PDF Compressor: Sign & Merge
Reduce File Size, Batch Export
Free · In‑App Purchases
Shrink any PDF on your iPhone. Compress one file or up to 50 at once, choose how small, and keep every document on device. No uploads, no account.
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.

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.
