How to use PDF tools on The Bulk Toolkit

Merge, split, compress, convert, watermark, rotate, extract, protect, and unlock PDFs — registered accounts, server processing, and plan limits explained.

Overview

Unlike image resize or compress, **PDF tools run on our servers**. You upload files, we process them, and you download the result. A **free registered account with verified email** is required — guest sessions cannot use PDF tools.

Browse everything from the PDF Tools hub or the **PDF Tools** menu in the site header.

Plan limits

  • **Files per job:** 20 (Free) · 50 (Premium) — merge and JPG→PDF accept multiple files; most other tools use one PDF at a time
  • **Max file size:** 25 MB (Free) · 50 MB (Premium) per file
  • **Daily PDF jobs:** 10 (Free) · 100 (Premium)
  • **Downloads:** Free users should download once — the job is removed after the first download. Premium keeps results for **7 days**.

All PDF tools

Typical workflow

  1. **Sign in** or create a free account, then **verify your email**.
  2. Open the tool you need from PDF Tools.
  3. **Drop PDFs** (or JPGs for JPG→PDF) onto the drop zone — thumbnails show what you selected; use **Add** to append more files up to your batch limit.
  4. Set any **tool options** (rotation angle, watermark text, page range, password, etc.).
  5. Click the action button — the page **uploads**, **polls job status**, then shows **Download** when ready.

When to use PDF vs image tools

  • **Catalog photos, marketplace listings** → Image Tools (browser-side, no account required)
  • **Invoices, contracts, scanned documents, vendor PDFs** → PDF tools (server-side, account required)
  • **Product photos needing transparency** → Background Removal

Server requirements (for admins)

Best results on the VPS use system tools: **Ghostscript** (compress), **poppler-utils** (PDF→JPG, page counts), and **qpdf** (protect/unlock). Core merge, split, rotate, watermark, and extract work with **pdf-lib** alone.
