No adjustments made — the result will match the original orientation
Before/after preview side by side. Click the preview button in the file list to switch images
Upload your images and click “Rotate left/right 90°” or “Rotate 180°” to fix the overall orientation, drag the fine-angle slider to level a tilted horizon, and flip horizontally or vertically with one click. Batch-process multiple photos that share the same orientation issue at once, and get a straightened result in just seconds.
Rotation and flipping happen entirely locally in your browser — the image never passes through any server
Not limited to 90° increments — drag a slider to correct even a slightly tilted horizon

Common Use Cases
Whether it's a sideways phone photo or a tilted scanned document, picking the right adjustment method straightens it out in one pass.
Your photo library often has a few photos with the wrong orientation that end up sideways or upside down once transferred to a computer. Upload them and click rotate once — the whole batch gets straightened out together.
Phone photos of an ID card, receipt, or supporting document often come out tilted at the angle they were shot. Straighten and fine-tune the angle first, then pair with cropping to remove extra background, ready for merging into a PDF for submission.
Front-camera selfies and photos of a whiteboard or document taken with a mirror-reversed camera often come out horizontally flipped, with text and patterns reversed. A single click on horizontal flip fixes it back to the correct orientation, no need to retake the shot.
Adjustment Methods
All three methods can be combined — picking the right one gets it straightened in one pass, no repeated attempts needed.
| Method | How to Use | Affects Quality? | Best For |
|---|---|---|---|
| Quick rotate 90° / 180° | Click “Rotate left 90°” or “Rotate right 90°” — click repeatedly to stack up to 180°/270° | Pixels are rearranged as a whole grid with no interpolation needed, so sharpness is virtually unaffected | The overall orientation from a phone photo is wrong (landscape shows as portrait, or the image is upside down) |
| Fine-angle adjustment | Drag the -45° to 45° angle slider to fine-tune until the image is level | Requires interpolation to recalculate pixels — the larger the angle, the more noticeable the quality loss, and the corners automatically expand with blank space | A tilted horizon, or the phone wasn't held level when shooting |
| Horizontal / vertical flip | Click the horizontal or vertical flip button — can be combined with rotation | Only mirrors pixel positions, produces no blur, and doesn't affect sharpness | A selfie or photographed document that came out mirror-reversed and needs correcting back to normal |
The three methods can be combined — for example, first click “Rotate right 90°” to turn a landscape image into portrait, then use the fine-angle slider to level the horizon. In batch mode, the same settings apply to every image, which is ideal for straightening a whole set of photos that share the same orientation issue at once.
How to Use
No software to install — everything happens right in the browser.
Click to select or drag your images into the page — select multiple at once. Supports JPG, PNG, WebP and GIF, up to 20MB each.
Click “Rotate left 90°” or “Rotate right 90°” to fix the overall orientation, drag the fine-angle slider to level a tilted horizon, and click horizontal or vertical flip for mirroring.
Click start — the images are redrawn locally in your browser according to your current settings, with the canvas automatically expanding to fit the rotated result without cropping any content.
Download individually or click download all to save every straightened image at once.
Technical Notes
Using the browser's native Canvas rotation, mirroring, and drawing capability, the transform is applied and re-encoded directly on your device — the whole process never touches a server, and both the original and processed images stay only in your local memory.
When you use fine-angle adjustment or a non-right-angle rotation, the canvas first calculates the smallest bounding rectangle that can fully contain the entire rotated image, then draws the image centered within that expanded canvas — the extra blank space around the edges is filled automatically (white for JPG, transparent for PNG). This ensures no content is ever cropped, at the cost of the image's overall dimensions becoming somewhat larger.
FAQ
Right-angle rotations like left/right 90° or 180° simply rearrange the pixels along a grid with no interpolation required, so they don't introduce blur on their own — only a small, normal loss from re-encoding to JPG, similar to compression. “Fine-angle adjustment,” since it's not a multiple of 90°, requires interpolating pixels, and the larger the angle, the more noticeable the loss in detail — it's best used only for small corrections like leveling a horizon (within about ±10°); if a photo is tilted at a much larger angle, it's better to retake it.
That's because phones usually don't actually rotate the pixels when you take a photo — instead, they record the shooting orientation as a tag called EXIF Orientation, which photo viewers are supposed to read and use to auto-correct the display. Different software and systems support this tag to varying degrees, so apps that don't support it will show the photo tilted. This tool reads images using the browser's built-in decoding capability, which automatically corrects the orientation based on the EXIF tag before displaying or processing it — and the exported result has the pixels themselves physically rearranged, no longer relying on the EXIF tag, so it looks correct in any software.
It's done entirely in your current device's browser, using the browser's built-in Canvas drawing capability to generate the rotated or flipped image directly — the original is never uploaded to any server.
Yes — in batch mode, every image uses the same rotation angle, fine-tune angle, and flip settings, which is ideal for straightening a whole batch of photos that share the same orientation issue at once (for example, a set of photos from the same shoot that all came out sideways). If different images need different angles, it's best to process them in separate batches, or finish one batch before adjusting the settings for the next.
Rotating left/right 90° swaps the width and height (landscape becomes portrait), while rotating 180° keeps them the same. When fine-angle adjustment is used, the canvas automatically expands as needed to fully contain the tilted result — the extra blank space around the edges is filled white for JPG or kept transparent for PNG, so no original content is ever cropped. If you'd rather not have that blank border, use the Crop Image tool afterward to trim it off.
Rotating/flipping essentially redraws and re-encodes the image: PNG's transparency channel is preserved, but if the original has transparent areas and is detected as needing JPG encoding, those areas will be filled with a white background. The original's EXIF capture parameters, location, and other metadata are not preserved after re-encoding — if you need to view or remove EXIF data specifically, use the “EXIF Viewer/Remover” tool.
