How ExifVoid Works
A transparent look at what we do, how we do it, and why your privacy is genuinely protected.
What is EXIF metadata?
Every photo you take with a smartphone or digital camera contains hidden data called EXIF (Exchangeable Image File Format) metadata. This invisible information is embedded directly into the image file and travels with it wherever it goes — social media uploads, email attachments, cloud storage.
This metadata can include your exact GPS coordinates (often accurate to within a few metres), the make and model of your device, unique serial numbers that can link photos back to your specific camera, timestamps showing exactly when a photo was taken, and even the software you used to edit it.
Why is this a problem?
When you share a photo online — on marketplaces like eBay, on social media, in forums, or even via messaging apps that don't strip metadata — anyone who downloads that image can extract this data in seconds. That means a stranger could pinpoint your home location from a casual photo of your pet, or link multiple anonymous uploads to the same physical device.

How ExifVoid is different
Most metadata removal tools require you to upload your photos to their servers for processing. This defeats the purpose — you're handing your private data (the very data you want to remove) to a third party.
ExifVoid works entirely within your web browser. When you drop a file into the tool, JavaScript running on your device reads and processes the file locally. The image data never leaves your computer. There are no server uploads, no temporary cloud storage, no data retention.
The technical approach
ExifVoid uses canvas re-encoding to strip metadata from your images. When you clean a file, the browser loads the image onto an HTML canvas element and re-exports it as a fresh file. Because canvas export creates a completely new image, no metadata from the original file carries over — it is all stripped automatically.
A key advantage of this approach is that the browser automatically handles EXIF orientation tags when rendering to canvas. This means your cleaned photos always display with the correct orientation, regardless of how the original camera saved them.
For JPEG files, re-encoding is performed at 95% quality — a level where the visual difference from the original is imperceptible to the human eye. The result is a clean, correctly-oriented photo with all hidden metadata completely removed.
Verify it yourself
You don't need to trust our word. Open your browser's Developer Tools (F12), go to the Network tab, and watch what happens when you process a file. You'll see zero outbound requests containing image data. The only network activity is the initial page load itself.
You can even disconnect from the internet after the page loads and the tool will continue to work normally. Try it.
