SVG to BMP Converter

What this tool does

This SVG to BMP converter rasterizes scalable vector graphics into uncompressed BMP bitmap images entirely within your browser. It takes your SVG file – a collection of mathematical paths, shapes, and styles – and renders it onto a pixel grid at any resolution you choose. The result is a 32‑bit BMP file that preserves the full color depth (with alpha channel) and can be opened by virtually any image viewer, editor, or legacy software.

Because BMP is uncompressed, every pixel is stored exactly as rendered, making the format ideal for archival, printing, or further processing where lossless quality is essential. The entire conversion pipeline – from SVG parsing to BMP encoding – runs locally via JavaScript and the Canvas API. No data is ever sent to a server.

Key features

Supported files & limits

Input: SVG files (.svg) conforming to SVG 1.1 / 2.0. The SVG must be valid XML. Embedded raster images (base64) are supported, but externally linked images may not load due to browser security restrictions.

Output: Windows BMP (.bmp) – 32‑bit with alpha channel. No compression, no quality loss.

Practical limits: There are no hard server limits. Performance depends on your device. We recommend keeping SVG files under 10 MB and output dimensions below 5000×5000 pixels to avoid excessive memory usage.

Practical use cases

Frequently asked questions

BMP (Bitmap) is a raster graphics format that stores pixel data without compression, resulting in high-quality, lossless images. Converting SVG to BMP is useful for legacy software, embedded systems, printer workflows, and scenarios where uncompressed image data is required. Unlike SVG’s vector paths, BMP represents a fixed grid of pixels, making it compatible with virtually all image viewers and editors.

Yes, this tool outputs 32-bit BMP files that include an alpha channel. Transparent areas of your SVG (fully transparent pixels) will be preserved as alpha values in the BMP. However, semi-transparent regions (partial opacity) are flattened against a white background during rasterization, because the browser’s SVG rendering engine composites the image before we encode it. For best results, use hard-edged transparency (opacity 0 or 1) if exact alpha is critical.

Your SVG file is loaded into an HTML Image element, which uses the browser’s native SVG rendering engine to interpret all paths, shapes, gradients, and text. The rendered result is drawn onto a Canvas at your chosen resolution. The pixel data is then read from the Canvas and encoded into a complete BMP file (with BITMAPFILEHEADER and BITMAPINFOHEADER) directly in JavaScript. No server is involved – the entire process happens locally.

Because SVG is resolution-independent, you can pick any output size without losing quality. For general use, 1024×768 or 1280×720 works well. For print or archival purposes, higher resolutions like 1920×1080 or custom dimensions are recommended. If you plan to edit the BMP further, choose a resolution that matches your target canvas. The original size (based on the SVG’s width/height attributes or viewBox) is a safe default.

Yes, you can select or drag multiple SVG files at the same time. Each file will be converted individually to a separate BMP. The selected output resolution applies to all files in the batch. After conversion, you can download the BMPs one by one or save them all as a ZIP archive for convenience.

Since BMP is uncompressed, there is no quality loss from compression. The rasterization process maps the smooth vector shapes onto a pixel grid, so the sharpness depends on the output resolution you select. At high resolutions, curves and text will appear crisp. At very low resolutions, some detail may be lost, but that is a limitation of the pixel grid, not the conversion itself.

Gradients and patterns are rendered faithfully by the browser’s SVG engine. Text using system fonts will appear correctly; however, custom fonts referenced via external URLs may fall back to default fonts for security reasons. To ensure exact text rendering, convert text to paths in your vector editor before uploading. Embedded raster images (using base64 data URIs) are supported, but images linked via external URLs may not load.

There are no artificial limits. The tool will process SVGs as long as your browser has enough memory. However, BMP files are uncompressed, so large dimensions (e.g., 4000×3000) produce very large files (40+ MB). Keep an eye on memory usage if converting many high-resolution SVGs. A practical recommendation is to stay within 5000×5000 pixels per image.

When you select 'Original' size, the converter uses the SVG’s native width/height attributes (or viewBox if dimensions are missing). The preserveAspectRatio attribute is respected during rasterization. If you choose a specific output size with the 'Fit' resize mode, the image is scaled proportionally to fit within those dimensions, centered on a white background. 'Stretch' mode forces the image to fill the exact dimensions, ignoring the original aspect ratio.

Absolutely. Click the 'Custom' button in the output size settings and enter any width and height (up to 5000 pixels). Together with the 'Fit' or 'Stretch' resize mode, you have full control over the final pixel dimensions of your BMP files.

Yes, your data is completely safe. The conversion process runs entirely inside your browser using JavaScript and the Canvas API. No files are uploaded to any server. Your SVGs remain in local memory and are cleared as soon as you close the page or clear your selections. The only external resources are the JSZip library (loaded from a CDN) for creating ZIP archives.

BMP is an uncompressed format. Each pixel is stored individually (usually 4 bytes per pixel for 32-bit), so the file size grows rapidly with dimensions. For example, a 1000×1000 BMP is about 4 MB. In contrast, SVG describes shapes mathematically and is often tiny. This tool gives you the raw pixel data, which is ideal when lossless, uncompressed images are required.
