[2025 List] Top 5 Video FPS Increaser Online & Free to Make Your Footage Smooth
In the world of video, frame rate, the so-called FPS, is a key factor when it comes to smoothness and visual fluidity. A higher FPS means more frames per second, resulting in smooth and fluent motion that’s comfortable to watch. With this said, increasing your video’s FPS can make a better watching experience.
While professional software offers complex operations, many users often look for free online tools to get easy and fast help without downloading anything. But are these online increasers truly effective, and how do you pick the right one?
Today, we’ll explore everything about the world of video FPS increasers free online. We’re going to review some popular free options, highlight their pros and cons, and finally, show you why a dedicated AI solution like VidHex Frame Interpolation is the ultimate game-changer for achieving high-FPS video.

Part 1. How to Choose a Great Free & Online Video FPS Increaser?
Not all online tools are created equal, especially when they handle some complex tasks like frame rate conversion. When you’re searching for the right online FPS booster, keep these key factors in mind.
Interface: an intuitive and easy-to-use interface design can make your frame rate conversion easier, especially for beginners.
Format compatibility: does the converter support the input format of your video (e.g., MP4, MOV, AVI, WMV) and the same on output formats? The wider the compatibility, the more versatile the tool.
Output quality: this is the most important factor. Many free online tools use basic frame duplication or simple interpolation algorithms (like bilinear or bicubic). This just simply increases the frame count; it doesn’t create truly new frames, indeed.
Converting speed: online FPS enhancement relies on server power and your internet connection. To handle this intensive task, free online tools can sometimes be very slow, especially for longer or higher-resolution videos.
In addition, you should also note factors like file size limitations, watermark/ads, private security, etc.

Part 2. 5 Best Video FPS Increaser Online & Free in 2025
1. Ezgif.com
Ezgif is primarily known for its comprehensive GIF and video editing tools. Thus, it can also change the frame rate of your footage. While it doesn’t explicitly market itself as an “online FPS increaser” for smooth motion, its video-to-GIF converter allows frame rate adjustments.
Pros
- Offers relatively comprehensive editing features for GIF files and video footage.
- No other software or external devices involved.
- A simple interface design to easily find the target tool for use.
Cons
- It just copies the neighboring frame to add FPS, which is not a natural & continuous frame.

- It has a 200MB file size limitation for uploading.
2. Online-convert.com
Online Converter is a widely compatible online file converter that includes video conversion with editing options for changing frame rate. It’s a general-purpose tool rather than a specialized FPS enhancer. You can choose a detailed video format like MP4 to start editing.
Pros
- A comprehensive online converter that supports files in audio, video, image, text, PDF, etc.
- Support changing the frame rate to up to 120 per second for videos in MP4, AVI, etc.
- Offer other video editing features like changing screen size, changing video bitrate, resizing, handling, etc., before exporting.
