Fast, secure BMP to SVG conversion. No registration required.
BMP stores images as a dense grid of pixels, each one assigned an explicit RGB or RGBA value with no compression applied by default. A 1920x1080 BMP at 24-bit color occupies roughly 6 MB on disk regardless of what the image contains. SVG, by contrast, encodes shapes mathematically: a circle is a center point and a radius, not a cluster of colored dots. Converting BMP to SVG is therefore not a format swap in the conventional sense — it is a fundamentally different act called vectorization, where software analyzes the pixel bitmap and attempts to reconstruct the underlying geometry as paths, curves, and fills. This matters most for users working with logos, icons, line art, or simple illustrations originally scanned or exported as BMP. A vectorized SVG can be scaled to any size — printed billboard-large or shrunk to a 16x16 favicon — without the staircase aliasing that appears when you enlarge a BMP beyond its native resolution. Because SVG is an XML text format, the resulting file is also editable in any text editor or vector application such as Inkscape or Adobe Illustrator, and browsers render it natively without plugins.
BMP Image
Source formatBMP is an uncompressed raster image format native to Windows. Files are large but preserve exact pixel data with no compression artifacts. Rarely used on the web due to file size.
SVG Vector Image
Target formatSVG is an XML-based vector image format that scales to any resolution without quality loss. It is the standard for web icons, logos, and illustrations that need to look sharp on all screen sizes.
Why convert BMP to SVG
The dominant reason to move from BMP to SVG is resolution independence. BMP is a raster format tied permanently to the pixel dimensions it was saved at; enlarging it interpolates and blurs. SVG has no such ceiling. A secondary driver is file size: a simple logo or icon that occupies 200 KB as a BMP can compress to under 5 KB as SVG because the file stores equations rather than per-pixel data. Web developers also convert BMP to SVG because browsers load SVG inline via the img tag or directly in CSS, and SVGs respond to CSS styling and JavaScript manipulation in ways a BMP never can.
HOW TO CONVERT
BMP → SVG
Provide the BMP
Click or drag to upload. We accept a single BMP file per job, with an optional queue of additional images for batch mode.
Encode to SVG
The conversion decodes the BMP, resolves the colour space to sRGB and writes the SVG container around the pixel data.
Save the SVG
The download is streamed back over HTTPS. If you uploaded multiple files, a ZIP with all SVG outputs is produced instead.
Common Use Cases
Share across platforms
Send SVG files to anyone without worrying about whether they have the right software for BMP.
Embed in documents
Drop SVG output into Word, Google Docs, PowerPoint, Notion or a website without conversion warnings.
Optimize size
SVG often produces smaller files than BMP for web, email and storage.
Archive & future-proof
Store in a widely-supported format that will still open on future operating systems without legacy plugins.
BMP vs SVG — Strengths and limitations
What each format does best, and where it falls short.
BMP Strengths
- Dead-simple format — trivially easy to read and write.
- Lossless and uncompressed — perfect bit-exact pixel storage.
- Universally supported in Windows applications since 1985.
- Supports 1, 4, 8, 16, 24, and 32-bit color depths.
Limitations
- Enormous file sizes — no meaningful compression in typical use.
- Not a web format — browsers support it but nobody serves BMPs over HTTP.
- No metadata support (no EXIF, no ICC profile in practice).
SVG Strengths
- Resolution-independent — crisp at any size, from 16px icon to 4K billboard.
- Tiny file sizes for flat graphics, logos, and UI illustrations.
- Editable with any text editor; programmatically manipulable via DOM.
- Supports interactivity, CSS styling, and JavaScript inside the image.
- Accessible — text inside SVG is readable by screen readers.
Limitations
- Not suitable for photographs or complex raster imagery.
- Uploading user-provided SVG is risky — embedded scripts are an XSS vector.
- Complex SVGs with thousands of paths render more slowly than a PNG equivalent.

Quality & Compatibility
BMP carries no lossy compression — every pixel is preserved exactly — so the input data arriving at the vectorizer is clean. What happens next depends entirely on the complexity of the source image. Solid-color regions with hard edges (logos, clip art, simple diagrams) trace cleanly into closed paths. Photographs, gradients, anti-aliased text, or images with hundreds of distinct tones produce SVGs filled with thousands of tiny polygon fragments that attempt to approximate pixel clusters; the resulting file is enormous, visually approximate, and practically unmaintainable. BMP supports 1-bit (monochrome), 4-bit, 8-bit palette, 16-bit, 24-bit, and 32-bit color depths. The 32-bit variant carries an alpha channel for transparency; vectorizers that read this channel can preserve transparent regions as SVG path fills with no fill color. Color fidelity in the output paths is sampled from the source pixels, so hue and saturation are representative but not mathematically exact for edge regions where the tracer averages adjacent pixel colors. BMP contains no embedded ICC color profile, so the SVG output is implicitly sRGB. EXIF and other metadata present in some BMP variants are discarded — SVG carries only geometric and style data.
Tips for Best Results
- Keep the source BMP as high-contrast and clean as possible before converting. If the original has JPEG-style noise or a faint background gradient, flatten it to a solid color in an image editor first — even a free tool like Paint.NET can do this. Noise forces the tracer to generate thousands of micro-paths that bloat the SVG and produce muddy edges.
- For logos or icons, reduce the BMP to its essential colors before tracing. A two-color or four-color palette gives the vectorizer hard, unambiguous boundaries to follow and yields clean closed paths per color region. You can do this by converting to indexed color mode and reducing the palette count to the minimum that still looks correct.
- After downloading the SVG, open it in a browser and zoom to 400 percent to verify edge quality before using it in production. If you see jagged micro-paths or color banding along curves, the source BMP was too complex or low-contrast for clean vectorization, and you may need to manually simplify the result in Inkscape using Path > Simplify to reduce node count without visibly degrading the shape.
Frequently Asked Questions
It depends on the codecs involved. If both BMP and SVG are lossy, the pixels are re-encoded and a small amount of detail is discarded — invisible at default quality settings on photographs. If SVG is lossless (PNG, TIFF, BMP) the output keeps every pixel of the decoded BMP exactly, but cannot recover detail that BMP had already compressed away.
Often yes, especially when SVG is lossless. BMP tuned for efficient web delivery will usually produce smaller files than SVG's default settings. If file size matters, drop the quality in Advanced or pick a more compressed target format instead.
