What our analysis found
Kindle Cloud Reader to PDF – Export Kindle Books showed no malicious code in Extension Auditor's review. It comes from a trusted publisher and was last updated in October 2026.
Analyst notes
The extension does exactly what it advertises: it captures Kindle book content from [domain withheld] and sends it to the publisher's own Cloud Run PDF rendering service ([domain withheld]). All network calls are constrained to the declared host_permissions and go exclusively to the publisher's infrastructure; no Amazon credentials, cookies, or cross-site data are collected. The ML model's pattern hits are fully explained by legitimate functionality: the 1 MB file size comes from bundled npm packages (cssom, boolbase,, zod); fromCharCode hits are binary buffer conversion for data; executeScript injects a named file (), not dynamic code. The third-party risk score corroborates the ML score's weakness: its "high" flags are all recency signals (new extension, new update, low users), not behavioral ones. Publisher reputation is low-risk.
