Convertio

Convertio is a browser-based file conversion service that lets users upload files, choose an output format and download the converted result, with processing carried out in the cloud so no software is installed locally. It supports more than 300 file formats and over 25,600 conversions between them, covering audio, video, image, document, archive, presentation, font and ebook types as well as OCR. Conversion settings such as quality, aspect ratio, codec, rotation and flip are available for many types. Uploaded files are deleted immediately after conversion and output files after 24 hours, with data isolated per conversion and communication protected by TLS.

Alongside the web interface, Convertio offers a conversion API with documentation, CLI docs and API pricing, plus a Chrome extension. The service runs in the browser across platforms and stores data in Germany under GDPR.

A free tier is available without registration, with a 1 GB maximum file size per conversion. Paid subscriptions are offered in Lite, Basic, Pro and Custom editions, billed monthly or annually, with higher file size limits, conversion credits, concurrent conversions and processing priority. Conversion credits reflect server time used, and credits are charged only for conversions that complete successfully.
