How many application PDFs can I merge?

Two to ten files, with the complete upload request below 16MB.

Should I compress before or after merging?

Usually merge and inspect the final packet first, then compress only if a smaller submission is required.

Can I merge digitally signed forms?

Rewriting can invalidate signatures. Follow the recipient's rules and keep the signed originals.

PDF tools / Application packets

Build one application PDF from a checklist—not from whatever filename sorts first.

Application packets fail through missing pages, duplicate drafts, broken signatures, and the wrong order more often than through the merge itself. A numbered source checklist makes those mistakes visible before upload.

Merge PDF accepts 2–10 files, but the complete multipart request must stay below 16MB. Keep originals and inspect the exact output you will submit.

Before the upload

Prepare the document for this specific job.

Temporary PDF files are scheduled for deletion after 60 minutes, but sensitive or regulated documents should not be uploaded without appropriate authorization and controls.

01List requirements

Record every required document, page, signature, date, translation, and certification.

02Number working copies

Use names such as 01-form, 02-letter, and 03-supporting-documents to expose gaps.

03Protect signed originals

Rewriting a digitally signed PDF can invalidate it; follow the recipient's rules.

Keep the claim honest

Application Packet Merge still needs a source and output check.

What the tool is for

The tool combines page sequences into one downloadable PDF.
Moving a checked result into the next document or sharing step.

What needs your review

Forms, links, embedded files, fonts, and digital signatures can change when rewritten.
It does not know or validate the recipient's application requirements.
