Can I keep the original aspect ratio when resizing?
Yes. Enable "Lock aspect ratio" and changing the width or height automatically adjusts the other dimension to match the original proportions.

Which output formats are supported?
PNG, JPEG, and WebP. JPEG and WebP also let you adjust a quality slider to balance file size against image quality.
Is my image uploaded anywhere?
No. Resizing happens locally using the HTML canvas API — your image is never sent to TripleW Tools or any other server.
