GeoTIFF to DCX Converter
Processing entirely on your device — large files may take a moment.
GeoTIFF and Multi-page PCX 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. Convert images to DCX for legacy fax/document archives.
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.
How GeoTIFF compares to DCX
| GeoTIFF | DCX | |
|---|---|---|
| Structure | TIFF + GeoTIFF keys (ModelTiepoint/GeoKeyDirectory) | Multi-page PCX coder |
| Compatibility | QGIS, ArcGIS, GDAL, image viewers | ImageMagick, specialty tools |
| Best for | Satellite imagery, orthomosaics, elevation rasters | Legacy and specialty pipelines |

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 DCX format
The Multi-page PCX coder of the ImageMagick set — the fax-archive format is written natively by the magick.wasm engine, entirely in your browser.
Obscure coder formats like this are exactly what template-driven converters list and never actually convert — here it really works.
+ Strengths
- ✓Written natively by ImageMagick
- ✓Runs entirely in your browser
- ✓Free, private, no watermarks
! Limitations
- −Niche format — few modern readers
- −Feature subset varies by coder
- −Keep the original for re-editing
Why convert GeoTIFF to DCX?
There is a concrete reason this conversion exists: Converting to PNG/JPG discards the georeference DCX sidesteps that — Written natively by ImageMagick If that is your situation, the tool above settles it in seconds, entirely on your device.
Frequently asked questions
Is this GeoTIFF to DCX 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 DCX?
No — DCX 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 DCX?
Transparency is kept whenever DCX 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.
