PCT is the DOS/Windows three-letter spelling of an Apple PICT picture, the classic Mac bitmap-and-vector image format. The .pct name exists only because early PCs limited extensions to three letters, so Mac PICT files had to drop a letter to cross over. Analyser handles .PCT alongside related formats such as .TGA, .QOI, .PPM and more. In Analyser's format library, .PCT sits in the Images category.

How do I open a .PCT file?

Drop a .PCT file onto Analyser at https://lab.valjdakosta.com/ and it is identified directly in your browser - no upload, no account and no software to install. Decode and preview extra still-image formats in pure JavaScript - Truevision TGA, QOI, Netpbm (PPM/PGM/PBM), PCX, farbfeld, WBMP, XBM/XPM, Sun Raster and SGI are fully rendered - and read header metadata from codec-heavy formats: Radiance HDR, DirectDraw Surface (DDS) game textures, OpenEXR, JPEG 2000, JPEG XR, EPS/PostScript, Windows WMF/EMF metafiles, Apple ICNS icons, CUR/ANI cursors, MNG and Lottie animations.

Can I open a .PCT file online for free?

Yes. Analyser is a free online .PCT identifier that runs entirely in your browser - your .PCT file never leaves your device, so there is nothing to upload and no software to install. It even works offline once installed.

What Analyser reads: Decode and preview extra still-image formats in pure JavaScript - Truevision TGA, QOI, Netpbm (PPM/PGM/PBM), PCX, farbfeld, WBMP, XBM/XPM, Sun Raster and SGI are fully rendered - and read header metadata from codec-heavy formats: Radiance HDR, DirectDraw Surface (DDS) game textures, OpenEXR, JPEG 2000, JPEG XR, EPS/PostScript, Windows WMF/EMF metafiles, Apple ICNS icons, CUR/ANI cursors, MNG and Lottie animations.
Depth of analysis: .PCT is an identification-grade format: Analyser recognises it from its bytes and decodes the header metadata it carries, rather than opening it in a full viewer. Formats that do get a full viewer are marked "Full" on the formats page.
Open a .PCT file: Drag a .PCT file onto the Analyser home page (or tap to pick one). It is identified entirely in your browser - nothing is uploaded, there is no account, and it works offline once installed.
