How to prepare a PDF for email: merge, sign and size it

The cleanest emailed document is usually one PDF in the order the recipient expects. Merge the pieces, check every page, sign the finished copy only if a signature is needed, and make sure the finished file fits the recipient's attachment rule. Do not make several separate files smaller if one clear PDF will do the job.

This is a workflow guide, not a promise that every mailbox accepts the same file. The recipient's own instructions and their organisation's mail settings win over a generic number.

Gmail Help says personal Gmail accounts can send up to 25 MB of attachments in one message; work and school limits are set by the administrator. Microsoft Support lists a 25 MB file-attachment limit for Outlook.com. Those are useful reference points, not a reason to ignore a lower limit stated by a customer, portal or employer.

1. 1

   Put the pages in their final order

   Open every source PDF and decide the order before you combine them. A quotation, signed acceptance and supporting pages should read naturally from first page to last.

2. 2

   Merge the copy you will send

   Merge PDFs combines two to 30 PDFs in your browser. Each input PDF can be up to 100 MB. It copies pages into a new file, so keep the originals as your record.

3. 3

   Check the finished file once

   Open the merged PDF and check page order, totals, names, dates, page orientation and the final filename. It is much easier to correct a missing page before a customer sees it.

4. 4

   Sign the final version if that is what was requested

   Sign & Stamp PDF lets you draw or place a signature image, date or stamp without uploading the file. Finish merging and edits first. It adds an electronic signature image, not a certificate-based digital signature.

5. 5

   Reduce size only if it is needed

   Use the Target Size File Compressor when the finished PDF is above the recipient's limit. Inspect the result before sending, especially small text, stamps and scanned signatures.

If the final file is already small enough, do not compress it simply because a compressor exists. Compression can soften scanned pages and images, while a PDF that already fits gains nothing from another processing step.

• The recipient gave you a portal. Upload there instead of sending a parallel email attachment, unless they ask for both.
• The file is above the allowed size. Use the sharing method your organisation or recipient accepts. Check who can open the link before you send it.
• The document is especially sensitive. Follow the sender's security policy and the recipient's approved channel. An ordinary attachment can be forwarded, so a shared link is not automatically safer.
• The recipient needs a certificate signature. BuzPulse does not issue or manage signing certificates; use the named signing service or provider instead.

• They do not send the email. You download the finished PDF and attach it or share it through the channel you choose.
• They do not create a Google Drive or OneDrive link. Sharing permissions stay with the service you use, so check them there before you send.
• They do not make a certificate-based digital signature. Sign & Stamp PDF places an ordinary electronic signature image, stamp or date.
• They do not remove every size problem. The merger accepts up to 30 input PDFs and 100 MB per input file, while compression may not reach an unrealistic target without affecting images.
