Convert JFIF to BMP
JFIF is a JPEG variant that Windows and Chrome sometimes save. It is technically the same as a JPG. BMP is the practical destination when JFIF is the thing standing in the way, because BMP is built for legacy Windows software and raw pixel data and almost every program opens it. Worth knowing before you start: BMP is lossless, so it preserves exactly the pixels that came out of the JFIF file. It cannot restore detail the JFIF encoder already discarded, and the file will usually get larger, not smaller. The conversion runs entirely in your browser: there is no upload, no file size limit and no watermark on the result.

Why convert JFIF to BMP?
JFIF is the original container name for JPEG files, and Windows or Chrome occasionally save images with the .jfif extension. The data inside is regular JPEG, but the unusual extension confuses many apps and upload forms. Renaming sometimes works, converting guarantees a file every tool accepts.
BMP stores pixels with little or no compression, which makes files huge but trivially simple to read. It is mostly seen in legacy Windows workflows, screenshots from older tools and some scientific software. Converting to a compressed format usually shrinks a BMP by 90 percent or more.
JFIF vs BMP at a glance
| JFIF | BMP | |
|---|---|---|
| Full name | JPEG File Interchange Format | Bitmap image |
| Compression | Lossy (JPEG data) | Uncompressed |
| Transparency | No | No |
| Best for | Legacy JPEG files saved by Windows or Chrome | Legacy Windows software and raw pixel data |
What changes when you convert JFIF to BMP
| What happens | |
|---|---|
| Image quality | Unchanged from here on. BMP is lossless, so it preserves exactly the pixels decoded from the JFIF file. It cannot restore what the JFIF encoder already discarded. |
| Transparency | JFIF has no alpha channel, so there is no transparency to lose. |
| EXIF and GPS | Removed. The conversion goes through a pixel buffer, so camera data and location are not carried into the BMP file. |
| Colour profile | Not carried across. The image is handled in sRGB, which is right for the web and wrong for colour-managed print work. |
| Animation | Not applicable. JFIF files here are single images. |
| File size | Much larger. A 24 bit BMP costs three bytes per pixel regardless of content, so the file size is fixed by the dimensions alone. |

Frequently asked questions
What is a JFIF file?
JFIF is a JPEG variant that Windows and Chrome sometimes save. It is technically the same as a JPG.
What is a BMP file?
BMP is an uncompressed Windows bitmap that keeps full pixel detail at a large file size.
Is it free to convert JFIF to BMP?
Yes. There are no limits, no watermarks and no account needed. Convert as many JFIF files as you like.
Are my files private?
Completely. Your JFIF files never leave your browser and are never uploaded to a server, so your images stay on your device.
