I've used this for years and it must not be supported anymore, failed multiple times. Guess I'm looking for something new. :(

Louis La Bonté2023年3月16日

Works great with the “Remote (online-convert.com)” option, which creates the output file in less than two minutes, but the “Local (no server interaction)” does not seem functional: it indicates that the conversion is ongoing, but never creates an output file (even after a two-hour wait). Also, the suggestion to “add your free API key to the options page” links to https://www.online-convert.com/subscription-details, which does not seem to exist anymore... so, an update would be welcome.

AI product read

Convert and merge multiple files (documents, images, HTML, PDFs) into a single PDF document

Users need to combine files of different formats into one PDF without installing native software or using external web tools; this extension provides both offline local merging and online conversion in a single browser tool.

User clicks extension icon → popup window opens → user adds files via drag-and-drop or file picker → user reorders files via drag handles → user selects conversion method (Local pdf-lib, Local pdfunite, or Remote online-convert.com) → user clicks Convert → extension processes files locally or via API → merged/converted PDF is downloaded via Chrome downloads API

Target users: Users who need to combine multiple PDFs into one document / Users converting various file formats to PDF / Users who prefer browser-based tools over desktop PDF software / Users who value offline/local processing for privacy

The extension bundles large third-party libraries (pdf-lib.esm.js at 1.5MB, Sortable.js at 121KB) which could obscure subtle behavior
Cannot verify actual API rate limits or behavior of the online-convert.com integration at runtime
The embedded Alpine Linux environment (blink WASM emulator) is a novel approach whose full behavior cannot be fully audited statically

Monetization

No paid features detected

The extension itself has no paid features, premium tiers, or billing gates. All three conversion methods are fully functional without payment. The only mention of 'paid' is on the options page noting that online-convert.com (external service) offers paid API keys alongside free ones, but the extension works fine with the built-in shared key or a free user key. A 'Support Development' button links to donations, not feature gating.

Confidence: 90
Payment platform: --
Source: AI / High
Login required: No
Reason: No login or account creation is required. The extension works entirely offline with two local conversion methods (pdf-lib and pdfunite). The remote method uses online-convert.com API with a built-in shared API key; users can optionally provide their own free API key to avoid rate limits, but this is not authentication—it's an optional configuration.
