Converting to BMP won't restore lost quality
Your JPG file has already undergone lossy compression. Converting to BMP preserves what's left — it prevents further degradation from re-saving — but it will not magically sharpen a blurry image or recover discarded audio frequencies.
Some metadata may not survive
Your JPG file may contain EXIF, IPTC, XMP, ICC metadata. BMP has limited or no support for these metadata types. Location data (GPS), camera settings, and color profiles may be stripped during conversion.
About JPG to BMP Conversion
Dealing with a JPG file that won't open on your device? You're not alone — JPG compatibility issues are one of the most common reasons people search for a file converter. JPG (JPEG) uses lossy compression, making it ideal for photographs and complex images where small file size matters more than pixel-perfect quality.
The fix is simple: convert your JPG to BMP. BMP is an uncompressed raster format that preserves every pixel but produces very large files. This conversion lets you preserve files for long-term archival, solving the problem in seconds rather than hours of troubleshooting.
Full Name: JPG uses JPEG Image, while BMP uses Bitmap Image. Compression: JPG uses Lossy, while BMP uses None (uncompressed). Transparency: JPG uses No, while BMP uses No. Converting JPG to BMP maintains high quality with CocoConvert's optimised encoder settings.

What Happens When You Convert JPG to BMP
Your JPG image is decoded into raw pixel data, then re-encoded as BMP. Current quality is preserved as-is — no further degradation.
Your JPG file is decoded — the compressed/stored pixel data is expanded into raw RGB pixels
Pixels are re-encoded using no compression (raw pixel storage)
Metadata (EXIF, ICC profiles) is transferred where BMP supports it
The BMP file is saved and ready for download

Should You Convert JPG to BMP?
When to Convert
- ✓You need maximum device and software compatibility
When NOT to Convert
- ✗You're hoping to improve image/audio quality — converting lossy to lossless cannot recover lost data
Common Mistakes When Converting JPG to BMP
"Converting JPG to BMP will improve the quality"
No. JPG has already permanently discarded data during compression. Converting to BMP preserves what's left but cannot restore lost detail. The file will just be larger.
"BMP will be smaller than my JPG file"
BMP uses no compression, so the output file is often larger than a lossy JPG. If you need a small file, BMP may not be the right choice.
Frequently Asked Questions
Why won't my JPG file open?
JPG files may not open if your device lacks the right codec or application. Converting to BMP — a more widely supported format — usually resolves this. BMP is an uncompressed raster format that preserves every pixel but produces very large files.
Is it safe to convert JPG to BMP online?
Yes. CocoConvert encrypts your file via TLS, processes it on isolated servers in Germany, and permanently deletes it within 24 hours. Your files are never shared or analysed.
Will I lose quality converting JPG to BMP?
Converting JPG to BMP maintains high quality with CocoConvert's optimised encoder settings. CocoConvert uses high-quality encoder defaults to preserve as much fidelity as possible.
How large can my JPG file be?
Free users can convert files up to 250 MB each. Pro users get a 5 GB limit per file, and Business API users have custom limits.
Can I convert JPG to BMP on my phone?
Absolutely. CocoConvert works in any modern browser — iOS Safari, Android Chrome, and all desktop browsers. No app required.
