The CloudConvert alternative with no cloud in it.
Convert video, images, audio and PDFs without your files ever leaving your device — no credits, no queues, no privacy policy to trust.
CloudConvert is the swiss-army knife of hosted converters — 200+ formats, an API, sandboxed processing. It's a serious tool. It is also, definitionally, a place your files go: uploaded, converted on someone else's machine, downloaded back, with a free tier metered in 'conversion minutes'.
For the conversions people actually do — HEIC to JPG, MOV to MP4, WAV to MP3, PDF pages to images — none of that infrastructure is necessary anymore. WebAssembly runs the same codecs in your browser, and on a Mac, RenameTo does it with hardware acceleration at native speed. The file stays on your disk the whole time.
| CloudConvert | RenameTo | |
|---|---|---|
| Where files go | Uploaded to their servers | Nowhere — browser or your Mac |
| Usage meter | Conversion minutes | No per-minute meter |
| Speed | Upload + queue + convert + download | Just convert — no transfer time at all |
| Big files | Upload 2 GB first, then wait | No upload; Mac app uses hardware encoding |
| Format range | Broad, including exotic formats | 55 canonical formats in the live matrix |
| Cost | Subscription for real usage | Browser tools free; Mac app $19 once |
Where CloudConvert still wins
Genuinely exotic formats (DjVu, obscure office types), server-side API automation, and converting on a locked-down machine where you can't run anything. If your need is a common format and your file is private or large, skipping the round-trip is faster and safer.
Free, private, no upload. Ever.
This tool runs entirely on your device. It's built by the team behind RenameTo for Mac — where the same job is just a rename in Finder.
