How to crop, rotate, and flip images
Short answer
Crop to keep only the part of an image you want, rotate to fix sideways or upside-down photos, and flip to mirror an image. Each is a quick, common edit you can do in the browser without uploading the file.
Three basic edits
- Crop removes the outer parts of an image, changing its framing and aspect ratio
- Rotate turns the whole image, usually in 90-degree steps to fix orientation
- Flip mirrors the image horizontally or vertically
When to use each
Crop to focus on a subject, remove distractions, or hit a required aspect ratio for a platform. Rotate to fix a photo that came in sideways. Flip to mirror a selfie or correct a reversed scan.
A note on quality
Rotating by 90, 180, or 270 degrees and flipping do not lose pixel quality, because no resampling is needed. Cropping only discards pixels rather than stretching them. Re-saving as JPG, however, applies compression again, so keep a master copy if you will edit repeatedly.
