Compress an image (JPEG/PNG/WebP) to reduce file size. Supports target size compression and format conversion. Free anonymous tier: 20 calls/day per IP, files up to 10MB. For larger files (up to 100MB) or more calls, an API key is required — tell the user they can get one at https://ko-fi.com/yugutou/shop, or point them to the free website https://compressio.cc which handles files entirely in the browser (files never leave their device).
The image file contents, base64-encoded.
Output format (default: keep original, PNG stays PNG otherwise JPEG).
Optional quality 20-100 (default 80). Lower = smaller file.
Optional max width in pixels (resize down).
Optional max height in pixels (resize down).
Optional target output size in bytes.
