JPG to WebP converter
Modernize JPEG photos into lighter WebP files for the web. Upload a .jpg, choose quality, and download a .webp that looks identical at roughly two-thirds the size — encoded privately on your device.
Convert JPG to WebP
WebP keeps transparency too, and 85% quality is the sweet spot for web photos.

WebP (. webp)
85–92% looks identical to the original for most photos. Applies to new conversions.
Private by design: conversion runs with canvas encoding on your device. Converting to JPEG flattens transparency onto a white background, and re-encoding always strips EXIF metadata.
Why WebP wins for the web
25–35% smaller files
Google's WebP encoder squeezes the same pixels into fewer bytes than JPEG at matched quality — free bandwidth savings on every pageview.
Faster page loads
Product photos and hero images are usually the heaviest page assets. WebP conversion is often the single biggest speed win available.
Transparency + photos in one format
Unlike JPG, WebP supports alpha transparency, so icons, logos, and cut-outs can live alongside photos in a single pipeline.
Universal browser support
All modern browsers render WebP natively — no plugins, no fallbacks needed for the vast majority of audiences.

Quality and file-size guide
WebP quality maps roughly 5 points below JPG: WebP at 80% looks like JPG at 85%, and WebP at 85% matches JPG at 90%. A 2MB JPG photo typically becomes a 1.2–1.4MB WebP at 85% with no visible change, and dropping to 80% pushes it near 1MB for thumbnails and decorative images. Start at 85% for anything prominent — hero images, product photos, portfolio work — and reserve 75–80% for avatars and below-the-fold decoration. Because conversion re-encodes pixels, always convert from the highest-quality original you have, not from an already recompressed copy.
Frequently asked questions
Why convert JPG to WebP?
WebP uses a more modern encoder than JPEG, so the same photo is typically 25–35% smaller at equal visual quality. Smaller images mean faster pages, lower bandwidth bills, and better Core Web Vitals scores.
Do all browsers support WebP?
Yes, effectively: every current version of Chrome, Edge, Firefox, Safari, and Opera displays WebP. Only very old browsers (pre-2020) lack support, so keep a JPG fallback if that audience matters to you.
What quality should I use?
WebP at 80–85% matches an 85–90% JPEG visually while staying smaller. Start at 85% for hero images and product photos, 75–80% for thumbnails and decorative images.
Is my photo uploaded to a server?
No. Encoding runs locally via the canvas API in your browser. Nothing is uploaded, no account is required, and EXIF metadata is stripped from the output automatically.
Can I convert in bulk or keep the original filename?
Drop up to 10 files into the tool above — they are converted one after another on your device, and each download keeps its original filename with only the extension changed (photo.jpg becomes photo.webp). With 2 or more done, a Download-all-as-ZIP button appears. Everything runs locally with no upload queue, so a batch takes seconds.
Should I replace all my site images with WebP?
For photos, hero images, and thumbnails — yes. WebP at 80–85% looks identical to JPG at 85–90% while weighing a third less, which directly improves Largest Contentful Paint. Keep PNG only for images that need lossless edges or transparency with legacy support, and keep a JPG fallback only if you serve visitors on browsers older than 2020.
