GIF Target Size Compressor for Discord & Slack

Compress your animated GIFs, APNG, WebP, AVIF, or JXL images to fit exact file size limits for Discord, Slack, email attachments, web upload limits, or forums. Note: This tool accepts various animated input image formats (APNG, WebP, AVIF, JXL), but the output file will always be converted and saved as an animated GIF. For manual compression parameter tuning, try our general GIF optimizer tool.

Platform Preset Limits:

  • Slack Custom Emojis: Must be under 128 KB.
  • Discord Custom Emojis & Stickers: Must be under 256 KB.
  • Discord & Slack Chat Uploads: Standard limit 10 MB (or 8 MB depending on server settings).
  • Discord Nitro Uploads: Up to 50 MB.

Intelligent Multi-Pass & Progressive Frame Dropping

Our smart algorithm automatically calculates the optimal combination of lossy compression, dimension downscaling, progressive frame dropping, and color limiting to ensure your GIF fits within your chosen file size limit while maintaining the highest possible visual quality.

You can also use our crop tool or GIF cutter to trim unwanted borders or frames before compressing.
