PNM to CUR Converter
Processing entirely on your device — large files may take a moment.
Portable Anymap and Windows Cursor exist for different jobs: PNM is the umbrella of the netpbm family — P1-P6 auto-detected, covering bitmap, graymap and pixmap in one extension. Tools that say "PNM" accept all of them. Converting CUR to PNG lets you view and reuse cursor graphics in design tools.
This converter runs entirely in your browser using WebAssembly — your files never leave your device, nothing is uploaded, and there are no watermarks, sign-ups or queues. Drop in several files at once to convert them as a batch.

About the PNM format
PNM is not a format of its own — it is the family name for PBM/PGM/PPM, and files carrying the .pnm extension simply expect the reader to sniff the P1-P6 magic and branch accordingly. It exists because Unix tools always preferred one extension that means "any of these".
This converter auto-detects the member format on input and writes the full-color P6 flavor on output, so a .pnm file turns into anything modern without a separate PBM/PGM/PPM detour.
+ Strengths
- ✓One extension for the whole netpbm family
- ✓Auto-detection on both read and write
- ✓Same bulletproof simplicity as PBM/PGM/PPM
! Limitations
- −Ambiguous by design — tools must sniff
- −Inherits all the size downsides of the family
- −Some tools only accept specific members
About the CUR format
CUR is the Windows cursor file: structurally identical to ICO (several small bitmap sizes bundled), with the addition of a hotspot coordinate that marks which pixel is the pointer's tip. Windows ships most of its system cursors as CUR files.
Designers customizing cursors or extracting UI assets meet CUR files that no modern image tool opens. Converting to PNG (the largest embedded size) makes them editable, viewable and reusable in web apps that implement custom cursors.
+ Strengths
- ✓Windows cursor standard
- ✓Multiple sizes in one file
- ✓Hotspot data travels with the image
! Limitations
- −Tiny sizes only (usually ≤48px)
- −Meaningless outside cursor use
Why convert PNM to CUR?
Converting makes sense where the strengths of CUR meet what PNM cannot give you. Windows cursor standard Meanwhile Ambiguous by design — tools must sniff One pass through the converter above puts your file on the right side of that trade-off.
Frequently asked questions
Is this PNM to CUR converter really free?
Yes — completely free, with no sign-up, no watermark and no daily conversion limits. The site is supported by advertising.
Are my files uploaded to a server?
No. The conversion runs entirely inside your browser using WebAssembly, so your files never leave your device — that is what makes it instant and private.
Does it work on Windows, Mac, iPhone and Android?
Yes. Anything with a modern browser works: Windows, macOS, Linux, Android and iOS. No software installation is required.
Will I lose quality converting PNM to CUR?
No — CUR is a lossless format, so every pixel of the converted image matches your original PNM file. You can also adjust the quality/size balance before converting when the target format supports compression.
Can I convert several PNM files at once?
Yes — drop as many files as you like into the tool and they are converted in one batch. When more than one file comes out, everything is bundled into a ZIP for a single download.
Will transparent areas survive the conversion to CUR?
Transparency is kept whenever CUR actually supports an alpha channel. If the target format has none (like JPG), transparent areas are flattened onto a white background — that is a property of the format, not of this tool.
