Rotate in exact 90° steps or mirror horizontally/vertically, with a live preview. The classic use case: phone photos that display sideways in some apps because they rely on an orientation flag other software ignores — the copy you download here is physically rotated, so it's right-side-up everywhere, forever.
Frequently asked questions
Why do my phone photos show sideways in some apps?
Phones often save the sensor's native orientation plus an EXIF flag saying "display rotated". Apps that ignore the flag show the raw orientation. Physically rotating the pixels — what this tool does — fixes it in every app.
Is rotating lossless?
For PNG, completely — 90° rotations just rearrange pixels. JPEG output re-encodes once at high quality; if you need strictly lossless JPEG rotation repeatedly, rotate once and keep that copy as your original.
What's the difference between rotating 180° and flipping?
Rotating 180° turns the image upside down; flipping mirrors it. Text reads backwards in a flip but stays readable (upside down) in a rotation — if text looks mirrored, you want flip horizontal to undo it.
