Compress Image for Website Background (Under 250 KB WebP)
Background images can afford lower quality (75) because text overlays hide artefacts.
Your images stay on your device. Nothing is uploaded.
Website background images sit behind text overlays that mask JPEG/WebP compression artefacts. That lets you drop quality to 75 without visible degradation — meaningful bytes saved on every page load.
This preset produces a 2400 px WebP at quality 75 — retina-safe on 4K displays, background-optimised.

Frequently asked questions
- How much can I shrink images for website background?
- Typical reductions are 60–85% with no visible quality loss using the defaults on this page. Website background images sit behind text overlays that mask JPEG/WebP compression artefacts. That lets you drop quality to 75 without visible degradation — meaningful bytes saved on every page load.
- What format is best for website background?
- For website background the preset above outputs WEBP at quality 75 — the sweet spot for this workflow's LCP and CWV budget.
- Will compression break transparency or animation?
- Transparency is preserved when the output format supports it (PNG, WebP, AVIF). Animation is preserved for animated WebP. JPEG output flattens transparency to white.
- Can I compress dozens of images at once?
- Yes — use the bulk compressor. Drop a folder or multi-select files; the queue processes them in order with progress per file, and you can download all results as a ZIP.
- Do my images get uploaded anywhere?
- No. The tool runs entirely in your browser — important for client work, internal assets, and anything not yet published.
