Ever Built a Beautiful Page in Tailwind or BootstrapThen Had No Easy Way to Export It?

Same here.

How to Use an API to Convert HTML Pages with Tailwind and Bootstrap Frameworks to PDF

I still remember the day I was finalising a client's report dashboard. It looked perfect in the browsercustom charts, Tailwind utility classes, responsive layout with Bootstrap grids, the works.

Then came the ask:

"Can we also get this in a nicely formatted PDF?"

Cue the pain.

Screenshots? Ugly.

Manual PDF styling? Nope.

Other tools? Either too clunky, didn't render Tailwind right, or just broke halfway.

That's when I stumbled onto VeryPDF Webpage to PDF Converter API.

Game-changer.

What This API Actually Does (and Why It's Worth Your Attention)

This isn't just another HTML-to-PDF service.

VeryPDF's Webpage to PDF Converter API is a dev-first, dead-simple RESTful API that turns any webpage or raw HTMLincluding Tailwind, Bootstrap, JS charts, and even mapsinto high-fidelity PDF documents.

No browser hacks.

No CSS weirdness.

No wasting time tweaking font sizes that look perfect in Chrome but break in the output.

If you're a developer or a product team that builds dynamic UIs and needs to export those views into PDFsfor reports, client handovers, legal docs, invoices, or just internal snapshotsthis is your tool.

Why I Gave VeryPDF a Shot

Honestly? I was tired of trying tools that:

  • Didn't support modern CSS frameworks like Tailwind CSS or Bootstrap 5

  • Stripped out JavaScript, killing interactivity or charts

  • Made it impossible to add headers/footers or control margins

  • Didn't scalecouldn't handle 50+ pages at once

VeryPDF ticked all the boxes.

Here's what made it click for me:

  • Advanced Chrome-based rendering engine so it actually understands Tailwind, Bootstrap, and even Web Fonts

  • Works with dynamic content wait for the page to finish loading JS? Check.

  • Fully customisable page size, headers, footers, orientation, you name it

I had a working integration within 15 minutes.

What Makes It So Useful for Tailwind and Bootstrap Projects?

If you're using Tailwind or Bootstrap to build web pages, reports, dashboards, or styled components, you already know the struggle.

Things look perfect in the browser.

But PDF output?

Often garbage.

Here's why VeryPDF nailed it:

1. Full CSS Support (Seriously)

Forget stripped styles.

Tailwind utility classes and Bootstrap components come through clean.

  • I had a Tailwind-styled grid layout with embedded charts and SVG icons. The PDF was pixel-perfect.

  • Tried another page with Bootstrap modals and cardsit rendered like a print-ready file.

2. JavaScript + Chart Support

I use Chart.js for visual reports.

Other tools ignore scripts. VeryPDF? Executes them.

  • The bar and line charts showed up exactly as intended.

  • Even dynamic elements (like toggles and maps) can be set to load before rendering using the waitForElement parameter.

3. API Simplicity

Here's the format:

http://online.verypdf.com/api/?apikey=YOUR_API_KEY&app=html2pdf&infile=https://example.com&outfile=example.pdf

Want A3 paper? Add --page-size=A3.

Need a header with page numbers? Done.

&--header-left=Report&--header-right=Page%20[page]/[toPage]

All of this can be chainedmeaning it's scriptable and scalable. Just what you want when exporting 300+ reports.

Real Use Cases I've Done (That Saved Me Days)

1. Exporting Weekly Tailwind-Based Client Dashboards

Clients loved our in-browser reportsuntil they wanted PDFs. Previously I screenshotted and stitched manually (yup). Now? A webhook hits the VeryPDF API every Monday at 9 AM and stores the PDFs in our S3 bucket.

2. Generating Legal Docs With Bootstrap Templates

We had to generate affidavits and NDAs with precise formatting. Bootstrap helped us build consistent templates. VeryPDF kept the PDF layout exactno weird breaks or spacing issues.

3. Mass Export of Invoices

Each invoice had custom data. The front-end used Tailwind for styling. I looped through invoice data, generated unique HTML files, and batched 200 conversions via the API. Done in under 10 minutes.

Compared to Other Tools? No Contest.

Tried a few before this. Here's the breakdown:

PDFShift Failed on Tailwind, missing styles.

wkhtmltopdf No JavaScript support, couldn't handle flex layouts.

Puppeteer Yes, it's powerful. But it's overkill for basic exports and doesn't scale easily for non-tech teams.

VeryPDF wins because:

  • It's just an APIno need to host a renderer.

  • It handles JS, CSS, dynamic assets, and third-party libraries out of the box.

  • It's reliable at scale with parallel processing and webhook callbacks.

Final ThoughtsIs It Worth It?

Look, if you're someone who:

  • Builds dynamic web UIs

  • Needs pixel-perfect PDFs of those UIs

  • Uses Tailwind, Bootstrap, JS libraries, or maps

  • Wants it automated with minimal hassle

Then yesVeryPDF Webpage to PDF Converter API is absolutely worth it.

I'd highly recommend this to anyone who deals with large volumes of HTML reports, invoices, or visual dashboards.

It saved me hours each week. It made my exports client-ready. And it's dead simple to implement.

Frequently Asked Questions

Can I convert pages with Tailwind and Bootstrap styles directly?

Yes, VeryPDF supports both frameworks. The rendering engine handles all modern CSS, so your styles come through exactly as designed.

What if I want to wait for JavaScript to load before generating the PDF?

Use the --wait-for-element or --javascript-delay parameters. This ensures JS-driven elements render properly.

Can I convert pages in bulk?

Absolutely. Use batch processing and webhook callbacks to handle hundreds or even thousands of conversions in parallel.

Is my data stored after conversion?

By default, no. VeryPDF doesn't store your data unless you specifically request storage (e.g., to S3).

Does it work with charts, maps, and other visual libraries?

Yes. I've tested with Chart.js, Google Maps, and D3.js. Everything rendered correctly in the PDF output.
