How to Convert Images for a Website
Website images need the right format and size — not just a camera export renamed for upload. Convert a delivery copy for the CMS while keeping an editable master.
Quick take: Photos → WebP/AVIF (JPG fallback). UI/screenshots → PNG or lossless WebP. Logos → SVG (PNG fallback). Always resize to the slot first.
Start from the right master
Keep HEIC/RAW/PNG masters for edits. Convert copies for the site so you can re-export later without generational loss.
Pick a delivery format
Modern sites prefer WebP or AVIF for photos. JPG remains the safest fallback. PNG keeps sharp UI and transparency. SVG scales logos cleanly.
Convert privately, then upload
Use Format Convertly converters in your browser — nothing is uploaded to a third-party queue — then place the result in your CMS or static assets folder.

FAQ
Do I need both WebP and JPG?
Often yes for broader compatibility — many stacks serve WebP/AVIF with a JPG/PNG fallback.
Should I convert logos to JPG?
No. Prefer SVG or PNG so edges stay sharp and backgrounds can stay transparent.
