How to optimize PDF images? Many PDF creation software and PDF editing software have a feature called PDF image optimization. This kind of image optimization may seem difficult to understand because it is set by combining several functions, the purpose of this article is to explain and provide you with methods for PDF image optimization.
What is PDF image optimization?
PDF image optimization is a function to reduce the image data size (data size) without changing the apparent size (layout size) on the page of images used in a PDF document. Many PDF software have similar functions. For example, PDFs for commercial printing use high-definition images to maintain print quality. Due to the high data volume of high-definition images, the file size of printed PDF files becomes very large, unwieldy, and inconvenient to distribute on the web. In this case, you can use the PDF image optimization feature to reduce the data size of the image, thereby making the PDF file smaller.
How to achieve image optimization?
1. When creating a new PDF file
Use an application such as Office or DTP to create documents that contain data-heavy images, then reduce the data size of the images before creating the PDF from the images before embedding them in the PDF.
For example, Antenna House PDF Driver (AH PDF Driver) is software that creates PDFs from an application’s print menu. In the settings menu of this AH PDF Driver there is a tab called “Compression”. When the “Compression” tab is selected, the following dialog box will be displayed, and the part surrounded by the red frame corresponds to the image optimization function.
2. Recompression of existing PDF files
Extracts embedded images in created PDFs, reduces image data size, and compresses back to PDF. Now there is no need to perform such complicated operations, and the two web service tools, pdf to jpg convert online and jpg to pdf convert online , can freely convert between PDF and JPG.
Conversion steps:
Step 1. Log in to “AbcdPDF Platform”.
Step 2. Select “PDF to JPG”.
Step 3. Select “Select File” and upload the file.
Step 4. Wait for the conversion to complete and click the “Convert” button at the bottom right.
Step 5. Click “Download” in the lower right corner to download the converted JPG format to the local.
Note, if the PDF file you uploaded before is composed of multiple pages, the downloaded JPG file will also have the corresponding number of pages.
Summarize
How to optimize PDF images? This article introduces the principle and operation method of PDF image optimization. For users who want to switch back and forth between PDF and JPG formats, they can use pdf to jpg convert online , jpg to pdf convert online These two online service tools are very effective in converting into pictures.
