What is a .EPSI file?

EPSI is an Encapsulated PostScript Interchange file - an EPS that carries its preview as plain ASCII hex so it survives text-only transfers.

Did you know: EPSI dates from when email and FTP could mangle binary data, so even the preview thumbnail was stored as printable text.
Analyser handles .EPSI alongside related formats such as .TGA, .QOI, .PPM and more.
In Analyser's format library, .EPSI sits in the Images category.
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: .EPSI 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 .EPSI file: Drag a .EPSI 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.
