You are optimizing metadata, stripping unnecessary fonts, and re-encoding images to ensure your document remains professional. Whether you are a student submitting a thesis or a lawyer sending court documents, our tool ensures your PDF size reduction doesn't lead to blurry text.

Lossless vs. Lossy Compression
