How To Blur Faces and Strip Metadata from Images


Image Scrubber

This new app enables non-technical users to quickly blur parts of images while also erasing any identifying metadata.

Blur or mask anything in an image and remove metadata (EXIF data) using your mobile, your web browser or offline with this app.

Image Scrubber is a small app that does a few things well. It’s a fast and simple way to blur or mask parts of an image and strip metadata from photos. It’s easy to use; load a photo into the app and it will check for EXIF data and if present, will allow you to delete the data. After deleting data, or if there’s no data present you then edit the image.
The editing options are:
Blur – change brush size and radius
Paint – black is the only color, produces solid mask
Rotate image

The app loads images from your device. You can use drag and drop to open an image or open an image from a file or folder, strip metadata if present, drag to blur or mask areas and then save the image. Maximum size is 2500x2500 pixels - larger images will be scaled down.

Image Scrubber was developed for anonymizing photos taken at protests to allow selective parts of images to be blurred or masked.
It’s also useful for blurring out sensitive or personal information from photos, or anything else you don’t want visible.
The blur function runs on top of shuffled, noisy, upscaled pixels and all processing happens in the browser, no information is stored anywhere.

I just checked. It's not available from the Apple Store. Is it Android only?

It's a web app that works inside your a browser. Most browsers work fine on Android and iOS. 

rhiannon, I think you might be able to help with Waterfox. I started using it and loved it far bettter than Firefox. However a problem arose and I figured out what was causing it and contacted the developer who became kind of snotty and refused to fix the problem.

The problem arises in how WF handles memory. FF, if you recall, opens a new block of memory if too many tabs are opened. In my work I generally have 80 or more tabs open at once, and FF has them sectioned off in 8 or 10 separate blocks of memory. WF however, tries to keep them all in one block of memory which slows the computer down severely. A second problem arises as I save the files to disk. It doesn't release the memory, so even if there is only one tab left open, that same huge block of memory sits there intact, slowiing my machine down to a crawl. It takes existing WF to release that memory.

I tried explaining that to the WF developer and all he said to me was, he designed it to be a "single process operation". I asked him what that meant, but he never answered me. I will keep checking and when he does an upgrade on WF, I'll try it again to see if it still has the same problem.

Thanks ... /ed

Are you using the classic version of Waterfox? If I understand correctly, the newer versions of Waterfox and Firefox handle memory differently than older versions. Older version handle memory as a single process, newer versions handle memory as multiprocesses.

There are some about:config tweaks that will increase the amount of resources allocated to older versions of Waterfox or Firefox. Be aware that changing some of them like the process count can put more of a load on your processor, others such as increasing the cache are usually fine. Look up Firefox 'increase Firefox memory about config' in your preferred search engine. Most of the config changes should work in Waterfox.
