The Syncfusion Essential PDF is a .NET PDF library used to optimize or compress PDF documents. Reducing the PDF file size can help you optimize bandwidth cost, network transmission, and digital storage. It is especially useful in areas like archiving or long-term preservation, emailing, and using PDF documents in web-based applications.
The Syncfusion .NET PDF library will work seamlessly regardless of the document structure and content to compress PDF with just a few lines of C# code. You can resize your files according to your requirement.
PDF files may contain many images. Removing the images from a PDF file is usually not an option as they are necessary for PDFs. Downsampling the images will decrease the number of pixels and is possibly the most effective way to reduce the PDF file size. Users can control the PDF file size with respect to the quality of the image.
Font resources will also result in large file sizes. To make the PDF smaller, remove unused glyphs and unwanted font tables from the embedded font in the PDF document.
Removing or flattening annotations can help reduce your file size. Flattening will remove annotations, but preserve its values. It will only be used when no further editing is needed.
Optimizing the page content will remove unwanted commented lines, white spaces, convert end-of-line characters to spaces, and compress all uncompressed contents.
The content of a PDF file can be updated incrementally without rewriting the entire file. Changes are appended to the end of the file, leaving its original content intact. Disabling the incremental update will rewrite the entire file, which results in a smaller PDF.
Removing or flattening form fields can help reduce your file size. Flattening will remove the form fields and preserve its values. It will only be used when no further editing is needed.
Reduce the file size by removing the metadata in the PDF document.
