Ensure you have a stable internet connection before uploading large files, and verify that the file does not contain sensitive information that requires password protection before uploading to a public cloud server.
Share via Cloud Storage Links (Google Drive, OneDrive, Dropbox)
Uploading your file to a popular cloud drive and sharing the link is the most reliable way to bypass email attachment limits.
Since most email providers limit attachments to 25 MB, you can use free cloud storage platforms to host the file and send a secure download link to your recipient.
Sign in to your preferred cloud service provider, such as Google Drive, Microsoft OneDrive, or Dropbox.
Click the 'New' or 'Upload' button and select your 42 MB file, or simply drag and drop the file into the cloud storage dashboard.
Once the upload is complete, right-click the file and select 'Share' or 'Get link'.
Adjust the sharing permissions to 'Anyone with the link can view', then copy the generated URL.
Paste the copied link into your email draft and send it to your recipient.

Frequently Asked Questions
What is the standard email attachment size limit?
Most standard email providers, such as Gmail, Yahoo, and Outlook, have a maximum attachment size limit of 20 MB to 25 MB. For anything larger, like a 42 MB file, you must use a cloud-sharing link or a file transfer service.
Can I password-protect the file before sharing it online?
Yes. Before uploading, you can use software like WPS Office or ZIP utilities to encrypt the file with a password. Alternatively, many premium cloud services allow you to set a password directly on the share link from their platform.
Do recipients need an account to download the file from a shared link?
In most cases, no. If you set the sharing permissions to 'Anyone with the link,' the recipient can simply click the link and download the file from their web browser without signing in or creating an account.
How long do shared cloud links remain active?
Links generated from standard cloud services like Google Drive or Dropbox remain active indefinitely until you delete the file or manually revoke the link. However, some dedicated file-transfer services automatically expire links after 7 to 30 days.
