Robin shrinks text, audio, and images through one API. Smaller files mean cheaper storage, faster transfers, and fewer tokens burned on every model call.

Results in one call.

Infrastructure for compression, turning heavy files into light ones without you thinking about codecs, encoders, or queues.

  1. 1

    Upload

    Presigned PUTs straight from the browser or your backend. Drop the file, get a handle back.

  2. 2

    Pick a preset

    Opus for speech, WebP or AVIF for images, token compression for prompts. Sane defaults, tunable knobs.

  3. 3

    Jobs and webhooks

    Small files return inline. Big ones queue, and you poll, long-poll, or get a webhook when done.

  4. 4

    Ship it lighter

    Every job reports input, output, and savings. Download from a signed URL and move on.

Built for every product.

Compression for teams shipping AI features, media platforms, and fast pages.

AI products

Trim prompts and context before they hit the model. The same answers cost fewer tokens, on every call.

Media platforms

Podcasts, voice notes, and user uploads stored at a fraction of the size, with the fidelity that matters kept intact.

Web performance

WebP and AVIF assets generated on demand. Lighter pages, faster loads, smaller bandwidth bills.

Secure by design.

Your files pass through, get lighter, and leave. Nothing sits in a public bucket, nothing is delivered unsigned.

Hashed API keys

Keys are stored as sha256 hashes. The raw key is shown once, then never again.

Signed webhooks

Every delivery is HMAC-signed so you can verify it came from us.

Signed downloads

Results live behind expiring signed URLs, never public buckets.

Two ways in. The same small files out.

Dashboard

Upload, pick a preset, download. Track credits, savings, and job history from one place.

API

One POST, one lighter file.

Bearer keys, idempotency, long-polling, webhooks. Built to sit quietly inside your pipeline.
