JPG to WebP Converter
Turn JPG photos into lighter WebP files for faster pages — in your browser, with a quality slider and per-file byte counts instead of advertising percentages. Your photos never leave your device, and their EXIF metadata (GPS included) is stripped on the way through.
Convert JPG files to WebP
Drop .jpg files and pick a quality. Each output is magic-byte-sniffed and re-decoded to prove it is a real WebP.
From the camera's format to the web's
JPG is where photographs are born — cameras and phones have written it for three decades — but it is no longer the most efficient way to ship those photographs over the network. WebP, built two decades later on video-codec prediction techniques, squeezes the same perceived quality into fewer bytes. When Lighthouse or PageSpeed tells you to "serve images in next-gen formats," this conversion is the step it means.
Second-generation compression, said out loud
Because your JPG is already lossy, re-encoding to WebP stacks a second approximation on the first. At the default quality of 85 the stack is visually benign for typical photos, but it is real: never treat a converted WebP as an archival master. The honest workflow is to keep the original JPG (or better, the camera RAW) and regard the WebP as a delivery copy. This page's rows report each file's true input and output sizes — and call out the cases where re-encoding gained nothing, so you can keep the original instead.
Stripped metadata, verified output
Two side effects of the canvas pipeline work in your favor. First, EXIF metadata does not survive: GPS coordinates, camera serial numbers, and timestamps are gone from the output — worth knowing both as a privacy feature for photos you publish and as a caveat for photographers who rely on copyright fields (they are stripped too). Second, verification is structural, not cosmetic: the output's magic bytes are sniffed to confirm genuine WebP — catching browsers that cannot encode it — and the file is re-decoded to confirm its dimensions before any download button appears.

Frequently asked questions
Why serve WebP instead of JPG on a website?
At a comparable visual level, WebP typically encodes photographs in noticeably fewer bytes than JPEG — that is why page-speed tools nag about it. Smaller images mean faster loads, better Core Web Vitals, and lower bandwidth bills.
Is converting JPG to WebP lossless?
No — and this matters. Your JPG is already lossy, and the WebP encoder compresses those decoded pixels again. It is a second generation of loss, kept minimal at high quality settings. Convert from your best-quality source when you can, and keep the originals.
What quality setting makes sense?
The default 85 is tuned for web delivery — visibly clean, meaningfully smaller. Push to 90+ for hero images you will inspect closely; drop to 70 for thumbnails. The per-file byte readout replaces guesswork with your own numbers.
Will the WebP ever be bigger than my JPG?
Occasionally, yes — especially for already heavily compressed JPGs. When that happens the tool says so on the row and recommends keeping the original. No fake savings claimed here.
Does EXIF data (location, camera info) carry over?
No. Canvas re-encoding strips EXIF entirely — GPS coordinates included, which is genuinely good before publishing photos online. Orientation is applied during decode, so the image itself stays upright; only the metadata is gone.
Do my photos leave my computer?
Never. Encoding runs in your browser tab, the site’s security policy blocks requests to other origins, and the methodology page shows how to watch the network panel stay empty while you convert.
Local processing: conversion and verification run entirely in your browser — no uploads, ever. Details and DIY verification steps on the methodology page.
