Step-by-step tutorials and practical tips for PDF conversion, extraction, and common workflows.
How to Convert PDF to Text
Plain text is the most portable thing you can pull out of a PDF. This guide shows you how to do it in a couple of clicks, and — more usefully — explains what to do when the output is not what you expected.
How to Convert PDF to CSV
Getting a table out of a PDF and into a spreadsheet is one of the most common — and most fiddly — PDF jobs there is. Here is how to do it, and how to tell whether the result can be trusted.
How to Convert PDF to Markdown
Markdown is the sweet spot between plain text and full HTML: you keep the document structure, but the result is still readable as-is. That makes it the best format for docs, notes and anything headed for an LLM.
How to Convert PDF to HTML
Converting a PDF to HTML makes its content work on the web: searchable, responsive, selectable and accessible to screen readers. This guide explains what you get and where the limits are.
How to Convert PDF to SVG
SVG is the right target when you care about how the page looks: it scales to any size without going blurry, and it drops straight into web pages, Figma or Illustrator.
How to Convert a Jupyter Notebook to PDF
Exporting a notebook to PDF is famously annoying: the standard route wants a full LaTeX distribution just to produce one file. This does it in your browser instead.
How to Convert HEIC to PDF
HEIC is what your iPhone saves photos as by default. It is an excellent format that almost nothing outside the Apple ecosystem will open — which is exactly why people need to convert it.

A .txt file has no pages, no margins and no fixed appearance. Turning it into a PDF is how you make it printable, attachable and stable — everyone sees exactly the same thing.
How to extract text from a scanned PDF
Read this first if a converter gave you an empty file. Scanned PDFs need OCR, and our tool deliberately does not pretend otherwise.
How to get a PDF table into Excel
The route that keeps your columns: PDF to CSV, then CSV into Excel. No retyping, no upload.
Converting PDF to Markdown for LLMs and RAG
Structure survives the conversion, so your chunker knows where sections begin and end.

Your iPhone photos are fine. Windows just does not ship the decoder for free any more.
Jupyter notebook to PDF without LaTeX
Skip the multi-gigabyte TeX install. Drop the .ipynb file in and get a PDF.
How to convert a PDF without uploading it
Modern browsers can parse and generate PDFs on their own. No server needs to see your file.
Why copying from a PDF breaks the formatting
A PDF stores where each piece of text sits on the page, not what it means. Copy-paste loses the layout.
Converting PDF to SVG for design work
Vector in, vector out. Useful when a client sends a logo as a PDF and you need it on the web.
