Image Processing Image Optimization File Compression
Image Compression
Compress and resize JPEG, PNG, or WebP images
What can this API do?
Uploads and public image URLs
Optimize files supplied by users or images already available through a public HTTP(S) URL.
JPEG, PNG, and WebP
Accept the three common web image formats and choose the output format your workflow needs.
Aspect-ratio-preserving resize
Fit images within target dimensions without distortion or unnecessary upscaling.
Quality control
Balance file size and visual quality for JPEG and WebP while keeping PNG output lossless.
Direct optimized image bytes
Receive the processed image with the correct media type and a usable download filename.
Faster media delivery
Reduce image payloads for websites, mobile apps, storage, email, archives, and publishing pipelines.
Plan and usage
What does the 5 requests per second limit mean?
It is a request-rate limit, not a concurrency allowance. Keep your request rate at or below 5 per second. If the service returns a rate-limit response, reduce the frequency and retry with backoff.
Is total paid usage limited?
There is no total request cap during an active paid subscription and no usage-based overage charge.
How does the free trial work?
Each account can receive a limited trial key. Requests are shared across APIs in the same category. Check Trial Keys for the exact allowance and remaining requests.
How do renewal and cancellation work?
The plan renews annually until canceled. Manage or cancel the renewal from Dashboard → Orders & Billing. Access continues through the paid period after cancellation. See the Terms of Service for the current refund policy. If the billing portal is unavailable, contact support.
