How does WeCompress file compression work?
Large PDFs and Microsoft Office documents often contain hidden bloat that can be optimized to reduce file size. The WeCompress File Compressor applies the most effective compression technique to each component, without altering the file format or visual integrity.
Our targeted approach extends to images, where we re-encode JPEGs more efficiently, reduce the number of colors in PNGs, and apply lossless LZW compression to TIFFs.
