PDFKompress

Compress PDFs and images, preview PDF quality and remove supported metadata on iPhone and iPad. Files stay on your device.

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.
