• Lossless compression. This function reduces the file size while maintaining the original quality of text and images. It analyzes the content and removes redundant metadata, optimizing the internal structure of the PDF.
• Image compression. Readjusts images within the document, applying advanced compression methods. Reduces resolution if necessary and converts inefficient formats like BMP to JPEG or PNG.
• Removal of hidden objects. Detects non-visible elements in the document, such as hidden layers or deleted comments, and removes them to reduce the file size.
• Batch processing. Allows loading and compressing multiple PDF files at once. The function processes each document individually and generates separate results.
• Compression level setting. Offers customizable options to adjust compression intensity. Levels range from light optimization to maximum size reduction.
• Extraction of unused fonts. Identifies embedded typefaces that are not used in the document and removes them to reduce occupied space.
• Merging PDF files. Combines multiple documents into a single file before applying compression. The function preserves page order and the structure of each PDF.
• Removal of bookmarks and links. Removes hyperlinks and bookmarks if they are not necessary, contributing to a greater reduction in final size.
• Grayscale conversion. Transforms color images to black and white to reduce file weight, especially useful for documents with many illustrations.
• Preview of changes. Shows a preview of the PDF after compression, allowing comparison between the original size and the final result before saving.

Minimal PDF Compress was created in 2022 by a team of independent developers. The program is written in Python and uses libraries such as PyPDF2 and Pillow for file processing. The project is hosted on GitHub under a license that allows its use and modification. The first stable version was published in March 2022, with later updates focused on improving compression efficiency and compatibility with complex PDF formats.
