Public-web utility

Build a bounded image archive

Extract image files referenced by a public HTML page without giving the service access to private networks or unbounded downloads.

Standard HTTP and HTTPS ports only. Redirects and DNS answers are revalidated before every connection.

Explicit boundaries

40 files

Static discovery

Reads image, source-set, inline background, social, and icon URLs from returned HTML.

32 MiB total

Resource limits

Caps the page at 2 MiB and each detected image at 8 MiB before creating the ZIP.

4 formats

Byte-verified files

Accepts JPEG, PNG, GIF, and WebP based on file signatures, not URL claims.

Public only

Restricted egress

Blocks local, private, metadata, link-local, transition, and nonstandard-port targets.

This service does not run a target page's JavaScript, bypass access controls, or guarantee that every visible image can be discovered.
