Your practical roadmap
Follow the steps in order, check each result before moving on, and use the final checklist to confirm your work.
Large images can slow pages and consume mobile data. Choose dimensions appropriate to the displayed size, use modern formats where supported, and preserve visual quality. ## Step-by-step instructions 1. Identify the actual display dimensions for each image. 2. Resize oversized originals before uploading. 3. Export photographs as WebP or AVIF when the workflow supports them, with suitable fallbacks. 4. Use SVG for appropriate simple vector graphics. 5. Set width and height to reserve layout space and lazy-load below-the-fold images. 6. Compare file size and visual quality on a real device. ## Final checks - Test the result in a realistic situation before relying on it. - Keep a note of any settings or decisions that need future review. - Recheck the process when your tools, hosting, or requirements change.
Performance investigation checklist
Measure the page on a representative device and connection before changing code.
Identify whether delays come from server response, scripts, fonts, images, layout, or third-party services.
Resize media, reserve layout space, and defer non-critical resources.
Remove unused dependencies only after confirming required features still work.
Retest after each meaningful change under similar conditions.
Avoid optimisation by guesswork
Lab scores help diagnose problems but do not represent every visitor. Review field data where available and protect correctness, accessibility, and reliability while improving speed.
Useful next steps for your project
If this guide is part of a real website project, use a hosting provider for the server setup and a development partner for the build itself.
Costs and budget tipsList one-off setup costs and recurring expenses separately. Check renewal pricing, usage limits, taxes, cancellation terms, and whether the free plan permits your intended commercial use.
Prices and plan terms can change and may vary by country, billing period, taxes, and exchange rate. Confirm the current price on the provider’s official website before purchasing. Links are provided for practical reference and do not guarantee a particular result.
