I started this because similar Chrome extensions were paywalling features and I wanted a free, open source alternative. I'm new to this, so I would appreciate feedback and tips if anyone has some!

A lot of folks accepting image uploads don't realize they need to remove the exif data from the images, as that often leaks gps coordinates if they were taken using a cell phone. With imagemagick, you can use the `-strip` flag[0] when processing the images to remove that info.

It's shame all exif info is stripped. I like to see the camera info, such as focal length, aperture and what lens too for interchangeable lens cameras.

A responsible site will strip this on the user’s behalf, but no one should rely on that.

If I want to be lazy about it and quality doesn’t matter, I’ll take a screenshot as a quick way to strip EXIF data, the location being the key piece I want gone.

I don't grant my camera app location permissions, so the images are never tagged with gps in the first place, but I also will screen shot pictures before sending them anywhere.

IIRC This is how John McAfee's location was leaked when he was on the run, a Vice reporter took a selfie with him and uploaded it to the website without stripping the EXIF data

checks out for me, just spot checked this image https://github.com/ianare/exif-samples/blob/master/jpg/Canon.... I loaded as an unpacked extension, works great so far.

Looks good too for imgur which typically has no metadata on the images https://imgur.com/i2iHgAI https://i.imgur.com/i2iHgAI.jpeg

Thank you for this useful extension.

Glad it worked for you - thanks for the feedback!

The extension looks native to the system in the screenshot which is impressive. It might be helpful for some users if file size and type are added to the list.

I'll consider adding that, thanks!

This is something I plan to do eventually! I use a Chromium-based browser on a day-to-day basis, so that was what I wanted to tackle first.
