Format catalogue

These are the formats defined by the shipped config.json merged over the built-in defaults — 45 in total. Add, remove or resize any of them by editing config.json.

Dimensions are the target canvas. The source image is fitted into it; it is never upscaled beyond its own resolution, so check the previews when you request something larger than your source.

Output types

Each selected format is rendered into each selected output type.

Type	Alpha	Notes
png	yes	lossless, the safe default
jpg	no	honours the quality slider; flattens transparency
webp	yes	honours the quality slider; smallest at equal quality
ico	yes	only produced for the favicon format; packs 16×16, 32×32 and 48×48 into one file

Naming

<source-basename>_<format-key>.<ext>
<source-basename>_favicon.ico

With variations mode on, the variation label is inserted between the basename and the format key — acme_Grayscale_social.png.

The pixel dimensions are not part of the filename; the format key is what identifies the size.

Notes on specific formats

• favicon is 16×16 in the shipped config.json, but the generated .ico always contains 16, 32 and 48 pixel entries regardless.
• print_a4 (2480×3508) and print_letter (2550×3300) are sized for 300 DPI. They are the two largest canvases in the catalogue and the most expensive to render.
• logo_transparent only makes sense with PNG or WebP output, and with a source that has an alpha channel — or with background removal enabled.
• twitter appears at 1500×500 (the header banner). The 1200×675 card size lives in the built-in defaults and is overridden by config.json; if you want the card, add it back under a different key.
