Opening images in FluffyBench Image Viewer

Think of FluffyBench Image Viewer as a light table for digital pictures: the picture tells you what you've got, and the information panel tells you what kind of file it is. You don't need an editor just to identify a scan, check a photo's dimensions, or see whether an image moves.

Here's the job on a phone, from Choose images to the picture and its Image info sheet. Use the visible file properties to check your destination's format, dimensions and file-size requirements.

  1. Choose images opens your file picker. Dropping images here or pasting with Ctrl V are alternatives.

    Step 1. Choose images opens your file picker. Dropping images here or pasting with Ctrl V are alternatives.
    1. Choose images from your device.
    2. Drop images here is another way to open them.
    3. Ctrl V pastes an image from your clipboard.
  2. Use Play to watch the GIF, or Pause to hold a moment. Image info opens the phone’s file details.
    Use Play to watch the GIF, or Pause to hold a moment. Image info opens the phone’s file details.
    Step 2. Use Play to watch the GIF, or Pause to hold a moment. Image info opens the phone’s file details.
    1. Pause holds the animation.
    2. Image info opens the file details.
  3. The paused GIF stays still; Play resumes it.
    The paused GIF stays still; Play resumes it.
    Step 3. The paused GIF stays still; Play resumes it.
    1. Play resumes the animation.
  4. On a phone, Image info shows the file properties. Done closes the sheet.
    On a phone, Image info shows the file properties. Done closes the sheet.
    Step 4. On a phone, Image info shows the file properties. Done closes the sheet.
    1. Read the format, dimensions, file size and frames.
    2. Done returns to the picture.

Format is how the file stores the picture. Dimensions give its width and height in pixels, the tiny squares that make up a digital image. File size is the storage space it takes up. Frames tells you how many pictures make up an animation; it isn't the number of files you've opened.

FluffyBench can also open formats such as TIFF and JPEG XL that a browser's own image preview may not display. See why a browser-based viewer can open more formats.

Find an image in a collection

Enlarging a preview doesn't add detail to the image. For HDR photos, which can store extra-bright highlights, the preview may adjust brightness to fit the display; don't use that preview to judge all the brightness information in the file.

Check a transparent image's edges

A checkerboard means the background is showing through. Compare the same sign cutout on checkerboard and white, including the matching edge close-ups.

A transparent brown sign cutout is shown on checkerboard and white backgrounds, with matching close-ups of a partly see-through edge.

The same brown sign photo cutout on checkerboard and white, with close-ups of a partly transparent edge

  1. Transparent background

    The checker pattern shows through the transparent margin around the brown sign cutout.

  2. White background

    The same transparent surround reveals the white page behind the cutout.

  3. Soft, partly transparent edge

    The same edge can blend into one background and stand out against another.

The same cutout looks different on white and checkerboard, and the close-up shows where the background comes through. How we reviewed · Photo: NPS Photo, Public domain, via National Park Service.

Browse pages inside a TIFF

A TIFF can hold several pages inside one file. Page thumbnails move within that TIFF; Next image moves to another file in your collection.

  1. The TIFF opens at Page 1 of 2. Its page thumbnails sit above the picture.

A preview shows the parts FluffyBench can read; a layered image isn't always a complete set of separate editable layers here. The guide to pages, layers and image surfaces explains the difference.

Other FluffyBench tools

There's no converted file to download from Image Viewer. When the picture needs a change, choose the FluffyBench tool that makes that change.

You need separate TIFF pages, icon sizes or texture surfaces

FluffyBench Image Extractor

Saves image parts it can read as separate files, with labels for texture surfaces.

You need a different format, pixel size or file size

FluffyBench Image Space Saver

Creates a new image for a destination that needs a different kind or size of file.

Before sharing a JPG, PNG or WebP, FluffyBench Remove Image Metadata can remove camera or location tags. The viewer's basic file information isn't a full metadata review.
