Is my photo really not uploaded?
Correct. Everything runs in your browser. You can verify it by opening the Network tab in your browser's developer tools (F12) and dropping a large photo — you will see no outgoing request that contains your file. After the page loads its own JavaScript and CSS once, the tool can run with the internet disconnected.
What metadata exactly is removed?
For JPEG: all APP1 (EXIF, XMP), APP2 (ICC, MPF), APP13 (Photoshop, IPTC) and APP14 (Adobe) segments. For PNG: tEXt, iTXt, zTXt, eXIf and Adobe XMP chunks. For WebP: the EXIF, XMP and ICCP chunks. The actual pixel data and compression are not touched.
Does removing EXIF reduce image quality?
No. EXIF is a separate metadata block inside the file. Removing it does not re-encode the image — the pixels and the JPEG/PNG/WebP compression are exactly as they were. The file becomes a few kilobytes smaller because the metadata is gone.
Can I keep some metadata and remove the rest?
Yes. Each file card has buttons to remove only specific categories — e.g. "Remove only GPS" keeps everything except location, "Remove only Camera info" keeps everything except make/model/serial. The default "Remove all" wipes the entire metadata block at once.
Do social networks already remove EXIF?
Some do, some don't, and the rules change without notice. Facebook, Instagram and Twitter strip most EXIF on public posts but keep some internally for moderation and analytics. WhatsApp, Telegram (when "send as file"), Discord, email attachments, blogs, forums, eBay listings, classifieds, cloud drives — almost all of these keep EXIF intact. The safe rule is: never assume any service removes EXIF for you.
Why don't you show the GPS location on a map?
Because loading a map tile would send your coordinates to a third-party service (Google, OpenStreetMap, Mapbox), which contradicts the privacy promise of this tool. Instead we show the latitude and longitude as plain text, and you can decide for yourself whether to copy them into a map elsewhere.
What about HEIC photos from iPhones?
EXIF can be read from HEIC files in this tool. Stripping HEIC requires re-encoding the image, which most browsers cannot do natively. For full stripping of HEIC, the safest path is to first convert to JPEG using your operating system or photo app, then strip with this tool.
Is the tool open source?
The code is delivered to your browser as plain JavaScript files and is fully readable. Right-click → View Source, or open the .js files directly. There is no minification or obfuscation that hides what the tool does.
What's the catch? Why is this free?
There is no catch. The tool is provided as a free service by Midgard MUD — a free Norse-mythology online role-playing game. Some visitors discover Midgard through this tool and try the game, but you are not asked to do so and the tool works fully without any account or interaction with the MUD.
Can I use this on my phone?
Yes. The tool works in any modern mobile browser — Safari on iOS, Chrome and Firefox on Android. On iOS you may have to choose "Files" instead of "Photos" in the picker to access HEIC originals.
Why does my photo still show some date/dimension info?
The image dimensions (width × height) and the file size are inherent to the image itself, not metadata — they cannot be hidden without re-encoding. The "Date Modified" timestamp on the downloaded file is set by your operating system at the moment of saving and is unrelated to EXIF. To control that, set the file's modification date manually in your file manager after download.
Are there any limits on file size or number of photos?
There is no hard limit. Practical limits are set only by your device's memory: a typical phone or laptop comfortably handles 50+ photos at 20 MB each. For very large batches (hundreds of files), processing in two or three runs is more responsive than one giant batch.
Does the tool also remove watermarks from photos?
It depends on what kind of watermark you mean. Visible watermarks (logos, text overlays, "Shutterstock"-style stamps) are baked into the image pixels and CANNOT be removed by metadata stripping — and removing them is often illegal under copyright law (e.g. § 95c German Copyright Act). This tool will not do that. However, "invisible" watermarks stored in metadata fields — IPTC Copyright, XMP dc:rights, Photoshop IRB markers, Stock-photo IDs in APP13 — ARE removed when you click "Remove all metadata". The same applies to camera serial numbers and editing-software fingerprints. The tool removes everything in the metadata block; it does not touch the pixels.
