FORMAL MATHEMATICAL SPECIFICATION: WHATWG srcset MAX-CANDIDATE & RFC 2397 BASE64 PAYLOAD LAW
srcset & RFC 2397 Base64 Payload Law:
Selects candidate u_i maximizing pixel width w_i or density d_i × W_0, and computes exact decoded binary bytes B from Base64 character length L and padding P (0, 1, 2) (MathML Standard):

PNG Extractor and Website Logo Downloader isolates lossless alpha-channel PNGs, serializes inline W3C SVG 2.0 brand vectors, and rewrites compressed CDN thumbnails to ?name=orig (.jpg_orig) in under 15ms.Client-side JSZip and OffscreenCanvas pipelines transcode WebP/AVIF streams into lossless PNG or 92%-quality JPEG and bundle 100+ extracted images into a single downloadable .zip archive in <400ms with zero server storage. If a webpage serves brand logos as inline <svg> markup or wraps transparent product cutouts inside IETF RFC 9649 WebP containers, then our format-specific extractor reconstructs standalone .svg, .png, and .jpg files with 100% pixel fidelity.

Brand Identity & Vector SVG Design Systems (xmlns Serializer)
Serializes inline <svg> DOM nodes, injects missing xmlns='http://www.w3.org/2000/svg' and viewBox bounds, and extracts CSS background-image sprites.
Cloudflare-Protected & Auth Portals (RFC 2397 Base64 + DOM)
Parses pasted DevTools outerHTML and CSS stylesheets in volatile browser memory via DOMParser(), bypassing Cloudflare 403/CORS restrictions and decoding RFC 2397 Base64 streams.
How Does the PNG, .jpg_orig & SVG Website Logo Extractor Reconstruct Lossless Master Files?
The PNG, .jpg_orig, and SVG Logo Extractor filters discovered webpage assets by MIME signature while rewriting CDN resize tokens (_400x400, -300x200, ?name=small) to recover 100% native resolution. If an inline <svg> logo lacks an XML namespace header, then the serializer injects xmlns='http://www.w3.org/2000/svg' and exports a valid vector file.
Brand designers searching for a website logo downloader or png extractor frequently encounter inline SVG paths without external .svg URLs, or transparent cutouts compressed into Next.js/Cloudflare WebP responses.
Using the MIME filter pills (JPG / .JPG_ORIG, PNG ISO 15948, INLINE SVG 2.0, WEBP / AVIF) and the HTML5 Canvas transcoder, you can isolate vector emblems (24mm to 350mm viewBox) or convert any WebP graphic into a 32-bit RGBA PNG.

How do I download a website logo as an SVG or transparent PNG?
Enter the website URL above, click 'Extract 10 Vectors', filter by 'INLINE SVG 2.0' or 'PNG', and click 'Download' (or 'PNG' to rasterize an SVG into a high-resolution transparent PNG).
What is .jpg_orig and how does the extractor recover it?
Social and e-commerce CDNs append parameters like ?name=small or _400x400.jpg to serve downscaled thumbnails. Our un-cropper rewrites those parameters to ?name=orig (.jpg_orig) and strips dimension suffixes to fetch the original studio upload.
