Some forums, chat tools, email signatures and older programs still ask for GIF. If that is the format you need, this converts a JPG to a GIF in a few clicks, with every file keeping its name.
Be aware of what GIF does to photographs. It holds at most 256 colours, and a JPG photo contains thousands, so skies, skin and shadows can show visible steps, called banding. GIF also compresses photos poorly, so the file is often several times larger than the JPG. JPG has no transparency, so the GIF is a normal opaque image. The result is a single still frame, not an animation.
The pixel dimensions never change, each file keeps its name with only the extension swapped, and no metadata or watermark is added. Everything runs in your browser, so your images are never uploaded.
If you are choosing a format for a photograph, GIF is rarely the right answer. Use it when a system specifically requires it, such as an old forum, a legacy email signature or a program that only reads GIF. If you are not sure, convert one file first and look at it at full size before converting the rest.
Tip: GIF suits simple graphics much better than photographs. If you only need to share or post a photo, keep the JPG or use WebP.
GIF stores at most 256 colours. A photo has thousands, so the converter picks 256 and smooth gradients turn into visible steps.
GIF compresses photographs poorly, and JPG is built for them. A GIF of a photo is often several times larger.
No. The result is one still image.
No. A JPG has no transparency, so the GIF is a normal opaque image.
Yes. Add them all, convert once and download a single ZIP. Only the extension changes. A file named holiday.jpg becomes holiday.gif.
No. The conversion happens in your browser and the files never leave your device.
