What is PDF Compressor?

ToolLove's PDF Compressor reduces the file size of your PDF documents without compromising quality. Whether you're sending a report over email, uploading documents to a portal with file size limits, or simply saving storage space — our tool uses advanced WebAssembly and local browser technology to intelligently shrink your file without it ever leaving your device.

Unlike simple online tools, we offer three compression levels — Low, Medium, and High — so you have full control. Image-heavy PDFs can shrink by up to 70%, while text-only PDFs are optimized by stripping metadata and unused streams.

Supported use cases: Compressing scanned documents, reducing email attachment size, optimizing PDFs for web upload, submitting college assignments within file limits.
