How to use

1

Add your files — drag and drop files onto the upload area, or click it to browse. You can add multiple files at once. Duplicates are ignored.

2

Reorder if needed — when multiple files are added, drag the handle to set the page order. This only matters for the Merge option.

3

Choose output optionsMerge into one PDF combines everything into a single document. Separate PDFs keeps each file as its own PDF, bundled into a ZIP. Choose Landscape for wide content like spreadsheets or logs.

4

Click Convert to PDF — the progress bar tracks the upload; the shimmer animation means the server is converting. Your file downloads automatically when done.
