File security

Every working tool on this site processes your image inside your own browser. No copy of your file is sent anywhere, because there is no upload code and no server that could receive one.

What happens when you select a file

  1. The browser hands the page a reference to the file on your disk. Selecting a file does not move it.
  2. The file is decoded into pixels in memory, using the browser's own image decoder — the same one that renders images on any web page.
  3. Those pixels are drawn onto a canvas, resized, cropped or adjusted according to the settings you chose.
  4. The canvas is re-encoded to JPEG, PNG or WebP by the browser's built-in encoder, producing a new file in memory.
  5. Downloading saves that in-memory file to your disk. Closing or reloading the tab discards everything.

How to verify this rather than trust it

  • Watch the network. Open your browser's developer tools, go to the Network panel, then process an image. No request carrying your file appears, because none is made.
  • Go offline. Load a tool page, disconnect from the internet, then process an image. It still works. Anything uploading your file could not.

What is stored on your device

The site sets no tracking cookies and requires no account. Nothing you process is written to local storage. Standard server access logs record page requests — the address of the page, the time, a user agent — which is ordinary web-server behaviour and contains no image data.

Limits worth knowing

  • Very large images can exhaust the tab's memory and fail. That is a browser limit, not a size policy, and the tool tells you when it happens.
  • Lossy re-encoding is not reversible. Keep your original — the tools never overwrite it, but a compressed copy cannot be restored to its original quality.
  • Re-encoding through the canvas drops EXIF metadata including GPS coordinates, because only pixel data crosses to the new file. If removing location data is the point of what you are doing, confirm the result in an EXIF viewer before publishing.
  • Tools marked as in development do not run here at all. When one is completed, if it can only work by uploading your file, that will be stated on its page before you select anything.
