What is Favicon Generator?

Favicon Generator is a tool that lets you generate crisp favicons for your website. It belongs to the Special Tools family of utilities on T4UHubIMG. Instead of installing heavy software or trusting a server with your private photos, you do everything directly in your web browser — the work happens on your own computer or phone.

Why it matters

Images are everywhere — websites, social media, job applications, exam forms, online stores and messaging apps. Each context has different requirements for size, dimensions and format. Getting these wrong leads to blurry uploads, rejected forms, slow-loading pages and wasted time. Favicon Generator solves a specific, common problem quickly and reliably.

How to use Favicon Generator step by step

Step 1: Upload your image

Drag and drop your file into the upload area, click to browse, or paste an image directly from your clipboard.

Step 2: Adjust the settings

Use the settings panel to fine-tune the result for favicon generator. Sensible defaults are pre-filled so you can also just continue.

Step 3: Process the image

Click the Process button. Everything runs instantly in your browser — no waiting for uploads or servers.

Step 4: Download the result

Preview the output, then click Download to save the optimized image to your device. Use Reset to start over.

Best practices

Start from the highest-quality original you have; you can always reduce quality, but you cannot add detail back. Choose the right output format for the job — WEBP for small modern web images, PNG for graphics and transparency, JPG for photographs. When a platform or form specifies exact requirements, match them precisely rather than guessing.

Keep a copy of your original file before processing, and double-check the output dimensions and file size in the info panel before you use the result somewhere important.

Common problems & how to fix them

The output looks blurry

This usually happens when an image is enlarged beyond its native resolution. Start with a larger source image, or reduce how much you upscale.

The file is still too large

Lower the quality slider, switch to JPG or WEBP, or use a dedicated "compress to size" tool that targets an exact file size.

My format isn't supported

Some formats (like HEIC, RAW, PSD or TIFF) rely on what your browser can decode. Convert to JPG or PNG first, or use a browser that supports the format natively.
