What is TeraConvert?

TeraConvert is an offline file converter and utility toolkit for Mac.

It lets you convert, compress, edit, and process images, videos, audio, PDFs, documents, ebooks, spreadsheets, and more - entirely on your Mac.

It supports 800+ conversions, including formats such as HEIC, RAW, MKV, FLAC, PDF, DOCX, XLSX, EPUB, SVG, and many others. Files are processed locally and are never uploaded to a server.

But TeraConvert goes beyond simple file conversion. It also includes built-in tools for editing existing PDF text, merging and splitting PDFs, OCR, background removal, image and PDF compression, SVG tracing, and audio/video trimming.

Who is it for?

TeraConvert is built for Mac users who regularly work with files but don't want to upload private documents or large media files to online converters.

It's especially useful for developers, designers, photographers, video creators, freelancers, students, and professionals working with confidential documents or large batches of files.

You can use it for anything from converting a folder of RAW photos to JPEG, fixing a typo inside a PDF, trimming a video, extracting text from a scanned document, or converting a large MKV file - without sending the file anywhere.

How is it priced?

TeraConvert uses a one-time purchase instead of a subscription.

Your first conversion is free, so you can try the app before purchasing Pro. The Pro license unlocks the full desktop experience, including unlimited file sizes, batch and folder processing, and the complete set of conversion and editing tools.

There are no per-file charges and no watermarks, and purchases include a 14-day money-back guarantee.

How does it compare to alternatives?

Most file converters are websites: you upload a file, wait for it to be processed on somebody else's server, and then download the result.

TeraConvert takes the opposite approach.

Everything runs locally on your Mac.

That means:

No file uploads
No upload or download waiting
No practical desktop file-size cap
No subscription required
Batch entire folders
Works without an internet connection
Sensitive documents stay on your computer

The desktop app uses local engines for media, PDFs, OCR, documents, and other formats rather than sending files to a conversion API.
