Why Convertly Wins
Three fundamental advantages that apply across every comparison.
Privacy by Design
Every other converter uploads your files to their servers. Convertly processes files entirely in your browser using WebAssembly. Your files literally never touch the internet.
Truly Unlimited
No file size limits. No daily conversion caps. No premium tiers. No ads. No watermarks. Convertly is 100% free with zero strings attached — because there are no server costs to pass on to you.
Instant Processing
Server-based converters need to upload your file, process it, then send it back. Convertly skips the round trip — processing starts the moment you drop a file. Large files that take minutes to upload are converted instantly.
