How do I merge PDF files online with page-level control?

Upload single files, multiple PDFs, or an entire folder. ToolCrate renders each page visually as an interactive thumbnail. You can drag pages to reorder, rotate individual pages by 90 degrees, delete unnecessary pages, and preview the final document before downloading.

Are my PDF files uploaded to any server?

No. All PDF parsing, thumbnail rendering, page manipulation, and file merging occur 100% client-side inside your browser using pdf-lib and pdf.js. Your documents never touch external servers.

Can I reorder individual pages from different PDF files?

Yes! You can drag any page from any uploaded PDF to any position in the continuous grid. You can also mix, match, duplicate, or delete pages before producing your final combined PDF.

Is there a limit on the number of PDFs or file size?

There are no arbitrary file or page limits. The only constraint is your computer's memory.

Frequently Asked Questions

Are my PDF documents uploaded to a server?

Never. The entire workflow — parsing, rendering thumbnails, reordering pages, rotating, and generating the final PDF — runs 100% client-side inside your browser using the open-source pdf-lib and pdf.js engines. No telemetry or file uploads occur.

Can I combine pages from different PDF files in any order?

Yes. Once you add multiple PDFs, all pages appear together in a single draggable grid. You can move any page from document A ahead of or between pages of document B seamlessly.

Can I upload a folder containing multiple PDFs?

Yes. Use the "Select Folder" button or drag a folder directly onto the drop area. ToolCrate scans and imports all valid PDF documents found inside.

Is there a limit on file size or number of pages?

There are no artificial software limits, paywalls, or watermarks. The only boundary is your computer or mobile device's available browser memory.
