About UltConvert

What you can do here

The tools cover images, PDFs, documents and data, video and audio, plus a set of everyday converters and calculators: compress a picture to an exact size, resize it in pixels or centimetres, turn HEIC into JPG, merge or split PDFs, convert Word files to PDF, shrink a video for a chat app, extract audio, convert units and time zones, or work out the days between two dates.

Each tool is a page built for one task, with sensible settings already filled in. Use it without an account, without installing anything and without a watermark on the result.

How the pages are made

A page about a requirement should show the requirement. Pages for passport photos, exam forms or social media sizes quote the figures published by the organisation that sets them, link that official source and show when we last checked it. When a figure cannot be confirmed from an official source, it is left out rather than guessed.

Longer explanations live on the blog, where each guide names its author and the date it was last reviewed. Because rules change, the Disclaimer explains why the official page always has the final word.

Your files

Files are uploaded only when you press the convert button, processed for that job alone and deleted automatically: the original once the result exists, the result 30 minutes after processing. The unit, time zone, date, color and developer tools never upload anything; they run entirely in your browser. How it works walks through each step, and the Privacy Policy page lists the data that is collected.

Why it is free

UltConvert is paid for by advertising served by Google AdSense. There is no paid plan, no trial that runs out and no feature held back for subscribers. Choosing whether to allow personalized ads has no effect on what the tools can do.

Who runs UltConvert

UltConvert is operated by UltConvert Media. We read every message sent to [email protected], whether it reports a bug, corrects a figure, suggests a tool or concerns a legal matter. The contact page explains what to include so we can help quickly.
