DropGIF is a free online tool for creating animated GIFs from video files or a sequence of images. It operates entirely within the user’s browser, meaning no files are uploaded to any server and no account or sign-up is required. The primary function is to convert a video clip (in MP4, MOV, WebM, or GIF format) or up to one hundred photos into an animated GIF, with the option to trim, resize, and adjust export settings before downloading. Exported GIFs are generated without a watermark on the free tier, which supports clips up to twenty seconds in length and a maximum width of 480 pixels. The tool offers a range of additional editing capabilities beyond basic conversion. These include a GIF compressor, a resizer, the ability to add text, reverse the animation, change playback speed, and turn a screen recording or a WebM file into a GIF. Users can create transparent GIFs by keeping existing transparency from PNG or WebP source files, using an eyedropper to remove a specific color (such as a green screen), or employing an on-device AI model to cut out people from the background. A set of templates, such as a swinging heart locket or a waving flag, allows users to apply a prebuilt animation to a photo. The “Where it fits” feature checks the output GIF size against the upload limits of platforms like Discord, X, and Slack, and offers a one-click “Fit” option to reduce file size by adjusting width, frame rate, or color count. Typical use cases include creating shareable animations from personal videos, screen recordings, or photo bursts without relying on cloud processing. The workflow involves dragging a file into the browser window or pasting it from the clipboard, trimming the desired portion, selecting a width, and exporting the GIF. For photo sequences, users drop between two and one hundred images, each serving as a separate frame. Because all processing occurs locally on the device, the tool works offline once the page has loaded and can be installed as a progressive web app for use without an internet connection. DropGIF does not generate GIFs from text prompts or use AI for any purpose other than local background removal. The tool is accessible on any recent phone or computer via a modern web browser.
