Frequently Asked Questions

Does this tool upload my image to a server?
No. All image processing happens entirely in your browser using the Canvas API. Your image never leaves your device.
What image formats are supported?
This tool supports JPEG, PNG, WebP, GIF (first frame), and BMP files as input. Output can be PNG (supports transparency), JPEG, or WebP.
How does the transparent background feature work?
The tool removes pixels that are close to a color you pick (default white). You can adjust the tolerance to control how aggressively similar colors are removed. Output must be PNG or WebP to preserve transparency.
Can I crop to a specific aspect ratio?
Yes. You can choose from preset ratios like 1:1 (square), 4:3, 16:9, 3:2, 9:16 or use free-form selection to crop any portion you want.
Is there a file size limit?
There is no hard limit since processing happens in your browser. However, very large images (over 50MP) may be slow depending on your device.

When You Need This

Good to Know

When cropping, follow the rule of thirds — place the subject at the intersection of imaginary lines dividing the image into a 3x3 grid. This creates more visually interesting compositions than centering everything.
