PRN to PNG JavaScript Overview
A PRN file holds a print job exactly as the driver would have sent it to the printer. PostScript jobs and image-only .prn files convert to PNG, while PCL, PCL XL and other non-PostScript printer languages do not. Each page is drawn on an opaque white background rather than a transparent one. PNG is lossless, so fine text, barcodes and hairline rules stay sharp.
Drop a .prn file into the form on this page, or run the same conversion from your code. There is an SDK for every language from C# to Go. Set the resolution in DPI, from the 200 DPI default up to 2000, to decide how sharp each page renders. Constrain the width or height to fit a documentation page.
The result is a clean PNG of each PRN page for knowledge bases, support tickets and test reports. Includes a ready-to-use JS module.

ImageResolutionH
Integer Default: 200Set output image horizontal resolution in dpi.
Range: 1 .. 2000ImageResolutionV
Integer Default: 200Set output image vertical resolution in dpi.
Range: 1 .. 2000ImageHeight
IntegerImage height in pixels.
Range: 10 .. 20000ImageWidth
IntegerImage width in pixels.
Range: 10 .. 20000StoreFile
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.
