How to use AsapView

Beyond the viewer window: open, convert and print straight from File Explorer, or automate it all from the command line.

Explorer right-click menu

Open, convert or print images straight from File Explorer, without opening AsapView first.

Image files

Right-click an image and choose AsapView › Open, Convert… or Print…. Select several files and choose Convert… or Print…, and they all open in a single AsapView window, gathered in the basket.

Folders

Right-click a folder, or the empty space inside one, and choose Open with AsapView to see it as a thumbnail grid.

Windows 11 and Windows 10

On Windows 11 these items are under Show more options, or hold Shift while you right-click. On Windows 10 they appear directly in the menu.

Turning it off

To hide the items, open AsapView's right-click menu and turn off Show in Explorer right-click menu. Uninstalling AsapView removes them automatically.

Command line and silent print

The installer adds asapview-cli.exe. Tick Add asapview-cli to PATH during setup to run it from any folder. It prints and converts without opening a window, and returns an exit code your script can check.

Good for

Kiosk and photo-booth printing
Scheduled batch conversion with Task Scheduler
Scripts and automation

Files can be single files, folders or wildcards such as *.jpg.

`--layout fit\|fill\|2\|4\|6\|9\|12\|20\|4x6\|5x7\|wallet\|id`	`fit` or `fill` for one per page, `2` to `20` per page for contact sheets, or the photo sizes `4x6`, `5x7`, `wallet` and `id`.

`--captions`	Print the file name under each photo.
`--no-rotate`	Don't rotate photos to fit the page.
`--output <file.pdf>`	For PDF and other file printers: save to this file without a Save dialog.

Convert options

Option	What it does
`--to jpg\|png\|webp\|avif\|gif\|bmp\|tiff\|ico\|tga\|qoi\|jxr`	Output format.
`--quality 1-100`	Quality from 1 to 100. For WebP, 100 means lossless.

asapview.exe accepts the same arguments, for example --print … --silent. In scripts, use asapview-cli instead: the console waits for it to finish and receives the exit code.
