JPG to GIF Converter

Turn JPG photos into GIF images: convert each photo into its own GIF for a site or program that only takes GIF, or combine several photos into an animated GIF — a before-and-after, a product from several angles, a little slideshow. Everything is done in your browser with a palette made for each photo, and nothing is uploaded.

How to use this tool

1. Choose what to make: automatic, one animation, or one GIF per photo.
2. For an animation, set the time per frame, the looping and the order.
3. Pick the maximum width, the background colour for photos of another shape, and the colours.
4. Choose the photos; the GIF appears right away. Download it (several GIFs come as one ZIP).

Formula

Loop length = number of photos × time per frame

GIF can show only 256 colours per frame, so each photo gets its own palette chosen from its pixels and refined to their average colours. Dithering mixes neighbouring colours to hide banding in skies and skin. In an animation the first photo sets the width and height; other photos are fitted inside on the background colour. Identical photos in a row are merged into one longer frame.

Example

6 photos at 750 ms each loop every 6 × 0.75 = 4.5 seconds. At "Up to 640 px", 4000 × 3000 phone photos are reduced to 640 × 480 before conversion, so the animated GIF is usually 1–2 MB instead of tens of megabytes.
