most social media sites already do that for you . Unless you upload the image as a document, most media sites automatically remove the exif and compress the img.

YSK - for all the things that can make your life easier!
The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:
Rules (interactive)
Rule 1- All posts must begin with YSK.
All posts must begin with YSK. If you're a Mastodon user, then include YSK after @youshouldknow. This is a community to share tips and tricks that will help you improve your life.
Rule 2- Your post body text must include the reason "Why" YSK:
**In your post's text body, you must include the reason "Why" YSK: It’s helpful for readability, and informs readers about the importance of the content. **
Rule 3- Do not seek mental, medical and professional help here.
Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.
Rule 4- No self promotion or upvote-farming of any kind.
That's it.
Rule 5- No baiting or sealioning or promoting an agenda.
Posts and comments which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.
Rule 6- Regarding non-YSK posts.
Provided it is about the community itself, you may post non-YSK posts using the [META] tag on your post title.
Rule 7- You can't harass or disturb other members.
If you harass or discriminate against any individual member, you will be removed.
If you are a member, sympathizer or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people and you were provably vocal about your hate, then you will be banned on sight.
For further explanation, clarification and feedback about this rule, you may follow this link.
Rule 8- All comments should try to stay relevant to their parent content.
Rule 9- Reposts from other platforms are not allowed.
Let everyone have their own content.
Rule 10- The majority of bots aren't allowed to participate here.
Unless included in our Whitelist for Bots, your bot will not be allowed to participate in this community. To have your bot whitelisted, please contact the moderators for a short review.
Rule 11- Posts must actually be true: Disiniformation, trolling, and being misleading will not be tolerated. Repeated or egregious attempts will earn you a ban. This also applies to filing reports: If you continually file false reports YOU WILL BE BANNED! We can see who reports what, and shenanigans will not be tolerated.
If you file a report, include what specific rule is being violated and how.

Bots including Mark Zuckerberg is going to keep all your data before "doing that for you".
Also on mobile what works for me when uploading a photo, I generally screenshot and upload that screenshot. Never upload the "original" photo.

You want to use the Metadata Anonymisation Toolkit not trust Microsoft to not fuck you
On linux you should use exifcleaner. The amount of info exiftool can pull from your photos is shocking. I thought Signal exifcleans but not clean enough apparently
I can recommend ffshare on android. Works like a pipe in unixland.
Since we're on Lemmy, most people probably use Linux. You can use mat2 for this. It's CLI tho
exiftool
I bet there are some poorly-built automatic scrapers out there harvesting EXIF tag data and not being too careful about sanitizing what they find.
I've always been curious how one could verify that all that exif data was certainly removed fully
There are EXIF data viewers. You can just look at it. ExifTool and so forth. You can also use it to remove such data if you don't trust Windows to do it for you.
At least a subset of EXIF data can be viewed in Windows Explorer in your file properties. Technically any device or app can store any custom field within the EXIF data so long as it fits within the data size limitations, so it's certainly possible there could be gumpf in there that Explorer won't display.
I trust windows about as much as every kgb employee
with opencamera you can check the option to don't save any extra data
I’m pretty sure Lemmy strips it
Why would I use Windows?
