What file formats do you support?

We support over 100 file formats including images (JPG, PNG, GIF, WebP, TIFF), documents (PDF, DOC, DOCX, TXT), videos (MP4, AVI, MOV), audio (MP3, WAV, FLAC), and many more specialized formats.

Yes, absolutely. We use enterprise-grade encryption for all file transfers. Your files are automatically deleted from our servers after conversion, and we never store or access your personal data.

What is the maximum file size?

The maximum file size for free users is 100MB per file. Premium users can convert files up to 1GB. For larger files, we recommend our batch processing feature.

How long does conversion take?

Most files convert in under 30 seconds. The exact time depends on file size and format complexity. Our advanced algorithms ensure the fastest possible conversion while maintaining quality.

Can I convert multiple files at once?

Yes! Our batch processing feature allows you to upload and convert up to 50 files simultaneously. This is perfect for bulk conversions and saves significant time.

Do I need to create an account?

No account is required for basic conversions. However, creating a free account gives you access to batch processing, file history, and priority support.

Source vs Target Format

Key technical differences between formats

Feature	Source Format	Target Format
Compression	Raw sensor (lossless linear capture)	PNG-compressed raster inside ICO
File Size	Large (tens of MB typical)	Small to moderate (KB range per icon)
Quality	High dynamic range, high bit depth	Lossy downsampled to 8-bit sRGB PNG
Transparency	Not native; requires editing	Supported as 32-bit PNG entries
Metadata	EXIF, XMP, camera tags	Minimal or none in ICO container
Primary Use	Professional raw editing and archival	Desktop and browser icons, favicons

How to Convert Files

Follow these simple steps to convert your files

Upload Source File

Select or drag and drop your ARW raw files into the converter interface.

Adjust Settings

Pick target icon sizes, enable alpha if needed, and choose PNG compression level.

Convert

Start conversion to decode ARW, rasterize to sRGB PNGs, and pack them into an ICO container.

Download Result

Save the ICO file or ZIP containing multiple ICO variants for different platforms.

Tips and Best Practices

Optimize your conversion workflow with technical recommendations.

Prepare RAW for Icon Use

Demosaic ARW in a raw editor to apply desired white balance before packing
Crop to square focal area to maximize recognizability at 16–32px
Apply conservative sharpening at full resolution to retain edge clarity after downsampling
Set output color space to sRGB to match browser icon rendering expectations
Flatten any compositing layers in the raster stage so ICO receives a single PNG frame

Optimize Output Sizes

Generate only needed sizes (16/32/48/128) to reduce ICO footprint
Use higher PNG compression for photographic icons to trade CPU for smaller delivery
Avoid exporting excessively large PNGs into ICO; browsers pick nearest size and scale
Strip nonessential metadata before packing to lower ICO file size
Preview small-size results at 100% to confirm legibility before publishing

Verify Visual Fidelity

Compare ARW tonal range vs ICO raster at 32px to confirm highlight detail retention
Check color shifts after sRGB conversion and adjust camera profile pre-rasterization
Test alpha edge blending on various backgrounds to ensure icon crispness
Inspect downsampled icons on Windows and macOS to catch platform-specific scaling artifacts
Use pixel grid preview for 16px icons to refine contrast and symbol clarity

Workflow and Privacy

Keep originals: retain ARW files for archival and re-exports at different sizes
Process batches of 20–50 ARW files to balance memory use and speed in-browser
Perform sensitive conversions locally; browser-based processing avoids server uploads
Close other memory-heavy apps while converting high-megapixel ARWs to avoid swap
Download generated ICOs immediately and verify before removing source files

Fast Processing

Close unused tabs for maximum throughput.

Client-Side Privacy

No media leaves your device.

Broad Compatibility

Output files work across all operating systems.

Pro Tip

For batch conversions, process in groups of 20-50 files to optimize memory usage and avoid browser slowdowns.
