# Preview, share, and download

> Preview files with Quick Look, share them, save them to Photos or Files, and copy presigned links in BucketMate for iOS

Canonical: https://docs.bucketmate.app/ios/features/preview-share-and-download

BucketMate uses iOS Quick Look, the system share sheet, Photos, and the Files app so stored objects work like local files on your iPhone.

## Preview a file

1. Tap a file, or touch and hold it and choose **Preview**.
2. BucketMate downloads the file and opens it in Quick Look.
3. Tap **Done** to close the preview.

Quick Look handles images, videos, PDFs, text, and other formats iOS can display.

## Share a file

1. Touch and hold a file.
2. Choose **Share**.
3. Pick an app or action from the system share sheet.

BucketMate downloads the file first, then hands it to the share sheet. To share many files at once, use multi-select (Pro). See [Browse and manage files](/ios/features/browse-and-manage-files).

## Download a file

1. Swipe left on a file and tap **Download**, or touch and hold it and choose **Download**.
2. What happens next depends on the file type:
   - Photos and videos are saved to the Photos app. Allow photo library access when asked. BucketMate shows **Saved to photos**.
   - Other files open the Files export sheet. Choose a location to save the file. BucketMate shows **Saved to files**.

When you download several files with multi-select, all of them go through the Files export sheet.

## Copy a presigned link

A presigned link lets anyone with the URL download the file until the link expires.

1. Swipe left on a file and tap **Copy link**, or touch and hold it and choose **Copy link**.
2. Under **Link duration**, tap **30 minutes**, **1 hour**, **1 day**, or **1 week**.
3. BucketMate copies the link to your clipboard and shows how long it is valid.

### Use a custom duration

1. On the **Copy link** sheet, tap **Custom duration**.
2. Enter a number in **Duration** and choose **Minutes**, **Hours**, or **Days**.
3. Tap **Copy link**.

If the duration is longer than 7 days, BucketMate warns that most S3 providers limit link duration to 7 days.

Links cannot be revoked. To invalidate a link early, rename or delete the file.

## Shared link history

BucketMate keeps a local history of links you create.

1. Open it from **Settings** > **Shared links**, or tap **View history** on the **Copy link** sheet.
2. Use **Search by file or connection** to find a link.
3. Tap a link for **Open link**, **Copy link**, or **Delete from history**.
4. Swipe left on a link for **Copy** or **Delete**.
5. Tap **Clear** to remove all history.

Each row shows when the link **Expires** or that it has **Expired**, its duration, and when it was **Created**. Removing a link from history does not revoke it.

## File preview thumbnails (Pro)

With **File preview** turned on in [Settings](/ios/features/settings), file lists show thumbnails for images and videos.

- Supported types: JPG, JPEG, PNG, GIF, BMP, TIFF, WebP, HEIC, MP4, MOV, AVI, MKV, WMV, and FLV.
- Files larger than 100 MB show an icon instead of a thumbnail.
- Thumbnails are cached on the device, so returning to a folder is faster.
- Thumbnails use extra data and can affect scrolling on large folders.
