What these articles are for

Each article helps you choose a format or a limit before you convert. They are not a substitute for the form you are about to submit, the university transcript, or the carrier app. Passport sizes, CGPA scales, and eSIM steps change. The article tells you what to verify and which tool matches the job after you have verified it.

The tool page is still the place that states what the download contains. An article about PDF to Word will not make the converter rebuild a designed layout. An article about MP3 and WAV will not make a lossy file sound new. Read the article, then open the tool, then read the limit on that page.

Dates on the posts are updated dates. The practical advice is written for current browsers and current portals, and it still tells you to read the live rule when a third party controls the number. Files in the linked tools stay in your browser, except YouTube tools, which send only the link.

If an article and a tool page disagree, trust the tool page. The tool page is updated to match what the button does. The article is there to help you choose. It should not be read as a promise that a portal, a university, or a carrier still uses yesterday's number.
