A plain-English guide to compressing and converting images for faster pages. Reduce size without visibly losing quality using Bagiqo tools.
Web performance often comes down to images. They are usually the largest single part of a page, and a small change in how you export them can cut page weight dramatically.
Start by compressing what you already have. The image optimizer lets you adjust quality until the file is small and still sharp.
Simple workflow that works
- Compress with the image optimizer first.
- Convert to a modern format when it helps: PNG to JPG, WebP to AVIF and JPG to PNG.
- Keep a lossless master and ship a compressed copy.
Key principles
- Choose the right format for the content (photo vs graphic).
- Do not re-compress an already-compressed image.
- Serve a sensible size — do not deliver a 4000px image in a 600px box.
Pair with fast hosting and a CDN for the biggest speed win.
