+
+Save an image from a website lately? Chances are it arrived as `.webp` — and then refused to open in your photo printer, CMS or ancient image viewer. Converting takes seconds once you know why this happens.
+
+## Why everything is WebP now
+
+Google designed WebP to make pages faster: identical-looking images are typically 25–35% smaller than JPEG. Browsers adopted it enthusiastically, so servers now serve it by default. The catch is that plenty of non-browser software — older Office versions, some printers, certain editing tools — never caught up.
+
+## Convert in three steps
+
+1. Open [WebP to JPG](/webp-to-jpg).
+2. Drop your files onto the upload area.
+3. Download the JPGs — quality is preserved at 85%, indistinguishable from the source for photos.
+
+Need transparency preserved? Use [WebP to PNG](/webp-to-png) instead; JPG has no alpha channel, so transparent areas would flatten to white.
+
+## Should you ever go back *to* WebP?
+
+If you manage a website: yes. Serving [JPG as WebP](/jpg-to-webp) is free performance — same pixels, smaller transfer, better Core Web Vitals. Keep JPG masters, generate WebP for delivery.
+
+## Quick decision table
+
+| Situation | Best format |
+|---|---|
+| Opening in old software | JPG |
+| Photo with no transparency needs | JPG |
+| Logo / graphic with transparency | PNG |
+| Website images you serve yourself | WebP |
+
+## Troubleshooting
+
+- **"File could not be read as an image"** — some sites deliver AVIF with a `.webp` extension. Our converter reads actual file content, not just names, so these still work.
+- **Colors look slightly different after conversion** — that is wide-gamut color profiles being flattened; acceptable for almost all uses.
+
+## FAQ
+
+**Does converting reduce quality?**
+One conversion at high quality (85+) is visually lossless for photographs. Repeated re-saves compound loss, so keep originals.
+
+**Can I convert many at once?**
+Yes — drop multiple files; each converts independently.
