Read photos and low-quality scans

Our API has powerful built-in image pre-processing filters that can correct rotated and skewed images, and automatically remove dirt, spots, scratches, glare, unwanted gradients, and other image defects. In combination with support for all image formats, it allows for reliable recognition of even smartphone photos. Most of the pre-processing and image correction is done automatically, so you will only have to intervene in difficult cases.

Recognize and convert

The API can read literally any image you can get from a scanner, camera or smartphone: PDF documents, JPEG, PNG, TIFF, GIF, and BMP images. Multi-page PDF documents and TIFF files are fully supported.

Recognition results are returned in the most popular document and data exchange formats: plain text, PDF, Microsoft Excel, CSV, and hOCR.

Minimal System Requirements

Aspose.OCR Cloud is an on-demand optical character recognition service. As such, it has no special hardware or operating system requirements - you can use it even on entry-level systems and mobile devices without loss of accuracy and performance.

We use highly reliable and high performance GPU-based Amazon servers to host our OCR engine, ensuring the fastest possible speed regardless of the number of requests.

Spell Check

While the OCR produces reliable results, dust and print defects might cause some symbols to be recognized incorrectly. Cloud OCR API has a built-in spell checker that automatically replaces misspelled words and frees you from having to manually correct the recognition results.

Create searchable PDFs

Convert a scanned PDF file to a searchable PDF document, which can be easily navigated and indexed. Text in searchable PDF documents can be selected, copied, and marked up.

Recognize images from the Internet

There is no need to upload images and PDF documents to the cloud storage for recognition. Just send the image web link to Cloud OCR and get the text.
