What is an image rotator?

An image rotator lets you spin a photo to a precise angle and mirror it along its horizontal or vertical axis. Use it to fix sideways photos that imported in the wrong orientation, level a tilted horizon to within a single degree, mirror selfies that were captured back-to-front, or generate flipped variants for design layouts and side-by-side comparisons. This tool runs entirely inside your browser using the HTML Canvas API, so the original file never leaves your device, and exports are saved at the original pixel dimensions with no quality loss for PNG and configurable JPG/WebP compression.

How to rotate or flip an image

1
Upload your image
Drag a JPG, PNG, WebP, GIF, BMP, or AVIF file onto the drop zone, or click Choose image to open the file picker.
2
Choose a rotation angle
Use the Rotate left or Rotate right buttons for quick 90° turns, or drag the slider for any angle between -180° and +180°.
3
Optionally flip the photo
Toggle Flip horizontal to mirror left-to-right, or Flip vertical to mirror top-to-bottom. Combine with rotation as needed.
4
Pick an output format
Choose PNG to keep transparency at the rotated corners, or JPG/WebP for smaller file sizes (with a quality slider).
5
Download the result
Click Download rotated image to save the file at full source resolution to your device.

How rotation is computed

For a rotation of θ degrees, the bounding box of the rotated image grows to:
 
  newWidth  = |w · cos θ| + |h · sin θ|
  newHeight = |w · sin θ| + |h · cos θ|
 
The canvas is resized to that bounding box, the origin is moved to its center,
the context is rotated by θ, optionally scaled by (-1, 1) or (1, -1) to flip,
and the image is drawn centered at (-w/2, -h/2). This guarantees no corner clipping
at arbitrary angles while keeping rotations of 90° and 180° pixel-exact.

Multiples of 90° produce a perfect pixel-for-pixel copy with no resampling. At any other angle, bilinear filtering smooths the rotated edges; PNG output preserves transparent corners while JPG/WebP fill them with the chosen background color.

Examples

Source	After rotation
4000×3000 photo, rotate 90°	3000×4000 photo (portrait) Pixel-exact rotation, no resampling.
1920×1080 banner, rotate 7°	2037×1262 (auto-fit canvas) Tilted corners filled with chosen background.
Selfie, flip horizontal	Mirror-image selfie Same dimensions, no rotation applied.

Common use cases

Fix photos that imported sideways from a phone or camera with the wrong EXIF orientation.
Level a tilted horizon line by rotating one or two degrees.
Mirror a selfie that was captured with the front camera in reversed orientation.
Create a flipped version of a design asset for a side-by-side mockup.
Rotate a scanned document back to upright before sharing or printing.
Generate four 90°-stepped variants of an icon for symmetry testing.
Flip a screenshot horizontally to anonymize the side a UI control sits on.

Frequently asked questions

Are 90° and 180° rotations lossless?

Yes. At multiples of 90°, the rotation is a pure pixel reorder with no resampling, so the output is bit-for-bit equivalent in quality to the source.

What happens to the corners when I rotate by an arbitrary angle?

The canvas auto-fits the rotated bounding box, so no part of your image is clipped. The empty triangles at the corners are transparent in PNG output, or filled with white/black for JPG and WebP (you can pick which).

Will my original file be uploaded anywhere?

No. The rotation runs entirely in your browser via the HTML Canvas API. Your image never leaves your device.

Does the output preserve the original resolution?

Yes. The export canvas is sized to the full rotated bounding box of the source resolution, so you keep every pixel of the original.

Can I combine rotation and flipping?

Yes. Rotation and flips compose in a single canvas pass, so the final image reflects every transform you applied in the controls.

Why does my JPG file have white corners after rotating 12°?

JPG cannot store transparency. The corners that fall outside the original photo must be filled with a solid color. Switch to PNG output if you need transparent corners.
