FixMyFiles vs Online-Convert
Online-Convert is a long-established server-side converter with an unusually deep format list and detailed conversion settings.
By FixMyFiles Updated How we write these
The short answer
Online-Convert has one of the deepest format lists anywhere and exposes settings most converters hide. It is server-side, so files are uploaded and the free tier is metered. We cover less ground but never take a copy of the file.
Online-Convert has been running for a long time and it shows in the coverage: formats other converters have never heard of, and per-conversion settings that go well beyond a quality slider.
It is a service, though, with the trade that implies. Your file goes to their servers, the free tier is metered, and conversions wait behind an upload.
Side by side
No quotas or prices are printed here: they change, and a page quoting them goes stale. For Online-Convert’s current terms, check their site.
| Property | FixMyFiles | Online-Convert |
|---|---|---|
| Where the file is processed | In your browser, on your own device | Uploaded to Online-Convert’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 site |
| 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 Online-Convert’s policy |
When Online-Convert is the better choice
- Formats we have not implemented, including documents, ebooks and archives
- Unusually granular conversion settings for specialist workflows
- Conversions requiring tools that simply do not exist in a browser
When we are
- No upload, so no retention policy matters and no bandwidth is spent
- No metering: convert a thousand images in a row if your laptop will take it
- Every conversion page says what the change actually costs in quality, in plain words
- Offline once loaded, which no server-side converter can be
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
Do you support as many formats as Online-Convert?
No. We deliberately cover images, video and audio properly rather than covering everything shallowly. For documents, ebooks and archives, they are the better choice.
Why would a browser converter be faster?
Because the upload is skipped. Modern browsers encode video with the same hardware your device uses for video calls, and for large files that is usually quicker than sending the file anywhere.
Which formats do you handle?
Every format we read and write is listed on the formats page, with what each one is for and what converting it costs.
