Frequently asked questions
- Can pixelation be reversed?
- No — information is permanently destroyed. This makes it a safe way to hide text or faces in screenshots.
- Are my images uploaded to a server?
- No. This tool runs entirely in your browser — the image is read from your device, processed locally, and never sent anywhere. You can disconnect from the network after the page loads and it still works.
- Is this tool really free?
- Yes. MakeMyImgs tools are free to use with no watermarks or account signup. Server-backed tools may apply temporary traffic limits when the API is busy.
