View Photos and Exif Tags with EasyPicViewer PWA

The Web App provides a sophisticated frame for viewing photo files. As a special feature, you can view and export a list of Exif image metadata of each photo.

Purpose of Use

With the basic version of the Web App, image files can be opened and viewed via the file dialog.

As an additional feature, a list of Exif image metadata can be displayed.

Views

The preview of the loaded pictures can be viewed in a gallery view or in a scrollable view.

After clicking on a preview image, the original opens and the dimensions are adjusted to the window dimensions.

Progressive Web App

EasyPicViewer PWA can be installed for use with a browser. The PWA can then be launched like other apps and can be used offline, too.

For installation, the browser shows an icon in the address bar and/or an entry in the browser menu. Uninstall can be done from the PWA menu.

After clearing the browser cache, the next start of the PWA is only online possible.

Database Usage

For optional features and optimizing the memory requirement, a browser-integrated database interface (IndexedDB) is used.

By this, the original and copies of the selected images are saved along with properties after completing the file dialog.

Then it is possible to change the image preview order. One setting enables the automatic loading of the preview of the last stored images when the app is started.

The use of the database for displaying the images can be deactivated. This also deletes all stored entries of the images.

The database menu is opened in the Gallery View by using the Page Keys or horizontal Swipe.

The app can be used with a browser, which has IndexedDB not implemented.

Methods of Input for all Functions

In the app, the inputs via Mouse, keyboard and Touch for all functions are listed.
