Compress PDF Without Uploading — No Size Limit
PDF compression tools that require a server upload expose your documents to third-party storage. This compressor works entirely inside your browser using pdf-lib to strip unnecessary metadata and compress internal structures. The result is a smaller file that never left your device.
🔒
PDF compression runs locally in your browser — your document is never sent to any server.
