Resize runs entirely in your browser using HTML Canvas. Your images are never uploaded to any server.
FAQ
- Are my images uploaded anywhere?
- No. Decoding, scaling, and re-encoding all happen in your browser via FileReader + Canvas. No network requests are made.
- How is the aspect ratio handled?
- When you lock aspect ratio, leaving either width or height at 0 keeps the original size on that axis and computes the other axis automatically.
- Will resizing make the image blurry?
- Resizing always re-samples, so very large enlargements may look soft. We use the browser's built-in high-quality scaling which is fine for typical web output.
