How to Convert Multiple GEOTIFF Files to PPM?
1. Download and Install reaConverter
First, grab reaConverter from the download button below. Installation is fast, and the software runs offline — no account or signup needed.
2. Load your GEOTIFF files
Add GEOTIFF files to reaConverter. One file or a thousand, the process is the same. Everything runs locally on your machine.
You can drag-and-drop files, browse to a folder, or add entire directory trees including subfolders.
3. Select PPM as output format
Select PPM from the output format list and set your destination folder. You can also adjust quality and compression settings.
4. Start GEOTIFF to PPM conversion
Click the Convert button to start. reaConverter will process all your files with the settings you selected.
When finished, your new .ppm files will be waiting in the destination folder.
How GEOTIFF and PPM differ in practice
GEOTIFF describes geometry rather than pixels, so it has no inherent resolution. The conversion renders it at whatever size you choose, and that choice is final: enlarging the PPM afterwards will not recover the sharpness. Set the output dimensions or DPI before converting, not after. One GEOTIFF file can hold several pages or frames, while PPM holds one image each. reaConverter writes a separate output file per page and numbers them, so a single input can produce a whole folder of results.
