Frequently Asked Questions

Favicons

Where should I place my favicon?

The recommended location is /favicon.ico in the root of your domain. Browsers automatically request this file even if you don’t include a <link rel="icon"> tag.

Do I need both favicon.ico and favicon.png?

Not necessarily. The .ico format is still the most compatible because it can contain multiple resolutions inside one file. PNG favicons work in modern browsers, but older systems and crawlers may ignore them.

What sizes should a favicon include?

  • 16×16 — classic browser tab
  • 32×32 — high‑DPI tabs
  • 48×48 — Windows icons
  • 64×64 — high‑resolution displays

Why do some devices require larger icons?

Mobile platforms (iOS, Android) and OS tiles (Windows) use larger icons:

  • 120×120 — iPhone
  • 152×152 — iPad
  • 192×192 — Android Chrome
  • 256×256 — Windows tiles

Does this tool upload my images?

No. All processing happens locally in your browser using JavaScript and Web Workers. Your images never leave your device.

Image Conversion

Which formats are supported?

The converter supports:

  • PNG
  • JPEG / JPG
  • WEBP
  • BMP
  • SVG (raster embedded)

Does converting reduce image quality?

Lossy formats (JPEG, WEBP) may reduce quality. Lossless formats (PNG, BMP) preserve pixel data. Converting from lossy → lossless does not restore lost quality.

Why does SVG output contain a raster image?

Browsers cannot convert arbitrary raster images into vector shapes automatically. Therefore, the tool embeds a PNG inside an SVG container for compatibility.

Is there a file size limit?

The limit depends on your browser’s memory. Most modern browsers handle images up to 20–40 MB without issues.

Password Generator

How secure are the generated passwords?

Passwords are generated using JavaScript’s cryptographically strong random functions where available (crypto.getRandomValues). They are never sent to a server.

Can I generate multiple passwords at once?

Yes. The tool allows generating up to 50 passwords in one click.

What character sets can I use?

  • Lowercase letters (a–z)
  • Uppercase letters (A–Z)
  • Digits (0–9)
  • Symbols (!@#$%^&*)
  • Your own custom character set

Are passwords stored anywhere?

No. Everything is generated locally and disappears when you close the page.

General Questions

Does this website store or upload my files?

No. All tools work entirely in your browser. Nothing is uploaded or stored.

Why do some features require a modern browser?

The tools rely on:

  • Web Workers
  • OffscreenCanvas
  • createImageBitmap
  • crypto.getRandomValues

These APIs are supported in all modern browsers but may not work in outdated ones.

Can I use these tools offline?

Yes. Once the page is loaded, all processing happens locally. You can even save the site and run it from your computer.

Is everything free?

Yes. All tools are free for personal and commercial use.
