Merge PDF

Combine multiple PDF files into one document in the exact order you choose while preserving each page's original size and orientation.

Original pages preservedEach imported page keeps its source dimensions and portrait or landscape orientation.
No raster conversionPages are imported directly into the new PDF instead of being turned into images.
Protected downloadThe merged file uses the same private retention and download controls as other processed files.

Choose the exact order

Arrange your PDFs before processing and the merged document follows that order exactly.

Mixed page sizes

Combine portrait, landscape and differently sized PDF pages without forcing them onto one standard page size.

Pure PHP processing

The merge engine uses FPDI with FPDF, avoiding Ghostscript-dependent rasterization for this workflow.

PDF compatibility

ConvertThings imports the original PDF pages directly so their page sizes and orientation are preserved without rasterizing them. Password-protected, encrypted or otherwise unsupported PDFs cannot be merged in this version.

Split PDF / Extract Pages Extract selected pages or page ranges from a PDF into one combined PDF or separate PDFs in a ZIP. Organize PDF Reorder, rotate and remove individual PDF pages, then export a new document while preserving original page content and geometry. Images to PDF Combine JPG, JPEG, PNG and WebP images into one PDF with custom ordering, page size, orientation and margins.
