Frequently asked questions
Is my image uploaded to a server?
No. The image is processed entirely in your browser using the Canvas API — it never leaves your device, is never uploaded, and is never stored. That makes it completely private and very fast.
How do I resize an image without losing quality?
Resizing smaller keeps quality well; enlarging beyond the original size always softens detail because pixels have to be invented. Keep the aspect ratio locked, and for photos export as JPG or WebP. This tool uses high-quality smoothing when it redraws.
What image formats can I resize?
You can resize PNG, JPG/JPEG, WebP, GIF, and BMP images. Animated GIFs are resized to a single still frame, since the browser canvas exports one frame.
