JPEG을 WEBP로 온라인 변환 — 무료 & 빠름

WebP는 Google이 웹을 더 빠르게 만들기 위해 특별히 만들었습니다. JPG 이미지를 WebP로 변환하면 동등하거나 더 나은 시각적 품질을 유지하면서 파일 크기가 25-34% 줄어듭니다. 모든 주요 브라우저가 이제 WebP를 기본으로 지원합니다—Chrome, Firefox, Edge, Safari 14+.

왜 JPEG을 WEBP로 변환하나요?

⚡

더 빠른 페이지 로드

25-34% 더 작은 파일이 페이지 무게를 줄여 TTFB와 LCP 점수를 크게 개선합니다.

📈

더 나은 SEO

Google은 더 빠르게 로드되는 페이지에 더 높은 검색 순위를 부여합니다. 이미지 최적화는 핵심 요소입니다.

📱

모바일 우선

더 작은 WebP 파일은 모바일 데이터를 덜 소비하고 더 느린 연결에서 더 빠르게 렌더링됩니다.

🌐

현대 브라우저

Chrome, Firefox, Edge, Safari 14+는 WebP를 기본으로 렌더링합니다. 플러그인 필요 없음.

WEBP

파일 확장자.webp
설명WebP provides superior lossless and lossy compression for images on the web. WebP images are typically 25-34% smaller than comparable JPEG or PNG files.

기능

JPEG (소스)

WEBP (대상)

🗜️압축

Lossy

Lossy+Lossless

🔍투명도

Not supported — transparent areas always render as solid white or the specified matte color

Full 8-bit alpha channel — same capability as PNG, with better compression efficiency

🎬애니메이션

Not supported

Supported — animated WebP stores multiple frames with per-frame timing data, offering vastly better quality and smaller files than animated GIF

🎨색 깊이

24-bit (8 bits per channel: RGB) — up to 16.7 million colors

24-bit RGB + 8-bit alpha — 16.7 million colors with full alpha transparency

📦파일 크기

50 KB – 5 MB per image depending on resolution and quality setting

25–35% smaller than an equivalent-quality JPEG or PNG — typically 30–80 KB for standard web images

🌐브라우저 지원

Universal — all browsers, all operating systems, all devices including IE6 and older smartphones

Chrome 23+, Firefox 65+, Edge 18+, Safari 14+, Opera 12+. Not supported in Internet Explorer or Safari prior to iOS/macOS in 2020.

JPEG

{from} 형식 정보 JPEG

Standardized in 1992 by the Joint Photographic Experts Group, JPEG became the internet's dominant image format through the 1990s. Its DCT compression made digital photography practical for early web and digital cameras, enabling photo-sharing at a time when dial-up connections made large files impractical. Today it remains the default format for cameras, smartphones, and photo-sharing platforms worldwide.

장점

+Smallest file sizes for photographs (10:1 to 20:1 compression ratio)

+Universal compatibility across every device, software, and platform

+Embeds EXIF metadata (GPS, camera settings, date/time)

+Adjustable quality/size trade-off at save time

+Native support in every digital camera and smartphone

단점

−Lossy — permanently discards image data with every save

−No transparency — backgrounds are always solid

−Visible block artifacts on sharp edges, text, and high-contrast areas

−Quality degrades with each re-save (generational quality loss)

−Limited to 8-bit per channel (no HDR or 16-bit depth)

사용 시기

→Sharing photographs on social media, email, or blogs

→Camera images where file size matters more than pixel perfection

→Web page photos where page load speed is the priority

→Any context requiring maximum cross-device and software compatibility

팁

•Quality 85–95% delivers the optimal balance between file size and visual quality

•Never re-save a JPG after editing — use PNG or TIFF as your working master file

•Use PNG or WebP for logos, text, and graphics with sharp edges instead

•Strip EXIF metadata before web publishing to trim 5–20 KB per image

WEBP

{from} 형식 정보 WEBP

Google developed WebP and announced it in 2010 using technology from the VP8 video codec. Initial adoption was Chrome-only, but Firefox added support in 2019 and Apple's Safari 14 followed in 2020 — finally making WebP viable for all modern web deployments without compatibility caveats. It is now Google's officially recommended image format for web performance optimization.

장점

+25–34% smaller than JPEG/PNG at equal quality — direct page load improvement

+Both lossy and lossless compression modes in a single format

+Full alpha transparency like PNG at significantly smaller file sizes

+Animated WebP replaces GIF with full-color quality and dramatically smaller files

+Directly improves Google Core Web Vitals (LCP) and PageSpeed scores

단점

−Not supported in Internet Explorer or Safari before iOS 14 / macOS Big Sur

−Print shops, Outlook, and Office apps don't accept WebP

−Limited native support in professional desktop imaging software

−Not practical for offline print workflows requiring Photoshop or Lightroom native support
