Can I merge PDF documents with different page sizes?

Yes. PdfShilp preserves each page’s original MediaBox and dimensions, allowing you to combine Letter, A4, and custom-sized sheets in a single file.

Can I delete specific pages before merging?

Yes. Select any page in the visual thumbnail bar and click delete to remove it from the final export.

Is there a file size limit when merging PDFs?

No server-side file size restrictions apply because all processing is bounded only by your computer’s local RAM.

Are my combined documents stored online?

Never. Merged documents exist only in your current browser session until you download them to your device.

Merge, Rotate & Reorganize PDF Pages Locally

Combine multiple PDF files into one clean document, rearrange page order via drag-and-drop, rotate sideways pages, and delete unwanted sheets instantly in your browser.

Instant Client-Side PDF Merging Without Upload Delays

Merging large multi-megabyte PDF files on traditional cloud sites is slow and frustrating: you wait minutes for uploads, server processing, and file downloads. With PdfShilp, combining documents happens in browser memory using WebAssembly. Pages are merged in milliseconds with zero bandwidth consumption and zero file size limits.

Visual Page Thumbnail Organizer

PdfShilp features an interactive visual grid displaying thumbnails of every page across all loaded documents. Drag and drop pages to reorder chapters, rotate misoriented portrait/landscape scans 90 or 180 degrees, and delete blank or redundant pages with a single click before producing your final export.

How to Merge and Reorganize Your PDFs

Step 1: Open your primary PDF document inside PdfShilp.
Step 2: Click "Add Document" to load additional PDF files to be merged.
Step 3: Reorder pages in the visual thumbnail view by dragging them into your preferred sequence.
Step 4: Rotate upside-down pages or click the trash icon to remove unnecessary sheets.
Step 5: Click "Save PDF" to download the consolidated document immediately.

Pristine Vector & Image Quality Preservation

When PdfShilp merges documents, it preserves original vector lines, embedded OpenType typography, high-resolution photographs, and color profiles without lossy recompression. Your merged document retains its original crisp printing quality.
