What icon sizes are supported?

It extracts all standard Windows icon sizes including 16x16, 24x24, 32x32, 48x48, 64x64, 96x96, 128x128, 256x256 and 512x512 pixels, plus any non-standard sizes embedded in the source files.

Can I extract icons from Windows system DLLs?

Yes. You can extract icons from any DLL including Windows system libraries like Shell32.dll, ImageRes.dll and DDORes.dll, which hold hundreds of system icons, and export them to PNG, BMP or ICO.

Is transparency preserved when exporting icons?

Yes. Full alpha channel transparency is preserved when exporting to PNG or ICO, including semi-transparent pixels. BMP does not support transparency, so transparent areas use a solid background colour.

Can I process multiple files at once?

Yes. ICO Converter supports batch processing. Add multiple ICO, DLL or EXE files, or a whole folder, and all extracted icons are organised by source file.

What export formats are available?

Seven formats plus 2 quick copies: PNG and TIFF keep transparency, BMP, JPEG and GIF are flattened for legacy targets, ICO exports single, combined or per-file icons and CUR keeps the cursor hotspot. Any icon also copies to the clipboard or as a PNG data URI.

Does the software require an internet connection?

No. ICO Converter is a desktop application that works completely offline. Files are processed locally and never uploaded, ensuring complete privacy.

What are the limitations of the free trial?

The demo edition gives full viewing and inspection. Batch exports are limited to a fixed number of items per operation. Licensed editions remove the limit and show the edition name in the status bar.

Can it open cursor files and animated cursors?

Yes. .cur cursor files open with their hotspot read from the file. .ani animated cursors open frame by frame. Export back to CUR and the hotspot is kept. Any frame also converts to PNG or ICO.

Can I create an ICO or a favicon from a PNG or SVG?

Yes, both. Create ICO from Image turns a PNG, JPG or SVG into a multi-size Windows icon. Create Favicon Package writes favicon.ico, the standard PNG sizes, apple-touch and android-chrome icons, a site.webmanifest and a paste-ready HTML snippet from one image.

Key Features

Why use Univik ICO Converter

Extract icons from any source file with precision. Convert to multiple formats while preserving transparency and quality across all icon sizes.

Multi-Icon File Support

Open ICO files containing multiple icon images at different resolutions. The software automatically detects and displays all embedded icons, allowing you to preview each size variant and select specific icons for export or convert all at once.

DLL Icon Extraction

Extract every icon resource from DLL libraries plus OCX controls, SCR screen savers, CPL applets and DRV drivers. Perfect for accessing Windows system icons from Shell32.dll, ImageRes.dll, or extracting branded icons from third-party application libraries.

EXE Icon Extraction

Retrieve icons directly from executable files. Extract application icons, toolbar graphics and other embedded icon resources from any Windows EXE file for documentation, presentations or design projects.

Full Transparency Support

Preserves alpha channel transparency in all exported icons. Whether converting to PNG or ICO format, transparent backgrounds and semi-transparent pixels are maintained exactly as in the original icon resource.

Multiple Export Formats

Export in the format your work needs: PNG and TIFF with transparency, BMP, JPEG and GIF for legacy targets, ICO in single, combined or per-file mode and CUR with the hotspot kept. Copy to the clipboard or as a PNG data URI for HTML and CSS.

Batch Processing

Process multiple ICO, DLL or EXE files simultaneously. Load entire folders and extract icons from all files in one operation. Essential for extracting complete icon sets from system directories or application folders.

Visual Icon Preview

Preview all extracted icons in a visual grid before export. View icons at actual size or zoom in for detail inspection. Compare different size variants side-by-side to select the best resolution for your needs.

Search & Filter Icons

Filter extracted icons by size, color depth or resource index. Search through large icon collections from system DLLs containing hundreds of icons. Quickly locate specific icons without manual browsing.

Cursor and Animated Cursor Support

Open .cur cursors and .ani animated cursors, frame by frame. The cursor hotspot is read from the source and kept when you export back to CUR, so a converted cursor still clicks on the right pixel.

Opens Modern Windows App Packages

Open .msix and .appx app packages plus their bundles and pull the logo and tile art. Windows 10 and 11 .mun SystemResources files and .icl icon libraries open directly, 16-bit NE libraries included.

Website Favicon Grabber

Type any website address and the app collects its icons for you. It reads the declared icon tags on the page, checks the standard favicon location too and loads every icon it finds over HTTPS.

Create Multi-Size ICO from Any Image

Turn a PNG, JPG, BMP, GIF, TIFF or SVG into a proper multi-size Windows icon. Pick frame sizes from 16 to 256 or use a preset. SVG art is redrawn at every size, so each frame stays crisp instead of scaled.

Complete Favicon Package for the Web

One source image becomes a ready-to-deploy set: favicon.ico, the 16 and 32 pixel PNGs, apple-touch-icon, both android-chrome sizes, a site.webmanifest and an HTML snippet with the link tags ready to paste.

Duplicate Icon Detection

One click marks every repeated image across the whole load using pixel-level comparison, not file names. Skip the copies on export and keep one of each, then restore everything with Include All.

Built for Tens of Thousands of Icons

A virtualized grid keeps scrolling smooth with 40,000+ icons across 1,000+ files. Exports run in the background with a live progress counter and a working Cancel, so the app never freezes mid-batch.

