Transparent gif filler

World's simplest gif tool

This online utility lets you create opaque GIFs. It finds all transparent pixels in a GIF and fills them with a solid color. The fill color can be specified in the options and the GIF can be previewed in the browser and downloaded. Created by GIF experts from team Browserling.

Transparent gif filler tool What is a transparent gif filler?
This is a browser-based program that converts transparent GIF regions to non-transparent GIF regions. It replaces the color indexes that are used for the transparency with a different color index that you can enter in the options. You can fill all GIF frames with the same color if you enter the star symbol "*" in the option "Frames to Fill". You can also fill only certain frames or a range of frames if you enter frame numbers, such as "2, 5, 10" or a range of frames "4-50". This way you can add a solid background to GIFs and fill transparent gaps with any color in any frame you need. Each opaque GIF can be downloaded by clicking the save buttons below the GIF preview area. The opaque color can be set in the options by its name (for example, "green"), by the hex code (for example, "#00ff00"), by the RGB code (for example "rgb(0, 255, 0)"), or by choosing the color from the color palette. You can immediately see the fill results on right in the browser (or below on a mobile phone) and animate the entire GIF, or stop at a specific frame to examine the fill quality in more detail.

Opaque Netflix Logo
This example converts a transparent Netflix logo GIF animation into an opaque animation. It uses the black color as the fill color and replaces every transparent pixel in every frame with this color. The input and output GIFs have 91 frames. (Source: Giphy, created by: Netflix.)

DNA Double Helix
In this example, we add a solid background to an animated GIF of the DNA double helix. We fill GIF's transparency with the keppel-green color that's entered in the color-to-fill option as a hex code "#30ad9a". The nontransparent GIF has all its 40 frames changed to this color.

Add GIF Background
In this example, we load a GIF with 15 frames featuring NFL rookie Jerry Jeudy, who was drafted in 2020 by the Denver Broncos. We use the frames-to-fill option to add background color only to the second half of the GIF. We specify the range of 8-15 in this option, which means the frames 1-7 will remain transparent. We set the background color using the color palette and use the purple color in RGB format "rgb(152, 68, 238)". (Source: Giphy, created by: NFL.)
