How to Convert JPEG to GIF

  1. 1

    Upload the JPG

    A photo, logo or scan saved as .jpg or .jpeg, up to 50 MB (up to 10 files at once).

  2. 2

    Reduced to 256 colors

    The picture gets a palette of its most important colors, and every pixel is matched to one of them.

  3. 3

    Download the GIF

    Upload it where GIF is required. One JPG makes one still GIF.

When a GIF is the only option

Some forum boards, older content systems, email tools and embedded devices accept GIF but not JPG. Converting is the quick way to get a picture into them. GIF suits logos, icons and simple drawings with few colors; for photos it is a compromise, as the rest of this page shows.

What 256 colors do to a photo

A JPG photo can contain millions of different colors; a GIF holds at most 256. The converter picks the 256 that best cover the picture and moves every pixel to the nearest one, without dithering. In our photo test the average pixel moved by about 3 of 255 levels, but some moved by up to 64, which shows as flat patches and bands in skies, skin and shadows.

File sizes we measured

GIF almost always comes out larger than the JPG. Even the flat logo grew, because JPG compression had left faint noise around its edges that the GIF has to store as extra colors.

What the GIF does not get

  • Animation: one JPG becomes one still frame.
  • Transparency: a JPG has none, so the background stays as it is.
  • DPI and color profile: GIF files do not store them.
  • Camera details and location (EXIF) are not copied; a phone photo is turned upright first.
