Rotate Image

Quick answer
A photo shot with the phone held sideways straightens out in one click here, and the fine-angle slider next to the 90-degree buttons levels a horizon that is a few degrees off.
What it does
What the rotate image does
The tool offers two ways to turn an image: quick 90, 180 and 270-degree buttons for a full quarter-turn, and a slider that turns it in whole degrees, up to 180 either way, for straightening a tilted horizon or a scanned document that went in askew. Both draw the rotated result onto a canvas, so what you see in the preview is the exact pixel grid that gets exported.
Most sideways photos are not actually stored sideways. A phone camera sensor is fixed in one orientation, so instead of rotating every pixel at capture, the camera writes a small EXIF field called Orientation, a number from 1 to 8, into the file header, and that flag tells a viewer to rotate or mirror the image before showing it. Phones do this because rotating a full-resolution frame in hardware on every shot would slow down burst mode and cost battery; flipping a tag is instant.
The trouble is that not every piece of software reads that tag. Some upload forms, CMS pipelines and older viewers ignore Orientation and just show the raw pixel grid, which is why a photo that looks upright on your phone appears rotated ninety degrees once it lands on a website. Rotating here bakes the correct orientation into the pixels themselves and clears the tag, so the result displays correctly everywhere, including software that never read EXIF in the first place.
Step by step
How to use it
- 01
Add the photo
Drop the file in or browse for it. A thumbnail appears with the current orientation and a rule-of-thirds grid overlay.
- 02
Choose a quick turn or drag the slider
Tap 90, 180 or 270 for a quarter-turn, or drag the fine-angle slider to level a tilted horizon by a degree or two.
- 03
Check the edges
A fine rotation leaves triangular gaps at the corners; decide whether to crop them or keep the canvas as-is with a fill color.
- 04
Export
Download as the original format or switch to PNG if you plan to edit further and want to avoid another lossy pass.
Your images never leave your device
A site inspector documenting a structural defect, or a landlord photographing a unit before a tenant moves in, often ends up with a stack of sideways photos straight off a phone. Because the rotation happens on the canvas in your own browser, none of that documentation is transmitted anywhere to get straightened out; the file never leaves the device it was opened on.

Format and quality tips
- 01
Rotate once, not repeatedly
Every time a JPEG is decoded and re-encoded it loses a little more detail to quantization, a compounding effect called generation loss. If you need multiple 90-degree turns, do them in one pass here rather than rotating, saving, reopening and rotating again across several tools.
- 02
Why truly lossless 90-degree rotation is rare
JPEG stores pixels in 8x8 blocks called MCUs, and a tool that manipulates those blocks directly, such as jpegtran, can spin an image by 90 degrees without touching pixel values at all. That trick only works cleanly when width and height are exact multiples of 8; any leftover partial block forces a re-encode anyway. A canvas-based rotator like this one always redraws the image, more flexible for arbitrary angles but a fresh compression pass on export.

Frequently asked questions
01Why does my photo look upright on my phone but sideways online?
Your phone is reading an EXIF Orientation tag that tells it how to display the raw pixels, but the site you uploaded to is ignoring that tag and showing the unrotated grid. Rotating here writes the correct orientation directly into the pixels so the tag no longer matters.
02Does rotating a JPEG by 90 degrees lose quality?
A canvas rotation redraws and re-encodes the image, so a small amount of quality is lost, the same as any re-save. A dedicated lossless rotator can avoid this for dimensions divisible by 8, but this tool trades that narrow case for the ability to rotate by any angle.
03Can I rotate by an exact custom angle like 3 degrees?
Yes, in whole degrees. The fine-angle slider moves one degree at a time from -180 to 180, which is precise enough for leveling a horizon or straightening a scan. Fractions of a degree, such as 3.5, are not supported.
04What happens to the corners when I straighten a tilted photo?
Rotating by anything other than a multiple of 90 degrees leaves triangular gaps at the four corners, which you can crop out or leave filled with a background color.
05Will the rotated file keep its EXIF data?
No. The image is redrawn from its pixels and saved fresh, so camera model, timestamp and GPS location are not carried over, and the Orientation flag goes with them, which is fine because the pixels are now physically correct. Keep the original file if you need that metadata.
06Is there a limit to how many photos I can rotate at once?
No server-side limit applies since nothing uploads, but large batches are bounded only by your device memory and browser tab limits.
