BMP to GIF Conversion FAQ
Does BMP to GIF conversion preserve transparency?
+
Transparency survives when GIF 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 GIF. GIF is CompuServe’s 1987 format, and the only reason it survived is that it animates.
Can I get transparency once the image is GIF?
+
The GIF format supports it, but the conversion cannot invent it. A BMP has no alpha channel, so every pixel including the background arrives fully opaque. Run /image-removebackground/ afterwards to cut the subject out — then the alpha channel GIF provides has something to store. GIF animation plays absolutely everywhere — email clients, forums, chat apps and browsers all render it with no codec negotiation.
What happens to EXIF metadata when converting BMP to GIF?
+
In most conversions, camera EXIF fields such as the camera model and GPS position are not carried into the GIF. 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 BMP files to GIF 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 BMP files private during conversion?
+
Yes. Uploaded BMP files are processed on our own conversion servers, no person reviews them, and they are never shared. The upload and the converted GIF 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 GIF file bigger or smaller than expected?
+
A BMP file with strong compression (heavily lossy JPG) often grows when re-encoded into a lossless GIF (PNG, TIFF), and a high-bitrate lossless BMP 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. GIF’s 256-colour ceiling wrecks gradients and video stills, and its file sizes for animation are an order of magnitude worse than WebP or MP4.
