View Any File Right in Your Browser
— No Download Required
Not sure a file is the right one before you save it to your device? Transferly's online file viewer opens images, videos, PDFs, and documents straight from the share page, so you can check first and download only if you need to.
Quick Answer
1. Why Preview a File Before Downloading?
Downloading a file you're not sure about wastes storage, time, and — on a mobile connection — data. A quick preview answers the obvious question first: is this the right file, is it the right version, does it look correct?
Transferly's file viewer opens directly on the share page, so recipients can check a file with one click and only download the ones they actually need.
2. What the File Viewer Supports
Images
JPG, PNG, GIF, WEBP, SVG, and more render full-size with thumbnail previews in the gallery.
Video
MP4, MOV, WEBM, MKV and other common formats stream and play directly, no download needed.
Documents & PDFs
PDFs and common document types open inline for a quick read-through.
Multi-file galleries
Transfers with several files show a gallery view — click any thumbnail to open the full preview.
Password-protected transfers
Preview works after password verification, so protected files stay protected.
3. How to Preview a Shared File
Open a Transferly share link. If it's password protected, verify the password first.
Files are laid out in a gallery — click any thumbnail to open the full preview viewer.
Browse between files with the built-in navigation, and download only the ones you need.
Free, no account required
