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 one 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 compressor.baidibek.kz, create an API key in the dashboard, and you get 1000 requests/month for free.
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
