SVG is an XML-based vector format that stays sharp at any size. Current browsers open SVG, but support in programs and services is uneven.
BMP is Windows' basic bitmap that stores pixels as they are, without compression. When you convert SVG to BMP, you can open it in more places and a solid background replaces transparency. See the comparison below for what changes.
This converter reads the file itself to confirm it is SVG, then converts it to BMP right in your browser. Your image is never uploaded.
SVG vs BMP: what's the difference?
| Item | SVG | BMP |
|---|---|---|
| Compression | Vector (stored as math) | None (uncompressed) |
| Transparent background | Yes | No |
| Animation | Yes | No |
| Introduced | 2001 | 1990 |
| Support in programs and upload forms | moderate | broad |
| Shown directly in browsers | Yes | Yes |
| Photo file size (JPG = 1) | n/a | about 12× |
What is SVG?
SVG stores lines, shapes and curves as math in text (XML) instead of pixels. It stays sharp however far you zoom, and a simple logo can be just a few KB.
What is BMP?
BMP is a bitmap format from Windows that mostly stores pixel values as they are, without compression. Its simple structure makes it easy for programs to read, but the files are so large that it is rarely used on the web.
What changes when you convert SVG to BMP
Transparent areas are filled with the background color you choose
BMP can't represent transparency. Transparent and semi-transparent areas are composited onto the background color in the options (white by default), so pick a matching color first if the image will be used on a dark screen.
The vector becomes a fixed-size pixel image
The moment you convert SVG to BMP, the resolution is fixed. Set the width in px in the options first so it is drawn sharply at the size you need; enlarging it later makes it blurry.
Moving images keep only their first frame
BMP can't hold animation. If your SVG file is animated, only the first frame is converted.
With no compression, the file size grows a lot
BMP stores pixels as they are. A 1920×1080 image becomes about 6MB, so unless equipment or software requires BMP, another format is recommended.
BMP has no quality setting
BMP is none (uncompressed), so the quality slider doesn't apply. Instead, when converting from SVG you can manage file size by resizing (exact width and height, or a percentage).
How the file size changes
SVG is a resolution-independent vector, so its size depends on how complex the shapes are. A simple logo is far smaller as SVG than as BMP, but once rasterized it needs pixel data for the exact width and height you choose.
BMP opens in more places
Support for SVG in programs, document tools and upload forms is moderate, while BMP is broad. If you need to upload somewhere SVG wouldn't open, try again after converting.
When to convert
- You need to upload to a program, messenger or upload form that can't open SVG
- You need to feed legacy equipment or embedded software that only reads BMP
- You're preparing an image for typical BMP uses (input for legacy equipment and software, simple image-processing exercises)
