Is WebP smaller than JPG?

Yes. At comparable visual quality, WebP lossy files are typically 25–35% smaller than JPG. WebP also has a lossless mode that is around 25% smaller than PNG. The saving comes from a newer compression algorithm, and it is most noticeable on photographic images.

Is WebP better quality than JPG?

At the same file size, WebP generally looks slightly cleaner, with fewer blocking artifacts around edges and smoother gradients. At the same quality setting, the two are close enough that most viewers cannot tell them apart. WebP's bigger win is doing the same job in a smaller file.

Is WebP supported everywhere now?

For web browsers, essentially yes — Chrome, Edge, Firefox, Safari and Opera have supported WebP for years, and Safari added it in 2020. Support is weaker outside browsers: older desktop apps, some office suites, certain print workflows and a few content tools still cannot open WebP natively.

Should I use WebP on my website?

If your traffic is web browsers and you want faster pages, yes — smaller images mean faster loads, which helps both users and search ranking. The catch is that you should keep a JPG or PNG fallback for tools and services that don't read WebP, and for email or social sharing where JPG is still safest.

What are the downsides of WebP?

Out-of-browser compatibility is the main one: some desktop software, CMS uploaders, email clients and printing services reject or mishandle WebP. It also lacks proper CMYK support, so it is unsuitable for professional print. Metadata handling is weaker than JPG, and some tools strip EXIF data from WebP files.

Can I convert WebP back to JPG?

Yes. If a WebP file won't open in an app that expects JPG, drop it into a browser converter and export a JPG at the quality you need. This is the standard fix when a designer, printer or older program hands you a WebP you can't use.

WebP vs JPG: Is WebP Worth Switching To?

What WebP actually is

WebP is a format Google released in 2010, built from the VP8 video codec. It was designed for one job: make images on the web load faster. It does three things in a single container — lossy compression (competing with JPG), lossless compression (competing with PNG), and transparency and animation (which JPG cannot do at all). One extension, several jobs.

JPG has been the web's default since the mid-1990s and is understood by literally everything. So the real question isn't "which is technically better" — WebP wins on efficiency — but "is switching worth the compatibility trade-off in your situation".

File size: WebP's headline advantage

Lossy WebP vs JPG: typically 25–35% smaller at matching visual quality.
Lossless WebP vs PNG: roughly 25% smaller, with transparency preserved.
In practice: a 200 KB JPG hero image often becomes about 130–150 KB as WebP — a real difference on a page with dozens of images, especially on mobile connections.

Smaller images mean faster pages, and faster pages help both users and search rankings. For a content-heavy site, that saving compounds across every image on every page.

Quality: close, with an edge to WebP

At the same file size, WebP usually looks slightly cleaner than JPG — fewer blocky artifacts around sharp edges and smoother transitions in gradients and skies. At the same quality setting, the two are nearly indistinguishable in normal viewing. WebP's real advantage is delivering that quality in a smaller file, not in being dramatically better looking.

Compatibility: the reason JPG survives

Inside a browser, WebP is a solved problem. Chrome, Edge, Firefox, Opera and Safari (since 2020) all support it, so modern websites can serve WebP safely. Outside the browser it's messier:

Older versions of desktop apps, image editors and office suites may not open WebP natively.
Some CMS uploaders, email clients and social platforms convert or reject WebP.
Professional print workflows expect JPG, TIFF or PDF with CMYK — WebP has no proper CMYK support.
Metadata handling is weaker; some tools strip EXIF data from WebP files, which matters for photographers who embed copyright and camera info.

JPG's advantage is boring but decisive: it opens in every camera, phone, printer, browser and program made in the last quarter-century.

Should you switch? Three honest scenarios

Website owner worried about speed: yes, serve WebP and keep a JPG fallback. Most platforms (WordPress and many CDNs) do this automatically — you scale, upload a JPG, and they deliver WebP.
Photographer delivering to clients: usually no. Send JPGs. Clients expect them, print labs accept them, and the size saving doesn't matter for a delivery zip.
Everyday user sharing photos: no. Keep JPG for email, chat and social; convert the occasional WebP you receive into JPG if an app won't open it.

The tie-breaker: what happens after you export

Ask where the file is going. If it lives on a web page and is read by a browser, WebP is the better format. If it will be opened in unknown software, attached to an email, sent to a printer, or handed to someone on a USB stick, JPG is the safe default. The comparison is really about destination, not about the codec. Similar logic applies when choosing between PNG and JPG or deciding whether to keep HEIC versus JPEG.

Three flavours of WebP in one file

Lossy WebP — the JPG competitor, 25–35% smaller at matching quality.
Lossless WebP — the PNG competitor, around 25% smaller, preserving exact pixels and transparency.
Animated WebP — a GIF competitor, with true colour and much smaller files for simple animations.

That flexibility is why browsers favour it: one format covers photos, transparent graphics and simple animation, so a page can mostly drop GIF and PNG.

How websites serve it automatically

Most sites don't hand-manage WebP. A CMS plugin or a CDN reads the browser's Accept header and delivers WebP when it's supported, falling back to JPG or PNG otherwise. On the popular platforms this happens without you doing anything — you upload a JPG and the visitor receives a WebP. So you often get WebP's benefit without ever making a WebP file yourself, and without breaking the tools that still need JPG.

A concrete size example

Take a typical 1600-pixel-wide photo. As a JPG at quality 82 it might be 240 KB; as a lossy WebP at equivalent quality, roughly 160–175 KB. Multiply that across forty images on a product page and you've saved several megabytes of transfer — often the difference between a snappy page and one that makes people wait on a phone signal.

What about SEO and page speed?

Images are one of the largest parts of a typical web page, and search engines reward faster pages. Moving photographs from JPG to WebP — or letting a CDN handle it — trims that weight directly, which tends to improve Core Web Vitals metrics such as Largest Contentful Paint. For an image-heavy site, it's one of the highest-leverage changes available without touching the design or the copy.

How to convert WebP to JPG

The most common reason people search for this comparison is that they've received a WebP and something won't open it. The converter above fixes that in the browser: drop the .webp file in, leave JPG selected, set quality to taste, and download. Nothing is uploaded — the decoding runs locally on your device. Use the dedicated WebP to JPG converter, or the generic tool if your source is a RAW file or any other format.
