What is a JPG file?
JPG is still the default camera and export format for many photo workflows. It uses lossy compression and works almost everywhere. That broad support is why teams often keep JPG as the source file even when the website delivers WEBP.
For public web performance, WEBP is usually the better delivery format. Major browsers support it, and the size savings can be meaningful on image-heavy pages. Convert delivery copies, and keep the JPG if partners still need the classic format.

| Compression type | Lossy only | Lossy or lossless |

| Browser and app compatibility | Near-universal, including older software | Strong in modern browsers; weaker in some older desktop apps |

Convert on iPhone, Windows, and Mac
iPhone
Use this page in Safari or Chrome when you need a quick WEBP for a CMS upload. Native iOS export menus may not expose WEBP for every photo. A browser convert is often the shortest path.
Windows
Design tools and build scripts can export WEBP, but setup takes time. For a single asset or a small set of hero images, this JPG to WEBP converter avoids installing codecs or CLI tools.
Mac
Some Mac apps can export WEBP, but support still varies by version. Convert here when you want a browser-based step before uploading to your site or design handoff folder.
Is this converter safe?
Conversion runs in your browser. Your JPG is not uploaded to our servers for processing. That is useful for draft product shots and unpublished marketing assets.
Keep the original JPG as a master file. Deploy the WEBP for performance, and re-export if quality settings need another pass. Inspect the download at full size before publishing.
