What this tool does
It calculates a bounding box for the rotated rectangle, moves the canvas origin to its center, and draws the image at your chosen angle.
new width = |w cos θ| + |h sin θ|
PNG keeps transparent corners. JPEG fills the expanded corners with your chosen background color.
Supported formats

Tips for better results
- Use small decimal angles to straighten a horizon.
- Select PNG if you need transparent corners.
- A 90° or 180° rotation avoids resampling blur more reliably than arbitrary angles.
FAQ
Does rotate image by custom angle upload my photos?
No. Processing runs in the browser. A pinned library is loaded only when needed, but your selected image bytes are not sent to it or to Callimage.
What happens to image metadata after using this tool?
Canvas-generated image outputs generally omit EXIF and GPS metadata. Keep the original if that information matters.
Why can the result look different from the original?
Decoding, pixel processing, color profiles, and lossy output encoding can change color or fine detail slightly.
Can I use this tool on a phone?
Yes, on a modern mobile browser, although large images may exceed available memory. The tool rejects unusually large inputs before intensive work.
Which files work best with rotate image by custom angle?
PNG, JPEG, and WebP inputs supported by the browser. Animated files are not preserved as animations.
