Who makes Filoshi

Filoshi is made by Ismail, an independent developer. There is no company behind it with investors or a sales team: one person designs it, writes it, tests it and answers the support email. The terms and privacy policy name Synvor, the name Filoshi is published under.

Why it exists

Most free converters ask you to upload your file to their server, convert it there and send it back. That is fine for a meme and a bad idea for a contract, a passport scan or a family video. Filoshi does the same job on your own PC: the engines (FFmpeg, ImageMagick, Pandoc, PDFium, pdfcpu and 7-Zip) ship inside the app, so a file never has to leave your computer. It is a one-time purchase, with no account and no subscription, and a character who eats the files you drop on it, because a utility can be nice to use too.

The story so far

• February 2026: the first release, Filoshi 1.0. The 1.0 line ended with version 1.0.36, which Mac and Linux users still download today.
• October 2026: Filoshi 2.0.0 for Windows, rebuilt around the character, with a file viewer, a PDF Suite, the island and the taskbar buddy. Mac and Linux keep version 1.0.36 for now.

How conversions are tested

Every conversion the app lists has an entry in an automated test matrix. For each one, a small real sample file is converted with the same engines the app ships, and the result is checked to be a valid file of the target format. On the last run (Windows 11, 2026-10-24), 1,841 conversions passed with 0 failures. The app lists 2,501 in all: 220 need a free add-on (LibreOffice or FreeCAD), which the test machine does not install, and 440 have no sample file yet. The site says which is which on every conversion page.
