Change standard JPG pictures into GIF format safely and locally.
JPG is the most common file extension for images compressed with the JPEG standard, published in 1992. It applies lossy compression based on the discrete cosine transform, splitting images into small blocks and discarding visually insignificant detail to shrink file size. The compression level is adjustable: higher quality keeps more detail at a larger size, while lower quality trades visible artifacts for a much smaller file. JPG supports 24-bit true color and embeds Exif metadata such as camera model and capture date. Its biggest strength is universal compatibility — it is the native output of virtually every camera and phone, and opens in every browser, viewer, and operating system without exception.
GIF (Graphics Interchange Format) was introduced by CompuServe in 1987 as a platform-independent format for sharing color graphics over slow, modem-speed connections. It uses lossless LZW compression on indexed images limited to a palette of 256 colors, and its defining feature is native support for simple looping animation, storing several frames with their own timing directly inside one file. GIF also supports single-color binary transparency. Even though modern formats like WebP and AVIF now offer full-color animation with much better compression, GIF's near-universal support in browsers, chat apps, and social platforms keeps it firmly embedded in everyday web culture.
Transforming standard compressed JPEGs into GIF format allows usage on legacy web platforms restricted to 8-bit color assets.
GIF limits colors to a maximum of 256, so some photographic details may look dithered.
No, processing is 100% client-side.
Yes, this tool is completely free with no registration, no watermark, and no conversion limit.
No, the conversion happens locally in your browser using JavaScript. Your files are never uploaded to any external server.
There's no fixed limit enforced by the tool since everything runs in your browser rather than on a server.
For most everyday uses, the visual difference is negligible.
