GIF Upscaler

No. GIF decoding, enhancement and encoding run on your device. Only the model files need to be downloaded.

All frames, their original delays, the loop count and transparent areas are preserved. Width and height both double.

Results depend on the source. Anime4K is especially suited to animation and line art. Very blurry footage, small text and photographic details may not improve. Preview the result before saving.

Up to 128 MB, 2,000 frames, 2,048 pixels per side and 1,048,576 pixels per frame. Total output is limited to 1,000,000,000 pixels across all frames and 512 MB. Device memory may require a smaller GIF or Fast mode. Larger animations require available local browser storage. Processing limits also depend on your device.

Fast and Balanced require WebGL 2 with floating-point rendering. High quality requires WebGPU. Availability depends on your browser and graphics hardware. Enable hardware acceleration or try another browser if no level is available.

Usually. Doubling width and height creates four times as many pixels. This tool keeps the enlarged dimensions; use the GIF compressor afterward if you need a smaller file.
