How to convert diagram to SVG
- Drop your diagram. A PNG or screenshot of a flowchart, org chart, circuit or any line-and-box drawing on a plain background.
- Watch it trace. The background colour is found and removed, the few colours of the diagram are separated, and the boxes and lines are traced with sharp corners. The result is compared with your image and refined where it differs most.
- Download. You get an SVG with a transparent background and one path per colour. Open it in Figma, Illustrator, Inkscape or any browser.
Questions
Is it really free?
Yes. No account, no watermark, no download limit. The site is paid for by ads.
Are my images uploaded?
No. Conversion runs on your device, inside this page. Your image never leaves your browser, so it also works with confidential files.
Is the background really removed?
Yes, when the image has a plain background. The SVG then has no white rectangle and sits on any page colour.
Are thin lines kept?
Yes. Detail starts high in this mode and small shapes are not merged away, so one-pixel lines stay lines.
Is the text editable?
Here letters become shapes, which look right at any size. The chart converter turns text into editable text.
What does the match score mean?
It compares the rendered SVG with your image on colour, transparency and edges. 100% would be pixel identical. Flat artwork usually lands above 99%; photos trace into many shapes and score lower, because vectors are not made for photos.
What do the settings do?
Type picks what kind of image it is, which sets sensible defaults. Colours sets how many colours the image is split into (Auto picks them from the image and adds more where needed). Detail sets how closely curves follow the pixels: higher keeps small features, lower gives smoother shapes and smaller files.
