What is Image Rotator?

The Image Rotator turns images by preset angles (90, 180, 270 degrees) or any custom angle you specify. Fix a sideways photo or straighten a crooked scan.

Drop a photo and any EXIF orientation flag is read and straightened automatically, so a sideways phone shot lands upright before you touch a control. Tap the quick-angle chips (15, 30, 45 either way) to jump straight to an exact tilt, or drag the slider for anything in between. By default the canvas grows to hold the full rotated image so nothing is cut off, but for off-axis angles you can switch to Crop (keep the original size and let the corners spill over) or Fit inside (shrink the rotated image to stay within the original frame). PNG keeps the corners transparent; JPEG and WebP can re-encode at a quality you set with the slider, and JPEG needs a solid fill since it can't store transparency. When you're done, copy the result straight to your clipboard or download it. Flip Horizontal and Flip Vertical mirror the image after rotating, and batch mode applies the same rotation and flips to up to 30 images at once, packaged as a ZIP.

How to use

1. Step 1 — Upload your image by dragging it onto the canvas or clicking the upload area.
2. Step 2 — Use the quick-rotate buttons for 90° increments, or drag the angle slider for precise custom rotation between -180° and 180°.
3. Step 3 — Preview the rotated and flipped result, then pick an output format: PNG for transparent corners, or JPEG / WebP with a quality slider for smaller files. For off-axis angles, pick how the canvas is framed (expand, crop, or fit inside) before you download.

When to use

• Straightening a scanned page or photo that came out a few degrees off-axis.
• Turning a portrait phone photo to landscape, or vice versa, in one click.
• Tilting an image slightly for a stylised design layout or moodboard composition.

Result

A scanned document is tilted 3 degrees clockwise. Enter -3 in the custom angle to straighten it perfectly. Choose PNG to keep transparent corners, or pick JPEG and a fill color when you need a flat-background image.

FAQ

Why does the rotated image have transparent corners?

Rotating a rectangle by any angle other than 90, 180, or 270 leaves diagonal gaps at the corners. The PNG output keeps those gaps transparent by default, so you can layer the result on any background. Turn on the fill color option to paint the corners instead.

Does rotation reduce image quality?

Multiples of 90 degrees are lossless — pixels are simply swapped. Other angles need interpolation, which softens fine detail slightly because each output pixel is sampled from a blend of nearby source pixels. The effect is usually invisible at a glance.

What's the difference between a quick 90 degree rotation and using the slider?

The 90, 180, and 270 buttons just swap pixels around, so the image stays exactly as sharp as the source. Everything else — the slider and the 15, 30, 45 quick-angle chips — turns the image to an off-axis angle, which resamples the pixels and softens fine detail a touch. That's fine for photos; for tiny text or sharp diagrams the right-angle buttons keep things crispest.

Can I rotate by a fractional angle, like 3.5 degrees?

The slider snaps to whole degrees. For a tilted scan, 1 or 2 degree adjustments usually fix it — eye-balling at sub-degree precision is rarely needed because the human eye doesn't reliably detect tilts smaller than about half a degree.

Can I save the rotated image as JPEG?

Yes. Pick JPEG in the output format selector; a solid background fill is then required because JPEG cannot store transparency. The default fill is white, but you can pick any color with the swatch.
