PDFConvertersOnline.comHow to rotate an image
- Choose one photo or a whole batch. The first one is shown as a live preview.
- Press Left 90° or Right 90°, or drag the Any angle slider to straighten a tilted picture.
- Press Rotate and save to download one image, or all of them together as a ZIP.
Why does my photo show up sideways?
Phones and cameras usually store the pixels in the direction the sensor faces and add a small orientation tag that says "show this turned 90°". Your phone's gallery reads the tag, so the photo looks right there. Some websites, older programs and email clients ignore the tag, and the same picture suddenly appears lying on its side.
This tool fixes that for good. It shows the photo the way your browser displays it, lets you turn it as needed, and saves new pixels that are physically upright. The saved file carries no orientation tag, so every app shows it the same way.
Quarter turns and 180°
The three big buttons turn the picture by exact right angles. Width and height swap on a 90° turn, and no part of the image is lost or filled in. Press a button repeatedly to keep turning; the preview and the size under it update straight away. If you change your mind, Undo all changes returns to the original.
Straightening a tilted photo
A horizon that leans by two or three degrees is one of the most common flaws in travel and real-estate photos. Use the Any angle slider, or type a value such as 2.5 or -1.5 into the box next to it. Positive numbers turn clockwise. Once the picture is tilted, the corners no longer line up with the frame, so you get two choices:
| Option | Result |
|---|---|
| Show the whole picture | The canvas grows so nothing is cut off. The empty corner triangles become transparent (PNG, WebP) or take the color you pick. |
| Crop to fill | The image is trimmed to the largest rectangle with the same proportions that has no empty corners. Best for straightened photos. |
Rotating many images at once
Add as many files as you like. The same turn, mirror or angle is applied to every one of them, and a row of small thumbnails shows how each will look before you save. This is handy when a whole set of scans or phone photos came out sideways. The files are processed one after another, so even a large batch won't freeze the page, and you can download them individually or in a single ZIP.
Format and quality
Images are saved in their original format unless you choose another. A JPG is re-saved at 92% quality, which looks the same to the eye but is not a bit-for-bit copy; pick PNG if you need lossless output. iPhone HEIC and AVIF files become JPG. For documents rather than pictures, use Rotate PDF, which turns pages without touching their content.

Frequently asked questions
Does rotating reduce image quality?
A 90° or 180° turn moves pixels without blending them. JPG and WebP files are then saved again at 92% quality, which is normally invisible. Small angles such as 3° do blend neighboring pixels, as in any photo editor.
Which way is Right 90°?
Clockwise: the top of the picture moves to the right side. Left 90° is counter-clockwise.
The photo looks right on my phone but sideways on my computer. Will this help?
Yes. Open it here, turn it until it looks correct and save it. The new file stores upright pixels and no orientation tag, so it looks the same everywhere.
Can I rotate by a custom angle like 45°?
Yes. Drag the slider or type any value from -180 to 180 degrees, including halves such as 12.5.
Do my photos get uploaded?
No. Every file is turned and saved by your own browser. Nothing is sent to a server, which also means large batches don't depend on your connection speed.
