Rotate and flip

Rotate and flip turns an image by 90, 180 or 270 degrees, by any fine angle from -180 to 180, or mirrors it across either axis, entirely inside your browser tab. The quarter turn and the fine angle add together, so a scan lying on its side and three degrees crooked is fixed in one pass. Right angles and flips move pixels rather than resampling them; any other angle resamples the whole image and grows the canvas to hold the rotated corners, which take a background colour you pick.

How it works

  1. Add your images Drag one or more images onto the drop area, or browse for them. Every file in the queue takes the same turn.
  2. Pick a quarter turn Choose 0°, 90°, 180° or 270°. These keep every pixel exactly where it was, just in a new place.
  3. Add a fine angle if you need one Drag the fine angle slider, one degree at a time from -180° to 180°. It adds to the quarter turn, and a background swatch appears to fill the corners an off-axis turn exposes.
  4. Flip horizontally or vertically Switch on either toggle, or both. Mirroring is exact at any angle.
  5. Apply and download Choose an output format — keep the original, WebP, PNG or JPEG — adjust the filename pattern if you want, then apply. One file downloads on its own; several arrive as a ZIP.

Questions

Does rotating a JPEG lose quality?
The rotation itself does not, at a right angle. A 90, 180 or 270 degree turn and either flip move pixels to new positions without resampling them, so no detail is invented or blurred. The file is still re-encoded on the way out, so if you want to avoid a second JPEG generation, set the output format to PNG or WebP.
What happens if I rotate by an angle that is not a right angle?
Every pixel is resampled and the canvas grows so the rotated corners are not clipped. That leaves empty triangles at the corners of the new canvas, which are filled with the background colour you choose (white by default). The tool shows this warning on screen before you apply.
Can I rotate a whole folder of images at once?
Yes. Drop as many images as you like and the same turn, flip and output format apply to every one. A single result downloads directly; more than one is packed into a ZIP.
