Converting JPG to GIF reduces the image to a 256-color palette, which is almost always worse than the JPG it came from. The main reason to do this is compatibility with systems that specifically expect GIF, like legacy email clients, some forum software, and embedded displays.

GIF's palette constraint is brutal on photographs. Smooth gradients become obvious color bands, skin tones get blotchy, and fine detail disappears. Dithering helps but introduces its own grain. File size is often larger than the JPG because GIF's LZW compression struggles with quantized photo content.
GIF plays everywhere: every browser, every image viewer, every email client. Compatibility was never GIF's problem; quality is.
JPG (JPEG) is a 1992 lossy photo format that became the default way to store photographs on the web. It uses a discrete cosine transform plus quantization, tuned so that errors fall where human vision is least sensitive. No transparency, no animation, but excellent for photos at 70–90% quality.
GIF is a 1987 format limited to a 256-color palette. Its lasting relevance is support for simple animation, which kept it in the meme ecosystem after PNG replaced it for static images. GIF compression is lossless within its palette constraints but usually worse than PNG for the same image.
Rarely. JPG is already universally supported and looks much better than GIF for photographs. The main legitimate reasons are specific platforms that only accept GIF, or artistic palette-quantization effects.
Almost certainly yes for photographs. GIF is limited to 256 colors per frame, which causes banding in gradients and blotchiness in skin tones. JPG uses 16 million colors.

Yes. The converter runs entirely in your browser using WebAssembly. Your images are never uploaded, never sent to a server, and never leave your device.
There's no hard limit, but because everything runs in your browser you're bounded by available memory. Very large images (over a few hundred megapixels) can hit browser memory limits. Process in smaller batches if you run into issues.
