If you have looked for a blur tool in the iPhone Photos app, you have not missed it: there is not one for video. Photos can trim, crop, rotate and add filters to a clip, but it cannot blur or pixelate part of it.

The quickest free option is Safari. This page has a video blur tool built in. It runs on your iPhone, so the video is not uploaded, and there is no app to install or account to create.

How to blur a video on iPhone in Safari

Open the video

On this page in Safari, tap Choose video, then pick Photo Library, or Choose File for a video saved in Files.
Choose what to blur

Tap Blur. Leave Whole video selected to blur everything, or tap Chosen areas and then Find faces automatically. To blur something else, drag a box over it with your finger.
Set the strength and export

Move the Blur amount slider until the area is unrecognizable, then tap Export video. Keep Safari open on this page while it exports.
Save it to Photos

Tap Share or save to Photos, then Save Video. If you tapped Download video instead, open the file in the Files app (in Downloads), tap Share, then Save Video.

Blur a face on an iPhone video

Tap Chosen areas, then Find faces automatically. The face detector downloads once (about 3 MB), scans the video on your iPhone, and puts a moving oval over each face. Small, distant or turned-away faces can be missed, so scrub through the video and drag a new area over any face it skipped.

To keep one person visible, tap their face area and tap Delete. If a face you added by hand moves, tap Track movement automatically and the area follows it. There is more detail in the guide to blurring faces in a video.

Pixelate a video on iPhone

Prefer the mosaic look? Tap Pixelate instead of Blur. For anything private, such as an address, an ID or a license plate, tap Black box, which covers the area in solid black.

Tips for iPhone videos

Trim first. Tap the scissors under the preview to keep only the part you need; shorter clips export faster.
Long and 4K clips take a while on a phone. If you have a Mac or PC nearby, AirDrop the video over and use the same page there.
The sound is kept unless you turn off Keep sound under Export settings.
The video is saved as MP4, which plays in Photos and uploads anywhere.

Questions about this kind of blur

Can you blur a video in the iPhone Photos app?

No. Photos can trim, crop, rotate and filter a video, but it has no blur or pixelate tool. Use a browser tool like this one or a third-party editing app.

Is there a free way to blur a video on iPhone without an app?

Yes. Open this page in Safari, choose the video, blur it and save it to Photos. It is free, with no watermark and no signup.

Where does the blurred video go?

If you tap Share or save to Photos and then Save Video, it goes straight to your Photos library. If you tap Download video, it is saved to the Downloads folder in the Files app.

Is my video uploaded?

No. Everything, including face finding, runs on your iPhone, and the video never leaves it.

Why is exporting slow on my iPhone?

The whole video is re-encoded on your phone, so long or 4K clips take longer. Trimming the clip, or choosing a smaller size under Export settings, speeds it up.
