convert.now vs Convertio
Both convert files. The difference is architectural, and it decides which one you should use for a given job.
The short answer
Convertio uploads your file to a server, converts it there, and sends the result back. convert.now runs the conversion in your browser, so the file never leaves your device. Convertio supports far more formats; convert.now is faster on ordinary files and requires no trust.
Background
What Convertio is
Convertio is a general-purpose online file converter that handles a very wide range of formats — documents, ebooks, video, audio, CAD, archives — by uploading your file to their servers and converting it there.

Honest answer
When Convertio is the better choice
- You need a format a browser has no codec for — video, CAD, ebooks, or most office documents.
- Your file is large enough to exhaust a browser tab's memory, roughly half a gigabyte and up.
- You need OCR, or any conversion that requires real server-side compute.
Honest answer
When convert.now is the better choice
- The file is confidential — a contract, an ID scan, medical or financial records, unreleased work.
- You are converting images, PDFs, spreadsheets, data files, fonts or audio, which is most everyday conversion.
- You have a batch to get through and do not want to hit a daily cap.
- You are on a slow or metered connection, where uploading is the slowest part of the job.
