One Powerful Platform for Images, Video & Audio
One platform to store, transform, and serve media files. Trusted by 1000s of developers to simplify for file storage, realtime media processing, and optimized content delivery.
// Upload files with a few lines of code:import { UploadManager } from "@bytescale/sdk";const file = event.target.files[0]; // <input type="file" onchange="..." />const uploadManager = new UploadManager({ apiKey: "API_KEY" });const { fileUrl } = await uploadManager.upload({ data: file })
// ...or use the Bytescale Upload Widget:import { UploadWidget } from "@bytescale/upload-widget";UploadWidget.open({ apiKey: "API_KEY" });
// ...or use the Bytescale REST API:curl "https://api.bytescale.com/v2/accounts/ACCOUNT_ID/uploads/form_data" \ -H "Authorization: Bearer API_KEY" \ -F file=@image.jpg # File must exist locally (include @).- Uploading Files

Adaptive Bitrate (ABR): stream in multiple bitrates and resolutions for difference devices.
HTTP Live Streaming (HLS): reduce bandwidth usage, playback latency, and buffering.
H.264, H.265, VP8 & VP9: optimized next-generation video codecs.
Audio processing APIs
Convert, optimize, and concatenate audio files with our real-time audio processing APIs.
Convert audio: from almost any input format.
Optimize audio: set sample rate, bitrate, etc.
Real-time transcoding: playback in seconds.

Use Bytescale as your CDN
Did you know: you can bring your existing storage to Bytescale, giving you realtime media processing APIs and an ultra-fast CDN, without needing to move your files.
Built-in storage: Works out of the box.
External storage: AWS S3, Google Storage, Cloudflare R2, and DigitalOcean Spaces.
Reverse proxy support: process images, videos, and audio hosted elsewhere via HTTP.
Public and private assets
Optionally protect your images, videos, and audio using JWT-based auth, to give your app control over file access permissions.
Public file access: serve public assets for your app or website.
Private file access: use JWTs to authorize uploads and downloads via your own API.
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.
Optimized content delivery
Optimize and serve images, videos, and audio at lightning-fast speeds
to reduce page load times and improve the UX of your web app.
Realtime Media Processing
External Storage Support
Permanent Caching
600+ Locations
Affordable for everyone
Bytescale outperforms bundled, home-grown, and dedicated image processing solutions in cost efficiency, making it the top choice 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 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.
Bytescale handled millions of new images per month for our viral marketing campaign. It's a powerful, scalable platform.
