Blur faces in group photos
Choose a photo, review the detections, and blur faces you want to hide. Adjust the effect or add boxes, then download a PNG at the original image dimensions.
How to blur faces in a photo
1. Choose one photo. To blur faces, open a JPG, PNG, WebP, HEIC, or HEIF image from your device, or drag it into the tool. No account is needed, and your photo stays on your device. Use the photo you intend to share so you can check everyone in the final image.
2. Wait for detection. To blur faces across a group photo, the tool first finds likely faces and adds covers to them. The first run also loads the detection files. Keep the page open until the progress indicator finishes; large photos and slower devices can take longer.
3. Review every person. When you blur faces, check the background as well as the main subjects. Small faces, profiles, and partly hidden faces can be missed. Choose Add a box and drag over any missed face. If a box covers something that is not a face, select it and remove it.
4. Adjust the effect. You can blur faces with Blur, pixelate them with Mosaic, or hide them with Solid cover. Adjust strength and extra coverage, then move or resize individual boxes. To keep someone visible, open the face-box list and turn off that person’s box while leaving the other covers enabled.
5. Download the finished image. After you blur faces, check the result and save a PNG at the original image dimensions. Editing outlines are left out of the download. Open the saved file before posting it, especially when the photo contains a large group or people close to the edge of the frame.
Automatically blur faces, then fine-tune each box
You can blur faces across a crowded photo without drawing a rectangle around every person first. Automatic detection covers the faces it finds together. Then refine the result: drag a box to move it, use a corner to resize it, or remove an unwanted box. Adding a manual box also works when automatic detection returns no faces.
To blur faces selectively, use the face-box list to enable or disable each region. You can leave yourself or a speaker who has agreed to appear visible while covering bystanders. On a keyboard, use the arrow keys to move a selected box, Shift with an arrow key to resize it, or Delete to remove it. Review the result after changing the selection.
Choose mosaic, blur, or a solid cover
Mosaic replaces facial detail with visible blocks and makes it obvious that an area has been redacted. It works well when you want the covered areas to be easy to spot. Increase the strength if the blocks still leave too much detail, and check small faces as carefully as large ones.
To blur faces with a softer finish, choose Blur. It smooths facial detail and can blend naturally into a travel or event photo. A weak blur may still leave a person recognizable, so adjust the strength while checking the whole face. Choose a solid cover if you want to hide every pixel within the selected rectangle.
A solid cover fills the selected area with an opaque color. Whichever style you choose, expand the coverage when the default box leaves an eye, cheek, or part of the face outside it. Hair, clothing, tattoos, name badges, and the surrounding scene can also identify someone; face covering alone does not remove those clues.
For group photos, events, and everyday sharing
Blur faces in class photos or school activity pictures before sharing, checking every row and the children near the edges. For conferences, workshops, and community events, keep the people you intend to feature visible and cover other attendees. Automatic detection helps with the first pass, while manual boxes let you refine the selection.
Before you blur faces in travel or street photos, look for strangers in the background, shop windows, and reflections. A meeting screenshot may have small participant tiles or a profile photo that needs a separate box. You can cover other private details manually, but the detector only finds faces, not names, documents, or license plates.
Blur faces without uploading your photo
You can blur faces without sending your photo to a server. Decoding, detection, editing, and export happen inside your browser. The tool is free and does not require registration, so you can start with a local file without creating an account or placing the photo in a cloud editor.
The first time you blur faces, your browser loads the detection code and model from this website. That request downloads tool files rather than uploading your photo, and it can make the first detection take longer. Face detection locates possible faces without identifying people or telling you who appears in the image. Keep the tab open while working.
Original dimensions, with a new PNG download
When you blur faces, the preview may be scaled to fit your screen, but the downloaded PNG keeps the original width and height in pixels. Your photo or screenshot retains its composition and dimensions. The result is a newly encoded PNG with enabled covers applied, even if you started with a JPG, WebP, or HEIC file.
After you blur faces and download the PNG, its file size may differ from the original and may be larger. The export excludes selection outlines and does not copy the source EXIF or GPS metadata. Show original only changes the preview; downloading still applies all enabled covers. Check that the intended boxes remain enabled before saving.
Supported images and detection limits
You can blur faces in one still image at a time, using JPG, PNG, WebP, HEIC, or HEIF. The limit is 25 MB, 24 megapixels, and 12,000 pixels on either side. If a file exceeds those limits, resize a copy before opening it. HEIC and HEIF photos may need extra time for local conversion.
Check each person before sharing: dim lighting, motion blur, a turned head, overlapping people, and very small faces can make detection less reliable. Even without detections, the photo may still contain people. Retry detection or add boxes yourself, then inspect the result. This page edits still photos; it does not process video or batches of separate images.
Questions, answered
Can I blur faces without uploading my photo?
Yes. Detection, editing, and export happen in your browser. The detector files are downloaded from this website; your photo is never uploaded.
Will it find every face?
Small faces, profiles, and partly hidden faces can be missed. To blur faces the detector misses, draw boxes over them yourself. Even if no faces are detected, the photo may still contain faces.
What file do I get after I blur faces?
You get a PNG with the original image width and height and all enabled covers applied. It does not include editing outlines or the original EXIF or GPS metadata.
How do I blur faces in a group photo?
Choose the photo and wait for automatic detection. All faces detected in that photo are covered at once. Check the background and add manual boxes where needed; you do not have to open a separate editor for each person.
Can I blur faces while keeping my own face visible?
Yes. Open the face-box list and disable the box for the person you want to keep clear. Other enabled regions stay covered. If boxes overlap, inspect both of them, because another enabled box can still cover part of that person.
How do I remove a box that is not on a face?
Select the unwanted box and use Remove box, or delete it with the keyboard. You can also disable it in the face-box list. Removing a false detection does not remove the covers on the other people in the image.
Which effect should I choose to blur faces?
Mosaic creates visible blocks, blur softens detail, and solid cover hides the selected rectangle with an opaque fill. Choose the style that fits your use and inspect the result. A subtle blur or fine mosaic may leave recognizable facial detail.
Can I cover the edges of a face, hair, or ears?
Increase extra coverage to expand the boxes, or resize an individual box. Draw another manual box if needed. When you blur faces, check the entire outline: the detector’s rectangle may not include hair, ears, or other identifying details.
Why does it take longer to blur faces the first time?
Your browser first loads the detection code and model from this website. Connection speed, image size, and device performance affect the wait. If detection fails or is canceled, you can still draw boxes manually and finish editing in the browser.
Can I blur faces in an iPhone HEIC photo?
Yes. HEIC and HEIF are supported alongside JPG, PNG, and WebP. The browser converts the photo locally before editing, which may take extra time. The finished download is PNG, so you do not need to convert the HEIC file in another service first.
Will the download include GPS data or editing boxes?
After you blur faces, the PNG is rebuilt from the edited pixels without copying the source EXIF or GPS metadata. Selection outlines and resize handles are excluded. Text, street signs, and other details visible in the photo remain unless you cover them yourself.
Can I blur faces on a phone or in a video?
On a compatible phone browser, yes: you can edit with touch and drag boxes with your finger. The tool processes one still photo at a time, without video tracking or batches of separate files. For another image, choose Change photo.
