Rotate images online by any angle

Rotate one image or a whole batch by any angle, including 90, 180, and 270 degrees, plus axis mirroring. Local processing keeps your files private. Free, no uploads, no signup.

Type any angle in degrees or use 90, 180, and 270 presets. Combine rotation with horizontal or vertical mirroring to fix orientation issues across a whole batch.

Understanding image rotation and orientation

Image rotation changes the angle at which pixels are displayed without altering the content itself. The most common rotations are 90, 180, and 270 degrees, which correspond to quarter, half, and three-quarter turns. These fix orientation problems caused by cameras that embed EXIF orientation tags instead of physically rotating the pixel data.

Many smartphones save photos in landscape orientation regardless of how you held the phone, relying on an EXIF tag to tell viewers how to display it. When you strip metadata or upload to platforms that ignore EXIF, the image appears sideways. Rotating the actual pixels solves this permanently.

Arbitrary-angle rotation (like 15 or 45 degrees) creates a larger canvas because the rotated rectangle no longer fits its original bounding box. The extra space is filled with transparency (PNG/WEBP) or a background color (JPG). This is useful for creative effects, straightening slightly tilted scans, or correcting horizon lines in landscape photography.

Combining rotation with mirroring (horizontal or vertical flip) covers every possible orientation correction. The eight EXIF orientation values map to combinations of 0/90/180/270 rotation plus an optional horizontal mirror, so this tool can fix any orientation issue in a single operation.

Common use cases

  • Fixing smartphone photo orientation: Correct sideways or upside-down photos that lost their EXIF orientation data during upload, email forwarding, or metadata stripping.
  • Straightening scanned documents: Apply small-angle rotation to scanned pages that went through the feeder slightly crooked, making text perfectly horizontal for OCR processing.
  • Creative photography effects: Tilt images at artistic angles for dynamic social media posts, magazine layouts, or presentation slides that need visual energy.
  • Preparing images for print layouts: Rotate landscape photos to portrait orientation (or vice versa) to fit specific print templates, poster dimensions, or frame aspect ratios.

Technical details

Rotation method
The Canvas API applies a 2D rotation transform before drawing the image. For 90/180/270 degrees this is lossless in terms of pixel positioning. Arbitrary angles use sub-pixel interpolation.
Canvas expansion
Non-right-angle rotations produce a larger output canvas. The bounding box grows to contain the full rotated rectangle. Empty corners are transparent for PNG/WEBP or white for JPG.
Mirror operations
Horizontal flip mirrors left-to-right (like a mirror reflection). Vertical flip mirrors top-to-bottom (like a water reflection). Both can combine with rotation.
Quality preservation
Every rotation re-encodes through Canvas. Use PNG for lossless output or set JPG/WEBP quality to 95+ to minimize generation loss on repeated rotations.

How to rotate an image online

Rotate single or multiple images to any angle and save the result.

  1. Drop images into the rotator or pick them from your device.
  2. Set the rotation angle in degrees or use 90, 180, 270 presets.
  3. Optionally mirror horizontally or vertically.
  4. Click download to save the rotated file, or a ZIP if the batch contains several files.

Frequently asked questions

Does rotation re-encode the file?

Yes. Rotated images are written back through the Canvas API, so the output is a new encoding. Use a low compression setting to preserve quality.

Can I rotate transparent PNGs?

Yes. Transparency is kept intact in the exported file.
