Frequently Asked Questions

What's the difference between Max Width and Exact?

Max Width resizes proportionally to fit within the width, preserving aspect ratio. Exact sets precise dimensions which may stretch the image.

Does this reduce image quality?

Resizing doesn't affect quality when downsampling. When upsampling, some quality loss may occur. The quality setting controls compression.

Can I process multiple images at once?

Yes! You can upload multiple images and they'll all be resized according to your settings. Each is processed locally in your browser.

Is my data uploaded anywhere?

No. All processing happens locally in your browser using HTML5 Canvas. No server uploads required.
