How to Email PDF Directly
Sharing a PDF via email often involves a frustrating cycle: download the file, open your email client, compose a message, attach the file, and wait for it to upload. When you're working with PDFs in a browser tool, the ability to email the document directly from the workflow eliminates those steps and gets the file to the recipient faster. SublimePDF includes a direct email feature that sends your processed PDF without leaving the tool.
Follow the step-by-step instructions below, then use the free tool directly — no registration or download required.

Process your PDF
Complete any editing, merging, compressing, or converting task in SublimePDF. Once your document is ready for sharing, click the 'Email' button in the download area instead of the standard download.
Enter recipient details
Type the recipient's email address (or multiple addresses separated by commas). Add CC and BCC recipients if needed. The sender address is your own email, entered during setup.
Compose the message
Add a subject line and a brief message body. The PDF is attached automatically. Use a clear subject that describes the attachment — 'Signed Contract - Project Alpha' is far better than 'PDF Attached.'
Review attachment size
The tool shows the attachment size. If it exceeds 25 MB (common email limit), you'll be prompted to compress the file first. Click 'Compress and Send' to reduce the file before emailing.
Send and confirm
Click 'Send' to deliver the email with the PDF attached. A confirmation message shows the delivery status. The email arrives from your email address, not from SublimePDF, so recipients recognize the sender.
Pro Tips
- 💡 Always compress PDFs before emailing if they're over 10 MB. Many corporate email servers reject attachments above 10 MB even though consumer email supports up to 25 MB.
- 💡 Use the subject line to describe the document specifically — recipients receive dozens of emails with 'PDF attached' and yours will get lost without a descriptive subject.
- 💡 For sensitive documents, consider password-protecting the PDF before emailing and sharing the password through a separate channel (text message, phone call).
- 💡 Save the recipient email address in your browser's autofill for repeated sends — this speeds up future workflows when you regularly email PDFs to the same people.
Privacy & Security
All processing happens directly in your browser. Your files are never uploaded to any server — they remain on your device throughout the entire process. SublimePDF uses WebAssembly technology for fast, secure, client-side processing.
Works Everywhere
This tool works on any modern browser — Chrome, Firefox, Safari, or Edge — on desktop, tablet, or mobile. No software to install. PDF is an open ISO standard supported by all major platforms.
