What’s new
Version 2.3.0 · Updated October 17, 2026
FormatBox v2.3 — Ready for iPhone Duo, and more reliable. • iPhone Duo: Convert, Tools, History and Settings now use the inner display properly, with two-column layouts, a tools sidebar and live previews that stay clear of the fold. • A steadier navigation bar that no longer floats over your content when you scroll back up. • Text now follows your Larger Text setting, and controls are easier to use with VoiceOver. • Fixed photos coming out sideways in SVG conversion and in Clean Metadata, rotated PDF pages being cropped, and cancelling a video compression. • Large RAR and TAR archives are now unpacked piece by piece instead of all at once, and temporary files are cleaned up after every job. • Fixed missing translations in the Font Converter and EPUB tools, and corrected a few messages in Spanish, French and Italian. No uploads. No tracking. No account required.
