Any file, converted on your machine.
Every converter site wants your files on their server. Offline Convert does the top thirty operations people upload files for — merge, compress, transcode, OCR — locally, in a native app that opens in under a second.
What it does
PDF merge/split/compress, HEIC→JPG, video compress, MP3 extract, images→PDF, password add/remove — no daily caps, no watermarks.
Drop 200 files. A persistent queue processes them with per-file progress and errors — one bad file never kills the batch.
A ~10 MB native app that opens in under a second and idles near zero RAM — not a 512 MB server in a browser tab.
File-type detection by content, not extension — drop a file and see exactly what you can do with it.
The same engine ships as a CLI: offline-convert pdf merge a.pdf b.pdf. Automate everything.
Every operation writes new files. Your inputs are never modified.
