# Preview and share files

> Use inline preview, file details, presigned links, and share history in BucketMate Web

Canonical: https://docs.bucketmate.app/web/features/preview-share-and-edit-files

BucketMate Web helps you inspect files before downloading them and share objects without leaving the browser.

## Preview files

BucketMate Web supports inline preview for common browser-readable file types:

- Images
- Text files
- PDFs and browser-supported documents

Select a supported file and use the preview action. You can toggle the preview panel with the toolbar or shortcut.

## View file details

Use **View detail** to inspect object metadata without leaving the file list.

Details can include:

- Full object key
- File name
- Size
- Type
- Modified date
- Storage class
- Object URL
- Folder metrics for folders

## Create share links

BucketMate Web can create presigned URLs for objects.

1. Select a file.
2. Choose **Share** or **Create share link**.
3. Pick a preset duration or enter a custom duration.
4. Copy the generated URL.

Most S3 providers limit presigned URLs to 7 days. BucketMate Web caps the link duration when needed.

## Share-link history

BucketMate Web stores created share links in browser-local history so you can copy or open them later.

History entries can include:

- URL
- File name
- Bucket
- Object key
- Connection
- Creation time
- Expiration time
- Duration

Use **Settings > Shared Links** to search history, copy a previous URL, open it, delete one entry, or clear the history.

## Revoking share links

Removing an item from share-link history does not revoke the link. A presigned URL remains valid until it expires.

To invalidate a link before expiration, rename the object, delete the object, or rotate the credentials used to create the link.

## Copy direct URLs

Besides presigned links, BucketMate Web can copy direct object URLs. Direct URLs work only when the object and bucket are publicly reachable through that URL.
