SVG Viewer is an Android app that allows users to visualize Scalable Vector Graphics (SVG) files stored on their smartphone. It offers a simple, intuitive interface with no ads and works offline. The app can open SVG files from file explorer applications, Dropbox, OneDrive, and Google Drive. It also supports SVGZ file format and works perfectly with Inkscape-generated files.

One of the key features of SVG Viewer is its ability to display large SVG files without exceeding the screen size. The app offers two possibilities to view files: using a native library implementation or web view engine, which can be set in the settings view. Additionally, the app converts opened files to PNG, which is a paid feature, but you can still make screenshots in full-screen mode with moderate quality.

SVG Viewer is a must-have app for designers and developers who want to view how created icons will look on multiple Android devices. The app offers advanced features like recent viewed files, multiple documents selection, editing the file layers, saving in PNG format, full-screen view, and more.

Finally, the app allows users to open Gmail attachments using Google Drive app. However, some SVG files with custom fonts may not be rendered, so it's best to use an editor that can export text as independent line curves.
