What's the same
Where TeraConvert and TinyWow agree.
A comparison is easy to skew. So before the differences, here is what both tools genuinely do the same, so the rest of the page is a fair fight.
- Both convert a wide range of formats across images, video, audio, and documents.
- Both are free to use with no account required to start.
- Both keep the basic flow simple: pick a file, pick a format, convert.
The core difference
One is a free upload site with ads. One runs on your Mac.
TinyWow is genuinely useful and free, and it is upfront that whenever you upload a file it sits on its servers and gets deleted an hour after processing. The catch is the model: it pays for those free tools with ads and CAPTCHAs, and every file has to make the round trip to a server first. TeraConvert works the other way around. There is no server and no upload, so your files are never sent anywhere and there is nothing to show you an ad against.
Straight from TinyWow's data policy.
TinyWow
- Your file uploads to their servers
- It is converted in the cloud, then sent back as a download
- It leaves your device to be processed
TeraConvert
- Converts on your Mac with native engines
- No server, so nothing is uploaded
- Nothing can be kept, leaked, or subpoenaed

Not on a Mac?
The full 800+ format app is macOS only for now, but TeraConvert's free web app runs 200+ conversions right in your browser on any operating system, with the same promise: your files are converted on your device and never uploaded.
Why people switch
What you get by moving to TeraConvert.
Your files never leave the Mac
TinyWow uploads your file to a server, processes it, and deletes it an hour later. TeraConvert skips the upload entirely. The conversion runs on your machine, so there is no copy sitting on someone else's server for that hour, and nothing to trust, leak, or subpoena.
No ads, no CAPTCHAs, ever
TinyWow's free tier is paid for with ads, and its premium plan literally sells removing them plus skipping CAPTCHAs. TeraConvert has no ads on any tier, because there is no ad-supported free site to run. You convert and you are done.
No upload, so no waiting on a round trip
Every TinyWow job has to upload your file, process it on their server, then send it back. On a large file or a slow connection that is the slow part. TeraConvert reads the file straight off your disk and converts it locally, so there is no upload bar to watch.
800+ conversions with real editing
TinyWow covers 200+ tools across categories. TeraConvert Pro covers 800+ conversions and adds local editing on top: trim and crop video, edit PDFs, run OCR on your Mac, and batch-convert whole folders at native speed with no size caps.
The honest bit
When TinyWow is the better choice.
TeraConvert is not for everyone. If any of these describe you, TinyWow is genuinely the better tool and it would be dishonest to say otherwise.
- You want a big free toolset with no sign-up. TinyWow gives you 200+ tools across PDF, image, video, writing, and general files, all usable without an account. That breadth in one free place is a real strength, and TeraConvert's free web tier covers 200+ conversions rather than the whole suite.
- You are not on a Mac. TinyWow runs in any browser on any operating system. TeraConvert's free web app also runs in any browser, but the full 800+ format desktop app is Mac-only for now, so TinyWow covers Windows and Linux users who want everything in one tab.
- You want quick one-off edits beyond conversion. TinyWow bundles writing and AI tools alongside the file tools, so it can be a handy grab-bag when you just need something done fast and do not mind the file leaving your device.
Switching is easy
Moving over takes about a minute.
There is nothing to migrate. No account to move, no files to re-upload, no settings to port. You just start converting.
- 1
Download the app
It is free and installs like any other Mac app. No account needed to start converting.
- 2
Drag your file in
Drop the file you were about to upload somewhere else. Nothing leaves your Mac.
- 3
Convert on your device
It converts locally and saves wherever you want. That is the whole move, no export or import.
Questions about TinyWow and TeraConvert.
Is TinyWow safe?
TinyWow uploads your files to its servers to process them, and its data page says everything, processed and unprocessed, is deleted an hour after processing, and that it does not sell your files or information. That is a reasonable policy for an online tool. But the files still leave your device and sit on a server for that hour. TeraConvert converts on your Mac, so there is nothing to upload and nothing kept on a server at all.
Is TinyWow free?
Yes. TinyWow's core offering is 200+ free tools with no sign-up. It funds that with ads and CAPTCHAs, and a paid tier removes them. Its pricing is region-localized, so it shows Indian Rupees or Japanese Yen rather than a flat US price. TeraConvert is free to download with 200+ conversions, and Pro unlocks 800+ for a one-time $29.
Does TinyWow have ads?
Yes, on the free tier. TinyWow is ad-supported, and its paid plan's main selling point is removing advertisements and letting you skip CAPTCHAs. TeraConvert has no ads on any tier, because it is a local app, not an ad-funded website.
What is the best TinyWow alternative for privacy?
If privacy is the reason you are looking, a local converter is the answer, because the only way a file cannot sit on a server is to never upload it. TeraConvert runs entirely on your Mac. There is no upload, no account needed for the free tier, no ads, and no server that could keep a copy even for an hour.
TeraConvert vs TinyWow: which should I use?
Use TinyWow if you want a big free grab-bag of browser tools on any OS and do not mind your files uploading to a server with ads on the page. Use TeraConvert if you want your files to stay on your Mac, no ads, no upload wait, and 800+ conversions with local editing. As of July 2026 the desktop app is Mac-only, and the free web app runs 200+ conversions in any browser.
Convert files without uploading them.
TeraConvert is free to download and works on your Mac. Pro unlocks 800+ formats, batch conversion, and no size caps for a one-time $29.
