The results heavily depend on the nature of the image. This option keeps the first frame in the background and makes unchanged parts of the following frames transparent. This will not do anything for most GIFs but can be useful in some special cases. This method will search for identical or very similar consecutive frames, remove them and merge their display duration. Useful for long gifs with a high frame rate.Īnother option is to remove only duplicate frames. The frame drop option can remove every second, third, or fourth frame to reduce frame rate and, therefore, file size. It makes multiple variations of your input image, and you can choose the one with the best size/quality ratio for your needs. This tool shrinks the GIF file size by reducing the number of colors in each frame.Įach GIF frame can use up to 256 unique colors, and by reducing this number, you can achieve a smaller file size. This is the default method and should work for any GIF. You can adjust the compression level with a simple slider to get the best result for your use case.
It can reduce the animated GIF file size by 30%-50% at the cost of some dithering/noise. You will get a versatile image with great quality, that you can send to anyone without taking too much time.GIF compressor optimizes GIFs using Gifsicle and Lossy GIF encoder, which implements lossy LZW compression. If you have a huge photo, we recommend resizing it to about 1900 by 1100 pixels, with JPG format and 90% quality.
So if you resize your image, decreasing its width and height to a half, your image would have about the same number of pixels as the screens that will display it, and you wouldn't be losing any quality or detail, even looking at your image in full screen mode.
Photos from modern cellphones and cameras usually have over 6 million pixels, while most cellphones, tablets, notebook or TV screens have only about 1.5 million pixels, which means you end up seeing a resized version of the image (you only use the full image if you print it). Reducing image size doesn't reduce image quality, although it may lose small details. Image quality will suffer as you increase compression and start losing more data.Īnother method is to resize your photo, decreasing the pixels it takes to store the image. One way is compressing the image, which reduces file size without having to resize it.
If you want to send this photo (or many photos) to a friend by e-mail, it will have to transfer 30 megabytes of data and it will take a while to upload it and a lot for the recipient to download it later. And having 10 million pixels means it takes 30 million bytes (or 30 megabytes) to store that photo (which is a lot of space!).
When a camera or cellphone says it takes 10 megapixels photos, it means that each photo has 10 million pixels (mega = million). When an image is large, it may have millions of pixels, and that means storing all information for an image like that in a computer or any device will take millions of bytes. To store each of these pixels, 3 bytes (24 ones or zeros) are generally used. Images are composed by several dots called pixels, and each of them has a color, represented as a combination of three basic colors (red, green and blue).
