Date: 2026-08-08 20:20 Summary: Implemented full pdf-to-markdown tool with pdf.js text extraction, 10-locale i18n, and all gates green.

[question] Implement full pdf-to-markdown in /Users/xuli/vscodeai/onlinefreetools.

Spec

• slug: pdf-to-markdown, category: pdf, #58
• work-tasks ready. Title: "PDF to Markdown — Extract Text for Notes Locally"
• Tech: pdfjs-dist@4.10.38 lazy import (copy pattern from compressPdfPage.ts / pdfToJpgPage.ts). getTextContent per page; group items by approximate y into lines; join with spaces; pages separated by \n\n---\n\n. Download .md. NO OCR — if extracted text (trimmed) is empty, hard fail with clear message.
• Also load pdf-lib only for sample generation OR generate sample text PDF with pdf-lib then extract.
• related: ["markdown-to-html","pdf-to-jpg"] (verify slugs exist in catalog)
• loadSample(): 1-page PDF with Helvetica text "Hello PDF to Markdown sample." → auto convert → Download .md enabled showing that text
• Privacy, 25MB soft warn

Create catalog, icon, pdfToMarkdownPage.ts, 10 i18n independent full keys.

Update 02/03 1b+2b (en,zh,es,ja), inventory #58, README

Gates until green:

npm run merge:tools && npm run coverage:gate -- --slug=pdf-to-markdown --phase=all && npm run build:site && npm run lint:seo && CROSS_TOOL_UPDATE=1 TOOL_SLUG=pdf-to-markdown npm run lint:tool-isolation

No plan/commit. 中文 brief. Chinese comments on functions.

[try to solve] Shipped full pdf-to-markdown:

Core (src/pages/pdfToMarkdownPage.ts)

• Lazy pdfjs-dist@4.10.38; per-page getTextContent, group by y tolerance into lines, join with spaces; pages separated by \n\n---\n\n
• Empty trimmed text hard-fails (err_notext; no OCR)
• pdf-lib builds a 1-page Helvetica sample “Hello PDF to Markdown sample.”; on-enter loadSample() auto-converts and enables Download .md
• 25 MB soft warn; Markdown preview; privacy FAQ

Added/updated

• src/site/tool-catalog.d/pdf-to-markdown.json (category: pdf; related: markdown-to-html, pdf-to-jpg)
• public/icons/tools/pdf-to-markdown.svg
• Ten-locale shards src/site/i18n/tools/pdf-to-markdown/*.ts
• work-tasks/pdf-to-markdown/03-locale-briefs.md 1b+2b rows and search-coverage note
• docs/2026-08-08-tool-inventory-table.md #58 → shipped
• README.md EN/ZH inventory lines

Gates: merge:tools, coverage:gate all, build:site, lint:seo, lint:tool-isolation all passed.
