Original, tested explanations for image formats and upload workflows. Every guide names its author, evidence, method, sources, and limitations.
Measured
Reports a measurement produced by the PixelConvert repository’s own deterministic test corpus. Byte sizes, dimensions, encoder settings, and the capture script are named, and the test files are downloadable.
Reference
Explains published specifications, standards, or platform rules with inline citations. It makes no in-house measurement claim, and the article says so in place of a methodology block.
Reference
Which conversions keep a transparent background and which destroy it, how to convert PNG to JPG when you have no choice, and how to get transparency back from a WebP.
