ComprimirPDF is a free online tool that reduces the size of PDF files directly in the browser. The document never leaves your device; all processing happens locally. You drag or select a PDF, choose one of three compression levels (Recommended, Better quality, Maximum compression), and the tool re‑encodes images, reorganizes the structure, and creates a new file. If the result is smaller, a download link appears; if not, the original is kept. The service works without registration and accepts a single PDF up to 100 MB. Password‑protected PDFs must be unlocked first, and digital signatures may become invalid because the file is rewritten. Links, forms and text are preserved when possible, but you should verify the compressed copy before sharing, especially for PDF/A, PDF/UA or other compliance‑required documents. All operations occur in the browser, so no bytes, filenames or content are sent to external servers. The tool is intended for quick sharing, email attachments, or screen‑readable PDFs where a smaller file size is beneficial.
