Merging Multiple Scanned Documents into a Single PDF File

1. Navigating Single-Slot Document Portals

Many application sites only provide a single file upload slot for documents like \"Academic Certifications\" or \"Work Experience Documents\". If you have scanned your pages separately as individual JPEGs or single-page PDFs, you must merge them into a single file to submit them successfully.

1.1 Arranging Pages Chronologically

Page order is important for reviewers. Academic records should flow logically, like Year 1, Year 2, then Year 3. Out-of-order pages delay the verification process.

1.1.1 Orientation Alignment Rules

Keep page orientation consistent (all portrait or all landscape). Do not make reviewers rotate their monitors to read sideways pages.

2. Secure Local PDF Merging

Our PDF Merge tool operates entirely locally in your browser memory using Javascript's pdf-lib library. Your documents never upload to external servers, protecting your private files.

2.1 Resolving Dimensions and Margins

Our tool adjusts A4 and US Letter page sizes to match layout structures, keeping the combined PDF document uniform.
