First, the usual disclosure: we build FormatFusion, a product that competes with CloudConvert. Take that into account and check the links. All the information below is taken from CloudConvert's own published pages and public reviews as of September 2026.
It should also be said from the start that, of all the major converter services, CloudConvert is the one we'd defend at a dinner party. Its privacy policy makes it clear that all processing is carried out by machine without any human involvement, that files are deleted at the latest 24 hours after processing, and that there is an actual delete button that removes them immediately. The API is truly good, the list of formats is extensive, and the documentation gives an honest account of its own billing. If your requirement is conversion inside an automated pipeline, CloudConvert is a suitable tool developed by serious people.
The question is whether you, a person with some files, should be paying for conversion by the credit.
How the credit meter works
CloudConvert measures everything in credits. According to their pricing page, a credit is equivalent to about one minute of processing, and the base cost varies by job type: converting an Office document to PDF costs 2 credits, while PDF back to Office costs 4.
The free tier provides 10 credits each day, together with a 1 GB file size limit, a maximum processing time of 5 minutes per job, and low queue priority. It seems like ten conversions until you take the per-minute metering into account: one long video can use up the whole daily allowance by itself, and any job needing more than 5 minutes of processing is excluded from the free tier entirely.
Beyond the free tier you purchase credit packages (which never expire) or subscriptions (lower cost per credit, reset monthly). What does this amount to in dollars? Here the transparency slips: the official pricing page displays its figures through a slider that doesn't show fixed prices, and third-party listings such as Capterra put the starting price around $8. Regardless of the exact amount, the structure is the point: you are paying in advance for metered server time, and the heavier the job, the faster it burns.
Where the meter chafes
CloudConvert has a small but decent review base (4.5 on Trustpilot across 71 reviews), and the negative reviews cluster exactly where a metered server model should hurt. One reviewer describes a video job on a paid minutes package that ran for hours and eventually produced a file six times the size of the original that couldn't be played. Credit where due: the company replied and offered a refund, which is better behavior than most of the industry.
However, the shape of the complaint is enlightening. When conversion happens on someone else's metered equipment, a bad job doesn't merely waste your time. It wastes the thing you purchased.
The architectural alternative
FormatFusion doesn't meter conversions because there is nothing to meter. The conversion engines operate in your browser, on your computer, compiled into WebAssembly. Your files never upload, there is no queue to prioritize, and whether it's a long video or a small PNG, it costs us the same: nothing.
The practical comparison for everyday conversions:
| CloudConvert free | FormatFusion free | |
|---|---|---|
| Daily allowance | 10 credits, 5-min cap per job | no meter |
| File size | 1 GB | 1 GB |
| Where files go | their servers, deleted within 24 h | never leave your device |
| Queue | low priority | none, starts instantly |
| Long video | can exceed free caps | fine, up to the size cap |
FormatFusion Pro is the part we charge for: $29 once and for all, which removes the ads, raises the size limit to the maximum your device allows, enables unlimited batches with one-click ZIP download, and includes quality and bitrate controls. There is no monthly reset and nothing expires.
Honest routing
Choose CloudConvert if you need an API for automated pipelines, formats outside the mainstream, server-grade speed on very large or very long jobs, or processing your own hardware can't handle. The credit system is fair for that work, and their engineering merits its reputation.
Choose FormatFusion if the files are the standard kind (images, audio, video clips, documents, spreadsheets) and you'd prefer they never leave your machine, metered by nothing, with the whole free tier stated in a single sentence: 1 GB per file, three per batch, no daily limit, no account required.
Everyday conversion stopped needing a server years ago. Paying by the minute for it is a habit, not a necessity.
