How it works
- Fit scale = min(target width ÷ original width, target height ÷ original height). With enlargement off, cap the scale at 1. Exact mode uses the requested dimensions.
Assumptions and limitations
One static JPEG, PNG or WebP at a time, up to 25 MB and 16 million pixels. JPEG/WebP quality is lossy. PNG uses lossless encoding and ignores quality. JPEG replaces transparency with white. File size may increase. Re-encoding can change metadata and color appearance; keep your original.
