JPG to WebP Converter

How to Convert JPG to WebP Online

1. Upload Your JPG Images: Click "+ Add Files" or drag and drop JPG, JPEG, and JFIF files from your computer. Batch upload is supported, so you can convert an entire image folder in one pass.
2. Pick a Quality Preset: The default is Very High (Recommended), which matches the visual quality of a quality-92 JPEG while typically producing a 25-30% smaller file. Drop to High or Medium for hero images and thumbnails where extra savings matter more than the last few percent of fidelity, or switch on Specific file size to target a hard byte cap.
3. Set Lossless and Resolution (Optional): Toggle Lossless? to Yes for graphics, screenshots, and UI assets where every pixel matters — pick No (Recommended) for photos. Resize using Resolution Percentage, a Preset Resolution (e.g. 1080P, 720P, 480P), or exact Width x Height with aspect ratio locked.
4. Convert and Download: Click Convert, then download each WebP individually or grab everything as a ZIP. Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically after a few hours — no sign-up, no watermark, never shared.

Why Convert JPG to WebP?

WebP is Google's open image format, designed specifically to deliver smaller files than JPEG and PNG at matched visual quality. According to Google's developer documentation, WebP encodes photographs roughly 25-34% smaller than a JPEG at the same SSIM-matched quality, and supports both lossy and lossless compression in a single container — something JPEG cannot do. For an image-heavy site, swapping JPG for WebP typically cuts page weight by hundreds of kilobytes per view.

• Core Web Vitals and SEO — Lighthouse's "Serve images in next-gen formats" audit explicitly flags JPEG and PNG and recommends WebP or AVIF. Reducing image bytes improves Largest Contentful Paint (LCP), which is a confirmed Google ranking signal under the Page Experience framework.
• ~96% browser reach — Chrome, Firefox, Edge, Opera, and Android browsers have supported WebP since 2014; iOS Safari added partial support in version 14 (Sept 2020), with full support from Safari 16. caniuse.com currently reports ~96% global support, with the remainder served by an HTML <picture> fallback.
• Transparency without bloat — Unlike JPEG, WebP supports an alpha channel. A 24-bit PNG logo with transparency can typically convert to a lossless WebP at ~25% the byte size, with the same pixels.
• Hosting and CDN savings — Smaller bytes mean lower egress costs on Cloudflare, Cloudfront, Fastly, or S3 transfer, and faster cache fills on origin servers. Sites pushing terabytes of image traffic see meaningful monthly savings.
• Mobile data and battery — Cellular users on metered plans download less; phones and tablets decode fewer bytes, finishing render sooner and dropping the radio out of high-power mode.
• Future-proofing — WebP is the lingua franca between legacy JPEG and newer AVIF; many CMSes (WordPress 5.8+, Drupal, Ghost) accept WebP uploads directly. See JPG to AVIF if you also want to test AVIF for hero images.

Frequently Asked Questions

How much smaller will my JPG be after converting to WebP?

For typical photographs at the default Very High preset, expect 25-30% smaller files than a quality-92 JPEG with no visible difference. Already-compressed JPEGs (q70 or lower) save less — sometimes only 10-15% — because the JPEG quantization has already discarded detail that WebP cannot magically recover. Re-encoding a heavily compressed JPEG to WebP saves bytes but does not improve quality.

Should I pick lossy or lossless WebP?

Use lossy (the default) for photos, banners, and any natural-content image — it is what WebP was designed for. Use lossless for screenshots, line art, logos with hard edges, and UI exports, where lossy compression can introduce ringing artifacts around text and edges. Lossless WebP is also a strong replacement for PNG; see PNG to WebP for that conversion.

Will WebP work in older browsers and email clients?

In browsers, ~96% of global traffic supports WebP today (caniuse.com). For the remaining sliver — mostly very old iOS, IE, and some embedded WebViews — use the HTML <picture> element: <picture><source srcset="image.webp" type="image/webp"><img src="image.jpg" alt="..."></picture>. Email clients are a different story: Gmail and Apple Mail render WebP, but several corporate webmail clients and older Outlook builds still do not, so HTML email should stick with JPEG.

Does Google Search index WebP images?

Yes. Google Images has indexed WebP since 2013 and explicitly recommends it in the Lighthouse "Serve images in next-gen formats" audit. WebP images appear in image search results, and improving LCP via smaller images is a documented Core Web Vitals factor.

Why didn't my file shrink as much as the 25-30% figure suggests?

Three common reasons. First, your source JPEG may already be heavily compressed (q60 or lower), so WebP has less redundancy to remove. Second, very small JPEGs (under 50 KB) have proportionally larger headers and per-block overhead, eroding the savings. Third, lossless WebP saves less than lossy — usually 20-25% versus PNG, but only modest savings over an already-compressed JPEG.

What's the difference between WebP and AVIF? Should I use AVIF instead?

AVIF (AV1 Image File Format) is newer and typically 15-25% smaller than WebP at the same visual quality. AVIF supports 10-12-bit HDR color, which WebP does not. The trade-offs: AVIF encoding is much slower (often 10-20× WebP), browser support is slightly behind (~94% vs ~96%), and CDN/CMS tooling is less mature. Many sites serve AVIF as the primary <picture> source with WebP as fallback. Try JPG to AVIF to compare.

Will EXIF metadata, color profile, and orientation transfer?

WebP supports embedded EXIF, XMP, and ICC color profiles. xconvert preserves the embedded ICC profile so colors remain accurate; EXIF orientation is applied to the pixels during conversion, so the WebP renders the correct way up even in viewers that ignore EXIF. If you need to strip metadata for privacy, that option is available in the advanced panel.

Can I convert JPGs in bulk and keep the original filenames?

Yes. Upload as many JPG, JPEG, or JFIF files as you need — the same quality preset, lossless setting, and resolution apply to all. Each output WebP keeps the source filename with the extension swapped (vacation.jpg becomes vacation.webp), so you can drop the batch into your CMS or build pipeline without renaming. To go the other direction later, use WebP to JPG.

Will converting to WebP help my PageSpeed Insights score?

Almost always yes. The "Serve images in next-gen formats" opportunity is one of the highest-scoring fixes on image-heavy pages, and Lighthouse only reports the savings if they exceed 8 KiB per image. Pair the WebP swap with proper width/height attributes, loading="lazy" on below-the-fold images, and an LCP image preload to capture the full Core Web Vitals benefit.
