The file converter that never uploads your files

TeraConvert converts files directly on your device, so nothing is ever uploaded to a server. Use it free in your browser for images, videos, audio, PDFs and documents. When you need heavy formats, batch processing, or OCR, there’s a Mac app powered by trusted conversion engines. No uploads. No subscriptions.
Hi Product Hunt! 👋
The idea behind TeraConvert started with a simple question.
Why do I have to upload a private file just to change its format?
Whether it’s a passport, signed contract, tax return, family photo, or work document, most file converters ask you to upload it to a server you know nothing about.
That never sat right with me.
So I built TeraConvert around one simple principle:
Your files should stay on your device.
Want proof?
Open TeraConvert, disconnect from Wi-Fi, and convert a file. It still works.
That’s because your files never leave your device.
The free browser version converts images, videos, audio, PDFs, documents and more entirely on your device.
When you need heavier conversions, batch processing, OCR, or advanced editing, there’s a macOS app powered by trusted conversion engines like FFmpeg, ImageMagick, Ghostscript, Pandoc, LibreOffice, and Tesseract.
I didn’t build another website that uploads your files to a server.
I built a file converter that keeps them with you.
TeraConvert is still evolving, and many features exist because someone asked for them. I read every email, feature request, bug report, and Product Hunt comment.
I’d genuinely love your feedback.
What’s one file conversion you’ve always wished just worked?
If TeraConvert doesn’t support it today, tell me. I’d love to build it.

Thank you so much for checking out TeraConvert. I truly appreciate your time, feedback, and support. ❤️
This looks really handy, especially the local processing angle since I never trust random converters with sensitive docs. One thing that would make it way more useful for me though is a folder watching feature where you drop files into a specific folder and it automatically converts them to a preset format, basically cutting out the click-through entirely for repetitive tasks.
@glseren314996 Thanks. I really appreciate the suggestion.
Watched folders don’t exist yet. Right now you can drop files in and convert them in batches, but there’s nothing that automatically watches a folder.
I really like your idea though. If you don’t mind me asking, what’s the repetitive workflow you’re trying to automate? I’d love to understand the real use case.
The on-device approach is genuinely refreshing, especially for anyone handling sensitive documents. One thing that would make this a daily driver for me is drag and drop folders directly onto the browser tab, with the option to preserve the original subfolder structure in the output. Right now I imagine converting a batch means re-organizing everything manually afterward.
Thanks so much @yaardeveciektr Really appreciate the thoughtful feedback 🙌
The desktop app already lets you drag folders in for batch conversion, but you’re absolutely right about preserving the original folder structure. That would make large batch workflows much smoother.
I really like this idea, and it’s definitely something I’ll be exploring.
Out of curiosity, what kind of files are you usually converting in batches?
The privacy-first approach is a big deal, especially for sensitive docs. One thing I'd love is a Linux version of the desktop app since I split time between Mac and a Linux workstation and right now I'd be stuck using the browser there. Would make the paid tier way more useful for folks in mixed-OS setups.
@abdullahye5c6w Thanks. Really appreciate that. Linux has come up a few times now, so it’s definitely on my radar. I started with macOS so I could keep the scope manageable as a solo developer, but I’d love to support Linux too. Out of curiosity, what’s your Linux distro and your typical workflow?
