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.

Why Choose Our Converter?

Convert CR2 camera RAW images to ICO favicons quickly and accurately for cross-device use and app icons.

Fast RAW Rasterization

Hardware-accelerated decoding of CR2 frames to flattened bitmaps in seconds for quick icon generation.

Preserve Visual Detail

High-quality demosaicing and downscaling to retain important detail when creating small ICO sizes.

Batch Icon Packs

Process dozens of CR2 files into multi-size ICOs in one operation to streamline favicon workflows.

Wide Icon Support

Produce ICO files containing multiple resolutions compatible with Windows, browsers, and desktop apps.

Configurable Sizes

Select target icon sizes and scaling filtering to optimize for clarity at 16–256 px resolutions.

Client-Side Processing

Conversions run in the browser memory to limit external upload exposure and protect originals.

Source vs Target Format

Key technical differences between formats

Feature	Source Format	Target Format
Compression	High efficiency (RAW sensor data, lossless-ish)	Uncompressed or PNG-compressed bitmaps inside ICO
File Size	Large (multi-megabyte RAW)	Small to moderate (multi-resolution ICO)
Quality	High dynamic range, high bit depth	Lossy bit-depth reduction to 8-bit per channel
Transparency	No native alpha in RAW	Supported (ARGB or PNG) inside ICO
Metadata	EXIF, MakerNotes, camera info	Minimal; ICO does not carry EXIF reliably
Primary Use	Photo editing and archival	Icons, favicons, UI assets

Tips and Best Practices

Optimize your conversion workflow with technical recommendations.

Prepare RAW for Iconization

Crop CR2 to the subject area to improve legibility at 16–32 px icon sizes
Apply white balance and exposure adjustments in a RAW editor before conversion to control final tone mapping
Convert CR2 to a high-quality TIFF if you need consistent color before ICO rasterization
Remove complex backgrounds in source CR2 using masking to enable accurate ICO transparency
Flatten any additional edits so the converted bitmap matches your intended visual hierarchy

Optimize ICO Encoding

Select PNG-compressed entries for ICO when transparency is required to save file size
Include multiple resolutions (16,32,48,256) so Windows and browsers pick the best match
Prefer 32-bit ARGB entries only when transparency matters; otherwise use 24-bit for smaller output
Test resulting ICO in target operating systems to verify internal PNG vs BMP compatibility
Keep original CR2 files archived in case iterative edits are needed after viewing icons

Verify Visual Fidelity

Inspect icons at real target sizes to confirm contrast and recognizability from CR2 source
Compare color rendering between sRGB-rendered ICO and your camera's CR2 preview for shifts
Zoom to 100% on converted 32 px entry to check for aliasing introduced during downscaling
Validate transparency edges if automatic masking converted CR2 backgrounds to alpha
Use icon editors to replace specific ICO entries if a particular size needs manual retouch

Workflow Stability & Privacy

Process CR2 batches in groups of 20–50 to avoid browser memory constraints and crashes
Run conversions locally in the browser to keep raw images on your device and protect IP
Close other heavy tabs to free RAM when converting large CR2 files to multiple ICO sizes
Verify each ICO output immediately and download ZIPs to local storage to avoid reprocessing
When using automated masking for transparency, double-check edge extraction for halos

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.
