Accstall Cookie Converter

Browser-only cookie format converter. Paste a dump, auto-detect the source, inspect expiry flags, and emit one of nine targets.

Live demo: accstall.com/en/tools/cookie-converter

Privacy contract

1. Runs in the browser. Parse and convert in JavaScript. The paste is not sent to a backend, logged, or written to localStorage / sessionStorage / IndexedDB.
2. No inject. This tool never calls document.cookie, never talks to a browser profile API, and never opens a target site with the dump.
3. Downloads are plaintext. Delete them after import.
4. Size cap: 512 KiB. Over cap → empty result + “too large”.
5. The Cookie request-header target is lossy (name/value only).

AdsPower vs GoLogin:

• AdsPower uses expires (0 if session). No expirationDate, no url.
• GoLogin requires url and uses expirationDate.

Mixing those fields breaks imports.

Run locally

Open index.html in a browser. No build step.
