The Complete PDF Workflow: Create, Split, Merge, and Extract

PDFs are everywhere. Contracts, invoices, reports, presentations, manuals. And somehow, the task is never "just read this PDF." It's always "take pages 3-7 from this one, combine it with that one, and turn the whole thing into images for the slide deck."

Here's how to handle every common PDF workflow without installing desktop software.

Creating PDFs: Start from HTML

The cleanest way to generate a PDF is to start with HTML. You control the layout, the fonts, the spacing. It looks exactly how you designed it.

This is how most modern invoicing, reporting, and documentation systems work. Build it as a web page, convert to PDF.

Use cases: Monthly reports with dynamic data, invoices with calculated totals, documentation with consistent branding. If you can build it in HTML, you can make it a PDF.

Pro tip: Use print-specific CSS (@media print) to control page breaks, hide navigation elements, and adjust margins. The PDF output will respect these rules.

Splitting PDFs: Extract What You Need

A 200-page manual. You need chapter 3 (pages 45-72). Nobody needs to download the whole thing.

Or a scanned document where pages 1-2 are the cover and table of contents, and pages 3-10 are the actual content. Split out the useful part.

Common splitting scenarios:

• Chapter extraction: Pull specific page ranges from a book or manual
• Form isolation: Extract a single form from a multi-form document
• Size reduction: Break a large PDF into smaller, email-friendly chunks (under 10 MB each)
• Content separation: Split a combined scan into individual documents

Merging PDFs: Combine Into One

The opposite problem: you have five separate documents that need to become one.

Real scenarios where this comes up constantly:

• Contract packages: NDA + agreement + appendices + signature pages into one file
• Application bundles: Resume + cover letter + references + portfolio
• Report compilation: Monthly reports from different departments into a quarterly summary
• Meeting prep: Agenda + previous minutes + supporting documents

The merge order matters. Think about how someone will read through the combined document and arrange pages accordingly.

Extracting Images: PDF to Image Conversion

Sometimes you need a PDF page as an image. Presentations, social media posts, thumbnails, or embedding in a web page where you can't use a PDF viewer.

The PDF to image converter gives you PNG or JPEG versions of each page. High resolution for printing, lower resolution for web — match the output to the use case.

Common use cases:

• Presentation slides: Drop a chart or diagram from a PDF report into your slide deck
• Social media: Share a specific page or quote as an image post
• Web thumbnails: Show a preview of a downloadable document
• Archival: Convert old PDFs to image format for long-term storage systems that don't handle PDFs

Real Workflow: The Quarterly Report

Here's how these tools chain together in a real business scenario:

1. Create: Build each section's report as HTML with live data, then convert to PDF
2. Split: A team submits a combined document — extract only the relevant pages
3. Merge: Combine the executive summary, financial data, team reports, and appendices into one file
4. Extract: Convert the key charts to images for the board presentation

That's four tools, one workflow, and a process that used to take an hour with desktop software now takes ten minutes.

Real Workflow: Client Onboarding Package

Another common one:

1. Create: Generate a personalized welcome letter from an HTML template (HTML to PDF)
2. Merge: Combine the welcome letter + service agreement + privacy policy + onboarding checklist (merge)
3. Split: After the client signs and returns, extract just the signed agreement for your records
4. Extract: Convert the signature page to an image for your CRM

Tips for Better PDFs

Page size matters: A4 vs Letter seems like a small difference until your footer gets cut off. Know your audience's paper standard.

Compression counts: Scanned PDFs with images can be huge. A 50-page scanned contract might be 80 MB. That's too large for email, too slow for cloud storage.

Naming conventions: When you're merging and splitting, file names are your lifeline. Q4-2025-financial-report-final-v2-FINAL.pdf isn't a naming convention — it's a cry for help. Use dates and descriptive names.

PDFs aren't going away. Every business runs on them. The difference between a painful PDF workflow and a smooth one is having the right tools connected in the right order. Create, split, merge, extract — four operations that cover 90% of what you'll ever need to do with a PDF.
