Image Analyzers

See what is really inside an image file - format, size, metadata and the problems it hides.

Check a photo with the JPG Analyzer, a graphic with the PNG Analyzer or an animation with the GIF Analyzer.

File lying about its extension? The Image Format Detector reads what it really is.

What an analyzer tells you

An analyzer reads the file byte by byte and reports what it finds - not just what the extension claims. That makes it the quickest way to debug an image that will not open, looks wrong or is bigger than it should be.

Dimensions

Width, height, aspect ratio and DPI

Colour

Bit depth, colour mode, alpha and ICC profile

EXIF metadata

Camera, lens, exposure, date and GPS

File structure

Chunks, frames, layers and compression

Animation

Frame count, delays and loop settings

Private

Common problems an analyzer finds

  • Wrong extension - a "PNG" that is really a WebP or JPG. Fix it with the matching converter, such as WebP to PNG.
  • Huge file, small picture - oversized metadata or no compression. Clean it up with Compress PNG or Compress JPG.
  • Photo shows up sideways - an EXIF orientation tag. The JPG Analyzer shows it.
  • Location leaks - GPS coordinates in a photo you want to share. Remove them with the EXIF Data Remover.

Frequently Asked Questions

Dimensions, file size, colour depth, colour mode, transparency, compression type and format version. Photos also show EXIF data such as camera model, exposure and date.

Yes. The JPG Analyzer and HEIC Analyzer show camera model, lens, exposure settings, capture date and GPS coordinates. The EXIF Viewer shows the same data in a simple list.

Use the Image Format Detector. It reads the file signature, so it spots a WebP saved as .jpg or a HEIC renamed to .png.

Yes. The GIF Analyzer shows frame count, total duration, frame delays, loop count and the size of every frame.

Check it with the ICO Analyzer. It lists every size and colour depth inside the icon, so a missing 16 or 256 px entry stands out. Rebuild it with the ICO converter if needed. Mac icons have their own ICNS Analyzer.

Use the Image DPI Checker. It shows the DPI, the print size and whether the image is sharp enough for A4 or photo prints, and sets 300 dpi without re-compressing.

JPG, PNG and APNG, GIF, WebP, AVIF, HEIC, JPEG XL, camera RAW, TIFF, BMP, TGA, DDS, SVG, EPS/AI, PSD, ICO, CUR/ANI and Mac ICNS. Each analyzer understands the details of its own format.

No. Every analyzer reads your file right in the browser, so it never leaves your device.
