Resize images to any width and height while preserving aspect ratio. Leave one dimension blank to scale proportionally. The output keeps your original format — PNG stays PNG, WebP stays WebP — and never upscales beyond the source resolution.

Common questions
Will the aspect ratio be preserved?+
Yes — we use inside-fit, so the longest side hits your target dimension and the other scales proportionally.
Can I make my image larger?+
No upscaling. We never enlarge beyond the source resolution to avoid blur.
Does the format change?+
No. PNG → PNG, WebP → WebP, JPEG → JPEG.
What is the maximum dimension?+
10,000 pixels per side. Anything larger is capped automatically.
