ComprimirPDF

ComprimirPDF is a free browser-based PDF compression tool that reduces file size directly on your device. The document is read, compressed, and prepared for download entirely within the browser, so no bytes, content, or file names are ever sent to servers. No registration is required to use the tool. The tool solves the problem of oversized PDFs that are difficult to email, upload to forms, or store. It re-encodes images that can be safely optimised and reorganizes the document structure, while keeping text as text and preserving the number of pages. Savings depend on the content: files with many photos usually compress more than already-optimized documents. It is for anyone who needs lighter PDFs for sharing, email, forms, or screen reading, and who values privacy since processing happens locally in the browser.
