JFIF to BMP Conversion FAQ
Does JFIF to BMP conversion preserve transparency?
+
Transparency survives when BMP is PNG, WebP, TIFF, GIF, or SVG. Converting to JPG flattens the alpha channel against a white background — if you need transparency, pick a transparency-aware target instead of BMP. BMP is the Windows Bitmap, the raw raster format built into Windows since 1985.
Does converting JFIF to BMP restore the quality that was lost?
+
No. The compression artefacts already baked into the JFIF are ordinary pixel data now, and BMP preserves them perfectly rather than removing them. The file usually gets larger, sometimes several times larger. It is still worth doing before editing, because further edits will not stack a second generation of loss on top. BMP needs no decoder library at all, so it remains the safe interchange format for embedded systems and legacy Windows tooling. The .jfif extension confuses Windows and many web apps into refusing the file, which is usually the only reason anyone converts it.
What happens to EXIF metadata when converting JFIF to BMP?
+
In most conversions, camera EXIF fields such as the camera model and GPS position are not carried into the BMP. There is no setting on this page to keep or remove metadata, so check the result with a metadata viewer if it matters.
Can I batch-convert hundreds of JFIF files to BMP at once?
+
Several files in one job need a paid plan. Free use is one file per conversion, one conversion an hour. On a paid plan you can add several files to one job, then download each result on its own or all of them in one ZIP.
Are my JFIF files private during conversion?
+
Yes. Uploaded JFIF files are processed on our own conversion servers, no person reviews them, and they are never shared. The upload and the converted BMP are both deleted automatically about 24 hours after the conversion, which leaves time to download the result. See /privacy/ for the full policy.
Why is my converted BMP file bigger or smaller than expected?
+
A JFIF file with strong compression (heavily lossy JPG) often grows when re-encoded into a lossless BMP (PNG, TIFF), and a high-bitrate lossless JFIF often shrinks dramatically when going to JPG/WebP. The ratio depends on the image content (photos compress differently from line-art or screenshots). BMP is gigantic — a 12-megapixel photo is around 36 MB — and no browser treats it as a sane web format.
