FAQ
- Can I resize to exact pixel dimensions?
- Yes, enter the width and height you need and the image is scaled to match.
- Does it keep the aspect ratio?
- You can lock the ratio so the image is not stretched, or unlock it to set both sides freely.
- Are my images uploaded for resizing?
- No. Resizing happens in your browser with a canvas, so files stay on your device.
- Will enlarging an image make it blurry?
- Scaling up cannot add detail, so big enlargements look soft. Resizing down stays crisp.
- Which formats can I resize?
- PNG, JPG, WebP and other common formats your browser can render.
- Can I resize for social media sizes?
- Yes, just type the pixel dimensions the platform recommends.
