GeoTIFF to TGZ Converter
Processing entirely on your device — large files may take a moment.
Convert TGZ exactly like TAR.GZ — unpack, repack or inspect. If your files are still in GeoTIFF format, this page is the shortcut: 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.
This converter runs entirely in your browser using WebAssembly — your files never leave your device, nothing is uploaded, and there are no watermarks, sign-ups or queues. Drop in several files at once to convert them as a batch.

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 TGZ format
TAR.GZ is the classic Unix distribution shape: a TAR bundle squeezed through gzip (DEFLATE-based). Every Linux package of source code, every Apache tarball, every data-science dataset arrives this way. Decompression is a pipeline — untar the gzip stream — and the format is understood everywhere Unix ideas went.
gzip compresses the whole archive as one stream, which keeps ratio decent for text-heavy trees but means reaching file #400 requires decompressing the previous 399. Modern alternatives (zstd) are faster at similar ratios, yet tar.gz remains the safest common denominator.
+Strengths
- ✓Universally understood on Unix-like systems
- ✓Good ratio for text and source trees
- ✓Preserves Unix permissions via TAR
!Limitations
- −Single stream — no random access
- −Slower than modern zstd
- −Two-step format (tar + gzip)
Why convert GeoTIFF to TGZ?
Converting makes sense where the strengths of TGZ meet what GeoTIFF cannot give you. Universally understood on Unix-like systems Meanwhile Converting to PNG/JPG discards the georeference One pass through the converter above puts your file on the right side of that trade-off.
Frequently asked questions
Is this GeoTIFF to TGZ 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 TGZ?
No — TGZ 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.
Can I convert several GeoTIFF files at once?
Yes — drop as many files as you like into the tool and they are converted in one batch. When more than one file comes out, everything is bundled into a ZIP for a single download.
