What happens to the background when rotating at an arbitrary angle (like 15°)?

When an image is rotated by an angle other than a multiple of 90°, the corners outside the original image bounds become transparent in the exported PNG.

Does flipping an image reduce its quality?

No. Flipping mirrors pixel coordinates along an axis without lossy compression or resampling, preserving original detail perfectly.

Can I flip and rotate an image at the same time?

Yes. Rotation angles and horizontal/vertical flips can be combined simultaneously in the canvas transformation matrix.

Are rotated images uploaded to your server?

No. All geometric canvas rotations and matrix transformations occur purely in local browser memory with 0 bytes transmitted.

Key features

Quick 90-Degree Increments

Instantly rotate clockwise or counterclockwise in 90° steps with automatic canvas dimension swapping.

Continuous 360-Degree Custom Angle

Fine-tune rotation angle with an interactive slider from 0° to 359° for leveling crooked horizons.

Horizontal & Vertical Mirror Flipping

Flip images along horizontal and vertical axes independently or in combination with rotation.

Transparent Alpha Channel Preservation

Rotated canvases are exported to PNG, preserving transparent areas and corners created by angled rotations.

Examples & use cases

Portrait to Landscape 90° Correction

Correct orientation on a phone photo taken sideways.

Input:

Source: 1080 × 1920 px sideways phone photo, Action: Rotate +90°

Result:

Transformed: 1920 × 1080 px correctly oriented horizontal photo

Selfie Horizontal Mirroring

Fix front-facing camera mirroring on a portrait.

Input:

Source: 1200 × 1600 px selfie photo, Action: Flip H

Result:

Transformed: 1200 × 1600 px natural mirror reflection with identical dimensions

Horizon Leveling at 3° Tilt

Correct a slightly crooked landscape horizon.

Input:

Source: 2000 × 1500 px landscape with tilted horizon, Action: Custom Angle 357° (-3°)

Result:

Transformed: Level horizon with transparent bounding canvas exported to PNG

Frequently asked questions

Yes. Rotating by 90° or 270° swaps the image width and height (e.g. a 1920×1080 image becomes 1080×1920). Rotating by 180° or 360° maintains the original width and height.
