How it works

1

Install

Drop Lazyfile into Applications. It runs from the menu bar.

2

Rename

Change a file's extension in Finder. That's the entire interface.

3

Done

Lazyfile converts in the background. Your file is ready.

Example

→ You rename report.docx to report.pdf
→ Lazyfile detects the rename and converts the file in place
→ You get a real PDF — same name, same place, ready to share

Quick questions

Can't I just convert files in Preview?

You can. Quick Actions handles a few image formats with 3–4 clicks per file. Lazyfile handles 30+ formats with zero clicks — and works on documents, spreadsheets, and presentations too.

Is my data safe?

Everything stays on your Mac. No internet required. No telemetry. No tracking.

What if a conversion fails?

Lazyfile restores your original file automatically. Your data is never lost.
