PDF to Image
This lesson is part of Web Developer Tools · All levels
Summary
PDF to image converts each page of PDF into an image file like PNG or JPEG. This process is called rasterization: the page that originally contained text and vectors is converted into a set of pixels. The output resolution is measured in DPI; higher values result in sharper images but larger files. The results are useful for previews, presentations, or uploads that only accept images.
Key points
- Rather, it can convert a PDF page into an image pixel.
- DPI sets the level of detail: 150 for the screen, 300 for printing
- PNG is suitable for text and sharp lines, JPEG is smaller for photos
- A multi-page document usually produces many files or ZIPs
- Text on the image can no longer be selected or searched
