  • iLovePDF 

iLovePDF is a flexible online tool for PDF conversion and compression, similar to Smallpdf. The program for shrinking PDF files is not entirely free to use. When utilizing the free version, the maximum size of the PDF files you may submit is 200MB, and each operation can compress no more than two files at once. You must sign up and subscribe to the premium edition, which costs $6 per month, in order to get around these restrictions. 

The compressor gives users three options once they submit PDF files: high compression, suggested compression, and reduced compression. The PDF file may be severely compressed to be as small as possible, but the quality will suffer. However, less compression can only reach an exceptionally low compression ratio while still maintaining high quality. Choose the suggested compression as a result for an improved outcome.
