Questions & Answers

As answered by people managing Viewer.Online and Comapi.

What makes your product unique?

Viewer.Online's answer

Most online file tools focus on a small number of popular formats or require users to install software, create an account, or wait for conversions to finish.

Viewer.Online is built around a different idea: open first, understand immediately.

Users can drop a file directly into the browser and instantly preview its contents without installing software or configuring anything. Viewer.Online is designed to support a very large number of file formats and uses smart content extraction to present files in a readable and useful way whenever possible.

The goal is simple: make opening files feel effortless.

Why should a person choose your product over its competitors?

Viewer.Online's answer

Viewer.Online is a good choice for people who value speed, simplicity, and convenience.

No installation required Works across desktop and mobile devices Supports a broad range of file formats Fast drag-and-drop workflow Useful for unknown or uncommon file extensions Reduces friction when quickly checking files

Viewer.Online was created to remove unnecessary steps and make file access faster, easier, and more accessible.

Which are the primary technologies used for building your product?
