How to use it
- Choose a rotation, and tick a flip if you need one.
- Add your images. The thumbnails show the new orientation.
- Download them, individually or as a zip.
Why some photos show up sideways
Cameras and phones usually save the picture in the sensor's natural orientation and add a small tag saying which way is up. Most software reads the tag and turns the picture for you. Some older programs, some websites and a few printers ignore it, so the photo appears on its side. Rotating it here bakes the correct orientation into the pixels themselves, which fixes it everywhere.
Flipping and mirroring
Front cameras often save selfies as a mirror image, which makes any writing in the background read backwards. Flip horizontally fixes that. Flip vertically is less common, but useful for scans made upside down on a flatbed, or for creating reflections in designs.
About quality
Rotating by 90° steps does not blur or resample anything; each pixel simply moves. If you save as PNG the result is lossless. JPG output is re-encoded at the quality you set, 92% by default, which is visually identical for photos.
Questions people ask
Why does my photo look fine on my phone but sideways on my computer?
The phone reads the orientation tag and the other software does not. Rotating here fixes the pixels so the tag no longer matters.
Can I rotate by a custom angle, like 5 degrees?
Not here. This tool handles 90° steps and flips, which never lose sharpness.
Will rotating reduce quality?
Not for PNG. JPG output is re-saved once at high quality.
