GeoTIFF to BMP Converter
Processing entirely on your device — large files may take a moment.
GeoTIFF and Bitmap Image exist for different jobs: GeoTIFF is a TIFF that carries its geography: embedded tags map every pixel to real-world coordinates and projection (EPSG codes), making it the standard interchange format for satellite imagery, drone orthomosaics and GIS raster layers. Some legacy Windows programs, industrial devices and printers still require plain, uncompressed BMP files.
Because the whole conversion happens on your device, it is instant, unlimited and genuinely private — no accounts, no watermarks, no files on anyone's server. Multiple files are converted in one go.

About the GeoTIFF format
GeoTIFF answers a question plain TIFF cannot: where on Earth is this pixel? It is a regular TIFF image plus a set of metadata tags — ModelPixelScale and ModelTiepoint map pixel rows and columns to projected coordinates, and GeoKeyDirectory stores the projection itself as EPSG codes (UTM zones, Web Mercator, national grids). The result is the de-facto standard for satellite scenes, Landsat/Sentinel downloads, drone orthomosaics, elevation models and every GIS raster layer that has to survive being emailed between software.
Because the geography lives in TIFF tags, the pixel data is ordinary imagery — which means converting GeoTIFF to PNG, JPG or WebP is really just decoding a TIFF and dropping the map metadata. That is exactly what you want for previews: a web page, a slide deck or a chat message has no idea what an EPSG code is, but it will happily show the image. What you lose in the conversion is the georeference itself, so keep the original .tif whenever the file feeds back into QGIS or ArcGIS.
+ Strengths
- ✓Self-describing: image + coordinates + projection in one file
- ✓Read by every GIS tool (QGIS, ArcGIS, GDAL, Google Earth)
- ✓Supports 16-bit, float, multi-band and tiled storage
! Limitations
- −Converting to PNG/JPG discards the georeference
- −Files are large — TIFF has no strong compression by default
- −Overkill for images that never touch a map
About the BMP format
BMP is Windows' native bitmap format, dating to 1990. It stores pixels essentially raw — rows of BGR values padded to 4-byte boundaries — with optional RLE compression that almost nobody uses. That simplicity is its whole personality: any program written since the dawn of Windows can read one in a dozen lines of code, which is why scanners and ancient lab software still emit it.
The cost of that simplicity is size: an uncompressed BMP of a photo runs dozens of times larger than a JPG. There is no meaningful metadata standard, transparency only exists via the rarely-implemented V5 header, and no modern workflow needs it. Treat BMP as a legacy interchange format you convert away from.
+ Strengths
- ✓Zero compression artifacts — pixels stored as captured
- ✓Trivially easy to decode, even in ancient software
- ✓Universal inside the Windows world
! Limitations
- −Enormous files — dozens of times larger than JPG
- −No real metadata or color-management story
- −No role in modern web or print workflows
Why convert GeoTIFF to BMP?
There is a concrete reason this conversion exists: Converting to PNG/JPG discards the georeference BMP sidesteps that — Zero compression artifacts — pixels stored as captured If that is your situation, the tool above settles it in seconds, entirely on your device.
Frequently asked questions
Is this GeoTIFF to BMP converter really free?
Yes — completely free, with no sign-up, no watermark and no daily conversion limits. The site is supported by advertising.
Are my files uploaded to a server?
No. The conversion runs entirely inside your browser using WebAssembly, so your files never leave your device — that is what makes it instant and private.
Does it work on Windows, Mac, iPhone and Android?
Yes. Anything with a modern browser works: Windows, macOS, Linux, Android and iOS. No software installation is required.
Will I lose quality converting GeoTIFF to BMP?
No — BMP is a lossless format, so every pixel of the converted image matches your original GeoTIFF file. You can also adjust the quality/size balance before converting when the target format supports compression.
What happens to EXIF data and other metadata?
Conversions here re-encode the image, and re-encoding generally does not carry the original metadata over. If the EXIF data of your GeoTIFF files matters (camera model, GPS, timestamps), keep the original file as the master and treat the converted copy as the shareable version.
Will transparent areas survive the conversion to BMP?
Transparency is kept whenever BMP actually supports an alpha channel. If the target format has none (like JPG), transparent areas are flattened onto a white background — that is a property of the format, not of this tool.
