How do I open a .FLIF file?

Drop a .FLIF 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 .FLIF file online for free?

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

What is a .FLIF file?

FLIF (Free Lossless Image Format) is a lossless codec that aimed to beat PNG, lossless WebP and lossless JPEG 2000 on size. Created by Jon Sneyers.

Did you know: A FLIF is progressive in a special way - stop downloading at any point and you still get a complete, lower-detail version of the whole image.
Analyser handles .FLIF alongside related formats such as .TGA, .QOI, .PPM and more.
In Analyser's format library, .FLIF 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: .FLIF 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 .FLIF file: Drag a .FLIF 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.
