--- title: "Supported file types" description: "Every file type Markdrop renders, from HTML pages and PDFs to spreadsheets, Word documents, images, video, audio and zipped sites." canonical_url: https://docs.markdrop.in/files/supported-types last_updated: 2026-10-30 prerequisites: [/get-started/first-file] site: "Markdrop Docs" index: https://docs.markdrop.in/llms.txt --- # Supported file types Each file you upload opens in a viewer made for its type, so readers see the content rather than a download prompt. This page lists what Markdrop accepts and what readers get for each. ## The full list | File | Extensions | Readers see | Size limit | | --- | --- | --- | --- | | HTML page | `.html`, `.htm` | The page itself, running live | 25 MB | | PDF | `.pdf` | Pages with zoom and page count | 25 MB | | Spreadsheet | `.xlsx`, `.xls`, `.csv` | A grid with row numbers, column letters and a tab per sheet | 25 MB | | Word document | `.docx` | The document's text, headings, lists and tables | 25 MB | | Image | `.png`, `.jpg`, `.jpeg`, `.gif`, `.webp`, `.svg` | The full-size image | 25 MB | | Text | `.txt`, `.json` | Text with line numbers and a **Wrap lines** toggle | 25 MB | | Website | `.zip` | A multi-page site, opening at its `index.html` | 25 MB zipped | | Video | `.mp4`, `.mov`, `.webm`, `.ogv` | A player with speed control and keyboard shortcuts | 2 GB | | Audio | `.mp3`, `.m4a`, `.wav`, `.ogg` | The browser's audio player | 2 GB | Markdrop checks the type when you upload. A file that isn't on this list is refused, with the list of accepted extensions. Readers can always choose **Download** to get the original file, byte for byte. ## How each type renders ### HTML pages An HTML file is served as the page, so its scripts, styles and fonts work. It runs inside a sandboxed frame on a separate domain, so it can't read anything from Markdrop or the reader's account. To publish HTML you have as text rather than a file, see [Publish an HTML page](https://docs.markdrop.in/files/html-pages). ### PDFs PDFs open in a built-in reader with page-by-page scrolling and zoom. It shows the first 50 pages; for a longer PDF it says "Showing the first 50 of N pages. Download to see the rest." ### Spreadsheets Excel workbooks open with a tab for each sheet; use the arrow keys to move between tabs. CSV files open as a single sheet. Markdrop shows the values in each cell; charts and pictures in a workbook aren't drawn. ### Word documents A `.docx` is converted to clean web text: headings, paragraphs, lists, tables, links and images. The structure comes through; exact page layout, fonts and spacing don't. If the layout matters, export a PDF and upload that instead. ### Images Images open at full size. An SVG can contain scripts, so it gets the same sandbox on a separate domain as an HTML page. ### Text and JSON Text opens with line numbers. Very large files are cut at 2,000,000 characters or 100,000 lines, and the viewer says so; **Download** still gives the whole file. ### Video and audio Video plays in Markdrop's player, which streams and seeks without downloading the whole file first. Audio uses the browser's own player. See [Video and audio](https://docs.markdrop.in/files/video-and-audio). ### Zipped websites A `.zip` of a built site is unpacked and served as a site, so links between its pages work. See [Publish a zipped website](https://docs.markdrop.in/files/websites). ## Not supported PowerPoint (`.pptx`) and other formats not in the table aren't accepted. Files can't be end-to-end encrypted; only documents can. Markdown isn't uploaded as a file. Paste it into [a document](https://docs.markdrop.in/get-started/first-document) instead, where it renders with headings, diagrams and math. In a workspace, a `.md` file you drop onto a folder becomes a document there. ## More about files **[Size and storage limits](https://docs.markdrop.in/files/limits)** 25 MB per file, 2 GB for video and audio, 20 GB per account. **[Upload large files](https://docs.markdrop.in/files/large-uploads)** Resumable, verified uploads from the terminal. **[Publish an HTML page](https://docs.markdrop.in/files/html-pages)** Turn HTML from an AI assistant into a live link. **[Publish a zipped website](https://docs.markdrop.in/files/websites)** Serve a whole static site at one link. **[Replace a file](https://docs.markdrop.in/files/replace-and-versions)** Swap the file behind a link and restore earlier versions. **[Video and audio](https://docs.markdrop.in/files/video-and-audio)** The player, shortcuts, and what to do when a video won't play.
