Preview

For many file types, you can view the contents right in onmeil.eu, without downloading and opening them locally.

How to preview a file

1. Go to Files and find the file
2. Click it in the list — or choose View from the More actions menu

The preview opens as an overlay on top of the Files view. You can close it with × or the Esc key.

Which file types are supported?

We can preview most common file types:

• Images (JPG, PNG, GIF, WebP, SVG, HEIC) — shown at full size
• PDF — page through with the arrow keys or scroll
• Video (MP4, MOV, WebM) — built-in player with play/pause/sound
• Audio (MP3, M4A, WAV) — built-in audio player
• Office documents (.docx, .xlsx, .pptx) — open in a full editor
• Text files (.txt, .md) — shown as plain text

When preview isn't available

Some file types we can't preview in the browser — for example obscure formats or very large files. In that case you'll see the message:

"Preview isn't available for this file type. Download it to open locally."

If so:

1. Click Download
2. Open it locally in the program that handles that file type

Navigate between files

In the preview, you can switch files without closing the modal:

• Use the ← and → arrow keys to jump to the previous or next file in the list
• Or scroll with a trackpad / mouse wheel (mobile and touchpad)

Download or share from the preview

At the top of the preview modal, you have buttons for:

• Download — saves a copy to your disk
• Share — opens the sharing modal (see Sharing and permissions)
• Star — mark the file as a favorite

Tips

• Press Esc to quickly close the preview and return to the file list
• For images: click the image itself to zoom (use scroll to adjust)
• For PDFs: use the search function in the PDF viewer (Ctrl+F or ⌘F) to find text
