As answered by people managing Convertio and RunConvert.
RunConvert's answer:
RunConvert combines a huge conversion range with zero friction: Supports 1,500+ file conversions across documents, images, audio, video, e-books, archives, fonts, and more Completely free, no account or signup required - just upload, convert, download Generous 1GB upload limit, larger than most free converters Advanced Options let you fine-tune quality, resolution, bitrate, and codec settings Works in any browser on Windows, Mac, Linux, and mobile - nothing to install
RunConvert's answer:
No daily conversion caps or paywalled features that tools like Convertio or CloudConvert impose No account creation - competitors often require signup for larger files 1GB file size limit on the free tier, well above typical free-tier limits Privacy-first: 256-bit SSL encryption on all transfers, and files are auto-deleted from servers within a few hours One tool covers documents, media, archives, CAD files, and fonts, so you don't need multiple converters
RunConvert's answer:
Anyone who needs to convert files quickly without installing software or paying for a subscription - students, office workers, content creators, designers, and developers. It suits both one-off casual conversions (e.g., MOV to MP4, DOCX to PDF) and users who need finer control via advanced quality and codec settings.
RunConvert's answer:
RunConvert started with a simple frustration: converting a file online shouldn't require creating an account, hitting daily limits, or paying for a subscription just to handle a slightly larger file. Most free converters were either capped, cluttered, or pushed you toward a paywall the moment you needed something practical. We built RunConvert to remove all of that friction. The goal was one tool that handles virtually any format - documents, video, audio, images, e-books, archives - with a generous 1GB limit, no signup, and files automatically deleted within hours. What began as a straightforward converter has grown to support over 1,500 conversion types, while staying true to the original idea: upload, convert, download, done.
RunConvert's answer:
RunConvert is built on a high-performance Go (Golang) backend, chosen for its speed, concurrency, and efficiency in handling large file uploads and parallel conversions. Key parts of the stack:
Go (Golang) backend powering the API and conversion pipeline - enables fast, concurrent processing of multiple large files with a low resource footprint Industry-standard conversion engines like FFmpeg (video/audio), ImageMagick (images), and LibreOffice (documents) orchestrated by the Go services Fully browser-based frontend - works on any OS with nothing to install 256-bit SSL encryption on all transfers, with automatic file deletion within a few hours
RunConvert's answer:
RunConvert is a free tool with no account requirement, so we don't track enterprise customers. Our user base spans students, freelancers, designers, developers, and office teams worldwide who use it for everyday conversions.

Convertio has earned its reputation by handling just about any file type, not just images. If you sometimes need to switch an HEIC photo to JPG or even convert documents and audio, it’s a strong pick. - Source: dev.to / about 1 year ago

Thanks for sharing! Just to also share my method, I use https://convertio.co for conversions, and then email the books to my [email@kindle.com](mailto:email@kindle.com) account. But I'm glad to hear there's a different solution, thanks! Source: about 3 years ago
