Multiple source images
Only one image is decoded; a concatenated image sequence is not exported as a complete set.

What happens when you convert ICO to PPM?
Opaque output
Transparency is replaced with white by default. Change the background in Advanced options.
Lossless sample storage
Netpbm stores these samples without compression. Reducing colour, thresholding or changing maxval can still lose information before storage; text and binary representations change the layout, not its image meaning. PPM can store its supported image samples without lossy compression. This applies after rendering and sample conversion: it does not guarantee preservation of source precision, colour space or document structure, and cannot undo earlier losses.

Good choice when
- PPM fits your delivery use: RGB processing & debugging.
- You can choose the source image or part needed for delivery.
- An opaque image is acceptable for your destination.
- You need lossless storage of the rendered samples supported by PPM.
Probably not when
- You require a complete collection, page set or multipart round trip.
- You need cutouts or translucent edges for compositing.
- You expect lossless encoding to restore lost details or editing structure.
- You require identical samples without a defined colour and precision policy.

- Lossless sample storage
- Netpbm stores these samples without compression.

- Sample precision & colour
- Pixel conversion only. Original EXIF, GPS, XMP and ICC profiles are not copied; processing uses 8-bit display pixels.
- Metadata & colour
- Pixel conversion only. Original EXIF, GPS, XMP and ICC profiles are not copied; processing uses 8-bit display pixels.
- Compression
- ICO: Depends on variant → PPM: Uncompressed ICO: ICO compression depends on the embedded image payload. Multiple sizes are alternatives, not animation frames; transparency handling differs between old masks and alpha-capable images. PPM: Netpbm stores these samples without compression. Reducing colour, thresholding or changing maxval can still lose information before storage; text and binary representations change the layout, not its image meaning.
- Transparency
- Transparency is replaced with white by default. Change the background in Advanced options.
- Colour depth
- PPM: maxval up to 65535
- Multiple images
- ICO: Alternative icon sizes
- Dimensions
- Rendered image dimensions are retained within the converter limits; this tool does not offer resizing. Orientation handling depends on the source decoder.
- Metadata
- Pixel conversion only. Original EXIF, GPS, XMP and ICC profiles are not copied; processing uses 8-bit display pixels.
Common questions
Will every source image be exported?
Only one image is decoded; a concatenated image sequence is not exported as a complete set.
What happens to transparent areas?
Transparency is replaced with white by default. Change the background in Advanced options.
Does lossless output mean an unchanged source?
Netpbm stores these samples without compression. Reducing colour, thresholding or changing maxval can still lose information before storage; text and binary representations change the layout, not its image meaning. PPM can store its supported image samples without lossy compression. This applies after rendering and sample conversion: it does not guarantee preservation of source precision, colour space or document structure, and cannot undo earlier losses.
Are bit depth and colour values guaranteed to match?
Pixel conversion only. Original EXIF, GPS, XMP and ICC profiles are not copied; processing uses 8-bit display pixels.
Will metadata and colour profiles be retained?
Pixel conversion only. Original EXIF, GPS, XMP and ICC profiles are not copied; processing uses 8-bit display pixels.
