DocEnhance

We’re serious about the “transformation” part of digital transformation. Use Onymos DocEnhance to dramatically improve the quality of scanned and photographed documents.

Enhance image quality for OCR or human verification

Onymos clients use DocEnhance in apps that process documents at mobile vaccination centers, stores, warehouses — and everywhere their customers are.

Get DocEnhance in your app

Accepts multiple file types

Whether it’s a PNG, JPEG, TIFF, PDF, or even a multi-page document, DocEnhance can accept and transform it.

Over a dozen settings

Just choose from preset enhancements optimized for different image types (like ones produced by low-resolution scanners) or leverage fine-grained control over image color, height, and quality with optional parameters.

Image enhancement made easy

Automatically remove watermarks on an image, crop its background, adjust its skew, boost its dynamic range, and perform even more enhancements — with just one endpoint.

Even better with DocID and DocKnow

Onymos Features are always better together. Make sure you’re enhancing the right images with DocID. If you’re using DocKnow, DocEnhance makes handwritten text appear clearer and bolder for even more accurate OCR.

Everything you need for DocEnhance

The simplest, fastest way to dramatically improve the quality of images in your app.

Easy to use

Submit images to be enhanced, retrieve them, and view usage metrics — just three endpoints with intuitive parameters.

RESTful API

Unlike other Onymos Features delivered as code libraries, DocEnhance’s functionality is accessed through a RESTful API.

No looking back

Onymos supports the Feature at every stage. Updates are as simple as rebuilding with our newest object release.
