What Is a PNG File?
A PNG file is commonly recognized by the .png extension. These files are used in everyday document, image, data, development, or publishing workflows where the format needs to be opened, inspected, cleaned, converted, merged, or prepared before sharing.
When Should You Use PNG?
PNG is useful when your workflow expects this file type and you want a reliable way to preview, review, transform, or clean the file without installing extra software. The tools on this page focus on practical browser-based tasks for png files.
Common PNG Tasks
Common png tasks include viewing file contents, checking that the file opens correctly, merging related files, converting to nearby formats, cleaning hidden or unnecessary content, and preparing a safer copy for upload, publishing, testing, or sharing.
Browser-Based PNG Tools
