Why Verify Your GIF Files?

Graphics Interchange Format (GIF) files have a distinct structure starting with a version signature (GIF87a or GIF89a). Our GIF verifier checks these signatures and the logical screen descriptor to confirm validity.

  • Confirms GIF signatures (47 49 46 38 37 61 or 47 49 46 38 39 61).
  • Checks for animation loops and frame delays.
  • Identifies color palette size and transparency index.
