Fast, secure PNG to PCX conversion. No registration required.
Here is the short version — PNG is the lossless image standard with alpha-channel transparency and deflate compression. Hence the need for PCX. Need a PCX for a CMS, a chat message or an email client that politely refuses PNG? This tool re-encodes your image in the background and returns a drop-in PCX replacement. No registration, no watermark, no visual change beyond what the PCX encoder itself introduces. Background. PNG is the lossless image standard with alpha-channel transparency and deflate compression. Destination side, PCX is the legacy ZSoft/PC Paintbrush bitmap format from the DOS era.
PNG Image
Source formatPNG is a lossless image format that supports transparency. It is ideal for graphics, logos, screenshots, and any image where preserving exact pixel data is important.
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 PNG to PCX
Converting keeps the picture recognisable end-to-end while changing the container that ships it. PCX typically wins on one of three fronts: broader software support, smaller files for the same visual quality, or features like transparency that PNG cannot express. The conversion itself is fast because both sides are raster formats.
HOW TO CONVERT
PNG → PCX
Upload your PNG
Start by dropping the PNG onto the uploader. Files up to 25 MB go through on the free tier without registration; paid plans go up to 2 GB.
Conversion happens server-side
Our imagemagick-based pipeline reads the PNG pixel grid, preserves resolution and colour profile, and encodes a clean PCX.

Common Use Cases
Share across platforms
Send PCX files to anyone without worrying about whether they have the right software for PNG.
Embed in documents
Drop PCX output into Word, Google Docs, PowerPoint, Notion or a website without conversion warnings.
Optimize size
PCX often produces smaller files than PNG for web, email and storage.
Archive & future-proof
Store in a widely-supported format that will still open on future operating systems without legacy plugins.
PNG vs PCX — Strengths and limitations
What each format does best, and where it falls short.
PNG Strengths
- Lossless compression — every save preserves the original pixels perfectly.
- Full 8-bit alpha channel for smooth transparency.
- Excellent for text, UI screenshots, logos, and line art.
- Royalty-free and an ISO standard (ISO/IEC 15948).
- Supports 16-bit color depth for high-fidelity work.
Limitations
- Much larger than JPEG for photographs (no perceptual compression).
- No native animation in most software (APNG support is inconsistent).
- No CMYK support — web and screen only, not print.
PCX Strengths
- Simple format — easy to parse in any language.
- RLE compression keeps flat-color images compact.
- Historic archive format for 1985-1995 PC art.
- Stable since 1985 with no breaking changes.
Limitations
- Legacy — no new content created as PCX in 2026.
- Inefficient for photographs (RLE is wrong algorithm).
- Limited to 24-bit color depth.

Quality & Compatibility
Converting keeps resolution, aspect ratio and colour profile identical to the source. Metadata (EXIF, XMP) transfers where PCX supports it; otherwise it is dropped. If the PNG contained an alpha channel and PCX does not support transparency, the background is flattened to white by default.
Tips for Best Results
- When uploading to Retina / high-DPI contexts, render the PCX at 2× the CSS pixel size; the crispness gap over 1× is noticeable on modern screens.
- Strip EXIF metadata from the PCX before publishing if the PNG came from a phone camera — it often contains GPS coordinates and device IDs.
- If the PNG is a screenshot of text or UI, prefer a lossless PCX target to avoid the JPEG-style ringing around glyph edges.
Frequently Asked Questions
It depends on the codecs involved. If both PNG 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 PNG exactly, but cannot recover detail that PNG had already compressed away.
Often yes, especially when PCX is lossless. PNG 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.
