Video tools are not counted in the free daily limit for document conversions. Your video never leaves your computer; see the privacy page.
Most videos have no size limit. A few files, such as certain AVI or WMV videos, take longer and can be up to 2 GB. It works in current Chrome, Edge and Firefox.
Set your video to 30 fps
To convert video to 30fps, drop in your file, confirm the 30 fps tile and press Change frame rate. Check the Source line first, and keep your original.
It costs nothing and your video stays on your device. Scroll up to the tool and make the change.
