Read full description

Convert images, PDFs, audio, and video on your iPhone and iPad. Convert Studio X identifies each file by its actual type and shows only conversions your device can perform. Everything is processed locally—no account and no cloud upload. Import from Photos or Files, adjust the settings you need, then save verified new files to Photos or Files or send them through the system share sheet. === Features === Image Conversion Batch-convert common image formats, with additional formats offered according to the actual capabilities of your device. Resize images, adjust quality, manage transparent backgrounds, and choose to keep all metadata, remove location information, or remove all metadata. PDF Tools Export PDF pages as PNG or JPEG, or combine images and PDFs into a new document in your chosen order. Reorder, rotate, remove, split, and extract pages. You can also create password-protected copies or unlock PDFs you are authorized to process. Audio Conversion Convert common audio formats including MP3, M4A, WAV, and FLAC. Adjust quality, sample rate, and channels when available. The app shows only output options that have been verified on your current device. Video Conversion and Audio Extraction Convert between MP4 and MOV, choose H.264 or HEVC, and select source, 4K, 1080p, 720p, or 480p resolution when applicable. Balance file size and quality with simple presets, and keep the audio or create a silent copy. You can also extract M4A, MP3, WAV, or FLAC audio from video and select a readable audio track when a single video contains more than one. Batch Processing by Category Add multiple files of the same category, apply shared settings, and convert them in order. Follow the progress of each item and the complete batch. A problem with one file does not discard results that have already completed successfully. Local Conversion History Successful results stay in the app's local conversion history until you delete them. Preview results at any time, save them again to Photos when applicable or to Files, share them through the system share sheet, or delete individual results, batches, or all history. Safe Results Convert Studio X never overwrites, modifies, or deletes your original files. Every result is created in the app's own temporary location and reopened for verification before it is made available to save or share. === Designed for iPhone and iPad === • Clear, focused navigation on iPhone for one workflow at a time. • An adaptive split layout on iPad with support for portrait, landscape, and multitasking. • Support for Dark Mode, Dynamic Type, VoiceOver, increased contrast, and Reduce Motion. • Switch the app instantly between System, English, or Simplified Chinese and choose System, Light, or Dark appearance. === Privacy === File conversion takes place entirely on your device. Convert Studio X requires no account, contains no advertising, uses no analytics or telemetry, and has no hidden upload path. The app accesses photos and files only after you choose content or save a result. Diagnostic information does not include file contents, file names, full file paths, passwords, or access credentials. === Platform === Requires iOS 18 or iPadOS 18 or later.
