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 six 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.

The Merge PDF Files tool solves a fourth, closely related need: combining several existing PDF files, not images, into one document. Upload multiple PDFs, drag to reorder them, preview the combined result with your browser’s own PDF viewer, and download a single Konvity-branded file. Pages are copied directly from the source PDFs rather than rendered as images, so text stays selectable and searchable. If you have ever needed to merge PDF files online to combine a contract with its signature page, or to bundle several invoices into one attachment, this handles it without installing desktop software.

The Split PDF Files tool goes the other direction from Merge: dividing one PDF into several smaller files. Three ways to split are available: page ranges (automatic, one page per file, a fixed number of pages per file, or your own custom list of from-to page ranges), a page-by-page grid where you check exactly which pages to pull out into one new PDF, or a maximum file size you set, so the tool splits the document into as few files as possible while keeping each one under that size. Every page is shown as a preview thumbnail first, and unlike Merge and JPG to PDF, the output pages are exact, unmodified copies with no added logo or footer, since splitting doesn’t compose a new document the way those two tools do.

The PDF Editor covers the sixth need: actually changing what is on a page, not just converting or rearranging whole files. It adds a full editing toolbar, text boxes, freehand drawing, whiteout, highlighting, lines, arrows, shapes, and your own images, all draggable, resizable, and rotatable. Undo and redo track your entire session across every page, and a fullscreen mode gives more room to work. If you have ever needed to edit a PDF online to cover an outdated note, annotate a diagram, or sign a document by hand without installing desktop software, this is built for that.

Between the six 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, combine several receipt photos into one PDF for an expense report, merge a batch of signed contract pages into a single file before filing it away, split a large scanned report down to just the one page a client actually needs, or open that page in the PDF Editor to correct a figure before sending it back. 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, combining images into a single PDF, merging several PDF files into one, splitting one PDF into several, or editing a PDF directly, all six tools are free, require no sign-up, and are built to run entirely on your own device.
