Why BMP Format?

BMP (Bitmap) is an uncompressed format with specific use cases:

•
Uncompressed: No compression artifacts for editing
•
Legacy software: Required by some older Windows programs
•
Editing workflows: Useful for lossless image editing
•
Large files: BMP files will be 10-20x larger than JPG
Step 2

Once uploaded, you'll see a preview of your image file. The converter will display:

•
Image preview: Visual preview of your uploaded JPG image
•
File information: File name and size details
•
Image dimensions: Width and height of your image
Step 3

The conversion happens automatically and instantly after upload using the HTML5 Canvas API! The process is:

•
Instant: Conversion starts automatically 300ms after upload
•
Uncompressed output: Creates true BMP with no compression
•
File size increase: BMP will be 10-20x larger than JPG (this is expected)
•
Quality: No additional compression artifacts added
Step 4

Frequently Asked Questions

Why would I want to convert JPG to BMP?

Convert to BMP format when you need compatibility with legacy Windows software, require an uncompressed format for editing, or work with systems that specifically require BMP files. BMP is also useful for certain printing workflows.

Will the BMP file be much larger?

Yes! BMP files are uncompressed, so they will be 10-20x larger than the original JPG. For example, a 500KB JPG might become a 5-10MB BMP. This is normal and expected for uncompressed formats.

Are my images uploaded to a server?

No! All image conversions happen locally in your browser using HTML5 Canvas technology. Your images never leave your device, ensuring complete privacy and security. This also makes the conversion instant.

Will converting to BMP improve quality?

No, converting from JPG to BMP won't restore quality lost during JPG compression. However, it prevents further quality loss and provides an uncompressed format for additional editing without introducing new compression artifacts.

Is BMP still used today?

BMP is mostly legacy format but still used by some Windows software, screen capture tools, and specific professional workflows. For most modern uses, formats like PNG or WebP are better alternatives.

What file size limits are there?

The converter handles images up to 50MB and dimensions up to 16,384 pixels. Note that the resulting BMP will be much larger. You might also check our BMP to JPG converter for the reverse conversion.
