# Image crop, rotate and flip

Crop to an aspect ratio, rotate in 90° steps, or mirror an image.

## How it works

Crops to a chosen aspect ratio or to exact pixel bounds, rotates in 90-degree steps and flips horizontally or vertically.

Rotating by 90, 180 or 270 degrees is lossless in principle — the pixels are rearranged rather than resampled. Any other angle requires interpolation and softens the image slightly, which is why photo editors treat straightening as a different operation from rotating.

Cropping to a ratio is the operation most often needed and most often done badly by hand. Common targets: 1:1 for most social avatars, 4:5 for the tallest portrait Instagram allows in feed, 16:9 for video and most presentations, 9:16 for stories and short video, 1.91:1 for link previews.

Flipping is genuinely lossless and reversible. Rotating a JPEG and re-saving is not, because the file is re-encoded.

## Common questions

### Does rotating an image lose quality?

Not at 90-degree steps — the pixels are rearranged, not resampled. Other angles need interpolation and soften the result slightly.

### What aspect ratio should I use for social media?

1:1 for avatars, 4:5 for the tallest in-feed portrait, 9:16 for stories and short video, 1.91:1 for link previews.
