How to Rotate an Image Online by 90° or 180°
Rotate images 90° clockwise, 90° counterclockwise or 180° in your browser. Learn about batch processing, JPEG quality and checking the result.
A sideways photo or upside-down scan often needs a quarter-turn rather than a full editor. ConverterTo provides three rotation choices: 90° clockwise, 180°, and 90° counterclockwise (270° clockwise).
Rotate your images
- Open the Image Rotator.
- Browse for images or drag them into the file area. You can select multiple files.
- Choose a rotation from the settings.
- Start conversion, then download and open the results.
The same angle is applied to every image in the batch. If different photos need different corrections, process them in separate batches. The tool does not offer an arbitrary angle such as 2° for straightening a slightly tilted scan.
Processing takes place in your browser; image files are not sent to a conversion server. Large images and batches use device memory, so start with a few files on a phone or a device with limited memory.
Does rotation affect quality?
This tool draws the image onto a canvas and encodes a new image. JPEG output is re-encoded, so the operation is not lossless. Keep your original and avoid repeatedly rotating an already processed JPEG.
A 90° or 270° rotation swaps width and height; 180° keeps the dimensions. The image is not resized to a smaller resolution by the rotation itself. File size can still change because the output is newly encoded.
If you need a JPEG workflow that guarantees lossless rotation, choose a tool explicitly designed for that operation. This browser tool does not provide that guarantee.
Orientation and metadata
Some images include an EXIF orientation tag. The browser decodes the image, the selected rotation is applied to the displayed pixels, and a new file is written. Original metadata is not preserved by this workflow.
Check one result before processing a whole batch: a photo that already appears upright may not need any additional rotation. The tool does not automatically diagnose which direction is correct.
Troubleshooting
It still looks wrong. Open the downloaded file rather than an old thumbnail. If needed, restart from the original and choose another angle.
I need a mirror image. Use Image Flip; rotation and flipping perform different operations.
The tab becomes slow. Try fewer or smaller images. Keep the tab open until downloads finish, and verify the saved copies before deleting anything.
