How much can I compress my images?

Depending on the image, you can reduce file sizes by 50-90% while maintaining good visual quality. WebP format typically gives the best compression.

Is image quality affected by compression?

Minimal quality loss. WebGati uses smart lossy and lossless algorithms that preserve visual quality while reducing file size significantly.

What image formats are supported?

JPEG, PNG, WebP, GIF, BMP, and SVG files are all supported for input and output.

Can I compress multiple images at once?

Yes. The tool supports batch processing — upload multiple images and optimize them all simultaneously.

Are my images uploaded to WebGati servers?

No. Image optimization happens entirely in your browser using local processing. Your images never leave your device.

Can I change the format when compressing?

Yes. You can convert between JPEG, PNG, and WebP formats while compressing.

Is there a file size limit for images?

No enforced limit. Most images process instantly; very large files (50MB+) may take a few seconds.

Why should I use WebP instead of JPEG?

WebP files are typically 25-35% smaller than equivalent JPEG files with similar quality, making them ideal for web use.

Can I use this on mobile to compress photos?

Yes. The tool works on iPhone and Android browsers, allowing you to compress photos before sharing.
