Guides
Three short pages on the questions people actually get stuck on. Each one points at the tool that does the job, and every number quoted is a measured result rather than an estimate.
- How to compress an image to 20 KB, 50 KB or 100 KB
Which lever to pull first, what each target actually produced on a measured 1.05 MB photograph, and when a number cannot be hit.
- How to resize an image without stretching it
Aspect ratio, the box that fills itself in, why an exact square needs a crop, and what enlarging can and cannot do.
- Signature size for online forms
Where 140 × 60 and 200 × 80 come from, how to crop the paper instead of scaling it, and how to stay under a KB ceiling.
