Rotate Image Online Free
Rotate images 90°, 180°, or any angle. Flip horizontally or vertically. Fix sideways photos from your phone. No software installation, no signup, no watermark.
Why rotate an image?
Common scenarios:
- Phone photos saved sideways. Some older phones store photos in the wrong orientation.
- Scanned documents. Scanners sometimes feed pages at an angle.
- Tilted horizons. Landscape photos taken without a level.
- Text direction. Notes or diagrams written in landscape that should be portrait.
- Mirror correction. Selfies that look "backwards" or flipped product photos.
How to rotate an image
- Open the BG Remove Image Rotator.
- Upload your image (JPG, PNG, WEBP, GIF, or BMP).
- Use the quick-rotate buttons for 90° or 180° rotations.
- Use the fine-angle slider for any angle between -180° and +180°.
- Use the flip buttons if you need to mirror the image.
- Download the result as PNG.
Rotation vs flipping
These are often confused:
- Rotation turns the image around a point. 90° rotation swaps width and height. Fine-angle rotation keeps the canvas size but adds transparent corners.
- Flipping mirrors the image. Horizontal flip reverses left-right. Vertical flip reverses top-bottom.
Does rotating reduce quality?
It depends on the angle:
- 90°, 180°, 270° rotations are lossless — every pixel is preserved exactly. No quality loss.
- Fine-angle rotations require interpolation. Pixels are resampled to land on the new grid. The result is slightly softer, but our high-quality smoothing keeps it sharp.
Repeatedly rotating by small angles will progressively degrade the image. Always start from the original for each rotation.
Fine-angle rotation tips
- Straighten horizons. Find a horizontal line (water, a building edge) and rotate until it's level.
- Expect transparent corners. A rotated image by non-90° angles has triangular gaps at corners. These are transparent in PNG output.
- Crop after rotating. To remove the transparent corners, use the image cropper after rotating.
Flipping explained
Flipping is a mirror. It's useful for:
- Selfie correction. If your selfie looks mirrored (text on your shirt is backwards), flip it horizontally.
- Design consistency. Match the direction of subjects across a set of images.
- Text correction. If a scanned document is mirrored, flip it.
Flipping is always lossless. No quality loss, no canvas change.
Common mistakes
- Rotating the same file multiple times. Each fine-angle rotation adds softening. Start from the original for each adjustment.
- Forgetting to crop transparent corners. A rotated image has transparent corners that look odd when placed on a colored background.
- Rotating when you should flip. If text is backwards but right-side up, you need to flip, not rotate.
- Saving as JPG. JPG doesn't support transparency, so rotated corners become white. Use PNG.
Batch rotation
BG Remove processes one image at a time. If you have many photos to rotate, work through them one by one. Batch processing is on our roadmap.
