Why Verify Your PNG Files?

File extensions can be misleading. A file named 'image.png' might actually be a JPEG or a WebP file with a changed extension. Our PNG verifier looks deep into the file structure (the magic bytes) to ensure it is a valid Portable Network Graphics (PNG) file.

  • Confirms the actual file signature (89 50 4E 47 0D 0A 1A 0A).
  • Checks for proper IHDR and IEND chunks.
  • Identifies if transparency (alpha channel) is present.
