Zamzar has been converting files online since 2006 — one of the originals. But the free tier caps files at 50MB, limits you to 2 conversions at a time, and used to require an email address to receive results. Their paid plans run $13-$25/month.
In 2026, uploading files to a server for conversion feels dated when browsers can handle the same work locally. Here are 18 free conversion tools that work without uploads, without email, and without size limits.

Zamzar's free tier limits files to 50MB. A single 1080p video is often 200-500MB. Even their $13/month Basic plan only bumps the limit to 200MB. Our tools process locally — the limit is your device's memory, not an arbitrary paywall cap.
Zamzar historically required an email to receive converted files. They have moved past this, but still push account creation for file history and faster processing. Our tools require nothing — open the page, drop your file, download the result.
Zamzar uploads, converts on their servers, then stores your file for download. Your documents and videos sit on their infrastructure. Browser-based tools process everything locally — nothing leaves your device, nothing is stored anywhere.

Browse All Converter ToolsTo be fair, Zamzar has strengths that browser-based tools cannot match:
Zamzar is a reliable, long-running service that supports hundreds of formats. For document, e-book, and specialized conversions, it remains useful.
But for the conversions most people need — video, images, PDFs, and data formats — browser-based tools are faster, more private, and have no size limits. Try our 18 free conversion tools before paying Zamzar $156/year.
