PDF Inspector
Browser-based PDF-to-Markdown converter with selective OCR and layout-aware structure recovery.
If your PDFs have real structure — multi-column papers, borderless tables, mixed digital-and-scanned pages — FileToMD AI earns its $9.9/month because it targets the parts generic converters mangle. If you just need plain text out of a clean digital PDF, the free tier with its 3-OCR-page cap is enough and you shouldn't pay. The $999 Business Plan only makes sense if you genuinely need 50 shared seats across 3 organizations. Compare CloudConvert or Adobe for raw text dumps; this one is built for structure, not for cloud-level extraction speed.

Skip FileToMD AI if you only need fast plain-text extraction from clean digital PDFs, or if you need scheduled server-side batch jobs, an API, or pre-built connectors into Notion, Confluence, or a vector database.
The free tier stops at 3 OCR pages and 10MB per file, so a single scanned report can push you to $9.9/month before you've evaluated the output quality.
At $9.9/month FileToMD AI undercuts most structured PDF-to-Markdown SaaS tools and sits near the floor of the category, while the $99 one-time Lifetime Plan beats roughly two years of Pro for high-volume individuals. It is meaningfully cheaper than enterprise document-AI platforms priced per page or per seat, but the $999 Business Plan is a poor fit for small teams that only need a handful of seats — at that size, Pro or Lifetime per person is the better spend.

About PDF Inspector
PDF Inspector, now branded FileToMD AI, converts PDFs and other documents into editable Markdown without uploading your files — processing runs entirely in your browser. Drop in a PDF, office file (DOCX, PPTX, XLSX, XLS), web or data document (HTML, CSV, JSON, XML, IPYNB), EPUB, ZIP, or a common image format, and it returns Markdown with headings, paragraphs, lists, links, tables, and sections intact. The workflow is staged: you choose an OCR mode per document — existing text layer only, automatic OCR for pages without usable text, or full-page OCR for an all-image scan — then convert, review the preview, and download an individual .md file or package batch results into a ZIP. Paid plans process up to 30 files at once with a 300MB per-file ceiling. The vendor itself flags reading order in multi-column layouts, merged cells, equations, forms, and charts as the error-prone areas, so review before publishing. The stated audience is developers, researchers, and document-heavy teams building RAG pipelines, knowledge bases, and publishing workflows. The free tier caps at 3 OCR pages and 10MB per file; Pro is $9.9/month; a Lifetime Plan is listed at $99 (from $169); and a Business Plan at $999 (from $1999) adds up to 3 organizations and 50 members. The underlying Rust inspection and text-extraction library is open source on GitHub.
Behind the Verdict
FileToMD AI's core pitch is credible: local browser processing means confidential documents never leave your device, and the three-mode OCR selector (text layer only, automatic, full-page) is a real workflow advantage over one-click converters that force OCR on every document. Structure recovery — headings, paragraphs, lists, links, tables, sections — is the advertised differentiator, and the vendor is unusually candid that multi-column reading order, merged cells, equations, forms, and charts can come out simplified or out of sequence. That honesty is worth something; you can plan a review step around it. Input breadth is a genuine strength: DOCX, PPTX, XLSX, XLS, HTML, CSV, JSON, XML, IPYNB, EPUB, ZIP, and images all funnel into Markdown, so a mixed project folder can be standardized in one pass. Batch processing up to 30 files with ZIP export on paid plans fits ingestion pipelines. The open-source Rust PDF inspection library gives technical buyers a way to inspect and extend the extraction logic rather than trust a black box. Where it doesn't fit: the free tier's 3-OCR-page and 10MB limits will frustrate anyone trialing scanned documents, browser-side processing means large scans run at the mercy of your laptop, and there are no documented pre-built integrations with Notion, Confluence, or vector databases — you handle the plumbing. There is no documented public API or CLI, so automation is browser-driven. For teams whose sole need is fast plain-text extraction from clean digital PDFs, free tools do that job and the paid tiers are overkill.

