FixMyFiles vs Convertio
Convertio is a browser-based interface to a server-side conversion engine, covering a very wide list of formats.
By FixMyFiles Updated How we write these
The short answer
Convertio and FixMyFiles look similar — drop a file in a web page, get a converted one back. The difference is underneath: Convertio sends the file to its servers to do the work, and its free tier is metered by file size and volume as a result.
Convertio is deservedly popular: the interface is clean, the format list is long, and it handles document and ebook conversions we do not attempt. If you have ever converted something on a phone in thirty seconds, there is a good chance it was here.
The thing worth knowing is that the conversion is not happening in your browser. The page is a front end; the work is on their machines, which is why there is a size cap on the free tier and why a large video takes as long to upload as it does to convert.
Side by side
No quotas or prices are printed here: they change, and a page quoting them goes stale. For Convertio’s current terms, check their pricing page.
| Property | FixMyFiles | Convertio |
|---|---|---|
| Where the file is processed | In your browser, on your own device | Uploaded to Convertio’s servers |
| Upload required | No — there is no upload endpoint | Yes, that is how it works |
| Account needed | Never | Not always, but the free tier is metered without one |
| Free tier limits | None; your device’s memory is the only ceiling | Metered — see their pricing page |
| Watermarks | None, ever | No watermark on converted files |
| Works offline | Yes, once a page has loaded | No — it needs the connection to upload |
| Speed limited by | Your CPU and GPU | Your upload speed, then their queue |
| File retention | Nothing leaves the tab, so there is nothing to retain | Held while processing, then deleted per Convertio’s policy |
When Convertio is the better choice
- Documents, ebooks and archive formats, which we do not convert
- Converting from a cloud source — Dropbox, Google Drive, a URL — without downloading it first
- Conversions too heavy for a modest phone, where a server genuinely helps
- A long tail of obscure formats we have not implemented
When we are
- Nothing is uploaded, so the free tier has no size cap to hit
- No queue: your device starts the moment you choose the file
- No account, no credits, no daily conversion count
- Batch work is limited by your CPU rather than by a plan
The one difference that does not change
Every service on this page is built the same way: your file is uploaded, converted on their machines, and downloaded back. That is not a flaw — it is what lets them convert formats a browser cannot open, and run work a phone could not finish.
It does mean a copy of your file exists somewhere you do not control, for as long as their policy says. For a stock photo that is irrelevant. For a passport scan, a recording of a meeting, an unreleased edit or a photo of your children, it is the whole question.
There is no upload here — not a disabled one, not one behind a flag. The site is static files and none of them accept a file, which is why the claim can be checked rather than trusted: watch your own network panel stay empty while a file converts.
Questions
Why does Convertio limit free file sizes?
Because every conversion costs it bandwidth and server time. We have no equivalent cost — your device does the work — so there is no limit to impose.
Can I convert HEIC, MKV or FLAC here instead?
Yes. HEIC to JPG, MKV to MP4 and FLAC to MP3 all run locally, with no size limit.
Is one more private than the other?
Structurally, yes. Privacy on a server-side converter depends on its policies and its security; here there is no copy of the file to protect, because it never leaves the tab.
