Rotate an image
Turn an image 90° left or right — repeat for 180°. The pixels are remapped losslessly.

A quarter-turn is the one rotation that is mathematically free. Rotating by 90° maps every pixel exactly onto another pixel position, so nothing is blended, interpolated, or invented — the result contains precisely the same pixel values as the original, rearranged. Rotating by an arbitrary angle like 7° cannot make that promise, because output pixels then land between input pixels and have to be averaged.
The most common reason to need this is a photo that appears sideways in one program and upright in another. That happens because cameras often store the orientation as a metadata flag rather than rotating the pixels themselves, and not every piece of software honours the flag. Rotating here writes the correct orientation into the pixels, which fixes it everywhere.
How it works
- 1
Load an image by dropping it onto the workspace, browsing, or pasting from your clipboard.
- 2
Click Rotate left or Rotate right for a quarter turn. Click the same button twice for 180°, which is what an upside-down photo needs.
- 3
Watch the dimensions in the info panel — a quarter turn swaps width and height, so a 4000×3000 photo becomes 3000×4000.
- 4
Download as PNG to keep the result completely lossless, or JPEG or WebP if file size matters more.
Frequently asked questions
Does rotating lose quality?
A 90° rotation remaps pixels one-to-one, so no detail is lost in the rotation itself. The only loss comes from the export format: save as PNG and the result is identical to the original data, save as JPEG and you get one round of normal JPEG compression.
Why does my phone photo show up sideways in the first place?
Phones usually record which way you were holding the camera as an EXIF orientation tag instead of rotating the stored pixels. Software that reads the tag displays it correctly; software that ignores it shows the raw sideways image. Rotating here bakes the orientation into the pixels so both behave the same.
Can I rotate by an arbitrary angle to straighten a horizon?
Not with this tool — it does quarter turns only. Straightening by a few degrees requires resampling every pixel and then cropping away the empty corners the rotation creates, which is a different operation with a real quality cost, whereas quarter turns are free.
How do I flip or mirror an image instead?
Flipping is a different operation from rotating: a mirror image cannot be produced by any amount of rotation. This tool does not currently flip, and it is worth being clear that rotating 180° is not the same as flipping vertically — the two give different results for anything containing text.
Is my photo uploaded when I rotate it?
No. The rotation is a canvas transform performed in your browser, so the image never leaves your device. That also means rotating a very large photo is limited only by your own device’s memory rather than by an upload size cap.
