For security reasons, file sizes for attachments are limited in free email services. For example, the maximum Gmail attachment size is 25 MB, while Outlook’s maximum file size caps at 20 MB. The limitation is intended to prevent spam and bots from overloading email servers with masses of file attachments. If you still want to send large attachments for free, you can reduce the file size, for example, by creating a zip file.
In the case of very large or many files, it’s advisable to use alternatives such as cloud providers and file hosts. The most common providers are free of charge. Nevertheless, a comparison of cloud storage services is worth checking out before you decide on a provider. Your files are stored with file hosts on the provider’s cloud server and a download link is sent to selected recipients.
Below, we present the most popular and free providers with and without sign up.
