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?

Fast, browser-based JPE to ICO conversion that balances icon fidelity and small file size for apps and websites

Fast Local Conversion

Convert JPE images to ICO directly in your browser with minimal upload and instant processing.

Preserve Visual Fidelity

Retains raster detail from high-resolution JPE sources when scaled down to typical icon sizes.

Wide Platform Support

Generate ICO files compatible with Windows shells and many legacy app icon systems.

Simple Size Controls

Pick common icon dimensions so you control pixel scaling and resulting file-weight tradeoffs.

Smart Resampling

Bicubic resampling reduces aliasing when converting photographic JPE images to small icons.

Client-side Processing

Files are processed locally in the browser to reduce network transfer of source images.

Tips and Best Practices

Optimize your conversion workflow with technical recommendations.

Prepare JPE for Iconization

Crop the JPE to the primary subject to preserve recognizability at 16x16 and 32x32
Convert source to sRGB to reduce color shifts when ICO embeds PNG entries
Remove heavy JPEG compression artifacts by re-saving at higher quality pre-conversion
Resize the JPE to the largest needed icon dimension to minimize in-converter resampling
Supply a pre-processed alpha matte as PNG if you require a precise transparent boundary

Control Output Encoding

Choose PNG-backed ICO entries to obtain 32-bit RGBA and smooth alpha edges
Prefer uncompressed BMP entries only when legacy tooling requires them despite larger files
Generate multi-resolution ICO entries (16,32,48,256) to support various UI scales
Avoid embedding full-resolution JPE inside ICO; downscale first to save binary size
Inspect resulting ICO bit-depth to confirm intended 24-bit/32-bit representation

Verify Visual Results

Preview each ICO size in intended UI contexts to detect lost fine details
Check anti-aliasing around edges when PNG alpha is used versus mask-based transparency
Compare color rendering on target OS because ICC mapping may differ between viewers
Open the ICO in editors like IcoFX or Windows resource viewer to validate embedded sizes
Test file in the actual application or browser to ensure correct icon selection at runtime

Workflow and Performance

Process batches in groups of 20-50 JPEs to balance memory and throughput in-browser
Close memory-heavy browser tabs and apps to free RAM for large multi-size ICO generation
Export a separate ZIP of generated ICOs to streamline distribution to development teams
Keep original JPE archives for re-export if different icon crops or profiles are later required
Validate sensitive images locally since processing happens client-side and network transfer is minimal

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.
