Rotate & Flip Image
Quickly fix inverted or sideways photos. Rotate images 90 degrees clockwise or counter-clockwise, and flip horizontally or vertically with live canvas rendering.
Upload Image to Rotate or Flip
Rotate 90°, 180°, 270° or flip horizontally and vertically in browser memory.
Step-by-Step Instructions
Upload Your Photo
Select or drop your photo, scan, or graphic file into the image rotation tool.
Select Rotation Angle or Flip
Click 90° Clockwise, 90° Counter-Clockwise, 180° Inversion, or flip horizontally/vertically (mirror reflection).
Fine-Tune Custom Angle Slider
Use the fine angle slider (-45° to +45°) to straighten crooked horizon lines or tilted document scans.
Download Corrected Image
Export your perfectly oriented photo in PNG, WebP, or JPG format with zero quality loss.

Frequently Asked Questions
Why do photos taken on smartphones sometimes appear sideways or upside down on computers?
Smartphones embed orientation tags in the image's EXIF metadata rather than rotating the physical pixel grid. When opened in software that ignores EXIF tags, the photo displays in its raw sensor orientation. This tool applies true physical pixel rotation to fix the orientation permanently.
How does the horizon straightening angle tool work?
The fine rotation tool applies an affine transformation matrix on an HTML5 canvas, letting you rotate the image by tenths of a degree against a grid guide. It automatically recalculates bounding box bounds to prevent clipping.
Does rotating an image 90 degrees degrade its quality?
Orthogonal rotations (90°, 180°, 270°) transpose pixel coordinates directly without resampling distortion. When exported as PNG or high-quality JPEG, visual fidelity is 100% preserved.
Are my uploaded photos or scans stored anywhere?
No. All canvas transformations execute locally on your computer's CPU/GPU. No images are transmitted over the internet.
