Build useful link rel preload tags

Web teams use it when a decisive asset deserves priority but preloading everything would waste bandwidth and weaken the signal.

Build useful link rel preload tags. The result stays in your browser, ready to review, copy and adapt without an account or any transfer of your input.

How to use

List one resource per line, such as a font file or a key image.
Use the exact paths that your page requests.
Run the generator to create the link rel preload tags.
Insert those tags in the head before other priority resources.

Example

A team notices that the title font arrives late and shifts the layout. They list the font file used by the page, generate the preload tags and place them in the head. This helps them avoid preloading every asset on the site. A slow-network test then shows whether the font priority is useful.

Input

/assets/font.woff2
/assets/hero.webp

Limits and formats

Preloading is useful only for a few genuinely critical resources.
An incorrect path prevents the browser from finding the file.
Too many tags can delay other useful elements.
The tool does not check whether the resource is already cached.
Browsers may ignore a preload that is unnecessary or malformed.

Where processing happens

The paths you enter are turned into tags inside your browser. No file is sent away and the tool does not trigger network calls. The generated code stays available for you to copy.

Frequently asked questions

Which resources should I preload?

Reserve preloading for files needed in the first render, such as a heading font or a hero image. Preloading too many items weakens the priority signal. Check with browser tools to see whether the change helps.

How is this different from lazy loading?

Preloading asks the browser to fetch a resource earlier. Lazy loading delays resources that are not needed yet. They solve opposite problems and should be used for different assets.

Can I preload an external font?

You can enter a relative or absolute path depending on your setup. Make sure it matches the file your page actually serves. Cross-origin and security rules can still affect how the browser uses it.
