The Need to Reduce the File Size of a PDF
PDF or Portable Document Format has given us the freedom to create and transfer files between users without having to worry about compatibility issues. We take great pains to create documents and presentations with graphics and interactive forms. The images, fonts, and styles that we use, audios and videos included, all add to file size. Large files are a problem to upload and download. To make it convenient to share we need to reduce the file size of a PDF. There are certain precautions we can take to reduce PDF file size. Image resolution, embedded fonts, and image type are the main factors that affect the size of a PDF.
Methods to Reduce the File Size of a PDF
To reduce the file size of a PDF it is necessary to edit the images, crop them, and adjust the quality. You can use an image editor to do that which allows you to crop images. Use the `Save As' command when you make changes to a PDF in any PDF authoring software. This overwrites the entire file and reduces file size considerably. Use vector-based graphics as they occupy less space and scale perfectly. GIF files are much larger and are more difficult to handle. Bitmaps, if unavoidable, should be resized and prepared for maximum compression.
Use a PDF Compressor to Reduce the File Size of a PDF
The other option to reduce the file size of a PDF is a PDF compressor. These utility programs can compress PDFs to less than half their original size. Using a PDF compressor will help you save a lot of time and the hassle of constantly worrying about file size when you create a document. You will find a host of PDF compressors online. Some developers offer free trials, after which you can purchase a full blown version. There are also freeware programs that are downloadable, while some offer online services. Go through a few buyers guides and read the reviews and ratings of a few of the top PDF compressors. Evaluate a few by testing them with your documents before you purchase one.
