Attaching documents to a message and limits

You can attach multiple files to an email in two different ways:

 

  1. When selecting the files to attach, select the first file, hold down control on your device, and select the other documents you would like to attach.

Add attachments in the composer

2. The other way is to use drag & drop from the file directory, directly in to the composer.

The size limit of the attachments it is less than 25MB (per email), and the total number of files that can be attached is 100.

    Is there any plans on enlarging the send and receive attachment size? For instance Tutamail can send and receive 25 mb attachments. I’m considering switching because of the larger files size available, but prefer Protonmail

    The attachment size has been increased to 25 MB.

    Why is it with the ios app the only attachment option is photos? There should be a way to add basic office docs.

  4. ProtonMail Support

    The option to import another files is now available on our iOS app.

    Any plans to increase the size of attachments in the future, especially for direct transfer of emails inside protonmail?

    Hi,
    We have increased the attachment limit to 25MB.

    Will there be a way on the mobile app to send attachments other than just pictures? It would be very useful to be able to access Google Drive, Dropbox, etc. and add files from these sources to a Proton mail message (from mobile).

    Thanks!

    How can I increase the font size?

  9. ProtonMail Support

    To increase the font size in the composer, click on Text options (the button with the letter A) to expand the additional text options toolbar.

    Can I send .zip files in the attachement?

  11. Proton Editor

    Yes, you can attach ZIP files to an email message, just make sure the total size of the attachments is under the 25 MB limit.

    Hi
    How can I remove and suppress a file to an email received (for example to decrease my data space) ?
    Thanks

    You cannot remove just an attachment from a received message. If you need to free up storage space, you will need to delete the whole message.

    25MB attachment is amateur. If I am using PROTON it’s because I don’t want to upload to YouTube or any other big brother machine. Let’s get it up’d or create a space where we can load it to. Thanks – keep up the good work!
