## Edit And Preview Documents Right In The Browser

**Open a Word, Excel, or PowerPoint file in Files.com and edit it in the browser. Work on one live file together with your team, and even with partners outside your company.** No Office 365 license to edit, no downloading and re-uploading, no Final-v3-versus-v4 confusion. And every preview, edit, and save is on the record.

## The Download-Edit-Reupload Habit Is The Problem

Here’s how most teams edit a shared document: download it, open it locally, change it, upload it back, and email everyone the new version. Then someone edits the old one. Now there are two files, two sets of changes, and no clean answer for which is right. And a copy of the document is sitting on someone’s laptop where nobody can see it.

The Files.com Editor cuts the whole loop. The file stays where it lives, and people edit it in the browser, together, in real time. One live file, one version, every edit attributed to whoever made it. Nothing leaves the platform to be edited, so **the most common way data walks out the door never starts.**

## Co-Editing Built Into The Platform

Real-time editing for Office files, for your own team and for the partners you work with.

### Preview Without Downloading

View PDFs, images, videos, and Office documents right in the browser. No download, no "open in another app." Just click the file and read it.

### Preview-Only For Sensitive Files

Let someone read a document without being able to edit or download it. The right setting for a contract or a record you want seen but not copied.

### Watermark Each View

Stamp the viewer’s identity across every preview, so a leaked screenshot points back to who took it. It’s a deterrent and a way to trace a leak. It won’t stop a determined person from taking a screenshot.

### No Two-People-At-Once Collisions

File locking coordinates across the browser editor and the desktop editing path, so two people can’t quietly overwrite each other’s work on the same file.

## Compliance-Grade Collaboration

**Editing in the browser does not mean editing outside your controls.** Your own people sign in through your [identity and permission setup](https://www.files.com/features/groups-and-multi-level-user-administration). Outside co-authors arrive through a share link. Every session runs under the same encryption, retention, and access rules as the rest of your data, with SOC 2 Type II, HIPAA, and GDPR posture underneath.

Pair that with the unified [audit log](https://www.files.com/features/audit-log), and the editing that used to leave copies on laptops and files in inboxes becomes one tracked activity you can show an auditor.
