What is image rotation?

Image rotation turns a photo by a chosen angle around its center, clockwise or counterclockwise, so sideways or upside-down content reads correctly. This page works as an online image rotator with quick 90° and 180° presets plus advanced mode for any degree. You can enlarge the canvas so the full rotated image fits, add margin padding, and fill empty areas with transparency or a solid color. Upload, adjust options, preview beside the original, and download PNG in your browser.

Tips for rotating images

Cleaner exports and correct orientation for rotate image tasks.

  1. Enable enlarge for diagonals: Custom angles need enlarged canvas or corners will clip.
  2. 90° presets for EXIF fixes: Simple left/right is fastest for phone orientation mistakes.
  3. White background for documents: Solid white plus margin frames scans on slide backgrounds.
  4. Watch output size: Enlarging a large photo can exceed 8192 px—reduce margin or upload size.
  5. Pair with crop: Rotate first, then trim excess on /crop-image if needed.
  6. Keep the original: Rotation is destructive—archive your source file first.

  4. Product photos: Align SKU shots for consistent catalog thumbnails.
  5. Presentation assets: Rotate screenshots and diagrams for slide decks.
