Key takeaways
- Resize first, compress second—order matters for quality and bytes.
- Keep aspect ratio unless art direction requires crops.
Match your srcset
Generate 1x/2x widths per breakpoint instead of one giant master file.
Pair resized outputs with Image Compress using the same format you ship.
FAQ
Which format after resize?
WebP for photos in modern stacks; PNG when you need crisp UI edges.
Width in secondary field?
Enter target width or WxH; the tool fits inside bounds without upscaling unnecessarily.
