Convert AVIF to PNG with an API

Convert AVIF to PNG directly in the live demo below, or use the same Assembly Instructions in your application. 🤖/image/resize handles the conversion as files are uploaded and can process an existing media library through an import Robot.

PNG preserves transparency and uses lossless compression, making it useful for editing, graphics, and software that cannot read AVIF. A PNG result is usually much larger than the AVIF source because AVIF uses newer, more efficient compression.

Keep the AVIF original when storage and delivery efficiency matter. Use PNG when lossless pixels, alpha transparency, or compatibility with an editing workflow matters more than file size. For production workflows, connect the conversion Step to your preferred storage Robot. See all supported image formats and image-processing options.

Step 1:

Handle uploads

We can handle uploads of your users directly.Learn more

cat.avif

Image – 370 KB

":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:

Convert, resize, or watermark images

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

"converted": {
  "use": ":original",
  "robot": "/image/resize",
  "result": true,
  "format": "png"
}

/image/resize

This bot resizes, crops, changes colorization, rotation, and applies text and watermarks to images

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

<!-- For smaller self-hosted bundles, install Uppy and plugins manually: -->
