Client-side resizing capability

Because modern browsers are highly optimized for graphics, this process is incredibly fast and secure, using your device's own processing power instead of a remote server.
Common Questions
Does it reduce quality?
It depends. Scaling down images usually preserves quality well. Scaling up images significantly may result in pixelation. You can also adjust the output quality setting.
What formats are supported?
We support resizing JPG, PNG, and WebP images. You can also convert between these formats during the resizing process.
Is it safe?
Yes, completely safe. We use your browser's built-in canvas capabilities to resize images locally. Your photos are never sent to our servers.
Can I batch resize?
Currently, this tool is designed for resizing images one by one to ensure perfect control over dimensions and cropping.
