About Giflumo
A small toolkit for moving ideas
Giflumo brings four everyday GIF tasks together: compression, video conversion, image sequences and resizing. Choose a file, adjust settings, preview and download, without an account.
Scope and compatibility
Tools process selected files in your browser. There is no URL downloader, cloud media library or full timeline editor. MP4 decoding depends on your browser and the video codec. Format and processing limits appear on each tool.
When something goes wrong
Keep the original file. Note the tool, browser version, file format and size, settings and error message. Try refreshing, shortening a clip or reducing output dimensions. Avoid sharing sensitive source material publicly.
