Got a file in the wrong format and no patience for installers? Convert anything to anything — PDF to Word, MP4 to MP3, PNG to JPG — all free, all online, zero signup nonsense.
🕐 Updated June 2026 · 6 sectionsSomeone sent you a .pages file. Your boss needs that PDF as a Word doc. Your video is in the wrong codec. We've all been there — and these 6 converters handle everything from images to videos to CAD files, no account needed.
CloudConvert handles 200+ file formats — documents, images, videos, audio, ebooks, archives, even CAD files. It's the one tool that covers basically everything. Free: 25 conversions per day, files up to 1GB, no signup for basic use. This is our go-to recommendation.
Convertio has the cleanest UI in the game — uploading from Drive, Dropbox, or URL feels seamless. Supports 300+ formats. But the free tier caps you at 10 conversions/day and 100MB per file. Great for occasional use, annoying for power users.
Zamzar has been converting files since 2006 — that's practically ancient in internet years, and they've processed over 500 million files. 1100+ format combos. The free tier is tight (2 files/day, 50MB each), but it just works every time.
Unlike most converters that give you zero control, Online-Convert lets you adjust quality, resolution, bitrate, and other settings pre-conversion. Supports audio, video, images, docs, ebooks, archives. Generous free limits, max 100MB. The control freak's choice.
Most converters make you do one file at a time, which is maddening. FileZigZag does batch — drop a folder of 20 images and convert them all at once. Supports 180+ formats. Free: 10 conversions/day, files up to 50MB. Real time-saver.
If you're mostly converting videos and audio, FreeConvert is where you should land. Advanced codec options, bitrate control, resolution changes, and even video trimming before conversion. Free: 25 minutes of video processing/day, files up to 1GB. Actually useful for real projects.
Reputable converters delete files after processing (typically within 24 hours). For sensitive files, use offline tools or check each site's privacy policy before uploading.
