Transforming a JPG into a Great Favicon

Using a JPG as a source is common, especially when you want to convert a photo to an icon. Since JPGs don't support transparency, our icon generator from image gives you the option to set a solid background color to ensure your icon looks polished. For best results, start with a high-resolution image to minimize compression artifacts when scaling down to 16x16 pixels.

When a JPG source is fine (and when it isn't)

JPG is a lossy format. For icons with flat shapes, gradients or photos, it can work well. For logos with crisp edges, prefer PNG/SVG sources to avoid ringing/blocks at 16–32 px. If JPG is your only source, export a high‑quality version (90–95%) at 1024×1024+ to minimize artifacts before downscaling.

Reduce artifacts before conversion

  • Upscale from the master (not from a small copy).
  • Avoid re‑saving multiple times; each JPG pass compounds artifacts.
  • If edges look fuzzy at 16 px, try the Sharp profile in IcoSmith.

JPG to favicon (.ico)

Convert JPG to favicon (.ico) quickly and privately. Prefer high‑quality input to avoid artifacts at 16×16; preview small sizes before exporting.

Recommended ICO sizes

  • 16×16, 32×32: browser tabs.
  • 48×48, 64×64: Hi‑DPI desktop.
  • 128×128, 256×256: Windows/legacy contexts.

Choose transparent background when possible; if the JPG has a background, set a solid color that matches your brand’s dark/light theme.

Step‑by‑step

  1. Open IcoSmith and upload your JPG.
  2. Select sizes 16–256; choose transparent or solid background.
  3. Preview 16–32 px; toggle Sharp vs Soft if thin strokes blur.
  4. Export the ICO or the full package (links + manifest + mask icon).

Performance, caching and SEO

  • Cache icons for a year; bump a query string when updating.
  • Include canonical URL and hreflang (EN/PT‑BR/ES) for localized pages.
  • Provide Apple Touch 180×180 and Safari mask icon color.
