That PDF is too big to email or upload? Compress PDF shrinks it down in seconds — right on your iPhone, so your documents never leave your device. No ads. No daily limits. No subscription. Pay once. • REAL SIZE REDUCTION — re-compresses the pages so scanned and image-heavy PDFs get dramatically smaller. • THREE LEVELS — Light, Recommended, or Maximum, so you control quality vs size. • NEVER BIGGER — if a PDF is already optimized, we keep your original instead of inflating it. • 100% PRIVATE — everything happens on your iPhone. Your documents are never uploaded. • NO ADS, NO SUBSCRIPTION — pay once. No "2 free per day" trap, no watermark. Pick a PDF, choose a level, share or save. Done. Best for scanned documents, contracts, and image-heavy PDFs that won't fit an upload limit.
