Utilities that do the work and forget your files.

Axiom Opus Labs builds fast, privacy-first, intelligent utilities for document processing and digital media workflows. Two shipped products, one engineering standard: your files are processed, not collected.

  • Browser-native
  • No sign-up to start
  • Files deleted after processing

The standard across every product

  • No file retention
  • Sub-second common operations
  • AI where it earns its place
  • Works in the browser

Shipped products

Two products. One set of rules.

Each product owns its craft and its accent colour — and inherits the same privacy model, the same speed budget and the same interface grammar.

OpusPDF

Live

High-performance document processing. Merge, split, convert, OCR, compress, sign and secure — 25+ operations that run the moment you drop a file, with seven tools open to guests before any account exists.

  • Merge & split
  • OCR extract
  • Sign & secure
  • PDF → Word
  • PDF → Excel
  • PDF/A
  • Workflows

OpusImg

Live

A web-based image engine. Compress, resize, convert, crop and edit in the browser — then reach for background removal, upscaling and enhancement when the work needs a model behind it.

  • Compress
  • Resize & crop
  • AI enhance
  • WebP
  • AVIF
  • HEIC
  • Batch queue
  • Background remove

How we build

Three constraints we design against.

Privacy is the default path

Basic operations never leave the device. What does go to a server is processed and dropped — file contents, auth headers and tokens never reach a log or an error report.

Speed is a budget, not a hope

Common operations run in the browser. Heavy work goes to services sized for it, so a compress or a convert finishes while you are still looking at the page.

Intelligence where it pays

Models handle the jobs deterministic code does badly — OCR, upscaling, background removal, summarisation. Everywhere else, plain fast code wins and we use it.

Engineering

A small stack, run deliberately.

One lab, two products, a shared platform. Every service is placed where its data already lives, and every recurring cost is decided before it is created rather than explained after it appears on an invoice.

In the lab

What the Opus suite is growing into.

One product in the lab right now. Dates are set when the work is honest about being ready, not before.

OpusStride

Early limited access beta

An AI resume and cover-letter workspace with an ATS checker — the same privacy model applied to the documents people care most about. Open to a small group of testers while the work proves itself.

Request access

Start with a file. No account, no upload limit theatre.
