PNG to PNM Java Overview
Convert PNG images to Portable Any Map (PNM) formats for simple, interoperable raster output (PBM/PGM/PPM). Use general image controls to set resolution (DPI), select scaling behavior, and define exact width/height for predictable results across inputs. Choose grayscale or RGB output as appropriate, and map transparent regions to a specified background color when downstream tools lack alpha support. Ideal for processing pipelines, testing, and archival workflows that require lightweight, uncompressed files with consistent characteristics.

Customizable Parameters
Fine-tune your automation with these powerful conversion options
File
File Supported formats: .pngFile to be converted. Value can be URL or file content.
ImageResolution
Integer Default: 200Set output image resolution in dpi.
Range: 10 .. 800ScaleImage
Bool Default: TrueScale the output image. If ScaleImage is False output document will be stripped to ImageHeight / ImageWidth, if ScalePage is True output document will be scaled to ImageHeight / ImageWidth.
ScaleProportions
Bool Default: TrueIf set to true, the barcode will be generated using recommended proportions based on the larger dimension.
ScaleIfLarger
Bool Default: FalseScaling only if the input image is larger than the output.
ImageHeight
IntegerImage height in pixels.
Range: 10 .. 20000ImageWidth
IntegerImage width in pixels.
Range: 10 .. 20000ImageInterpolation
Bool Default: FalseSpecifies whether the image parser should use image interpolation. Enabling image interpolation will result in higher quality for scaled images at the expense of speed.
TransparentColor
ColorAdd alpha channel to image, setting pixels matching color to transparent. Values accepted are RGBA, CMYK hex string, color name or RGB format like this 255,255,255 (RED=255, GREEN=255, BLUE=255) or 255,255,255,150 with alpha chanel.
StoreFile
Bool Default: FalseWhen the StoreFile parameter is set to True, your converted file is written to ConvertAPI’s encrypted, temporary storage and made available via a time-limited secure download URL, valid for up to 3 hours. After this period, the file is permanently deleted.
When StoreFile is set to False, conversion happens entirely in-memory. The raw file bytes are streamed back in the API response without touching disk or external storage, ensuring maximum security and zero persistence so that only you can access the content.
