Compress PDF โ Shrink File Size, 100% On Your Device Is a PDF too large to email, upload, or submit? Compress PDF reduces file size in seconds, right on your iPhone or iPad โ without ever sending your document to a server. COMMON PROBLEMS THIS SOLVES - An application portal rejects your file for exceeding its size limit - A form, registration, or submission system caps uploads at a few MB - Your email provider blocks large attachments - A scanned document or photo-heavy PDF is taking up way too much storage - You just want a faster, lighter file to share If any of that sounds familiar, Compress PDF fixes it in a few taps. 100% OFFLINE โ NOTHING IS EVER UPLOADED Unlike most PDF compressor apps, which quietly send your files to a server to process them, Compress PDF works entirely on-device. Your contracts, IDs, scans, and personal documents never leave your phone. No account, no sign-up, no cloud dependency โ just fast, private compression, even with no internet connection. 5 COMPRESSION LEVELS โ PICK ONE, OR TAKE FULL CONTROL - High Quality โ light compression, virtually no visible quality loss - Medium โ balanced size reduction - Standard (Recommended) โ a smart default so you don't have to think about it - Low Quality โ maximum size reduction when you need the smallest file possible - Custom โ full manual control over JPEG quality, image resolution/DPI, color mode (grayscale or black & white), metadata removal, thumbnail removal, and font optimization โ with a live estimated size preview as you adjust Most competing apps give you a single "compress" button and hope for the best. Compress PDF gives you a real dial when you need one, so you can hit an exact size target for a strict upload portal instead of guessing. BATCH COMPRESS MULTIPLE PDFs AT ONCE Select several files and compress them together in a single batch job. A dedicated progress screen shows the true status of every file โ waiting, compressing, done, failed, or skipped โ instead of one vague spinner. When it's finished, Share All or Export All bundles every result into a single zip so you're not tapping through separate share sheets one file at a time. HANDLES PASSWORD-PROTECTED PDFs Locked PDF? The app detects it and asks for the password instead of silently failing partway through. A COMPLETE PDF WORKFLOW, NOT JUST A COMPRESSOR - Built-in viewer to preview any PDF before or after compressing โ vertical or book-style scrolling, pinch-to-zoom, rotate, jump-to-page, print, and share - Export or Save to any location you choose โ not locked into app-only storage - History tracks every compression with before/after size and % saved, searchable by name, with quick re-share, re-export, or delete BUILT FOR EVERYONE Available in 20 languages with full right-to-left support for Arabic and Urdu. Light, dark, and system themes, each fully designed. Set your default compression level once so returning visits don't require re-picking settings. WHO IT'S FOR - Students and professionals submitting documents with a strict size cap - Anyone emailing large scans, reports, or contracts - People freeing up storage without sacrificing document quality - Power users who want manual control over DPI, quality, and color โ not just a black-box "compress" button Compress PDF is free to use, with ads. Pro is an auto-renewable subscription (in-app purchase) that removes all ads and lifts the batch-size limit for unlimited files per batch โ support ongoing development and get early access to new features. Download Compress PDF and shrink your files in seconds โ privately, offline, and exactly the way you want. Terms of use: https://codifyappsprivacy.blogspot.com/p/terms-of-use.html
