Remove metadata from GIF
See every hidden field in your GIF image, then strip it — with the pixels copied through untouched.
Where GIF keeps its metadata
GIF has no EXIF. What it does have are Comment extension blocks and Application extension blocks, where editing tools leave their name and occasionally more.
How we remove it
Comment and non-essential application blocks are removed while the image descriptors and LZW-compressed frame data are copied straight through.
Worth knowing about GIF
- The Netscape looping extension is technically an application block, so it is explicitly preserved — removing it would break looping on animated GIFs.
- GIF is the lowest-risk format here. It cannot carry GPS or camera data, only whatever a tool chose to write into a comment.
- Frame timing and the global colour table are untouched, so the animation plays identically.
Other formats
The same engine handles JPG / JPEG, PNG, WebP, HEIC / HEIF, AVIF, TIFF, MP4 and MOV.
Questions
Frequently asked questions
Does removing metadata change my GIF file's quality?
No. Comment and non-essential application blocks are removed while the image descriptors and LZW-compressed frame data are copied straight through. After each removal we re-read the finished file and, where the browser can decode both, compare every pixel against the original to prove nothing changed.
Where is metadata stored inside a GIF file?
GIF has no EXIF. What it does have are Comment extension blocks and Application extension blocks, where editing tools leave their name and occasionally more.
Is my GIF file uploaded?
No. The file is parsed and rewritten by JavaScript on your own device. There is no upload endpoint, so there is also no size cap and no queue.
Can I clean several GIF files at once?
Yes. Drop as many as you like and download them back as a single ZIP. Files are processed one after another, so memory stays flat no matter how big the batch is.
