Three tools in one
Images to GIF joins several pictures into one animation. They play in the order of the list, each for 0.2, 0.5, 1 or 2 seconds, and every image is fitted to the size of the first one with a white background where the shapes differ. It's perfect for a product shown from different angles, a before and after, a simple step-by-step or a slideshow of photos for a chat.
Animation to GIF takes an animated WEBP or GIF and saves it as a GIF, for example to make a WEBP sticker or meme work in apps that don't play WEBP, or to shrink a heavy GIF to 320 or 480 px. Extract frames takes an animation apart and gives you each frame as a PNG in a ZIP, useful for picking a still for a thumbnail or editing frames one by one.
Size, speed and looping
The size option sets the longest side to 320, 480 or 720 pixels, or keeps the original. Smaller GIFs load faster and are easier to send, which matters in emails, forums, support tickets and chat apps. The repeat option makes the animation loop forever or play once. Up to 300 frames are handled per animation.
For images to GIF, put the largest or most important image first, since it sets the canvas size for the rest.
Honest limits of the GIF format
GIF is old and universal, which is why it plays nearly everywhere, but it can only show 256 colors per frame. Flat graphics, screenshots, icons and cartoons look great; photos with smooth gradients, skies or skin tones can show banding or a grainy dither. That's the format, not the tool.
The animation to GIF and extract frames modes need a browser that can read animations frame by frame: Chrome, Edge or Firefox. Safari can't do it yet, and the page tells you if that's the case. Images to GIF works with still pictures.
Ideas for each mode
Images to GIF: a product carousel for an online store listing, a quick tutorial from four or five screenshots, a before and after of a renovation, a countdown or an announcement with a few slides, or a short loop from a burst of phone photos.
Animation to GIF: an animated WEBP saved from a website that your messaging app, email client or presentation software won't play; a reaction GIF that's too heavy to post and needs to shrink to 320 px; a sticker you want to share in a place that only takes GIF.
Extract frames: the best still from a short animation for a thumbnail or a cover, single frames to retouch in a photo editor before rebuilding the GIF, or sprites from a pixel-art animation.
Private and free
The GIF is built inside your browser. Your images and animations are never uploaded or stored, there's no account, no watermark and no limit on how many GIFs you make.
