How to Prepare a PDF Application Pack: Order, Numbers and Watermark

Step 1: Merge in the right order

Decide the reading order before you touch any tool. A typical application pack runs: cover letter or application form first, then CV, then certificates and qualifications, then ID, then supporting letters. Merge PDF joins whole files only — it has no per-file page selection and no reorder feature — so add your files in the order you want them to read, and if you only need some pages from a file, extract those pages first with Split PDF and merge the extracted file instead. Check the merged file once, page by page, before moving on: fixing the order later means merging again.

Step 2: Number the pages

Open the merged file in the Add Page Numbers tool. Page numbers help the reader follow a long pack and refer to a specific page in correspondence. Be aware of one honest limitation: the tool stamps every page, including the cover. There is no skip-first-page option, no roman numerals, and no page X of Y format — just a plain number on every page.

The cover-page workaround

If you do not want a number on the cover, use this three-step workaround: first, split the cover page off the merged file with Split PDF; second, number the remaining pages with Add Page Numbers; third, merge the cover back in front of the numbered pages with Merge PDF. The result reads exactly as intended: an unnumbered cover followed by numbered content pages.

Step 3: Add a text watermark if needed

If the pack will be shared widely — for example a portfolio sent to several employers — a watermark marks it as yours. The Watermark PDF tool adds text only: a diagonal watermark of up to 50 characters, with three opacity levels. There is no logo or image watermark, so keep the text short, for example your name or the word Confidential. A watermark marks a document; it does not lock it. It will not stop copying, printing, or screenshots, so do not rely on it as security. PaperKit has no e-signature tool, so if a signature is required, sign the document in the application that handles signatures before merging it into the pack.

Final checks before sending

Check the file size against the email limit of the service you are sending through — Gmail 25MB, Outlook.com 25MB, Yahoo 25MB, iCloud 20MB — and compress or split the pack if it is too big; see How to Send PDF Files Anywhere: Email Limits, Sharing and Fixes for the full method. Give the file a clear name, confirm the pages are in order, and confirm the watermark text is spelled correctly. If any document is password-protected, unlock it in the application that created it first, since no PaperKit tool bypasses a password.
