Why does my photo show sideways?
Phones and cameras often save pixels in the sensor's landscape layout and add an EXIF “Orientation” tag that tells software how to turn the picture. Your gallery app reads that tag, so the photo looks upright there. Some upload forms, older programs and websites ignore it, and the same file appears on its side.
This tool fixes the problem at the source. It applies the tag when it opens the file, lets you turn the image further, and saves plain upright pixels with no tag left to be misread. Camera details and GPS location are dropped too. If you only want to strip metadata, use Remove EXIF Data.
Rotate or flip?
Rotating turns the whole picture around its centre without mirroring anything. Flipping creates a mirror image: horizontal swaps left and right, vertical swaps top and bottom. Reversed lettering in a selfie needs a horizontal flip, not a rotation. Flips apply to the result you see in the preview, so they behave the same at any angle.
Straightening a tilted photo
Use the slider for a rough angle, then type an exact value such as 2.5 or −1.8. Positive numbers turn clockwise, negative numbers anticlockwise. Line up a horizon, door frame or page edge with the edge of the preview.
Any angle that is not a multiple of 90° leaves gaps at the corners, so you choose how to handle them:
- Expand canvas keeps every pixel and makes the image slightly larger. Corners are transparent in PNG and WebP, or your fill colour in JPG.
- Crop to fill keeps the original width and height by enlarging the photo just enough to hide the corners, trimming a thin border.
Crop to fill usually suits product shots and scans. For logos or artwork, expand the canvas and finish with Image Crop.
Does rotating reduce image quality?
A 90°, 180° or 270° turn is geometrically perfect: every pixel moves without being blended. Free angles need new pixel values interpolated between the old ones, which softens fine detail very slightly. The tool always works from your original file, so changing the angle several times does not add up.
The format matters too. PNG saves pixels exactly. JPG and WebP are compressed again, and the quality slider controls how much; 92% is close to the original, while 95–100% suits print or archiving. To make the file smaller for email or a web form, run it through the Image Compressor.
For a stack of upside-down scans, add them all at once. Every setting applies to the batch, the preview shows the thumbnail you select, and the ZIP keeps each original name plus “-rotated”.
