Merge PDFs: Combine and Split

Bring your documents together with Merge PDFs, a local PDF utility for iPhone and iPad. Choose PDFs, images, supported documents, or a folder from Files. Merge everything into one PDF, create a PDF for each immediate subfolder, or split outputs by approximate size, source file count, or page count. Converted documents may have simpler formatting than the originals; preview the result before sharing. Save PDFs in the app folder, alongside the source folder, or in another folder you choose. Preview completed PDFs and share them with the system share sheet. Common merge settings are remembered for your next job. The interface adapts to iPhone Duo's inner and outer displays and to resizable iPad windows. Requires iOS 26 or iPadOS 26 or later. Document processing stays on your device. No account, upload, analytics, advertising, or tracking is required. All merge features are free; optional one-time tips support development.
