free · in-browser · no upload
Drop your DOT file. We'll convert it to SVG right here in your browser, your file never leaves your device.
Select your file here to get started
or drop your file here.
Accepts .dot, .gv, .graphviz, .txt
How it works
Click the dropzone above or drag a DOT from your desktop. Files of any size, there's no upload, so there's no upload limit.
The conversion runs entirely in this tab using JavaScript and WebAssembly. Your file never touches our servers, we don't have any.
Get your SVG the moment the conversion finishes. Convert another, or close the tab.
Your file is never uploaded. The entire conversion runs in your browser using WebAssembly. We can't see what you convert because we have no server to see it.
Server converters cap free users at 1-2 GB and gate larger files behind a paid plan. Since nothing uploads, our limit is whatever your browser can handle.
No account required. No watermark on the output. No queue. Drop a file, get a converted file.
Why convert DOT → SVG
DOT is the Graphviz source language for directed and undirected graphs (CS textbooks, RFC diagrams, dependency graphs, state machines). To publish or embed the result you need SVG, the vector format that scales cleanly. Runs the upstream Graphviz dot engine compiled to WebAssembly, so the layout exactly matches what dot -Tsvg produces on the command line.
You drafted a microservice dependency graph in DOT and want to drop it into a Notion doc as a scalable image. Convert here, the SVG is self-contained.
"Graphviz failed to render the DOT source" error.
DOT is strict about syntax. Common gotchas: a missing closing brace, a node label that contains a hyphen without quotes, or a typo on the graph keyword (digraph vs graph). Validate locally with dot -Tsvg input.dot first if you have it installed.
Formats involved
DOT is a file format we support converting. Detailed format information is being added, for now, drop your file in the converter above and you'll get the conversion you came for.
How to open
Most operating systems open this format with a default application; if not, search for a free reader/viewer for the format.
SVG describes images as math (paths, shapes, fills) instead of pixels. The result scales to any size without losing sharpness, perfect for logos, icons, and UI graphics. SVG files are XML text, which means they can be edited in any text editor and styled with CSS. Browsers render SVG natively; for rasterized output (PNG/JPG) you can convert.
How to open
Every browser displays SVG inline. Vector editors (Illustrator, Affinity Designer, Inkscape, Figma) edit them. Any text editor can open the underlying XML.

FAQ
Yes. No signup, no watermark, no daily file count limit. Every conversion runs in your browser, your file never touches our servers because there are no servers.
Nowhere. The conversion runs entirely in your browser using JavaScript and WebAssembly. Your file is never uploaded to our servers. We don't have any servers handling files, there's nothing for us to log, store, or accidentally leak.
Whatever your browser can hold in memory. Practically, this means a few hundred MB on most computers, significantly larger than the 1-2 GB caps that server-upload converters charge for. Very large files (multi-GB) may require closing other browser tabs first.
File interchange. Logos, icons, illustrations, and any graphic that needs to scale crisply. The most common reason to convert is compatibility, SVG works in places where DOT doesn't, or vice versa.
Most operating systems open this format with a default application; if not, search for a free reader/viewer for the format.
Once the page is loaded, the conversion itself runs entirely offline. The first time you use a tool, your browser downloads the conversion library (a one-time cache). If you reload while offline, the page won't load, but you can install the site as a Progressive Web App for full offline use.
Single file at a time for now. Batch conversion is on the roadmap, for now, drop one file, download the result, then convert the next.
