How to reduce PDF size before sharing
Start with compressed images, remove unused pages, and keep scans at a practical resolution before final export.
Calculator Club PDF Tools is a fast, mobile-first toolkit for everyday document work. You can merge, split, compress, resize PDFs for Indian upload forms, export PDF pages as images, convert selectable PDF text, create image-to-PDF files, and run browser OCR for scanned documents. The key difference is privacy: supported tools handle files in your browser instead of uploading them to a server.
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.
Maximum file size is about 50MB per file, compression depends on the original PDF content, and OCR works best with clear English scans in modern browsers.

JPG is useful for previews and image uploads, while PDF is better for multi-page documents and printing.
