Convert BMP files to SVG online

BMP files store raw, uncompressed pixels, which makes them excellent vector source material: there are no compression artifacts to clean up. Drop a BMP below and its contents are rebuilt as layered SVG paths in your browser, ready for print, cut or further editing in any vector editor.

How to convert BMP to SVG

  1. Load your BMP file. Drag it onto the drop zone, paste it from the clipboard, or click to browse; nothing is uploaded.
  2. Tune the vector. Set the color count and simplification; adjust gamma, contrast, hue and saturation to sharpen the trace.
  3. Check with the slider. Glide between the original image and the traced vector, zooming in to inspect edges.
  4. Download. Save the layered SVG, or grab each color layer separately for cutting and printing.

BMP: uncompressed pixels mean zero surprises

BMP is one of the oldest formats still in circulation and, unlike everything else on this page, it stores pixels exactly as decoded. There is no transform to invert, no predictor to rebuild from, no quantization table: the rows are laid down directly, padded to a 4-byte boundary, with colors as plain channel values (stored in BGR order, a relic of its Windows GDI origins). Optional run-length encoding exists in a few variants, and odd color depths from 1-bit monochrome through 8-bit palettized up to 24- and 32-bit truecolor are all legitimate. Whatever variant lands in the tool, the browser flattens it to ordinary RGBA before tracing, so the pipeline treats it identically to any other decode.

Predictably, the upsides and downsides both follow from that honesty. Upside: no artifacts ever. A 1-bit BMP (the format of a thousand old clipart CDs and fax-era scans) traces as a perfect two-mask, black-and-white vector; 4-bit icons and 8-bit palettized art behave like a well-batched or dither-free GIF; 24-bit files behave like PNG. Downside: file size. Without compression a 2000×1500 BMP weighs in around 9 MB, which is exactly why the format lost the web to JPEG and PNG.

In practice, the BMP path earns its keep in two situations. Legacy archives: many old business logos, stamps, letterheads and manual scans were saved as BMP, and vectorizing them converts a dead-end file into something modern editors and cutters accept. And scanner material: BMP is still what some scanning drivers emit by default, and scanned raster is exactly where the Detail and Simplify controls earn their money. A scan is rarely perfectly square, and the straightening step in your vector editor is painless once the artwork exists as paths. If you have the same art as both BMP and PNG, they will trace identically; the tool simply does not care which uncompressed container the pixels wore.

BMP to SVG: FAQ

Are large BMP files supported?

Yes, up to the Detail limit (1536px on the long side). BMPs are uncompressed, so very large files take a moment to decode; the converter downscales automatically for tracing.

My BMP is a low-resolution scan. How do I get smooth curves?

Trace at Detail 1024 or higher and raise the Simplify slider; the curve fitter will smooth the scan noise into clean Bézier outlines.

Does BMP color depth matter?

No. 1-bit, 4-bit, 8-bit and 24-bit BMPs are all decoded by the browser first, then traced from the decoded pixels.

Why vectorize BMP files at all?

BMP is a dead-end format: huge files, poor tool support, and it blurs when scaled. The SVG output is small, editable and infinitely scalable.
