About

A tool to rotate images 90°/180° with a single click, or freely rotate them to any angle. It also supports horizontal and vertical flipping.

Perfect for correcting sideways smartphone photos or fine-tuning the orientation of design assets.

Glossary

Rotation
An operation that rotates an image by a specified angle around its center. This tool supports 90°/180° rotation with buttons and 1-degree micro-adjustments with a slider, which is useful for fixing tilted photos.
Flip Horizontal
An operation that creates a mirror image by flipping the image along a vertical center line. It is often used to correct mirrored selfies taken with front cameras or to reverse the direction of design materials.
Flip Vertical
An operation that turns the image upside down along a horizontal center line. It is useful for correcting upside-down landscape photos or creating visual effects like water reflections.
EXIF
Metadata embedded in digital photos, including shooting date, camera model, location, and the "Orientation" flag. The orientation flag sometimes causes images to display sideways; this tool fixes it by properly rotating and saving the image.
Canvas API
A standard HTML5 technology for dynamically drawing and processing pixels in the browser. By using this API, the tool safely and quickly processes image rotations entirely on your device's memory without sending images to a server.
Radian
A mathematical unit of angle. Unlike degrees (360° for a full circle), it defines angles based on arc length, where a full circle is 2π radians. It is the required unit for internal calculations when rotating via the Canvas API.
PNG Format
An image format featuring lossless compression (no quality loss) and support for transparency (alpha channel). It is ideal when you rotate an image at a free angle and want to keep the resulting triangular margins transparent.
JPEG Format
A lossy compression image format best suited for complex photos. It significantly reduces file sizes by discarding visually imperceptible data. However, since it does not support transparency, any margins created by rotation will be filled with white.

FAQ

Q.Can I retry rotating or flipping as many times as I want?
Yes, you can retry endlessly. Use the 90° buttons or the free-angle slider until the image is perfect. If you want to start over, simply click the "Reset" button.
Q.Is there any risk of my images being saved to a server or leaked?
No, there is absolutely no such risk. This tool uses the browser's native Canvas API, meaning all processing—from selecting to saving—happens entirely inside your device (PC or smartphone). No images are ever sent to an external server, making it safe for private photos.
Q.Can I apply rotation and flipping at the same time?
Yes, you can combine operations. For example, you can rotate the image 90 degrees to the right and then flip it horizontally before saving the final result.
Q.What is the range for free-angle rotation?
You can finely adjust the angle from -180° to 180° in 1-degree increments. This is handy for correcting slight camera tilts or creating angled layouts for design purposes.
Q.Will the resolution or quality degrade when saving?
The output image retains the original resolution. However, for free-angle rotations, the canvas automatically expands to fit the entire image without cropping, which may result in a larger pixel size. Also, saving as JPEG applies compression based on your quality setting.
Q.Does this tool work on smartphones and tablets?
Yes, it works flawlessly on browsers across iPhones, Android smartphones, and iPads. The layout is fully responsive and optimized for any screen size.
Q.What happens to the "margins" created when rotating at free angles?
Rotating at custom angles creates triangular margins in the corners. If you save as PNG, these margins remain transparent. If you save as JPEG, the margins will be filled with white, as JPEG does not support transparency.
Q.When should I choose PNG versus JPEG?
Choose PNG to preserve transparency and prevent quality loss (ideal for illustrations or angled rotations). Choose JPEG for regular photos or SNS uploads, as it significantly reduces file size, though any transparent areas will turn white.
