ICO sizes

Best for photo favicons

Use JPG to ICO when your source image is a photo, logo mockup or compressed JPEG graphic that needs to become a website favicon.

Private JPG conversion

Your JPG file stays in the browser. The ICO output is generated locally and is not uploaded to a server.

Recommended favicon sizes

Generate common ICO sizes such as 16×16, 32×32, 48×48, 128×128 and 256×256 for broad browser and desktop support.

JPG-specific preparation

How to make a clear favicon from a JPG photo

JPEG files are designed for photographs and do not contain transparent pixels, so the crop, background and contrast matter more at small favicon sizes.

Crop around one subject

Use a tight square crop around the face, product or symbol. Wide photographs lose recognizable detail when reduced to 16×16 or 32×32.

Choose the background first

JPG has no alpha transparency. Any white, dark or colored background in the source remains visible in every generated ICO size.

Avoid repeated JPEG compression

Start with the highest-quality original available. Compression blocks and ringing become more visible around sharp logo edges after resizing.

Format-specific help

JPG to ICO questions

Will a JPG favicon have a transparent background?

No. JPG does not support transparency, so the source background is preserved. Use PNG to ICO or SVG to ICO when transparency is required.

What JPG dimensions work best?

A square image of at least 256×256 pixels is a practical source. Larger images are acceptable when the main subject is centered and clearly cropped.

Does converting JPG to ICO improve image quality?

No. The converter resizes and packages the existing pixels; it cannot restore detail already removed by JPEG compression.

Are JPG files uploaded?

No. The JPG is decoded and converted locally in your browser.
