About Convertek
Convertek (www.convertek.tech) is a free online file converter for images, documents, data, audio, video, archives, fonts, subtitles, presentations, and ebooks — no watermarks, fair upload limits, and results you keep in your own browser.
Last updated: August 28, 2026
Mixed-type batch
Drop PNG, PDF, MP3, and more in one queue — no need to split uploads by file type.
Per-file formats
Choose a separate output format for every file. You are not locked into one target for the whole batch.
Privacy-first
Files are processed temporarily on the server. Converted downloads stay in your browser storage.
No watermarks
Free conversions without branding your images, documents, or exports.
How conversion works
Upload a file or batch, pick target format(s) for each item, and we convert on the server using engines suited to each type. When conversion finishes, you download the result. We do not keep a permanent personal cloud library of your files after processing.
Accounts & history
Guests can convert freely within fair limits. Creating an account unlocks synced bookmarks and durable conversion history in this browser for your sign-in. Bookmarks are stored with your account so you can reuse favorite conversion pairs.
