Convert to WebP locally
Your browser decodes and re-encodes each image on this device. The HEIC engine (a small WebAssembly module) only loads when it's actually needed.

About jpg to webp converter
If you run a website or online store, JPG → WebP is the classic performance move: at the same visual quality, WebP is typically 25–35% smaller, pages load faster, and Core Web Vitals improve. Modern browsers all display WebP.
Quality is adjustable (40–100, default 90) so you can trade size against fidelity per image. Exporting WebP needs a Chromium-based browser (Chrome/Edge); Safari users should pick PNG or JPG.
Why convert in your browser
Truly private
Cloud converters upload every photo to their servers. Here, 0 bytes leave your device — there is no upload code path at all.
No installs
No Microsoft Store extensions, no desktop apps, no browser add-ons. Open the page and it just works.
Unlimited batches
Cloud tools cap free use (CloudConvert: 10 per day). Your own device has no such limit — convert a whole camera roll.
No queue
Nothing to upload means nothing to wait for. Large batches start converting immediately, two files at a time.
Frequently asked questions
How much smaller is WebP than JPG?
Typically 25–35% smaller at visually equal quality — sometimes more on simple graphics. At quality 80 the savings grow further and most photos still look clean.
Do all browsers display WebP?
Every current browser does, including Safari. Trouble only appears in outdated desktop software — which is exactly the case our WebP to JPG page solves.
Is the conversion still private for a whole image library?
Yes. Batches of any size run on your own machine — the images never leave the browser tab, so site visitors' photos or client assets stay private.
Are my photos uploaded to a server?
No — zero bytes are uploaded. Conversion runs entirely inside your browser using JavaScript and WebAssembly. There is no upload code path at all: you can even disconnect from the internet after the page loads and it still works.
Is there a limit on how many images I can convert?
No. Unlike cloud converters that cap you at 10–25 conversions per day or 200 files per batch, this tool converts as many files as you like, because your own device does the work.
Does it work on Windows, Mac, iPhone and Android?
Yes — any modern browser works (Chrome, Edge, Firefox, Safari). It is especially handy on Windows, where opening HEIC files normally requires codec extensions from the Microsoft Store.
