The Best Free 60 FPS Converters Online, Compared (2026)
We tested the online tools that convert video to 60 FPS — which ones do real AI frame interpolation, which just relabel the frame rate, and what each actually costs.
First, the trap: two very different kinds of “60 FPS converter”
Half the tools ranking for “60fps converter” don’t create any new frames. They remux or duplicate — the container says 60 fps, but every second frame is a copy of the one before it. Your video looks exactly as choppy as before; only the metadata changed.
The other kind does AI frame interpolation: a neural network looks at two neighbouring frames, estimates the motion between them, and synthesises genuinely new in-between frames. That’s what produces the smooth, high-refresh look people are actually searching for.
When you compare tools, that’s the first question to ask: does it generate new frames, or just relabel the stream?
The contenders
NextbConvert / Videobolt / Screensnap-style FPS changers
These are quick, free, browser-friendly — and most of their modes are frame-rate changers, not interpolators. They’re the right tool if you need to conform a 25 fps clip to a 30 fps timeline (editing compatibility), and the wrong tool if you want choppy footage to become smooth. Some offer a motion-interpolation mode, but it’s typically classical motion-blend (ghosting on fast movement) rather than a neural model.
Good for: conforming frame rates for editing. Not for: actually smoother video.
TensorPix
TensorPix does real AI interpolation and generally produces good results. The catch is the model: it’s subscription-first, with tight limits on the free tier (a few short clips, queue priority for payers). If you convert video regularly and want a batteries-included suite around it, it’s a reasonable paid option.
Good for: heavy users happy to subscribe. Watch for: free-tier limits, upload queue times.
Topaz Video AI
The desktop heavyweight. Topaz’s interpolation (and upscaling) quality is excellent, but it’s a paid desktop application with a serious price tag and serious hardware requirements — you’re renting your own GPU time, effectively. Overkill if you have one clip; the right call for professional restoration work.
Good for: pros with GPUs and budgets. Not for: one-off conversions in a browser.
EditClips 60 FPS Converter
Our 60 FPS converter runs real neural frame interpolation (the RIFE family of models) on our own GPUs — you upload a clip, the AI generates the true in-between frames, and you get a side-by-side preview comparing the original and the 60 fps result before you decide anything. Trying it is free; you only pay (a few credits) if you want the full-quality file, and there’s no subscription required for that.
There’s also a dedicated AI Slow Motion tool built on the same interpolation engine — instead of raising the frame rate, it stretches time up to 4× while keeping motion perfectly smooth, which is how you get the cinematic slow-mo look from normal footage.
Good for: one-click real interpolation in the browser, honest before/after preview, pay-per-file instead of a subscription. Not for: hour-long footage — clips process in minutes, but very long videos are better handled in batches.
Quick comparison
| Tool | Real AI interpolation | Runs in browser | Free to try | Pricing model |
|---|---|---|---|---|
| FPS changers (NextbConvert etc.) | No (relabel/duplicate) | Yes | Yes | Free / ads |
| TensorPix | Yes | Yes | Limited | Subscription |
| Topaz Video AI | Yes | No (desktop) | Trial | One-time, expensive |
| EditClips | Yes (RIFE) | Yes | Yes, with preview | Per-file credits or plan |
How to actually convert a video to 60 FPS
- Open the 60 FPS Converter.
- Upload your clip (drag and drop — up to 10 GB depending on plan).
- Pick the target frame rate — 60 fps for the smooth look, or 120/240 for slow-motion workflows.
- Compare the side-by-side preview. If the motion looks right, download.

When 60 FPS is the wrong goal
Honest note: interpolation shines on gameplay, sports, drone shots, and animation. It struggles with heavy motion blur, very low-light noise, and footage with hard cuts every second (each cut is a motion discontinuity). And film content at 24 fps often should stay 24 fps — the “soap opera effect” is a real aesthetic complaint. Convert because your footage stutters, not because a bigger number sounds better.
