Researched and fact-checked by Bartu Cavusoglu · Updated October 26, 2026
ConvertFast is a desktop file converter and toolkit for Windows, macOS and Linux. It handles conversion, compression, editing, OCR, protection and organization in one app, and its core processing runs on your own computer instead of an online service.
The product supports 134 formats and 2,388 conversion paths, and its page title cites 69 dedicated tools. It is sold as a one-time purchase, which sets it apart from upload-based converters and recurring subscription suites.
You install the app and choose a toolkit: Convert Files, PDF Toolkit, Image Toolkit or Audio / Video. Each tool has its own settings, and files are processed on your device. The company states that no files are uploaded, and that core file work runs offline.
Jobs can run on single files or whole folders. Batch processing includes controls for output quality, file naming, metadata and destination folders, so repeated exports can follow the same rules each time.
The PDF toolkit covers merging and splitting, extracting or reordering pages, comparing revisions, removing metadata and adding password protection. OCR makes scanned documents searchable, and PPTX files can be compressed while staying editable for email.
The image toolkit resizes, cleans and converts files, including HEIC and camera RAW formats such as CR3. Audio tools normalize, trim and extract tracks, while video tools compress, add subtitles and remux. Nineteen utilities handle renaming, sorting, comparing, syncing and verifying files.
ConvertFast is a desktop app for Windows, macOS and Linux that converts, compresses, edits, OCRs and organizes files locally. It supports 134 formats and 2,388 conversion paths, with PDF, image, audio, video and utility toolkits.
ConvertFast is a one-time payment of $24.99, shown as a 50% discount from the regular price of $49.99. There is no subscription, and the license includes future updates and priority support.
The sources do not mention a free trial. The site offers an interactive demo of the workspace, but real conversions are available to paid users only.
No. The company states that core file processing runs locally on your computer, so files do not need to be sent to an online converter.
Yes. The site says core file work runs offline, which differs from online converters that need an internet connection for every file.
ConvertFast runs on Windows, macOS and Linux. One license can be used on two devices.
It covers documents such as PDF, DOCX and PPTX, images including HEIC and camera RAW, audio such as MP3 and FLAC, video such as MP4 and MKV, and some 3D formats. It also offers OCR, compression, metadata removal and batch processing.
It suits small businesses that work with client files, repeated exports and office PDFs, since it is a one-time purchase and keeps files local. Teams needing more than two devices per license should check the terms before buying.
