What Aconvert is
Aconvert is a free file-conversion service available on the web and through Android apps. Its online converter handles documents, ebooks, images, icons, video, audio, and archive files, and it supports converting multiple files in a batch. If a conversion fails on one server, it retries on another; it can also identify formats by examining binary signatures. Converted files can be saved to Google Drive, OneDrive, or Dropbox. The online service lists maximum uploads of 40MB for documents, ebooks, and archives, and 200MB for images, video, and audio, with some exceptions. Aconvert says transfers use HTTPS, uploaded and converted files are renamed with random 10-character filenames, and files are automatically removed after about two hours; users can delete them sooner. Site use does not require registration. The Android apps are free and ad-supported, and most can convert files offline without file-count or file-size limits. The maker says its team began developing shareware in 2000. Aconvert says it removed its REST API over potential GDPR concerns.
