Why does this produce a JPEG instead of HEIC?

No browser supports native HEIC encoding due to patent and licensing restrictions on the HEVC codec used by HEIC/HEIF. JPEG is the browser-native high-quality alternative and produces visually equivalent results at 95% quality.

Is my image uploaded to a server?

No. The entire conversion runs inside your browser using the FileReader API and HTML5 Canvas. Your BMP file is never transmitted over the network.

What quality is the output JPEG?

The output uses 0.95 quality (95%), which is near-lossless for photographic content and produces files significantly smaller than BMP with no visible degradation.

Will transparency in my BMP be preserved?

BMP files do not support transparency. The conversion fills the canvas with a white background before rendering, which is the correct behavior for this format.

What is the maximum file size I can convert?

There is no hard server limit since processing is local, but very large BMP files (over 50 MB) may be slow depending on your device memory. Most BMP files convert in under a second.

Can I convert multiple BMP files at once?

This tool handles one file at a time. Simply repeat the process for each file. For bulk conversions, a desktop tool like ImageMagick is recommended.

Summary

Upload a BMP file and download it as a high-quality JPEG — the browser-safe equivalent of HEIC.

How it works

Click "Choose BMP File" and select a .bmp file from your device.
The tool reads the file using the FileReader API and draws it onto an HTML5 Canvas.
The canvas encodes the image as a high-quality JPEG (quality 0.95).
A preview of the converted image is shown alongside the original file details.
Click "Download JPEG" to save the converted file to your device.
All processing happens in your browser — no data is ever uploaded to a server.

Use cases

Reduce the file size of large BMP screenshots from Windows tools.
Prepare BMP assets for web use where JPEG or HEIC is preferred.
Convert legacy BMP graphics to a format compatible with modern devices.
