Shrinking PDF Files - Some Simple Techniques
If you're wondering `how do I shrink my PDF files to normal size', the solution is really simple and very easy to execute too. You can reduce the PDF file size by decreasing the number of fonts used in the file, reducing the resolution of the images inserted in the PDF, using smaller sized images like GIF instead of JPG and other image formats and inserting black and white images instead of colored ones. To shrink PDF file size, keep these measures in mind. Instead of going in for simple techniques like these, you can also use commercially available software that would help you to tackle the question of how to shrink PDF files to normal size.
Compression Algorithms and PDF Optimizer
Different types of compression software make use of different compression algorithms. Each compression algorithm differs by the compression ratio it provides. Some of the algorithms include FLATE, ZIP, JPG, and LZW. Some algorithms provide lossless compression while some provide lossy compression with greater compression ratio. Images added to PDF after being compressed separately, can yield a better result. Only high quality images can be used for this process so the image in the PDF will not appear blurred or distorted. PDF optimizers further help in shrinking the size of the PDF file at hand. They can recognize the objects that occupy large space and can help in removing unwanted objects.
Removing Unwanted Objects
If you are wondering how to shrink your PDF files to normal size without using compression algorithms, you can try removing the unwanted items in the file. After recognizing the unwanted objects in the PDF document with the help of a PDF optimizer, they can be removed to reduce file size. Some of the commonly found `unwanted objects' in a PDF are links, bookmarks, annotations, form fields and subset fonts. You can use a PDF-editing tool to clean up these objects and save up on memory space. Advanced tools will help you find more solutions to the issue of how you can shrink your PDF files to normal size.
