Want to Reduce PDF Size? Tried JsPDF to TCPDF? Here’s the Ultimate Solution!

Posted on

If you’re tired of struggling with oversized PDF files, you’re in the right place! In this article, we’ll explore the fascinating world of PDF size reduction, and how you can use two popular libraries – JsPDF and TCPDF – to shrink your PDFs down to size.

The Problem: Oversized PDFs

We’ve all been there – you create a beautiful PDF report, only to realize it’s too large to email or upload to your website. Oversized PDFs can be a real pain, causing frustration and wasted time. But fear not, dear reader! We’re about to dive into the world of PDF size reduction, and explore two fantastic libraries that can help you achieve your goals.

What Causes Oversized PDFs?

Before we dive into the solution, let’s quickly explore what causes oversized PDFs in the first place. Some common culprits include:

  • High-resolution images: Those beautiful images you added to your PDF report can quickly balloon the file size.
  • Fonts and typography: Using too many fonts, or fonts with large file sizes, can contribute to oversized PDFs.
  • Vector graphics: Those lovely graphs and charts you created can also add to the file size.
  • Metadata and annotations: Adding too much metadata or annotations to your PDF can also increase the file size.

Enter JsPDF and TCPDF

JsPDF and TCPDF are two popular libraries used to create and manipulate PDFs. While they share some similarities, they have different strengths and weaknesses. Let’s take a closer look at each library and how they can help you reduce PDF size.

JsPDF: The JavaScript PDF Library

JsPDF is a lightweight JavaScript library that allows you to create PDFs on the client-side. It’s perfect for web applications, and is widely used in web development. With JsPDF, you can create PDFs from scratch, or manipulate existing ones.


// Create a new PDF using JsPDF
var pdf = new jsPDF();

// Add some text to the PDF
pdf.text(10, 10, 'Hello, world!');

// Save the PDF to a file
pdf.save('example.pdf');

TCPDF: The PHP PDF Library

TCPDF is a PHP library used to create PDFs on the server-side. It’s perfect for web applications that require more complex PDF generation, such as invoices or reports. With TCPDF, you can create PDFs from scratch, or manipulate existing ones.


// Create a new PDF using TCPDF
$pdf = new TCPDF();

// Add some text to the PDF
$pdf->Cell(0, 10, 'Hello, world!', 0, 1, 'L', true, '', 0, false, 'T', 'C');

// Save the PDF to a file
$pdf->Output('example.pdf', 'F');

Reducing PDF Size with JsPDF and TCPDF

Now that we’ve introduced JsPDF and TCPDF, let’s explore how you can use these libraries to reduce PDF size. We’ll cover some general tips and techniques, as well as some specific tricks for each library.

General Tips and Techniques

Before we dive into library-specific tips, here are some general techniques you can use to reduce PDF size:

  • Optimize images: Use image compression tools like ImageOptim or TinyPNG to reduce the file size of your images.
  • Use font subsets: Instead of embedding the entire font, use font subsets to reduce the file size.
  • Remove unnecessary data: Remove any unnecessary data, such as metadata or annotations, to reduce the file size.

JsPDF-Specific Tips

Here are some JsPDF-specific tips to help you reduce PDF size:

  • Use the `compress` option: When creating a new PDF, use the `compress` option to enable compression.
  • Set the `unit` option to `pt`: Setting the `unit` option to `pt` can help reduce the file size.
  • Use the `addFont` method wisely: When adding fonts to your PDF, use the `addFont` method wisely to avoid embedding unnecessary font data.

// Create a new PDF using JsPDF, with compression enabled
var pdf = new jsPDF({
  compress: true,
  unit: 'pt'
});

// Add some text to the PDF
pdf.text(10, 10, 'Hello, world!');

// Save the PDF to a file
pdf.save('example.pdf');

TCPDF-Specific Tips

Here are some TCPDF-specific tips to help you reduce PDF size:

  • Use the `SetFont` method wisely: When setting the font, use the `SetFont` method wisely to avoid embedding unnecessary font data.
  • Use the `Image` method with `compress` enabled: When adding images to your PDF, use the `Image` method with `compress` enabled to reduce the file size.
  • Set the `PDFVersion` to `1.7`: Setting the `PDFVersion` to `1.7` can help reduce the file size.

// Create a new PDF using TCPDF, with PDF version set to 1.7
$pdf = new TCPDF('P', 'pt', 'A4', true, 'UTF-8', false, true, 'TCPDF', true, false, '1.7');

// Add some text to the PDF
$pdf->SetFont('helvetica', '', 12);
$pdf->Cell(0, 10, 'Hello, world!', 0, 1, 'L', true, '', 0, false, 'T', 'C');

// Add an image to the PDF, with compression enabled
$pdf->Image('image.jpg', 10, 10, 50, 50, 'JPG', '', '', true, 50);

// Save the PDF to a file
$pdf->Output('example.pdf', 'F');
