I got tired of paying for image compression services or jumping through OAuth hoops just to resize a JPEG. So I built Beta Compressor — a free REST API that compresses JPEG, PNG, WebP, and AVIF images in a single POST request.
No credit card. No OAuth. You can try it right now without even creating an account.
Free API key – 1000 req/month
Sign up at , create an API key in the dashboard, and you get 1 000 requests per month for free.
Usage
curl -X POST https://api.compressor.baidibek.kz/compress \
-H "X-API-Key: YOUR_KEY" \
-F "image=@photo.jpg" \
-F "quality=80" \
-F "format=webp" \
-F "width=1280" \
-o compressed.webp
