What Conversion Tools Does
Conversion Tools is a web-based file converter that handles a wide range of document, image, audio, video, and data formats, including JSON, XML, Excel, PDF, and Word. Users upload a file through the browser, choose an output format, and download the converted result without installing any software.
The platform also exposes an API so developers can trigger conversions programmatically from their own applications, which extends its use beyond one-off manual conversions into automated pipelines.
Pricing and File Size Limits
Conversion Tools uses a freemium pricing structure. The free tier supports smaller files and a limited number of monthly conversions, which suits occasional users.
Paid plans raise the file size ceiling and monthly conversion quota, with published tiers ranging from roughly 7 USD per month for 100 MB files and 200 conversions up to about 52 USD per month for 2 GB files and 1,000 conversions. A pricing update took effect in April 2026, raising list prices for new subscribers while grandfathering existing subscriptions at their original rate.
Company Transparency Caveats
Unlike many SaaS vendors, Conversion Tools does not publish a founding date, headquarters address, or team information on its site. The site's legal pages refer only to the 'ConversionTools Authors' as the operating entity.
Prospective users who need vendor accountability for compliance reasons should factor in this limited public disclosure before uploading sensitive or regulated documents.
