Need to fix a sideways photo or change the direction of a picture? The ZeroKB Rotate Image Online tool helps you rotate images in a few simple steps. You can work with JPG, JPEG, PNG and WEBP files, choose a preset angle or enter a custom angle, flip the image horizontally or vertically, and save the result in a supported format. It is useful for correcting photos taken in the wrong orientation, preparing pictures for documents, and adjusting images before sharing them online.

How to Rotate an Image Online

Start by selecting an image from your phone, tablet or computer. Once the preview appears, choose the rotation you need. The preset controls let you select 0°, 90°, 180° or 270°, while the Custom Angle field can be used for another angle between -360° and 360°. The preview updates so you can check the direction before creating the output file.

Rotate, Straighten and Flip Your Picture

Use the rotation controls when a photo is sideways or upside down. If the picture is mirrored, choose Horizontal Flip or Vertical Flip. These options are helpful for correcting scanned pictures, product images, screenshots and other graphics. For cropping or changing the dimensions after rotation, you can continue with the Crop Image tool or the Resize Image tool.

Choose an Output Format and Image Quality

The tool can keep the original image format or export the result as JPG, PNG or WEBP. JPG is commonly used for photographs and smaller image files. PNG is often suitable for graphics that need lossless image data or transparency. WEBP can be useful for web images when your target platform supports it. Select the format that suits your intended use, then adjust the quality setting when the selected output format supports quality-based compression.

Optional Target File Size

If you have a size limit, enter a target file size before downloading. Target-size results can vary depending on the original image, its dimensions and the selected output format. PNG files do not respond to the quality setting in the same way as JPG or WEBP, so an exact target size cannot be guaranteed for every image. If the file is still too large, try the Compress Image tool or use a suitable format for your needs.

Browser-Based Image Processing

The rotation process runs in your browser and does not require you to upload the image to a processing server. Choose a file you have permission to use, keep a copy of the original if it is important, and check the preview before downloading. Very large images may take longer to process and can use more memory on your device. If processing fails, try a smaller image or another supported file.
