Reduce attachments’ size with compressing them to zipped files

Reduce attachments’ size when sending emails with Kutools for Outlook

Actually, we can compress files to zipped files beforehand, and then attach the zipped files in your email. Please do as follows:

1. In the File Explorer, open the folder containing the files you will add as attachments in your email.

2. Select these files, right click and select Send to > Compressed (zipped) folder from the context menu. See screenshot:

3. Click Home > New Email to create a new email in Outlook, and then click Insert > Attach File > Browse This PC or (Insert > Attach File).

4. In the Insert File dialog box, (1) open the folder containing the zipped file, (2) select the zipped file, (3) and click the Open or Insert button. See screenshot:

5. Compose the email and send it.

This method will introduce Kutools for Outlook’s Auto compress outgoing attachments options to automatically compress all attachments to zipped files in outgoing emails.

1. Click Kutools > Options to open the Attachment Options dialog box. See screenshot:

2. In the Attachment Options dialog box, please check the Automatically compress attachments before sending emails option on the Compress tab, and click the Ok button. See screenshot:

3. Now click Home > New Email to create a new email, and insert attachments as normal, compose the email and send it.

After sending, you will see all attachments in the sent emails have been compressed to zipped files automatically, and all attachments’ size are reduced too. See screenshot:
