About PDF Compressor: Sign & Merge

PDF Compressor is a practical PDF compression and document toolkit for iPhone. Reduce PDF file size for email attachments, upload limits, forms, school documents, receipts, contracts, and scanned pages. Compress a single PDF, or batch compress up to 50 PDFs in one pass. You see the estimated output size before you export and the exact amount saved after. Everything runs on your iPhone. Files are never uploaded to a server, and no account is required. Document tools are included for the rest of the job: scan paper to PDF, reorder or rotate pages, sign, watermark, merge, convert JPG and JPEG images into PDF, and export PDF pages as JPEG images. Choose the output style that fits your task. Use a smaller setting when you need the lightest file, a balanced setting for everyday sharing, or a sharper setting when page readability matters most. Use PDF Compressor to: - Compress a PDF and reduce its file size - Make a PDF smaller for email or upload limits - Batch compress up to 50 PDFs at once - Choose smaller, balanced, or sharper output - Check the size saved before you keep the result - Shrink heavy scans and image-based PDFs - Save finished files to Files - Work offline, with no upload and no account - Scan paper documents into a new PDF - Reorder, rotate, or remove PDF pages - Sign a PDF with a drawn or typed signature - Merge PDF files into one document - Add text watermarks to a new PDF copy - Combine JPEG and JPG images into a PDF - Export PDF pages as JPEG files PDF Compressor is built for documents that are too large to send, store, or submit online. Compression may render pages into image-backed PDF pages. This can make scanned or image-heavy documents much smaller, but may remove selectable text, annotations, forms, links, metadata, and layers. Always check exported files before deleting originals. Scanned PDFs are image-backed documents created from camera captures. Page editing exports a new PDF copy with reordered, rotated, or removed pages; it does not edit existing text in the original PDF. Watermarks and signatures are visual marks added to a new PDF copy on your device. They are not certificate-based digital signatures. PDF Compressor Pro PDF Compressor Pro unlocks every export tool. Choose either plan: - Lifetime Unlock: a single payment, yours forever. - Pro Monthly: an auto-renewable monthly subscription. Payment is charged to your Apple Account when you confirm the purchase. A monthly subscription renews automatically for the same period unless you cancel it at least 24 hours before the current period ends. You can manage or cancel your subscription in your Apple Account settings.
