Rotate Image
100% private — runs on your device, never uploaded. Works offline once loaded.
Rotate any JPG, PNG or WebP image clockwise, counter-clockwise or upside down. Everything runs locally in your browser — your image is never uploaded.
Why a photo ends up sideways in the first place
Most rotated photos aren't actually rotated in the pixel data at all — they're stored upright but carry an EXIF orientation tag telling the viewer to display them turned. Phone cameras write this tag depending on how you held the device when you shot the photo. The trouble starts when you upload that file somewhere that ignores EXIF (many web forms, older CMS platforms, some email clients), and suddenly your portrait photo displays sideways to everyone else. Rotating the image for real, so the pixels themselves are turned and saved that way, fixes this permanently regardless of what the next viewer does with orientation metadata.
How 90°, 180° and 270° rotation actually works
A 90° or 270° rotation maps every pixel at position (x, y) to a new position based on swapping and inverting the width/height axes — which is why a rotated 4000×3000 photo comes out as 3000×4000. A 180° rotation just flips both axes, so width and height stay the same. Because these are all multiples of 90°, no pixel interpolation or blending is needed: every original pixel lands exactly on a new grid position with no blurring, unlike an arbitrary-angle rotation (say, straightening a crooked horizon by 3°) which has to estimate in-between colour values and softens the image slightly.
Common situations this solves
Scanned documents from a flatbed or feeder scanner routinely come out landscape when the page was fed sideways, or upside-down when the original was stacked wrong — rotating before you file or email the scan saves the next person from tilting their head. Product photos shot handheld sometimes get saved with the wrong orientation baked in when exported from certain apps, which then displays incorrectly once it hits a website or marketplace listing that strips EXIF data on upload.
- Portrait-mode phone photos that appear sideways after upload to a site that ignores EXIF
- Scanned PDFs or receipts fed into the scanner the wrong way
- Screenshots taken on a rotated monitor
- Camera photos where the orientation sensor didn't register the angle correctly
A quick tip on batching
If you have a whole folder of photos rotated the same wrong way — a common outcome after importing from an old digital camera — it's faster to rotate them all by the same fixed angle rather than opening each one individually, since a consistent rotation direction usually applies to an entire shooting session.
Frequently asked questions
Will rotating reduce quality?
No — rotating by 90° increments is lossless and keeps your image sharp.
Are my images uploaded?
No. Rotation happens on your device and your files stay private.
Will rotating reduce image quality?
No. Rotating by 90°, 180° or 270° is a pure pixel-remapping operation with no interpolation, so the result is pixel-for-pixel as sharp as the original — this is different from straightening at an arbitrary angle, which does soften the image slightly.
Why do the width and height swap after I rotate?
A 90° or 270° rotation turns the image on its side, so what was the width becomes the height and vice versa. A 180° rotation keeps the original dimensions since it flips the image in place without turning the axes.
Does rotating fix EXIF orientation issues permanently?
Yes — rotating actually rewrites the pixel grid instead of just changing a metadata tag, so the image will display correctly everywhere, including on systems and apps that ignore EXIF orientation data entirely.
Can I rotate PNG images with transparency?
Yes, transparent areas in a PNG are preserved exactly through rotation since the alpha channel is rotated along with the colour data.
Are my images uploaded to a server to be rotated?
No — the rotation is performed by your browser directly on your device, so the original file never leaves your computer.
What file formats can I rotate?
JPG, PNG and WebP are all supported; the tool preserves the original format on export so a JPG stays a JPG and a PNG stays a PNG.
