This turns a JPEG photo into a single still GIF. Worth saying plainly before you start, a JPEG to GIF conversion is almost never an upgrade. GIF is a much older format with a much smaller colour range, so you would normally only do this because something on the other end insists on a GIF and will not take anything else.
Your JPEG can hold millions of colours. A GIF holds 256, chosen per image. On a photograph that shows up as banding, those visible steps across a sky or a face where a smooth gradient used to be. On a flat logo, a chart or a screenshot of text, there were never that many colours to begin with, so the picture comes through looking fine.
People expect an old format to be small. It usually is not. GIF compression was built for flat areas of solid colour, and a photograph is the opposite of that, so a detailed image can come out heavier as a GIF than it was as a JPEG. The finished size sits next to the original on each row, so you can see it rather than guess.
A JPEG holds one still picture and nothing else, so there is no motion for a GIF to carry. The output is a single frame. If you were hoping to build an animation, that needs a source that already has multiple frames.
Palette picked per image
The 256 colours are chosen from your own photo rather than from a fixed set.
Dimensions left alone
Width and height come through exactly as they were in the JPEG.
Both sizes on the row
You can see whether the GIF actually came out smaller before you keep it.
Free to convert
There is no charge for a single image or for a whole folder of them.
JPEG to AVIF Converter
Re-compress JPEG photographs as AVIF files that are dramatically lighter at similar visible quality.
JFIF to JPEG Converter
Rename .jfif images to the .jpeg extension that every program and upload form recognises.
JFIF to GIF Converter
Convert .jfif images into still GIF files for older systems that accept nothing else.
JFIF to AVIF Converter
Turn .jfif images into far smaller AVIF files ready for a web page.
That is colour banding, and it is the palette limit showing. Photos with big smooth areas like skies and skin show it worst.
Not from a single JPEG. An animated GIF needs several frames, and one photograph only gives you one.
No. A JPEG has no transparency to pass on, so the GIF comes out fully opaque even though the format supports transparency.
Anything with flat colour and hard edges. Diagrams, logos, screenshots of text and simple illustrations all survive the palette drop almost untouched.
