What does converting JPEG to BMP mean?
JPEG is a lossy format optimized for photographs (identical to JPG), while BMP is an uncompressed raster format that stores every pixel with no compression at all. Convert JPEG to BMP for uncompressed output compatible with all Windows apps and legacy software.
JPEG — the same format as JPG under a different file extension — uses lossy compression tuned to human perception, producing small files ideal for photographs at the cost of some fine detail and no transparency support.
BMP files are typically 10-20 times larger than an equivalent JPG or PNG because no compression algorithm is applied. It remains common in Windows-native applications and legacy software.

When to convert JPEG to BMP
Preparing JPEG files for legacy Windows applications that require raw, uncompressed pixel data
Convert JPEG images to BMP when your project specifically calls for legacy Windows applications that require raw, uncompressed pixel data.
Reducing file size
If BMP compresses better than JPEG for your content, converting can significantly cut storage and bandwidth needs.
Improving compatibility
Some platforms and software only accept certain formats — converting to BMP ensures your JPEG files open everywhere they need to.
Batch migrating a library
Convert a whole folder of JPEG images to BMP at once instead of opening each file individually in an editor.

Frequently Asked Questions
Will converting JPEG to BMP reduce image quality?
Since BMP is a lossless format, no additional quality is lost when converting your JPEG file. If the original JPEG was already compressed with quality loss, that loss can't be recovered, but nothing further is discarded.
Does BMP support transparency?
No, BMP does not support transparency. Any transparent areas in your JPEG file will be filled with a solid background (typically white) when converted to BMP.
Is it safe to convert JPEG files to BMP here?
Yes. The whole JPEG to BMP conversion runs locally in your browser using the Canvas API — your JPEG files are never uploaded to a server.
Can I convert several JPEG files to BMP at once?
Yes, drop multiple JPEG files at once and click Convert All — each one is converted to BMP and can be downloaded individually or as a ZIP.
Is there a size limit for JPEG uploads?
There's no hard limit set by Pixvert for JPEG files, but very large files depend on your device's available memory to convert smoothly.
Can I use the BMP output commercially after converting?
Yes, converting JPEG to BMP only changes the file format — it doesn't alter your rights over the image or add a watermark.
