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.

Cropping changes the aspect ratioRemoving edges changes the width-to-height ratio. If you need a specific ratio, crop to it deliberately. See Common aspect ratios explained.

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.

Questions

Does rotating an image reduce its quality?

Rotating in 90-degree steps does not, because the pixels are simply rearranged. Free rotation by an arbitrary angle does resample the image and can soften it slightly.

Is cropping reversible?

No. Cropping permanently removes the pixels outside the crop. Keep the original if you might need the full frame later.

Do these tools upload my images?

No. Utilumo's image tools decode, edit, and export pictures inside the browser tab. The files are never uploaded or stored on a server.
