Fast, secure RTF to BMP conversion. No registration required.
Here is the short version — RTF is the 1987-era Rich Text Format, Microsoft's plain-ASCII document interchange format. Hence the need for BMP. Converting RTF to BMP fixes the mismatch between a file you have and the tool that needs to open it. KaijuConverter runs the conversion with the right backend for the job (libreoffice), keeps the source file untouched and deletes both RTF and BMP copies within two hours. No account required, nothing installed locally. Context: RTF is the 1987-era Rich Text Format, Microsoft's plain-ASCII document interchange format. BMP is the uncompressed Windows bitmap format — bulky but pixel-perfect.
Rich Text Format
Source formatRTF is a cross-platform document format that supports basic text formatting like bold, italic, fonts, and colors. It is readable by virtually all word processors, making it useful for maximum compatibility.
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 RTF to BMP
BMP is better supported than RTF in the workflow you are targeting. Converting trades any niche advantages of RTF for broad compatibility, and the conversion itself is fast because the two formats share the same conceptual content.
HOW TO CONVERT
RTF → BMP
Upload the RTF
Drop your file into the browser uploader. We transfer over HTTPS and queue the conversion.
Convert through libreoffice
Our libreoffice-based pipeline reads the RTF, applies the right decoder and emits a faithful BMP.
Download the BMP
Grab the result when it lands. Both files delete automatically within two hours — nothing lingers on our servers.
Common Use Cases
Share across platforms
Send BMP files to anyone without worrying about whether they have the right software for RTF.
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 RTF 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.
RTF vs BMP — Strengths and limitations
What each format does best, and where it falls short.
RTF Strengths
- Plain ASCII — portable, grep-able, and diff-friendly.
- Supported by every word processor on every OS since 1990.
- Cannot carry macros or embedded code — relatively safe to open.
- Simple enough to parse by hand or generate with a small script.
- Good interchange format when DOCX compatibility is shaky.
Limitations
- Frozen in 2008 — no modern features (no comments, poor styles, no track changes).
- File sizes are bigger than DOCX for the same content (no compression).
- Images are base64-encoded inline, inflating files further.
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).

- Document with embedded images 2-20 MB
BMP

- 4K image (3840×2160) ~25 MB
- Scanned A4 at 300 dpi ~25 MB
Quality & Compatibility
The conversion preserves the important content and lets you control quality trade-offs through Advanced options. Lossless paths produce BMP output that matches the RTF content exactly; lossy paths re-encode at transparent defaults unless you request otherwise. Metadata transfers where both formats support it.
Tips for Best Results
- Always keep the original RTF file alongside the BMP — you may need it later if requirements change.
- Check a small sample of the BMP in its destination application before batch-converting a large archive.
- For recurring conversions, the REST API on paid plans automates the whole pipeline programmatically.
Frequently Asked Questions
Yes. The free tier accepts files up to 25 MB without registration, email capture or watermarks; paid plans go up to 2 GB. Paid plans raise the size cap, enable batch conversions and provide a REST API for automation, but nothing on the free tier is quality-limited — the output is exactly the same as on any paid plan.
Uploads run over HTTPS, files are processed in isolated containers, and both the source RTF and the BMP output are auto-deleted within two hours. No account is required, file contents are never logged, and KaijuConverter does not use uploads for AI training. The paid plan adds a signable data-processing agreement for regulated workflows.
Most files finish in well under a minute. Small images and documents are typically ready in a few seconds; large video or audio files scale roughly with duration. Upload speed from your network is usually the dominant factor, not server time.