Real-world workflow fit
Concrete scenarios for the personas PDF Inspector actually fits — and what changes day-one when you adopt it.
Downloads 20 mixed PDFs and spreadsheets, runs automatic OCR on the scanned ones, selects 30-file batch mode on Pro, converts, reviews tables in the preview, and downloads a ZIP of .md files.
Outcome: A folder of chunkable Markdown ready for embedding, with the scanned pages handled without a separate OCR step.
Converts a clean digital paper with the existing text layer, checks reading order in the preview, and exports a single .md for notes.
Outcome: Searchable, quotable notes without spending anything, as long as the source has a usable text layer and stays under 10MB.
Converts confidential contracts in the browser instead of a cloud converter, using full-page OCR only on the image-only pages, and reviews names and figures against the source before exporting.
Outcome: Markdown that never left the device, with a documented manual review step covering the vendor's flagged error-prone areas.
Use Cases
- Convert research papers and multi-column PDFs to Markdown for LLM pipelines
- Extract tables from financial statements and reports into usable Markdown
- Process scanned documents and image-heavy PDFs with selective OCR to save time
- Build knowledge bases by converting documentation PDFs into structured Markdown
- Handle confidential PDFs locally when policy forbids uploading to a cloud converter
- Batch convert sets of PDFs for data ingestion into vector databases
Limitations
- The free tier limits files to 10MB and caps OCR at 3 pages; paid plans raise the file ceiling to 300MB and allow up to 30 files at once.
- Processing runs entirely in the browser, so speed depends on your device and browser environment — large scanned PDFs on low-end hardware will be slow.
- The tool outputs Markdown only, though it accepts many input formats.
- The vendor explicitly warns that multi-column reading order, sidebars, captions, footnotes, merged cells, equations, forms, charts, and decorative layouts may be extracted out of sequence or simplified and require manual editing.
- No pre-built integrations with external systems are documented, so moving output into a knowledge base or vector store is manual work.

Where the pricing makes sense
The company stage and team size where PDF Inspector's pricing actually pencils out — and where peers do it cheaper.
At $9.9/month FileToMD AI undercuts most structured PDF-to-Markdown SaaS tools and sits near the floor of the category, while the $99 one-time Lifetime Plan beats roughly two years of Pro for high-volume individuals. It is meaningfully cheaper than enterprise document-AI platforms priced per page or per seat, but the $999 Business Plan is a poor fit for small teams that only need a handful of seats — at that size, Pro or Lifetime per person is the better spend.
Setup time & first value
How long it actually takes to get something useful out of PDF Inspector — broken out by persona, not the marketing-page minute.
A solo user converting a first PDF: under two minutes to first Markdown, no account required on Free. A developer wiring batch conversion into a RAG pipeline: roughly 30 minutes to reach comfortable output, mostly spent checking table and reading-order fidelity. A team rolling out the Business Plan: budget an hour, since organization and member setup plus a shared review convention add overhead
Switching to or from PDF Inspector
How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.
- →From CloudConvert or Adobe online converters: switch to FileToMD AI when you need structure recovery, local processing, or batch ZIP export rather than a plain text dump.
- →From MarkItDown or other open-source converters: import the same inputs (PDF, DOCX, PPTX, XLSX, HTML) and use the built-in OCR modes plus preview to avoid scripting your own review step.
- →From manual copy-paste out of PDF readers: batch-queue folders and export .md files or a ZIP instead of retyping sections.
- →From an OCR-only tool: drop the separate OCR pass by choosing automatic or full-page OCR inside the same conversion.
- ↗To a cloud page-based OCR service: move there if you need server-side speed or an API for very large scans.
- ↗To a full document-AI platform: move there if you need managed pipelines, entity extraction, and pre-built connectors.
- ↗To a general file converter: move there if you only ever need text and can tolerate weaker structure recovery.
- ↗To a self-hosted pipeline: move there if you want the Rust library embedded directly and don't need the browser UI.
