The 25MB Email Attachment Limit Problem
Almost everyone has encountered the frustrating "File too large to attach" error message. Most major email providers, including Gmail, Outlook, Yahoo Mail, and ProtonMail, limit attachment sizes to 25MB per email. This limit is due to the way email protocols handle binary attachments, which are converted into text format (Base64 encoding). This conversion increases the file size by about 33%, meaning a 20MB file can require nearly 27MB of email transmission capacity.
Additionally, storing massive attachments in email inboxes is inefficient and costly for mail servers. To bypass this restriction, the standard approach is to upload your files elsewhere and insert a download link into the body of your email.
Comparison of Email Link-Sharing Methods
When sending files via an email link, you have several choices. Compare the primary options below to find the best fit for your needs:
| Method | Size Limit | Sign-Up Required? | Recipient Sign-Up? | Privacy / Storage |
|---|---|---|---|---|
| Google Drive / OneDrive Link | 15 GB (Drive) / 5 GB (OneDrive) | Yes (sender must log in) | No (if link permissions are set correctly) | Stored on cloud servers indefinitely |
| Traditional Upload Sites (e.g., WeTransfer) | 2 GB (Free tier) | No | No | Stored on third-party servers for 7 days |
| Direct P2P Link (SendFiles) | Unlimited (No size cap) | No (Anonymous) | No | Zero retention (never saved to database) |
How to Send Large Files via Email Link (Step-by-Step)
Follow these steps to send files of any size via email link:
Step 1: Choose Your Platform
Open our homepage in your web browser. No registration or signup is required.
Step 2: Add Your Large Files
Drag and drop your large files or folders (such as videos, ZIP archives, or presentations) into the transfer area. The browser will prepare them for transfer locally.
Step 3: Copy the Secure Link
Copy the generated link. This link contains the unique connection ID and the decryption key, which remains private in the URL hash.
Step 4: Paste into Your Email and Send
Open your email client (Gmail, Outlook, etc.), compose your message, paste the link, and send it to your recipient. Keep the browser tab open to allow the files to stream directly when the recipient opens the link.
The Privacy Advantages of Client-Side Encryption
When you send links using standard cloud storage providers, those providers have access to your files and can scan them for content. This is a common practice for automated moderation and analysis.
Our platform uses client-side encryption. The decryption key is generated in your browser and appended as a URL hash, which is not sent to our servers. This ensures that only you and the recipient can decrypt the files, keeping your shared data private.
Frequently Asked Questions
Can I send files larger than 10GB via email link?
Yes. Since P2P transfers stream directly between browsers and do not store files, there are no file size limits. You can send files of any size.
Does the link expire?
The transfer link remains active as long as your browser tab remains open. Once you close the tab, the connection closes and the link expires.
Do my recipients need any special software?
No. The recipient only needs to click the link in the email. The download and decryption happen entirely within their web browser.
Are my transfers secure from intercept?
Yes. The connection uses DTLS/SRTP encryption. However, since the decryption key is in the link, you should send the link via secure messaging or email.
