Zamzar is one of the oldest online converters and keeps the process to three steps: pick a file, pick a format, convert. It lists more than 1,100 formats, including CAD, 3D and e-book types, and can pull files from your computer, a URL, Box, Dropbox, Google Drive or OneDrive, then email you when the job is done. Alongside conversion it compresses, splits, rotates and turns audio, video or images into text. Free converted files are kept for up to 24 hours, while paying users keep files until they delete them. The free plan's 50MB upload limit is the main weakness; CloudConvert, Convertio and FreeConvert all allow 1 GB for free. Zamzar aims to finish conversions in under 10 minutes and offers email help for files that fail. A desktop app covers Windows and Mac, and the developer API starts at $25 a month. Consumer plan prices did not load from our location, so that price is pending. We compared documented features and published prices.
