Why do my gifs have a white outline?
This happens because the edges of the image need to gently transition into the background colour. In this example Photoshop has assumed that the background will be white, so it has faded the edges towards white.
How do I make a GIF not transparent?
Sure! Either delete the background from each frame manually before making a GIF (save the image as GIF or PNG to preserve transparency, JPG will not work!), or, if your GIF has a solid color background, use effects tool and select “Replace color with transparency” option.
How do I get rid of the white border around a GIF?
Choose a Matte color They support 1bit transparency. What this means is you can choose 1 color to replace the default halo white. This is how you do it in Fireworks.

What is transparency dither?
Pattern Transparency Dither applies a halftone-like square pattern to partially transparent pixels. Noise Transparency Dither applies a random pattern similar to the Diffusion algorithm, but without diffusing the pattern across adjacent pixels. No seams appear with the Noise algorithm.
Can a GIF file be made semi transparent?
GIF format is the main file format for making animations for the present and success at making transparent gif and animated images that look good depends upon knowing about semi-transparent pixels, antialiasing, and semi-flattening. GIF files can not handle semi-transparency therefore those pixels need to be completely filled with color.
What does it mean to semi flatten a GIF?
When you create text or draw you get something called antialiasing. That is the addition of semitransparent pixels around the image. It gives a smooth look to the image. If you don’t semi-flatten it, .gif image format deletes those antialiased pixels and you get a rough, not so nice finish.
Is the transparency of a GIF file anti aliased?
Also note that GIF files only support 1-bit transparency, which means that the edges of the transparent regions will not be anti-aliased.
Is there a way to shrink a GIF file?
The -O2option is not strictly necessary, but it’s likely to shrink the file size of the resulting animation by optimizing the frames to avoid needlessly re-drawing static parts of the animation.)
