Document Tools

Document files are everywhere: PDFs from banks and government offices, Markdown notes from developers and writers, scanned contracts sitting in a folder somewhere on your computer. Most of the time, the format you have is not the format you actually need. A PDF might need to become searchable, editable text. A Markdown file might need to become something you can print, email, or submit for review. Konvity’s document conversion tools handle both of those jobs, and they do it entirely inside your browser, so nothing about your document ever has to leave your device.

This category has three focused tools rather than one do-everything converter that does nothing particularly well. The PDF to Text Converter pulls text out of any PDF, and if the PDF turns out to be a scanned image with no real text layer, it can run on-device OCR to recognize the text anyway, then let you download the result as plain text or as a real, editable Word (.docx) file. This makes it one of the more complete free tools to convert PDF online, since it handles both normal and scanned documents without switching to a different site for OCR.

The Markdown to PDF Converter goes the other direction: it takes plain Markdown, whether pasted in directly or uploaded as a .md file, and turns it into a properly paginated, professionally formatted PDF with real, selectable text, not a screenshot or flattened image. If you have ever searched for a way to convert Markdown to PDF online without installing a static site generator or a command-line tool, this is built for exactly that.

The JPG to PDF Converter handles a different, equally common need: combining several image files into one PDF. Upload multiple JPG, PNG, or other images, reorder or rotate them as needed, and download a single Konvity-branded PDF with one image per page. If you have ever needed to convert JPG to PDF online for scanned pages, receipts, or ID photos, without installing a scanner app or a desktop PDF tool, this covers that job.

Between the three tools, most everyday document conversion needs are covered. Someone digitizing an old paper contract can scan it with a phone, run OCR, and get an editable Word file out the other end. A developer with a README.md file can turn it into a PDF to send to a non-technical stakeholder. A student can convert lecture notes written in Markdown into a printable study guide. A freelancer can pull the text out of a client’s scanned invoice to copy the numbers into a spreadsheet, or combine several receipt photos into one PDF for an expense report. None of these are exotic use cases. They are the kind of small, recurring task that used to mean opening a separate desktop program, or worse, retyping a whole document by hand.

Every document you upload here is processed locally, using your browser’s own JavaScript engine and, for OCR, a WebAssembly build of the Tesseract OCR engine running entirely on your device. Nothing is sent to a server, nothing is stored, and no account is required to use any of the tools. This matters more for documents than almost any other file type, since PDFs, Markdown files, and scanned images often contain exactly the kind of sensitive information (contracts, personal letters, financial statements) that you would not want passed through a third-party server you cannot see into.

A quick note on how PDF text extraction actually works: a PDF can either have a real text layer (the kind you can already select and copy in a normal PDF viewer) or it can be a scanned image with no text behind it at all. The PDF to Text Converter checks each page and only falls back to OCR on pages that actually need it, which keeps the fast path fast for ordinary text-based PDFs while still handling scanned pages when it has to. For Markdown, the converter supports GitHub-Flavored Markdown, so headings, tables, code blocks, blockquotes, and links all come through correctly instead of being flattened into plain, unstyled text.

More online document tools, including additional format conversions, are planned for this category over time. For now, if your task involves getting text out of a PDF, turning Markdown into something presentable, or combining images into a single PDF, all three tools are free, require no sign-up, and are built to run entirely on your own device.
