Software Usage Instructions

Select image files: Click the upload area to choose images, or drag and drop images into the tool. Common formats such as JPG, PNG, WEBP, BMP, and GIF are supported, and you can select multiple images at once.
Set the rotation angle:
- Numeric input: Enter the degree value you want to adjust in the angle input box. Decimal angles are supported.
- Slider adjustment: Drag the slider to quickly preview rotation changes.
- Quick angles: Use buttons such as -90 degrees, -45 degrees, -15 degrees, -1 degree, +1 degree, +15 degrees, +45 degrees, and +90 degrees for quick settings.
Configure canvas and background:
- Canvas mode: Choose expanded canvas to keep the entire image, or choose keep original size to crop the corners after rotation.
- Background fill: Choose transparent, white, black, a custom color, or an approximate edge color.
- Output format: Automatically match the original format, or specify PNG, JPG, or WEBP; transparent backgrounds will use PNG output.
- Output quality: Choose different compression ratios based on your needs.
Save settings: Click “Save Settings” to save the current angle, background, format, and quality parameters for easy reuse next time.
Start processing: After entering the “Process & Download” step, click “Start Processing,” and the tool will process all images according to the current settings.
Preview and download: After processing is complete, you can preview the first 20 results. A single image can be downloaded separately, and multiple images can be packaged and saved by clicking “Download All Results (ZIP)”.

Frequently Asked Questions

A: Common image formats such as JPG, JPEG, PNG, WEBP, BMP, and GIF are supported. The output format can be matched automatically, or you can manually choose PNG, JPG, or WEBP.

A: The angle input supports fine adjustments of 0.1 degrees, and you can enter positive or negative values. Positive values rotate clockwise, while negative values rotate counterclockwise.

A: Expand canvas automatically increases the canvas based on the rotated bounding box to preserve the full image as much as possible; keep original size maintains the original image width and height, and any parts that exceed the boundaries after rotation will be cropped.

A: Choose a transparent background when you need transparent corners; choose a white background for documents, ID photos, or product images; choose an edge-matched color or custom color when you need it to match the tone of the original image.

A: By default, the original file names are kept as much as possible. If the output format changes, the extension will be adjusted accordingly; if duplicate file names occur, a number will be appended to distinguish them.

A: Image rotation uses memory and CPU resources. It is recommended to process large images in batches, reduce the output quality appropriately, and avoid running resource-intensive programs at the same time.

A: Common reasons include corrupted image files, nonstandard formats, oversized images, or insufficient device memory. Try using images in a standard format, or split large batches of files for processing.
