QConvert is a Windows desktop tool for fast image conversion and editing directly from Explorer. It adds configurable per-user context menu actions for converting formats, resizing, cropping, compressing JPG files, optimizing PNG files, removing metadata, creating favicon bundles, exporting square avatars, and saving clipboard images as JPG or PNG. QConvert keeps the original files untouched and writes converted copies next to the source.
README
QConvert
Fast image conversion and resizing straight from the Windows Explorer context menu, by Code-iX.
Right-click an image, open the QConvert submenu, pick an action — a converted copy appears next to the original. No window, no wait.
Features
Convert: PNG, JPG/JPEG, WebP, AVIF, and ICO to supported output formats
Resize to fit: scales down (never up) to fit inside a box, keeping the aspect ratio
Crop to size: scales (up or down) to cover an exact size, then center-crops — the result is exactly that size (e.g. 1920×1080)
Crop to aspect ratio: center-crops to a ratio like 4:3 without any resizing
Cleanup and export tools: remove metadata, compress JPG, optimize PNG, create favicon bundles, create square avatars, and paste clipboard images as PNG/JPG
Converted copies keep the original name; if it already exists, a numeric suffix is inserted before the extension (photo.jpg → photo.001.jpg, …). Size operations include the output dimensions in the name (photo.1920x1080.jpg)
The original file is never touched
Transparent pixels are flattened onto white when writing JPG (instead of turning black)
Common EXIF orientations are baked in so phone photos stay upright
Per-user settings: JPEG quality plus the resize/crop entries shown in the menu
No admin rights required: installs and registers per user
Installation
winget
winget install Code-iX.QConvert
Manual
Download the MSI from the latest release and run it. The MSI is self-contained; no separate .NET Desktop Runtime install is required. The Explorer context menu is off by default and can be enabled from QConvert settings.
> WebP/AVIF note: opening these formats depends on Windows image codec support. WebP output and AVIF output are written through bundled SkiaSharp support.
> Windows 11 note: the QConvert menu appears in the classic context menu, under Show more options (Shift+F10).
Usage
Context menu
Right-click a .png, .jpg, .jpeg, or .webp file and open QConvert:
QConvert.Cli.exe is a silent Windows executable, so Explorer context-menu actions do not flash a console window. QConvert.exe remains the graphical settings and image-editor app.
The release workflow builds/tests, publishes self-contained win-x64, builds QConvert-1.2.3-x64.msi, creates a GitHub Release, and runs winget-releaser when WINGET_TOKEN is configured.
Keep the installer UpgradeCode stable across releases.
The winget identifier is Code-iX.QConvert; the installer is self-contained and should not declare a .NET runtime dependency.
First winget listing still requires the package to exist in microsoft/winget-pkgs; after that, winget-releaser can submit update PRs.
