What does converting JPG to BMP mean?
JPG is a lossy format optimized for photographs, while BMP is an uncompressed raster format that stores every pixel with no compression at all. Convert JPG to BMP for use in applications that require raw, uncompressed image data.
JPG uses lossy compression tuned to how the human eye perceives detail, producing much smaller files than PNG for photographic content. It doesn't support transparency, and repeated re-saving can introduce visible compression artifacts over time.
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 JPG to BMP
Preparing JPG files for legacy Windows applications that require raw, uncompressed pixel data
Convert JPG 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 JPG 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 JPG files open everywhere they need to.
Batch migrating a library
Convert a whole folder of JPG images to BMP at once instead of opening each file individually in an editor.

Frequently Asked Questions
Will converting JPG to BMP reduce image quality?
Since BMP is a lossless format, no additional quality is lost during this conversion. If your original JPG file was already compressed with quality loss, that original 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 JPG file will be filled with a solid background (typically white) during conversion.
Is it safe to convert my images here?
Yes. All conversion happens locally in your browser using the Canvas API — your files are never uploaded to a server.
Can I convert multiple files at once?
Yes, drop several files at once and click Convert All — every file is processed and can be downloaded individually or as a ZIP.
Is there a file size limit?
There is no hard limit set by Pixvert, but very large files depend on your device's available memory to process smoothly.
Can I use the converted images commercially?
Yes, Pixvert only changes the file format — it does not alter your rights over the image or add any watermark.
