Heavy heroes drag Lighthouse scores and mobile load times. Prep assets to the size they actually display, then compress or convert to a web-friendly format.

A2Z Edit covers resize, compress, and format conversion without a design-tool export maze.

Do this on A2Z Edit

Open the Image Compressor and follow the steps below.

How to Prepare an Image for a Website

  1. Note the maximum display width in your layout (for example 1280px).
  2. Resize the source so it is not many times larger than that display size.
  3. Compress or convert to WebP/JPG depending on browser support you need.
  4. Crop to the final aspect ratio used in the design.
  5. Strip unnecessary metadata before uploading to the CMS.

Why it matters

Serving 4000px photos into a 600px column wastes bandwidth.

Format choice (WebP vs JPG) is a simple win for many blogs and shops.

Tips

  • Export 2× only when you truly need retina density for that slot.
  • Keep originals in cloud storage; upload optimized derivatives to the site.
  • SVGs for logos beat photos of logos whenever possible.

Frequently asked questions

WebP or JPG for the web?

WebP is often smaller with good support in modern browsers. Offer JPG when you must support older clients without negotiation.

Is there a signup?

No. A2Z Edit has no login or signup — open the tool and start.
