BMP to TIFF Conversion FAQ
Does BMP to TIFF conversion preserve transparency?
+
Transparency survives when TIFF 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 TIFF. TIFF is the Tagged Image File Format from 1986, and it is the format scanning, publishing and archiving industries standardised on.
Can I get transparency once the image is TIFF?
+
The TIFF 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 TIFF provides has something to store. TIFF handles CMYK, 16-bit depth, embedded ICC profiles and multi-page documents, which is exactly what print and archival workflows require.
What happens to EXIF metadata when converting BMP to TIFF?
+
In most conversions, camera EXIF fields such as the camera model and GPS position are not carried into the TIFF. 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 TIFF 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 TIFF 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 TIFF file bigger or smaller than expected?
+
A BMP file with strong compression (heavily lossy JPG) often grows when re-encoded into a lossless TIFF (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. TIFF’s flexibility is its weakness — two TIFFs can be structured so differently that software reading one fails on the other — and files are large.
