The best free online file converters, compared
Online converters handle hundreds of formats, but they run the conversion on their servers and limit free use. Here is what each one gives you for free, from its own pages, and when a converter that runs in your browser is the better pick.
We make File Converter, one of the tools on this page. Every fact about the other tools comes from their own pages, linked under each one, as they read on 2026-10-24. Prices and features change: check each site before you choose.

Questions
Is there a file converter that does not upload my files?
Yes. File Converter runs every conversion in your browser, so the file stays on your device. CloudConvert, Convertio and FreeConvert upload the file and convert it on their servers.
Which free converter has no daily limit?
File Converter has no daily cap, because the work happens on your computer. CloudConvert gives 10 conversion credits a day and FreeConvert 20 conversion minutes a day on their free plans.
Can I convert Word to PDF here?
Yes. File Converter turns .docx files into PDF with the Documents engine, in your browser, and PowerPoint .pptx files into PDF with the Presentations engine. Old .doc and .ppt files need saving as .docx or .pptx first.
Can it convert video?
Yes: MOV to MP4, video to WebM or GIF, a frame to a picture, and video or audio to MP3 or WAV. It runs on your device, so long videos take a while on slower computers.
