How to use Change Image Aspect Ratio
1. Select your input
Choose a JPG, PNG or WebP image from your device using the file button or supported drop area. The standard file picker accepts browser-readable images up to 25 MB; decoding support depends on the file and browser.
2. Understand the settings
Choose a listed ratio such as 1:1, 16:9 or 9:16. Crop to fill removes overflow; Fit with padding keeps the full picture and adds a chosen colour.
3. Process and review
Select the ratio and adjustment method, set padding colour when using Fit, process and inspect the frame.
4. Save your result
Use the result’s Download control after processing. Keep your original separately and inspect the exported copy at its intended display size; the preview alone is not the file you will share.
Supported formats
Input: browser-readable images, normally JPG, PNG and WebP, up to 25 MB. Output controls include the shown Keep, JPG, PNG or WebP choices. Keep preserves a supported source encoding choice, not byte-for-byte original data; animation is not preserved.
When to use this tool
Change the shape of an image using the available crop or padding choices. Aspect ratio describes shape, independently of the file size in KB.
What to check in the result
Cropping removes outer detail; padding keeps more of the image but adds space. Review where the subject sits inside the final canvas.
Continue with Resize Image when that step fits your workflow.
A practical example
Put a landscape photo into a square with padding when you want to keep both people at the edges.
Capabilities and limitations
The available ratios are the options shown in the tool. Cropping can remove content; fitting adds visible margins.
Troubleshooting
If the subject is cut off, switch from crop to padding or choose a different listed ratio. Preview both edges before saving.
Processing and privacy
Image pixels are processed on your device. Loading the website and processing assets still uses a network connection, and hosting may receive normal request information. Keep original files backed up.

Should I crop or pad?
Crop removes edge content; padding retains the picture and adds surrounding canvas to reach the chosen shape.
