Do you need to convert PDF files to images in Java? PDF files are not directly supported in Java but you can solve this problem very easily with a third-party Java PDF library.

This tutorial shows in simple steps Java PDF to Image conversion using our popular JPedal Java PDF library. You can convert a PDF file to a BufferedImage in Java or save it directly to BMP, GIF, HEIC, JPEG, JPEG2000, PNG, TIFF, or WebP.

How to convert PDF to image in Java (Method 1 – fast and standard quality image)

Download JPedal trial jar.
Create a File handle, InputStream or URL pointing to the PDF file
```
ConvertPagesToImages extract=new ConvertPagesToImages(path);
```
Include a password if file password protected
```
extract.setPassword("password");
```
Open the PDF file
```
if (extract.openPDFFile()) {
```

Iterate over the pages

int pageCount = extract.getPageCount();
  for (int page = 1; page <= pageCount; page++) {
      BufferedImage img = extract.getPageAsImage(page, hasAlpha);
  }
}

Close the PDF file
```
 extract.closePDFfile();
```

How to convert PDF to image in Java (Method 2 – slower and very high quality image)

Download JPedal trial jar.

Create a File handle, InputStream or URL pointing to the PDF file

ConvertPagesToHiResImages extract=
new ConvertPagesToHiResImages(path);

Include a password if file password protected
```
extract.setPassword("password");
```
Set conversion options for output defined in JPedalSettings
```
HashMap options=new HashMap();
```
Open the PDF file
```
if (extract.openPDFFile()) {
```

Iterate over the pages

int pageCount = extract.getPageCount();
  for (int page = 1; page <= pageCount; page++) {
    BufferedImage img = extract.getPageAsHiResImage(page, 
    hasAlpha, options);
  }
}

Close the PDF file
```
 extract.closePDFfile();
```
