Why use online tools instead of installed apps?

No install, no signup, nothing to update, and they work on any device - phone, school laptop, work computer. Browser-based tools also keep your files on your device, which matters for assignment submissions and client work.

Are these tools really free?

Yes - completely free, no signup, no premium tier, no watermarks. Convert Freely is funded by displaying a few non-intrusive ads on the homepage. The tools themselves are clean.

Will these work on a school-managed Chromebook?

Almost always - they're web pages, not apps. No install permissions needed. Some school networks block specific domains, in which case you may need to use your home network.

Can I use these for paid client work?

Yes. Convert Freely is privacy-first by design - your files never leave your device - which makes it appropriate for client documents, NDAs, and sensitive material.

What if I need an offline option?

Open Convert Freely once with internet. After that, your browser caches the page and the tool works offline. Perfect for travel, exams, or unreliable WiFi.

Submitting assignments as a single PDF

Convert any HEIC photos with HEIC to JPG.
Use Image to PDF to turn scans / screenshots into pages.
Use Merge PDF to combine with your essay or cover letter.
Use Compress PDF if the result is over the upload limit.

Total time: ~3 minutes for a 20-page submission.

Use keyboard shortcuts in your file manager to multi-select files before dropping them into a tool.
