PDFKompress

PDFKompress helps you prepare documents and images for sharing, with all file processing performed locally on your iPhone or iPad. COMPRESS - Process PDFs, JPEG, PNG, HEIC and HEIF images in mixed batches. - Choose a quality profile and, for PDFs, an optional size target. - Preview one PDF page before processing to check readability. - Save image results to Photos, with a visible confirmation, or share copies through the system share sheet. REMOVE METADATA - Use a separate mode to remove supported metadata from images and compatible PDFs without intentionally reducing quality. - Review per-file metadata categories and safety information. - Originals remain untouched. Unsupported PDF structures are skipped rather than rewritten unsafely. - Image validation supports up to 24 megapixels and 16,384 pixels per dimension. Built-in Help, iPad keyboard shortcuts and six interface languages are included. Import from Files, Photos or another app's share sheet. PDFKompress is free, without advertising, an account or a subscription. Optional tips support development and never unlock features. File processing works offline; optional tips use Apple's StoreKit service. Compression can reduce readability. A requested PDF size is not always achievable safely. Modifying a digitally signed PDF changes its cryptographic validity: always retain the original for verification.
