Offline File Converter for Windows
Just Converter
Convert video, audio, images, HEIC files, and PDFs locally through a focused Windows desktop workflow.
Quick answer
What is Just Converter best for?
Just Converter is a free Windows file converter for people who want to process video, audio, images, HEIC files, and PDFs without uploading source files. It runs conversion workflows locally on Windows 10 or 11, supports batch work and a Portable ZIP, and is best for private or repeated desktop conversion tasks. Conversion speed for large files still depends on the local PC.
What's new in Just Converter 1.1.3
What's New in Just Converter 1.1.3
Just Converter 1.1.3 focuses on conversion reliability and interface polish. It fixes TS video conversion issues, makes video format selection more stable, improves multi-file previews, refreshes progress indicators, and sharpens the app experience across light and dark themes.
TS Video Conversion Fix
TS video files now convert more reliably. Extra data and subtitle streams that do not match the target format are handled so they do not break the conversion job.
Stable Format Selection
Video format choices now respond more consistently with a single click and no longer unexpectedly jump back to the previous format.
Cleaner Multi-file Preview
When multiple files are selected, the preview area now shows up to the first five files for a clearer and more useful overview.
Modern Progress Display
Conversion progress bars are now more readable, cleaner, and more polished during active conversion jobs.
Light and Dark Theme Polish
Button text, hover states, support popups, and language menu behavior were improved for better readability in both light and dark themes.
Store Support and Sharper Branding
Store/MSIX users now see a Microsoft Store rating support area, localized rating text fits better, and app logo rendering looks smoother.
