Best PDF to Markdown Converter for Obsidian in 2025

Why Convert PDFs for Obsidian?

Obsidian is the ultimate tool for building a second brain, but it doesn't handle PDFs natively. If you're a researcher, student, or knowledge worker, you're drowning in PDF documents that need to be searchable, linkable, and integrated into your Obsidian vault.

Converting PDFs to Markdown solves this by:

• Making content searchable within Obsidian
• Enabling bidirectional linking between notes and PDF content
• Allowing you to annotate and remix PDF content
• Creating a unified knowledge base in plain text

Pro Tips for Obsidian + PDF Workflow

1. Create a "Sources" Folder

Organize converted PDFs in a dedicated folder:

vault/ sources/ papers/ research-paper-1.md research-paper-2.md books/ book-chapter-1.md

2. Use Frontmatter for Metadata

Add YAML frontmatter to track source information:

--- title: Research Paper Title author: Dr. Jane Smith date: 2024-01-15 tags: [research, ai, pdf] source: https://arxiv.org/paper123 ---

3. Create an Index Note

Build a "Map of Content" (MOC) that links to all your converted PDFs:

# Research Papers MOC ## AI & Machine Learning - [[research-paper-1]] - [[research-paper-2]] ## Productivity - [[book-chapter-1]]

4. Use Tags for Organization

Tag converted notes by topic, project, or status:

• #source/pdf - Mark as converted from PDF
• #status/to-review - Flag for further reading
• #project/thesis - Link to specific projects

Common Issues & Solutions

Issue: Tables Not Converting Properly

Solution: BlazeDocs preserves 95%+ of tables. If a table is complex, you may need to manually adjust a few cells. Simpler than retyping the entire table!

Issue: Scanned PDFs Not Converting

Solution: Make sure you're using a tool with OCR support. BlazeDocs uses Mistral AI's Pixtral model for accurate text extraction from images.

Issue: Links Not Preserved

Solution: Most converters (including BlazeDocs) preserve hyperlinks in Markdown format: [link text](https://example.com)

Alternative Methods (Not Recommended)

Manual Copy-Paste

Time Required: 10-30 minutes per document
Pros: Free, complete control
Cons: Extremely time-consuming, no formatting preservation

Adobe Acrobat Export

Cost: $15-20/month
Pros: Exports to Word, HTML
Cons: Doesn't output Markdown, expensive, messy formatting

Python Scripts (pdf2md)

Time Required: 2-4 hours setup + maintenance
Pros: Free, customizable
Cons: Requires programming knowledge, inconsistent results, no OCR

Pricing Comparison

*Manual copy-paste is perfect but takes 30x longer than BlazeDocs

Real User Workflow: PhD Student Example

"I read 50+ research papers per month for my dissertation. Before BlazeDocs, I was spending 10 hours a week manually copying key sections into Obsidian.

Now I convert entire papers in seconds and spend that time actually reading and linking ideas. Game changer."

FAQ for Obsidian Users

Can I batch convert multiple PDFs?

Not yet, but it's on the roadmap! For now, you can convert files one at a time. With 30-second processing times, it's still faster than alternatives.

Does it preserve images from PDFs?

Currently, BlazeDocs focuses on text extraction. Images are described in alt text. Image embedding is coming in a future update.

Will it work with my 500-page textbook?

Yes! The Enterprise plan supports files up to 50,000 pages. However, we recommend converting chapter by chapter for better organization in Obsidian.
