How It Works Under the Hood

Uses pdf-lib copyPages() directly in browser JavaScript to copy raw PDF page objects, fonts, and vector graphics between documents without re-rasterizing or sending bytes to any server.

Step-by-Step Instructions

1

Choose "Merge PDFs" to combine files or "Split / Extract Pages" to extract pages.

2

For merging, add 2 or more unencrypted PDFs and use Up/Down arrows to set order.

3

For splitting, enter page ranges such as "1-3, 5, 8-10" or split every page into a ZIP.

4

Click Merge or Extract to save your lossless PDF immediately.

Key Features & Performance

  • True Vector Copy: Preserves crisp fonts, searchable text, and hyperlinks
  • Flexible Range Parser: Supports ranges and individual pages like "1-3, 5, 7-9"
  • Burst All Pages to ZIP: Split multi-page packets into separate files in one click
  • Zero Cloud Queues: Instant client-side execution with no daily file caps

Local Browser Processing & Privacy

Traditional web converters upload your documents, snippets, or media files to remote servers. Merge & Split PDF (Vector Lossless) runs inside your browser tab:

Processed in This Tab

Your input text and files are processed locally without uploading payloads to a processing server.

No Tool Payload Logging

Microdeck does not log or store the files or inputs you paste into tool workspaces (normal static hosting/CDN requests still load page assets).

Tab Memory Lifecycle

Working outputs stay in your browser tab and are released when you reset the tool or close the tab.

Frequently Asked Questions

What if one of my PDFs is password-protected?

Encrypted PDFs cannot be merged directly while locked. Unlock the PDF first using our Unlock PDF tool, then merge the unlocked output.

Does merging reduce text crispness or image resolution?

No. Pages are copied structurally via pdf-lib without re-encoding or compressing your original PDF contents.
