Yes, and you don't need to pay or put up with a watermark. The catch is that the free, clean option isn't the Photos app. It's iMovie.
The free, watermark-free option: iMovie
iMovie is made by Apple, costs nothing, has no ads, and never adds a watermark.
- Install iMovie from the App Store if you don't have it.
- Tap Start New Project > Movie, pick your video, and tap Create Movie.
- Tap the clip, tap Speed, and drag toward the hare. 2x is the max in one pass.
- Tap Done > Share > Save Video.
Watch out for these with free third-party apps
Many "speed up video" apps in the App Store are free to download but:
- Add a watermark unless you subscribe.
- Show ads between steps.
- Lock export quality (like 720p) behind a paywall.
- Use weekly subscriptions that add up fast.
Before using one, check the App Store listing for "In-App Purchases" and read recent reviews.
What about Photos?
Photos only changes Slo-mo clips, back toward normal speed. It can't make a regular video faster.
What about online tools?
Browser-based editors can speed up video for free too, but you upload your video to someone else's servers, and many have file-size limits or watermarks on free plans. See speed up video online free for what to check.
Faster than 2x for free
Export from iMovie at 2x, start a new project with that export, and speed it up again. Still free, still no watermark. How it works.
Free tool: Speed Up Video makes any video 0.25× to 4× faster or slower in your browser, with natural-sounding audio and no watermark.
