🎯 GIF 最適化ツール

When should you optimize an existing GIF?

GIF optimization is useful when you already have an animation but the file is too large, loads slowly or exceeds upload limits. Typical examples include compressing GIFs before reposting on social media, preparing GIFs under 8 MB for Discord/Telegram, or shrinking decorative GIFs used on websites.

By tuning quality, frame skipping and resize percentage, you can find a good balance between visual clarity and file size so the main motion stays smooth while less important detail is reduced.

Recommended combinations of quality, frame skip and resize

A practical approach is to first lower quality modestly and then resize the GIF to about 80–60% of its original dimensions, which already cuts file size significantly. For long GIFs, enabling frame skipping (for example, keeping every 2nd or 3rd frame) often reduces size a lot while keeping motion acceptable.

For small reaction GIFs or previews you can be more aggressive, while product demos or tutorial GIFs should keep higher quality and more frames. In those cases, rely more on reducing resolution rather than extreme quality degradation to stay within file-size limits.
