Web Images & Favicons: Formats, Sizes, and Free Tools

Icons, favicons, and images affect how your site looks and loads. Getting the right sizes and formats doesn't require expensive software—free browser-based tools can generate favicons, convert formats, compress images, and strip metadata. This guide walks you through the basics.

Favicons: What You Need

A favicon is the small icon that appears in browser tabs and bookmarks. Sites typically need 16×16 and 32×32 for browsers, and 180×180 for Apple touch icons. Instead of resizing by hand, use a favicon generator to upload one image and download all common sizes as PNGs. Drop your logo or icon, get 16×16, 32×32, 48×48, and 180×180 in one go—no signup, everything runs in your browser.

Image Formats for the Web

JPG is best for photos, PNG for graphics and transparency, and WebP for smaller file sizes when browsers support it. Convert between them as needed: use our PNG to WebP or WebP to PNG converters to switch formats without leaving your browser. WebP often reduces size by 25–35% compared to JPG or PNG while keeping quality.

Keep File Sizes Down

Large images slow down pages. An image compressor lets you reduce file size with a quality slider—lower quality means smaller files. For hero images and photos, compressing before upload can significantly improve load times. Our compressor works on JPG, PNG, and WebP and runs entirely in your browser.

Resize for Layouts

Uploading full-resolution images when you only need 800px wide wastes bandwidth. Use an image resizer to scale down to preset dimensions (e.g. social sizes) or custom width and height. Resizing before upload keeps pages fast and responsive.

Check or Strip Image Metadata

Images can contain EXIF data (camera, location, etc.). For privacy or smaller files, you may want to remove it. An image metadata viewer shows dimensions, file size, and type; you can then download a copy without metadata. Useful for protecting privacy or trimming a few extra bytes.

Best Practices

• Provide at least 16×16 and 180×180 for favicons and Apple devices
• Prefer WebP for photos when you can; fall back to JPG for compatibility
• Compress and resize images before uploading to improve performance
• Strip metadata from images if you care about privacy or file size
• All tools mentioned run locally—your images never leave your device

Conclusion

Favicons, formats, compression, and metadata don't have to be complicated. Free online tools handle favicon generation, format conversion, resizing, and metadata stripping directly in your browser. Use them to get your web images and icons right without installing software or sending files to a server.
