How this service works
Read a GIF's version, width, height and global colour table size from its first 13 bytes.
Output
Returns a structured object including GIF version (e.g. GIF87a or GIF89a), image width and height in pixels, whether a global colour table is present, number of global colours, colour resolution bits, background colour index, pixel aspect ratio byte, and the number of bytes examined. May also include a summary, verdict, reasons, and degraded/disclaimer flags if the input is incomplete or malformed.
Example use cases
Verify GIF dimensions before upload
“I have a GIF file and want to confirm its width and height before uploading it. Here are its first 13 bytes as hex: 47494638396180007000f70000 — can you parse the header and tell me the dimensions?”
Identify GIF version in media pipeline
“I need to know if this GIF is GIF87a or GIF89a before processing it. The first 13 bytes in hex are 474946383961c800c800f70000 — can you extract the version from the header?”
Audit GIF colour table in forensic review
“I'm reviewing a suspect GIF file and need to know its global colour table size and colour resolution bits. Here are the first 16 bytes in hex: 474946383961200020008700ff — can you break down the header fields?”
Technical details
Endpoint
GEThttps://file-formats.x402tookit.com/gif-header?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need to extract structured metadata from the GIF file format header — version, dimensions, and colour table details — without fully decoding the image. Prefer this over generic file-type detection endpoints when you already know the file is a GIF and need its specific header fields. It is faster and cheaper than full image decoding libraries for header-only inspection tasks.
Side effects
- Fewer than 13 hex bytes provided — returns null or partial fields
- Invalid hex string causes parsing failure
- Non-GIF magic bytes result in version/fields returning null
- Truncated or corrupted header may set degraded flag and return partial data
