Compress GIF images with an API

Compress a GIF directly in the live demo below, or use the same Assembly Instructions to optimize GIF uploads automatically. 🤖/image/optimize keeps the GIF format and animation while reducing avoidable file overhead.

This example favors compression ratio and removes metadata. Removing metadata can reduce the output further, but it may also remove copyright or attribution information, so preserve it when your workflow requires that data. The amount saved depends on the source palette, frame count, existing compression, and metadata.

GIF is widely supported but limited to a 256-color palette. For larger animations, converting to WebP or video may produce a substantially smaller result. Use GIF optimization when compatibility or an existing GIF workflow matters, and connect the final Step to your preferred storage provider in production.

Step 1:

Handle uploads

We can handle uploads of your users directly.Learn more

":original": {
  "robot": "/upload/handle"
}

/upload/handle

This bot receives uploads that your users throw at you from browser or apps, or that you throw at us programmatically

Step 2:

Optimize images without quality loss

We can resize, crop, and (auto-)rotate images, or apply watermarks and other effects, and much more.Learn more

Step 3:

Export files to Amazon S3

We export to the storage platform of your choice.Learn more

Loading Uppy demo…

This live demo is powered by Uppy, our open source file uploader that you can also use without Transloadit, and tus, our open protocol for resumable file uploads that is making uploading more reliable across the world.

Build this in your own language

<!-- This pulls Uppy from our CDN -->
<!-- For smaller self-hosted bundles, install Uppy and plugins manually: -->
<!-- npm i --save @uppy/core @uppy/dashboard @uppy/remote-sources @uppy/transloadit ... -->
