Merge Fillable PDFs — Without Losing Anyone's Answers

Upload your forms, get one merged PDF back. Nothing overwritten, nothing stored.

Choose files or drag and drop PDFs here

Upload one or more fillable PDF forms. Each form's fields are automatically prefixed with its filename so nothing overwrites or merges together — e.g. "Name" in form1.pdf becomes "form1_Name".

Nothing is stored

Your files are never written to a database or kept after the request finishes.

Processed and deleted

Each merge runs in its own temporary space, wiped clean the moment your download completes.

No account needed

No sign-up, no email, no tracking your identity across visits. Just upload and go.

Why forms need this

When two PDF forms both have a box called "Name," combining them the normal way makes both boxes act as one — type in one copy, and the other one changes too, or gets wiped. This tool renames each form's boxes first, so every answer stays exactly where it belongs.

Name Form A Name Form B Name !
Merging the normal way
Same box name on both forms → they become one shared box. Data overwrites or disappears.
Name Form A Name Form B A_Name B_Name ✓
With this tool
Each form's boxes get renamed first → "A_Name" and "B_Name" stay separate. Nothing overwrites.
