What is a .PNG file?
PNG is a lossless image format with full alpha transparency, ideal for graphics, screenshots and logos.
- Did you know
- PNG was created in 1996 as a free replacement for GIF, after a patent dispute over the LZW compression GIF used.
- PNG’s creators left a playful Easter egg in early drafts, joking the name could be read recursively as “PNG’s Not GIF”.
- Mozilla engineers devised the Animated PNG (APNG) extension in the mid-2000s, but it was only folded into the official PNG specification decades later.
- On the web a .PNG file is served with the MIME type
image/png. - Analyser spots a .PNG file by its signature bytes
89 50 4E 47- the next three bytes spell "PNG".
- What Analyser shows you
- View EXIF, GPS, camera settings, histograms, dominant colours, OCR text, and AI-generation markers in JPG, PNG, HEIC, WebP, GIF, BMP, TIFF, AVIF and JPEG XL images. Detects computational-photo wrappers (Apple Live Photo, Google and Samsung Motion Photo, Ultra HDR gain maps), opens THM movie-thumbnail files, and extracts every embedded image from multi-image files - all sizes in an ICO, both halves of an MPO stereo pair, and every page of a multi-page TIFF.
- Open a .PNG file
- Drag a .PNG file onto the Analyser home page (or tap to pick one). It opens entirely in your browser - nothing is uploaded, there is no account, and it works offline once installed.
