Drag, Drop, Done: A No-Nonsense Image Converter for Windows (with Real SVG & Multi-Size ICO Support)
Tired of uploading screenshots to sketchy online converters just to turn a PNG into a WEBP? Tired of SVG files that nothing on Windows can open? Tired of icon files that look fine on the desktop but pixelated in the taskbar? Image Converter is a tiny Windows tool that fixes all three — and it works the way you’d expect: drop a file, get a converted file in the same folder.
What it does
One small window. One dropdown. One drop area. Pick the format you want, drop your files, and the converted versions appear next to the originals. That’s the whole user interface.
Behind that simple front end is a smart pipeline that picks the right engine for the job — FFmpeg for the common formats, the Microsoft Edge rendering engine (WebView2) for tricky SVGs, and the native Windows graphics engine (GDI+) for everything in between. You don’t have to know which one is doing the work. It just converts.
13 formats, both directions
Image Converter reads and writes every one of these:
| Format | Why you’d use it |
|---|---|
| PNG | Lossless graphics, screenshots, transparency |
| JPG / JPEG | Photos — smaller files than PNG |
| WEBP | Modern web format, smaller than JPG/PNG |
| AVIF | Newest web format, smallest files |
| SVG | Vector graphics that stay sharp at any size |
| ICO | Windows shortcut and application icons |
| GIF, BMP, TIFF, PBM, PGM, PPM | Legacy and specialty workflows |
The SVG superpower
Most desktop image tools simply cannot read SVG. Even the ones that claim to often choke on the modern features designers actually use. Image Converter takes a different approach: it tries three rendering engines in order, automatically falling back if one fails.
- GDI+ — fast, handles simple SVGs.
- WebView2 — opens the SVG inside a hidden Microsoft Edge window and screenshots it. This is the same engine that renders SVGs in your browser, so anything that works on a webpage will convert here.
- FFmpeg — a final fallback for unusual cases.
The status bar at the bottom of the window tells you which engine handled the job, so you always know what’s going on.
ICO files, done properly
Here’s a thing most people don’t know: a real Windows icon is actually four images bundled together — one each for 256×256, 48×48, 32×32, and 16×16. Windows picks the right one depending on whether the icon is on your desktop, in the title bar, or in the alt-tab switcher. Convert your image to ICO with a typical online tool and you usually get a single-size file that looks blurry at the wrong zoom.
Image Converter does it the right way. Drop a square PNG (ideally 512×512 or larger), pick ico, and you get a proper multi-resolution Windows icon with full transparency and high-quality bicubic resizing for every size.
Batch drops
Got a folder of 50 screenshots that need to be JPG instead of PNG? Select them all in Explorer and drag them onto the window. Image Converter processes each one and tells you how many succeeded. Failed conversions are reported with the error message copied to your clipboard so you can paste it somewhere useful.
Why I built it
I kept hitting the same three friction points: needing to convert a single screenshot to WEBP for a blog post, needing to render an SVG icon down to a PNG for a thumbnail, and needing to bake a proper multi-size ICO for a desktop shortcut. Each one needed a different tool, and most of them wanted me to upload my files somewhere. This puts all three jobs into one tiny window that lives on my desktop.
What you need to run it
- Windows 10 or 11
- FFmpeg on your PATH (free, from ffmpeg.org)
- Microsoft Edge WebView2 Runtime (already on every Windows 11 machine; free for Windows 10) — only needed for SVG conversion
Pick format → drop file(s) → click Open Output Folder. That’s it. No menus, no settings, no surprises.
If you’ve been juggling three different tools for image conversion, give this one a try. It’s small, it’s fast, and it stays out of your way.
