image_convert

verifiedv0.1

Convert one raster between JPEG, PNG, WebP, AVIF, JXL and HEIC in the browser. Pass image { mime, base64 } (max 12 MiB decoded). source is a filter hint; sniffing governs decode. target is jpeg|png|webp|avif|jxl; quality 1–100 ignored for png. Variant URLs are not a second machine Tool — pass source and target explicitly. Do not upload. WASM stays in-page; abort must stop work.
