Delays – all frames/selected frames: Under “Delays” you can set the time interval between the individual frames of the animation.You can also activate or deactivate the optimization of the color palette and color types using the tool. In the compression settings, you can select one of these algorithms. Compression settings: With zlib, 7zip, and Zopfli, APNG Assembler provides three different algorithms for compressing the animation.

You can also select “Skip the first frame” option if you want the first frame in the animation to be skipped. To do this, just uncheck “Play indefinitely” and enter the appropriate number.

Playback settings: In the playback options, you can set how often the animation should be repeated (without limitation by default).

Once you have added all the PNG images you want to include in the animation, you can specify the setup of this animation using the options below: GIF animations only provide support for simple transparency, which can create unattractive edges around the graphic (where it meets the background). Since APNG tends to have a smaller file size and also has a better compression behavior than GIF, the quality advantage still holds.Ī further advantage: Animated PNG supports not only complete, but also partial (graded) transparency, which makes a natural integration of the animations into the existing web layout possible. Of course, it is important to keep in mind that a higher quality of the animated images always leads to a growing file size. The GIF format with its 8-bit support is limited to just 256 colors. The fact that APNG is a serious alternative to the established GIF is illustrated by a look at the properties of the Mozilla format: APNG supports a color depth of up to 24 bits and thus over 16 million colors. The respective number is also automatically assigned to the preceding fcTL block, so that the different frames can be brought back into the correct sequence at any time.

Frame data chunk (fdAT): Frame data chunks are structurally equivalent to the standard PNG image data blocks (IDAT), but are additionally marked with a sequence number.

It contains information, the most important of which is the display time of the frame.

Frame control chunk (fcTL): The frame control chunk precedes each frame contained in the APNG animation.

It shows the number of frames that make up the animation and also describes how often the animation should be played before it stops.

Animation control chunk (acTL): This block informs the parser that the PNG is animated.

However, the Animated Portable Network Graphics format includes three additional types of information blocks (chunks) that describe the animation and provide additional frame data. An application program that supports PNG (but not APNG) is still able to play an APNG file, but in this case, just a single image can be seen, not the complete animation.įrom a technical point of view, the APNG data stream largely corresponds to the standard PNG data stream whose structure can be found in the official image format specifications. If you select this option and try removing the white color, then only the area around the donut will disappear but the inside of the donut will remain opaque.Although APNG does not count as an official PNG extension, it is backward compatible to the basic format. For example, if you have a PNG of a donut on white background, then the white color will be both inside and outside of the donut.

Additionally, we have added an option "Match Outer Pixels Only", which lets you remove only those areas that are in contact with the outer edges of the image.

This way, you don't have to know the name or code of the transparent color and you can make the PNG transparent by simply clicking on the color in the PNG. For example, if you click a green pixel, then all greenish pixels will be made transparent. Also, you can interactively click on the input PNG to instantly remove any color and its tones. By increasing the smoothness radius, you can remove more pixels from the edges and make PNG clearer. This option makes the pixels on the border between transparency and opacity semi-transparent. If you remove the color and the edges of the image still have a pixel or two of the old color, you can refine the edges and smooth them by enabling the "Smooth Edges" checkbox. For example, if the color that you're removing is red, then it will also remove cherry-red, rose-red, wine-red, and similar shades of red. By default, 30% similar color tones are matched but you can change it as you see fit. To match similar color tones, enter the similarity percentage in the settings.

This online browser program replaces any solid color and its close color tones in a Portable Network Graphics (PNG) photo or picture with transparent pixels.
