ICO is the Windows icon container with multiple resolutions packed into one file. Reaching a PCX from there is one hop. Turn a ICO image into a PCX in seconds. The two formats share the same raster DNA so the visible quality is very close; what changes is how the file is packaged, which matters for browsers, editors and CMS uploaders. KaijuConverter runs the conversion server-side and deletes both files within two hours. Background. ICO is the Windows icon container with multiple resolutions packed into one file. Destination side, PCX is the legacy ZSoft/PC Paintbrush bitmap format from the DOS era.
ICO Icon
Source formatICO is the icon file format used for favicons and Windows application icons. A single ICO file can contain multiple image sizes and color depths for different display contexts.
PCX Image
Target formatPCX (PiCture eXchange) is a legacy raster image format created by ZSoft for their PC Paintbrush program. It was one of the first widely supported image formats on IBM PC compatibles and uses simple run-length encoding compression.
Why convert ICO to PCX
The real reason to move from ICO to PCX is almost never picture quality — both raster formats store essentially the same pixels. It is about the tools downstream: which editors open the file natively, which CMSes upload it without transcoding, which social platforms accept it. Picking PCX solves those edge cases at the cost of a short conversion step.
HOW TO CONVERT
ICO → PCX
Provide the ICO
Click or drag to upload. We accept a single ICO file per job, with an optional queue of additional images for batch mode.
Encode to PCX
The conversion decodes the ICO, resolves the colour space to sRGB and writes the PCX container around the pixel data.
Save the PCX
The download is streamed back over HTTPS. If you uploaded multiple files, a ZIP with all PCX outputs is produced instead.
Common Use Cases
Document embeds
Word, Google Docs and Pages embed PCX with correct aspect ratio; ICO may appear as a broken image icon.
Printer-friendly export
Consumer and office printers drive PCX through their print spoolers with no additional drivers.
Presentation slides
PowerPoint and Keynote treat PCX as a first-class citizen; ICO may need manual re-insertion per slide.
Online form uploads
Identity verification, job applications and legal forms often list PCX as the only accepted image format.
Quality & Compatibility
ICO-to-PCX conversion does not change the visible content. Quality is capped by the ICO decode; re-encoding a lossy source at high quality cannot recover detail that was already discarded. For archival masters, keep the original ICO alongside the PCX copy.
Tips for Best Results
- Large ICO files may look identical to small PCX files for photographic content; pick quality based on end use, not headline megapixels.
- For print, export PCX at 300 DPI minimum and check that the colour profile embedded matches the print shop specification.
- Batch-convert related ICO images in one pass so they share identical encoder settings and look consistent side-by-side.
Frequently Asked Questions
Frequently Asked Questions
It depends on the codecs involved. If both ICO and PCX are lossy, the pixels are re-encoded and a small amount of detail is discarded — invisible at default quality settings on photographs. If PCX is lossless (PNG, TIFF, BMP) the output keeps every pixel of the decoded ICO exactly, but cannot recover detail that ICO had already compressed away.
Often yes, especially when PCX is lossless. ICO tuned for efficient web delivery will usually produce smaller files than PCX's default settings. If file size matters, drop the quality in Advanced or pick a more compressed target format instead.
KaijuConverter uploads over HTTPS, processes the image in an isolated container and deletes both the source and the output within two hours. No account is required, file contents are never logged, and we do not use uploads to train any model. For confidential material, the paid plan includes a data-processing agreement.
