Archonex Converter

Archonex Converter converts files on your own device. Nothing is uploaded, nothing is queued behind somebody else's server, and there is no artificial cap on how large a file can be. Most free converters stop at 100 MB and send your files away to do the work. This one runs the conversion locally, at the real technical ceiling of your device — up to 2 GB per file on Android. WHAT IT CONVERTS • Video and audio — MP4, MKV, WebM, MOV, GIF, MP3, WAV, FLAC, AAC, OGG and more. Quality presets for the common cases, and per-file control over resolution, frame rate, bitrate and audio when you want it. • Images, in batches — JPG, PNG, WebP, BMP and TIFF, up to thirty photos in a single run. A failure on one photo stays on that photo instead of ending the batch. • PDF, in both directions — turn photos or text into a PDF, or take a PDF apart into images. WHY IT IS DIFFERENT • Fully offline. Your files never leave the device, so nothing can be retained, leaked or read by anyone else. • No account. Nothing to sign up for and nothing to sign in to. • No adverts, no tracking, no analytics of any kind. • Open source, under the Apache 2.0 licence. FREE AND PAID The free tier includes ten source files every calendar month — every converter, every format and every file size, with nothing held back. The count refills on the 1st. Only conversions that actually succeed are counted. A run you cancel, a run that fails and an unreadable photo in a batch of thirty all cost nothing. A subscription lifts the count entirely: $0.99 per month, or $7.99 per year. Subscriptions are billed through Google Play and can be cancelled there at any time. HONEST LIMITATIONS We would rather tell you these up front than have you discover them: • Text to PDF covers Latin, Greek and Cyrillic. Chinese, Japanese and Korean text is refused with a clear message rather than drawn as blank boxes. • HEIC and AVIF can be read as sources but not written as results — no encoder for them ships in the bundled engine. • Very large files can run out of memory on some devices. Saving a result can briefly hold two to three times its size, and 2 GB is the platform's hard ceiling rather than a comfortable margin. Archonex Converter is also available for Windows and Linux.
