Fast, secure SVGZ to BMP conversion. No registration required.
SVGZ is a gzip-compressed SVG — same vector content, smaller download size. Reaching a BMP from there is one hop. A SVGZ to BMP conversion is almost always about making an image land cleanly in another piece of software. Compressed SVG is well-suited to its original niche, but BMP Image opens on more platforms or fits better into a publishing pipeline. Upload a SVGZ file above, pick any quality knobs, and download a ready-to-use BMP. In practice SVGZ is a gzip-compressed SVG — same vector content, smaller download size. On the other end, BMP is the uncompressed Windows bitmap format — bulky but pixel-perfect.
Compressed SVG
Source formatSVGZ is a gzip-compressed version of SVG vector graphics, offering the same quality in a smaller file.
BMP Image
Target 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.
Why convert SVGZ to BMP
Converting keeps the picture recognisable end-to-end while changing the container that ships it. BMP typically wins on one of three fronts: broader software support, smaller files for the same visual quality, or features like transparency that SVGZ cannot express. The conversion itself is fast because both sides are raster formats.
HOW TO CONVERT
SVGZ → BMP
Upload your SVGZ
Start by dropping the SVGZ onto the uploader. Files up to 25 MB go through on the free tier without registration; paid plans go up to 2 GB.
Conversion happens server-side
Our imagemagick-based pipeline reads the SVGZ pixel grid, preserves resolution and colour profile, and encodes a clean BMP.

A download button appears as soon as the BMP is ready. Save locally or share the short-lived URL.
Common Use Cases
Share across platforms
Send BMP files to anyone without worrying about whether they have the right software for SVGZ.
Embed in documents
Drop BMP output into Word, Google Docs, PowerPoint, Notion or a website without conversion warnings.
Optimize size
BMP often produces smaller files than SVGZ 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.
SVGZ vs BMP — Strengths and limitations
What each format does best, and where it falls short.
SVGZ Strengths
- Tiny file sizes — huge ratio on XML-heavy SVGs.
- Drop-in replacement for .svg in every major browser.
- No client-side decompression cost — browsers handle it transparently.
- Useful for offline/embedded distribution.
Limitations
- Not human-readable directly — requires decompression to edit.
- Some older software (especially Windows Explorer previews) may not recognize the extension.
- Redundant on servers that already gzip/brotli SVG in transit.
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).

SVGZ vs BMP — Typical file sizes
Approximate file sizes for common scenarios.
SVGZ
- Icon SVG (gzipped) 1-3 KB
- Complex diagram (gzipped) 10-50 KB
- Map SVG (gzipped) 50 KB - 2 MB
BMP
- Small icon (32×32) 4 KB
- Screenshot (1920×1080) ~6 MB
- 4K image (3840×2160) ~25 MB
- Scanned A4 at 300 dpi ~25 MB
Quality & Compatibility
Converting keeps resolution, aspect ratio and colour profile identical to the source. Metadata (EXIF, XMP) transfers where BMP supports it; otherwise it is dropped. If the SVGZ contained an alpha channel and BMP does not support transparency, the background is flattened to white by default.
Tips for Best Results
- When uploading to Retina / high-DPI contexts, render the BMP at 2× the CSS pixel size; the crispness gap over 1× is noticeable on modern screens.
- Strip EXIF metadata from the BMP before publishing if the SVGZ came from a phone camera — it often contains GPS coordinates and device IDs.
- If the SVGZ is a screenshot of text or UI, prefer a lossless BMP target to avoid the JPEG-style ringing around glyph edges.
Frequently Asked Questions
It depends on the codecs involved. If both SVGZ and BMP are lossy, the pixels are re-encoded and a small amount of detail is discarded — invisible at default quality settings on photographs. If BMP is lossless (PNG, TIFF, BMP) the output keeps every pixel of the decoded SVGZ exactly, but cannot recover detail that SVGZ had already compressed away.
Often yes, especially when BMP is lossless. SVGZ tuned for efficient web delivery will usually produce smaller files than BMP's default settings. If file size matters, drop the quality in Advanced or pick a more compressed target format instead.
KaijuConverter uploads over HTTPS, processes the image in an isolated container and deletes both the source and the output within two hours. No account is required, file contents are never logged, and we do not use uploads to train any model. For confidential material, the paid plan includes a data-processing agreement.
