Remarkable performance

Serve images, videos and audio to millions in seconds, with a media-optimized CDN and media processing APIs.

Up to 90% smaller images, videos & audio

~10ms latency: edge-cache hits

~200ms latency: perma-cache hits*

* Bytescale uses a permanent cache to return processed images, videos and audio near-instantly on all edge-cache misses, forever.

Content Delivery Network (CDN)

Cheaper image optimization

Bytescale is cheaper than most bundled solutions, home-grown solutions, and dedicated image optimization solutions on running costs.

Bytescale is the best solution for large web apps.

Low pricing: $0.25 per 1000 source images*
(Industry average: $5 - $15 per 1000 source images.)

No monthly re-billing: no charge for image optimizations you've already performed.
(Many vendors charge for the number of optimized images requested each month, even if you've optimized them before.)

Adjustable costs: configure processing time vs. bandwidth to suit your app's traffic profile.

Permanent image caching

* Bytescale charges based on processing time, which you can control through image compression, image quality, output format, and output dimensions. $0.25 per 1000 images is based on 600ms of processing time per image, which is the approximate time it takes to process a 4000×3000 JPEG into a thumbnail.
