MB GIF Resizer

MB GIF Resizer provides a precise, automated way to resize animated GIFs for web and app usage. It targets designers, marketers, and developers who need consistent output sizes without manual frame-by-frame editing. The tool accepts a GIF and target dimensions, offering aspect-ratio preservation and multiple resizing modes. Conceptually, it operates by scaling each frame with a chosen resampling method, then reassembling the frames with preserved timing to retain playback fidelity. Users can opt for fit, crop, or pad modes and, when padding is selected, specify a background color for a clean border. It supports color quantization and dithering as optional enhancements to balance quality and file size. The primary value lies in delivering project-wide consistency, reducing manual editing time, and ensuring that animated assets render correctly across platforms. Use cases include social media campaigns requiring uniform GIF sizes, app previews embedded in websites, and product demos that demand predictable dimensions. Distinct advantages include per-frame consistency, preservation of frame order and delays, and straightforward controls tailored for animated assets rather than static images. Core capabilities encompass input validation, dimension handling, and clear output metadata such as width, height, frame_count, and total_duration. The tool emphasizes robust error handling for invalid inputs and large files, and it adheres to GIF specifications to maximize compatibility across browsers and devices.
