GeoTIFF to TAR.GZ Converter
Processing entirely on your device — large files may take a moment.
GeoTIFF and Gzipped TAR Archive 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. TAR.GZ is what open-source projects and Linux servers expect to receive.
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 TAR.GZ 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 TAR.GZ?
There is a concrete reason this conversion exists: Converting to PNG/JPG discards the georeference TAR.GZ sidesteps that — Universally understood on Unix-like systems If that is your situation, the tool above settles it in seconds, entirely on your device.
Frequently asked questions
Is this GeoTIFF to TAR.GZ 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 TAR.GZ?
No — TAR.GZ 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.
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.
Will transparent areas survive the conversion to TAR.GZ?
Transparency is kept whenever TAR.GZ 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.
