How to reduce PDF size before sharing
Start with compressed images, remove unused pages, and keep scans at a practical resolution before final export.
PDF Tools Online
Calculator Club PDF Tools is a fast, mobile-first toolkit for everyday document work. You can merge PDF files now, and the platform is structured for split, compress, PDF to JPG, image to PDF, HTML to PDF, PDF to text, watermark, page numbers, signature, password protection, image extraction, and basic form-fill workflows. The key difference is privacy: files are handled in your browser wherever the selected tool supports local processing.
Use the upload area to add PDFs, reorder files with the list controls, then download the result. The interface is designed for phones first, with large controls, a sticky bottom action, drag-and-drop for desktop, and clear status updates. Ads are placed in reserved slots so the tool area does not jump while you work.
