How to resize an image without losing quality
Most quality loss when resizing comes from poor resampling or upscaling. Here's how to keep images crisp.
Two rules for sharp resizing
- Downscale, don't upscale — enlarging a small image just adds blur.
- Use quality resampling — the resizer uses pica's Lanczos filter, far better than a plain browser resize.
Steps
- Open the image resizer and drop your image.
- Enter the exact width and height you need.
- Choose Cover, Contain or Stretch to control the fit.
- Export — the result stays sharp thanks to high-quality resampling.
