Resize in PixelsAnswers to common questions about pixel-based image resizing.
Pixel resizing changes the exact width and height of the image grid. It determines how many pixels the file contains, which affects on-screen size and file weight. Print size depends on DPI, not pixel count alone.
Start with the display area in your layout. For high-DPI screens, export at 2x to keep images sharp, then let CSS scale down. This approach keeps detail while controlling file size.
Not if you keep the aspect ratio locked. The tool updates the other dimension automatically, so the image keeps its original proportions and avoids distortion.
Upscaling adds pixels that were not in the original, so images can look softer. For the best quality, start with a larger source or only downscale.
If your design targets high-DPI devices, exporting at 2x or 3x keeps images crisp. You can still set the final display size in CSS while serving the larger file.
Use JPG for photos, PNG for transparency or crisp graphics, and WebP for smaller files with good quality. Test formats to see which looks best for your content.
