Tool
Rotate & Flip Image
Fix sideways and upside-down photos, straighten a crooked horizon by a few degrees, or mirror an image to un-flip a selfie or a reversed scan. Work on each image separately or all of them at once, and the result is saved into the file.

You can also paste an image with Ctrl+V (⌘V on a Mac).
Your images stay on your device. Nothing is uploaded.
How to rotate or flip an image
- Choose or drop your images.
- Use each image’s rotate and flip buttons, or turn or flip them all at once. Enter an angle to straighten by a few degrees.
- Select “Save images” and download the result.
Private by design
Most online image tools upload your pictures to their servers. This one doesn’t: Rotate & Flip Image runs entirely in your browser, so family photos, IDs, screenshots and client work never leave your device. It’s free, with no watermark and no limit on how many images you process, and you don’t need an account.
Questions
Why does my photo look sideways in some apps but not others?
Phones often save photos sideways with a note saying which way is up, and some apps ignore the note. Rotating here saves the pixels the right way up, so the photo looks right everywhere.
How do I un-mirror a selfie?
Flip it horizontally. Front cameras often save the mirrored view you saw on screen, so text in the photo reads backwards; flipping it shows the scene as everyone else saw it.
What's the difference between flipping and rotating?
Rotating turns the image around its centre, so text stays readable. Flipping mirrors it, so text reads backwards. Flipping both ways gives the same result as rotating by 180°.
What happens to the corners when I rotate by an angle?
The image is turned and the canvas grows to fit it. The new corners are transparent in PNG and WebP, or filled with the background colour you choose in JPG. Crop the result to trim them.
Is rotating or flipping lossless?
PNG output is lossless. JPGs are re-saved at quality 92 by default, which you can raise to 100 so the difference can't be seen.
Are my images uploaded?
No. Every tool runs in your web browser, so your images are read, changed and saved on your own device and never sent to LabAnvil or anyone else. Once the page has loaded, the tools even work offline.
Is it free? Do I need an account?
Free, with no watermark, no daily limit, no account and no cap on file size beyond what your device's memory can handle.
