How to rotate an image 90 or 180 degrees online

Photos taken on a phone in portrait mode are sometimes stored with incorrect EXIF orientation data, appearing sideways in browsers and apps. Other times you need to rotate a graphic for layout purposes. This guide shows how to rotate any image by 90, 180, or 270 degrees using the quickhelp.dev Image Resizer — instant, free, no installation needed.

Step-by-step guide

1. Upload the image: Open quickhelp.dev/image-resizer and upload the sideways or upside-down image.
2. Select rotation angle: Open the Transform tab. Click 90°CW, 180°, or 90°CCW. The canvas preview updates immediately.
3. Download the corrected image: Choose PNG (lossless) or JPEG/WebP and click Download. Orientation is baked into the pixel data — it displays correctly in all apps.

Frequently asked questions

Why does my photo appear rotated even though it looks correct elsewhere?

Cameras embed orientation in EXIF metadata. Some apps respect EXIF; others render raw pixel data. Rotating with this tool bakes the correct orientation into the pixels, fixing it everywhere.

Can I flip an image instead of rotating?

Yes — the Transform tab has separate Flip Horizontal and Flip Vertical buttons to mirror the image.