Safe with Unknown EXE and DLL Files

Single-file .NET executables and modern .NET Core and .NET 5+ assemblies are read straight from their metadata. No target code ever executes, which keeps unknown binaries safe to inspect.

Export Options

Supported Export Formats

Export extracted icons in formats compatible with web development, design tools and Windows application development.

PNG Format

Portable Network Graphics

Best for web use, design projects and applications requiring transparency. Lossless compression preserves quality.

ICO Format

Windows Icon Format

Standard Windows icon format for apps, favicons and shortcuts. Export one frame, all frames in one file or one icon per source file.

BMP Format

Bitmap Image Format

Uncompressed format for legacy applications and maximum compatibility with older software systems.

TIFF Format

Tagged Image File Format

Lossless output with the alpha channel kept, suited to print pipelines and design tools that expect TIFF.

Comparison

Offline Icon Extractor: Better than Online Converters

This tool works offline, handles DLL/EXE files, offers better extraction accuracy and keeps every file private.

Univik ICO Converter

Any Windows Source: DLL, EXE, cursors, MUN and ICL libraries, MSIX packages and website favicons, far beyond plain ICO files.
All Icon Sizes: Access every embedded size from 16x16 to 512x512 with full transparency.
Batch Processing: Convert icons from multiple files and folders simultaneously.
Visual Preview: See all icons before export with zoom and grid view options.
Multiple Formats: Export to PNG, TIFF, BMP, JPEG, GIF, ICO or CUR based on your requirements.
Selective Export: Choose specific icons or sizes rather than extracting everything.
Offline & Private: Desktop software works without internet, so files stay private.

Online Icon Extractors & Converters

ICO Only: Most online tools only handle ICO files, cannot extract from DLL or EXE.
Limited Sizes: Often extract only one or two standard sizes, missing others.
Single File: Process one file at a time with manual uploads for each.
No Preview: Blind conversion without seeing what icons are available.
PNG Only: Usually limited to PNG output without ICO or BMP options.
All or Nothing: Cannot select specific icons - exports everything or nothing.
Privacy Risk: Files uploaded to unknown servers with uncertain data handling.

Frequently Asked Questions

Common Questions

Far more than ICO. It opens .ico, .cur, .ani and .res icon files, extracts resources from .exe, .dll, .ocx, .scr, .cpl, .drv, .mun and .icl files, opens .msix and .appx packages with their bundles and grabs favicons from any website address. That covers nearly every place a Windows icon can live.

The software extracts all standard Windows icon sizes including 16×16, 24×24, 32×32, 48×48, 64×64, 96×96, 128×128, 256×256 and 512×512 pixels. Any non-standard sizes embedded in the source files are also extracted and available for export.

Yes, you can extract icons from any DLL file including Windows system libraries like Shell32.dll, ImageRes.dll, DDORes.dll and others. These files contain hundreds of system icons that can be extracted and exported to PNG, BMP or ICO format.

Yes, full alpha channel transparency is preserved when exporting to PNG or ICO formats. This includes both fully transparent areas and semi-transparent pixels. BMP format does not support transparency, so transparent areas will appear as a solid background color.

Yes, ICO Converter supports batch processing. You can add files one by one or point it at an entire folder to process all supported files at once. All extracted icons are organized by source file for easy identification.

Seven formats plus 2 quick copies: PNG and TIFF keep transparency, BMP, JPEG and GIF are flattened for legacy targets, ICO exports a single frame, a combined multi-size file or one icon per source file and CUR keeps the cursor hotspot. Any icon also copies to the clipboard or as a PNG data URI.

No, ICO Converter is a desktop application that works completely offline. Your files are processed locally on your computer and never uploaded to any server. This keeps your icon files fully private and secure.

The demo edition gives full viewing and inspection of everything you load. Batch exports are limited to a fixed number of items per operation, with a clear message when you reach it. Licensed editions remove the limit and show the edition name in the status bar.

Add the .exe file to ICO Converter, preview the embedded icons, select the ones you need and export them as PNG, BMP or ICO. As an EXE icon extractor it pulls every icon resource from the executable, all on your PC.

Yes. Extract the icon from any EXE and export it as an ICO file. This makes ICO Converter a quick way to convert EXE to ICO. You can also extract icons from DLL files the same way.

For privacy and range, yes. Online icon extractors need you to upload your EXE and DLL files and often handle ICO only. This desktop tool works offline, never uploads anything, reads everything from cursors to MSIX packages and exports to 7 formats plus the clipboard.

Yes. .cur cursor files open with their hotspot read from the file. .ani animated cursors open frame by frame. Export a cursor back to CUR and the hotspot is kept. Any frame also converts to PNG or ICO like a normal icon.

Yes, both. Create ICO from Image turns a PNG, JPG or SVG into a multi-size Windows icon with the frame sizes you pick. Create Favicon Package goes further: from one image it writes favicon.ico, the standard PNG sizes, apple-touch and android-chrome icons, a site.webmanifest and a paste-ready HTML snippet.

Yes. Open a .msix or .appx package or a whole bundle and the logo and tile art comes out. Windows 10 and 11 .mun files from SystemResources open like any other library. Prefer doing it by hand with free tools? Our icon extraction guide walks through every manual method.
