What You Need to Know About PPM to PGM
How does the PPM to PGM conversion work technically?▼
Xonvert uses WebAssembly-compiled libraries to decode your PPM file in-browser, process the image data, and re-encode it as PGM. All processing happens on your device's CPU.
What happens to my files after conversion?▼
Nothing — your files exist only in your browser's memory during conversion. Once you close the page, all data is cleared. No files are stored anywhere.
What is PPM format?▼
PPM Color Image is Portable Pixmap format for simple RGB color images. It is primarily used for color image processing pipelines and academic imaging. Part of the Netpbm family — full-color RGB variant
Will the conversion strip my EXIF or metadata?▼
Xonvert preserves metadata (EXIF, XMP, ID3, etc.) when the target PGM format supports it. You can optionally strip metadata in the settings for smaller, cleaner output files.
Does the conversion preserve metadata?▼
Xonvert preserves compatible metadata fields when converting between formats. Some format-specific metadata may not carry over if the target format doesn't support it.
Can I share the converted PGM file directly?▼
Yes. After conversion, you can download the PGM file and share it via email, messaging apps, cloud storage, or any other method you prefer.
Does converting PPM to PGM change the resolution?▼
No. The original resolution is preserved by default. You can optionally resize in the settings panel if you need different dimensions.
