POT to PGM Converter
Export POT template slides to PGM grayscale images online
Grayscale Precision
PGM captures up to 16-bit tonal depth per pixel. Your POT slide renders retain smooth gradients and accurate luminance detail without color overhead.
Server-Side Processing
Rendering happens entirely in the cloud — your device uploads the POT template and downloads the PGM results, with zero local CPU or memory strain.
Cross-Platform Access
Run the converter from any browser on any operating system. Windows, macOS, Linux, and mobile platforms all work seamlessly.

Frequently Asked Questions
PGM captures grayscale intensity without color data. It suits scientific imaging, image processing pipelines, and situations where you need tonal information from slides without the overhead of color.
GIMP, Photoshop, IrfanView, and XnView all read PGM. On Linux, most default image viewers handle it natively since PGM belongs to the widely supported Netpbm format family.
PBM stores black-and-white only. PGM stores grayscale with up to 65535 shades. PPM stores full RGB color. All three share the same simple Netpbm structure.
Yes — PGM supports up to 16-bit grayscale depth, which captures smooth tonal gradients far better than binary PBM.
No — convert POT to PGM directly without signing up. Free tier covers standard conversions with no registration barrier.
The output PGM images maintain the original slide aspect ratio and resolution, just rendered in grayscale instead of color.
