Are my images uploaded to a server?

No. The entire conversion runs inside your browser using the HTML5 Canvas API. Your BMP file never leaves your device.

Why is the JPG file so much smaller than the BMP?

BMP files store every pixel without compression, making them very large. JPEG uses lossy compression optimized for photographic content, which can reduce file size by 90% or more while keeping the image visually sharp.

Does BMP support transparency?

Some BMP variants (32-bit with alpha) support transparency, but JPEG does not. Any transparent pixels in the original BMP are composited onto a white background before export.

What quality setting should I use?

For photos and complex images, 80–90% gives excellent visual quality with significant size savings. For simple graphics or icons, 60–75% is usually sufficient. Use 100% only when maximum fidelity is required.

Is there a file size limit?

The practical limit is your browser's available memory — typically several hundred megabytes. Very large BMP files (e.g., high-resolution scans) may be slow to process on low-end devices.

What browsers are supported?

All modern browsers — Chrome, Firefox, Safari, and Edge — support the Canvas API used for conversion. Internet Explorer is not supported.

Summary

Upload a BMP file and download a JPG — adjust JPEG quality, convert instantly, entirely in your browser with no file upload.

How it works

Select or drag a BMP image onto the upload area.
The browser decodes the BMP file using its built-in image decoder.
The Canvas API draws the decoded pixels onto a white background (replacing any BMP transparency).
Use the quality slider to choose a JPEG quality from 1% to 100%.
A live preview and file size comparison update instantly as you adjust quality.
Click "Download JPG" to save the converted JPEG to your device.

Use cases

Reduce the file size of large BMP screenshots or scanned documents for web sharing.
Convert BMP images from legacy software to JPEG for broad compatibility.
Prepare bitmap artwork for email attachments by shrinking file size.
Convert BMP exports from paint or design tools into JPEG for photo workflows.
Process images privately without uploading to any third-party service.
Compress raw bitmap captures for use in presentations or reports.
Convert BMP wallpapers or textures to JPEG for games or apps.
Archive BMP graphics in JPEG format for compatibility with modern photo viewers.
