Essential File Converter Tools for Every Format | 22
Update: Sep 7, 2026 · 448 apps reviewed
File converter tools make it possible to move content between formats without rebuilding it from scratch. The best options handle document, image, audio and archive conversions cleanly, while preserving layout, quality and metadata wherever possible. Choosing well means looking at batch processing, drag-and-drop simplicity, format support and whether the app works offline for sensitive files. Strong converters also reduce the friction between everyday tasks like turning PDFs into editable documents, resizing image libraries or preparing files for different devices and platforms.

CubePDF keeps PDF creation simple by behaving like a virtual printer, so anything that can print can be turned into a PDF without extra steps. It suits everyday office and personal workflows, but it is focused on PDF output rather than broad format-to-format conversion.

The extension keeps PDF-to-image work close to the browser with drag-and-drop input, page previews, and file details up front. The newer web-page converter adds another route for conversion, but this remains a lightweight tool rather than a full document-processing suite.

The tool is narrowly focused on turning images into Base64, which makes it handy for developers who need a fast browser-side conversion step. It does not promise batch processing or broad format coverage, so I’d treat it as a lightweight utility rather than a full conversion suite.
