회전및翻转이미지

When should you rotate or flip an image?

Phones and cameras often save photos with the wrong orientation, so they look sideways or upside down on desktop. A free online image rotator lets you quickly rotate photos 90°/180°, fix scanned documents and screenshots, or batch-rotate product images for resumes, slides or online stores.

Horizontal flip is useful for correcting mirror selfies or creating fun effects, while vertical flip is great for reflection effects and creative design layouts.

Best practices for rotating images

For sideways photos, a single 90° clockwise or counter-clockwise rotation is usually enough. For scanned documents, rotate first and then crop away empty borders so the page looks clean. After fixing orientation, you can use the “Compress Image” tool to reduce file size and speed up page loading.
