Rotate and flip images

Fix a whole folder of sideways photos at once. The rotation is baked into the pixels, so it looks right in every program — not only the ones that read the EXIF orientation flag.

Loading the tool…

How it works

  1. Drop your images.
  2. Pick the rotation and, if needed, a flip.
  3. Convert and download.

Why nothing is uploaded

Every operation on this page is done by code running inside your browser tab, using the same engine that renders web pages. The file is read from disk into your tab’s memory, transformed there, and written back out as a download. It is never sent anywhere — not to us, not to a third party.

Verify it yourself

  1. Open your browser’s developer tools (F12) and select the Network tab.
  2. Load your file and run the tool.
  3. The only requests you will see are the tool’s own code and, once cached, none at all.

Frequently asked questions

My photo looks upright here but sideways elsewhere. Why?

Because the camera stored it sideways plus an EXIF “rotate me” flag, and only some programs obey that flag. Rotating here writes the pixels in the right order and resets the flag, which fixes it everywhere.

Does rotating a JPEG lose quality?

A little: the file is decoded and re-encoded, so one more generation of JPEG loss is added. At quality 88 or above it is invisible in practice. Choose PNG output if you need it to be exactly lossless.

Are the images uploaded to convert them?

No. The image is decoded by your browser, redrawn on a canvas and re-encoded there. Load the page, switch your connection off and the conversion still works — that is the proof.

Is there a size or batch limit?

None that we impose. Drop a hundred files if you like; they are processed one after another with a progress bar, and the ceiling is your device’s memory.

What happens to EXIF and GPS data?

It is dropped by default, which is usually what you want before sending a photo to anyone. Tick “Keep EXIF” if you need the capture date and camera preserved in a JPEG output.
