GIFSpeed

GIFSpeed is an all-in-one GIF toolbox that runs entirely in the browser. It officially claims to offer 32 free GIF-related tools, with all processing done locally within the browser, without needing to upload files to any server.

Purpose and Positioning GIFSpeed is aimed at creators and developers, for handling various common needs when working with GIF animations: changing playback speed, compressing size, cropping the frame, resizing, format conversion, and generating GIFs from images or videos, etc. The official emphasis is that all tools run directly in the browser using WebAssembly, with no server queue, and most file processing times are within 3 seconds.

Main Capabilities According to official information, the tools provided by GIFSpeed include:

• Speed control: speed up GIFs to 2x, 3x, or 4x, or create slow-motion animations.
• Compression: reduce GIF file size through color optimization and lossy compression. It is officially claimed that file size can be reduced without loss of quality, suitable for meeting Discord's 256KB emoji limit or shrinking email attachments.
• Editing: reverse playback, rotate or flip, crop by time range, split into two clips by time, merge multiple GIF clips, crop the frame, resize while preserving animation.
• Frame processing: extract GIF frames as separate PNGs, export GIF as a single PNG sprite sheet, convert sprite sheets back to GIF, and slice sprite sheets into separate frame images.
• Loop control: set the GIF loop count to infinite, once, or a custom number of times.
• Text and creativity: add subtitles, meme text, or labels to GIFs; Typing Text GIF can generate a typewriter animation GIF from text; My Beloved Edit can add post-processing effects to GIFs.
• Creation: create animated GIFs or APNGs from JPG, PNG, or WebP images.
• Format conversion: convert between GIF and WebP, GIF and APNG, APNG and GIF; WebP to PNG; WebP to GIF; GIF to MP4; MP4 to GIF; MP4 to APNG; video to GIF; video to APNG; WebP to PNG; WebP to GIF, etc.
