FAQ
- Does resizing reduce quality? Scaling down is generally imperceptible. Scaling up may introduce slight softness, as the tool cannot invent detail that wasn't in the original.
- What formats are supported? JPG, PNG, and WEBP — both as input and output.
- Is my file uploaded anywhere? No — all resizing happens in your browser using the canvas API.
