Pixel Agent

Pixel Agent

Pixel Agent converts image bytes to PNG, JPEG, WebP, or AVIF. It has a browser UI and a headless HTTP API. AI agents should use the API directly; browser automation is not required.

Convert an image

Send a POST request to /v1/convert with raw image bytes in the request body.

curl --fail --silent --show-error \
  --request POST "https://YOUR-WORKER/v1/convert?format=webp&quality=85" \
  --header "Content-Type: image/png" \
  --header "X-Filename: input.png" \
  --data-binary "@input.png" \
  --output "input.webp"

Inputs and outputs

• Inputs: PNG, JPEG, GIF, WebP, SVG, AVIF, and HEIC
• Outputs: PNG, JPEG, WebP, and AVIF
• Maximum API input: 20 MB
• quality: optional integer from 1 to 100 for JPEG, WebP, and AVIF

The response body is the converted image, with a safe filename in Content-Disposition. The API does not persist image bytes and sends Cache-Control: no-store.
