Let us sort out the disclosure right from the start: we are the makers of FormatFusion, a product that directly competes with FreeConvert. You should read the following the same way you would read a Ford dealer's evaluation of a Toyota. What we can guarantee is that all the claims made here are verifiable, and that we will clearly tell you when FreeConvert is in fact the better choice, since there are situations in which it is.
What FreeConvert genuinely does well
FreeConvert is one of the biggest converter sites on the internet, and it didn't get there by accident:
- A huge catalog offering ebooks, archives, fonts, vector formats, and unit converters, covering a great deal of the long tail. If you need to convert EPUB to MOBI or any format you've come across twice in your life, they'll almost certainly have a page devoted to it.
- Tools for compression. Specialized compressors for video, images, and PDF files, aimed at hitting a specific file size. Truly useful, and something we do not currently offer.
- Powerful servers. Since the conversion happens on their computers, a weak laptop can convert an hour of 4K video at data-center speed, and file size limits on the paid plans are generous.
- An API for developers who want conversion inside their own products.
If the things you work on every day depend on those, use FreeConvert and never look back. No hard feelings.
The two differences that actually matter
For the kind of conversions most people carry out most days (images, audio, video clips, documents, spreadsheets), the choice comes down to two structural differences rather than a list of features.
1. The destination of your files
FreeConvert operates the way most converter websites do: you upload your file to their servers, it is processed there, and you download it back. They state that files are deleted automatically a few hours after upload, and we have no reason to question that they keep to this policy. However, deletion after upload is a matter of policy only. You cannot verify it, and as long as the file remains on their systems it is exposed to all the risks that apply to data held on servers: breaches, misconfigurations, legal requests, and employee access.
FormatFusion works differently. The conversion engines are compiled into WebAssembly and operate within your browser. When you convert a PDF to Word or HEIC to JPG on this site, the file moves from one folder on your device to another and never travels over the network at all. Since nothing ever reaches us, there is nothing for us to delete. When it comes to contracts, identification documents, medical records, and any files with your children's faces in them, this difference makes all the difference.
2. How you pay
The free tier offered by FreeConvert is metered: limits on file size and daily conversion minutes, with the system designed so that regular users are moved toward a subscription. The paid plans are monthly, the top Pro plan costing $29.99 a month, which is about $360 a year, every year, for as long as you need it. Middle tiers are cheaper per month but keep the meter going in other ways.
The free version of FormatFusion is supported by ads and allows files up to 1 GB each, three per batch, with no daily meter, no watermarks, and no need for an account. FormatFusion Pro costs $29 once, not monthly, not annually. It gets rid of the ads and the size restriction, enables unlimited batches with one-click ZIP download, and includes output controls such as quality sliders and bitrate settings. A single month of FreeConvert Pro costs more than our Pro costs forever.

| Compression tools | Yes | Not yet |
| Speed on everyday files | Upload, queue, process, download | Starts instantly, no upload time |
The speed question
With a 5 MB picture, an upload-based converter spends most of its time uploading the file and waiting in the queue. A conversion carried out locally starts the very moment you click and is completed before the server would have finished receiving the file. In the case of a 2 GB video, the arithmetic changes: your laptop is outdone by the data center. Choose the architecture that suits your files.
Who should pick FreeConvert
- You work with formats outside the mainstream, such as ebooks, fonts, CAD files, and rare archives.
- You usually deal with video files larger than approximately 1.5 GB.
- You need compression to reach a certain file size, or OCR, or an API.
- Your hardware is rather weak and you convert long videos frequently.
Who should pick FormatFusion
- Your conversions are the usual kind: photos, audio, video clips, documents, spreadsheets.
- The files are private and you would prefer they never reach anyone's server, regardless of any policy.
- You have an allergy to subscriptions and meters.
- You want to convert right now, without creating an account, on any device with a browser.
The short version
FreeConvert is a large, capable, server-based converter that operates on a subscription basis, and it is the appropriate choice for heavy or unusual tasks. FormatFusion is a private, local, browser-based converter with a pay-once model, and it is the right option for the files you actually convert each week. Test the free tier of both services with the same file and see which one you would rather live with. Ours is one click away and does not ask for an email address.
