JPG to WebP, Lighter Web Images in Seconds

Make any JPEG lighter as WebP and lose about a third of the weight, with a lone photo rebuilt on your device and batches handled on our server.

or drop the image here

Quick answer

Change a JPG into a WebP and watch the file shrink. Pick a JPEG, and for a single photo your browser rebuilds it as WebP and offers the download a moment later, with that one image handled on your own machine and nothing sent out. Both formats are lossy, so this is a lossy-to-lossy rebuild, and at the careful quality Araluma uses the eye cannot pick the two apart on a photo. Expect the result to weigh roughly a quarter to a third less than the original, the band Google quotes for its own WebP format, and many photos do even better. We measured a 17 KB JPEG shrinking to 7.3 KB. Lighter pictures paint faster, which lifts your Largest Contentful Paint score. Got a folder to clear? Drop several JPEGs together and they travel to our server to be rebuilt as a batch, where the download link clears in about 2 hours.

Turning a JPG into a WebP, step by step

Turning a JPG into a WebP, step by step

Drop a JPEG into the box, or tap it open and choose a file. Conversion kicks off as soon as the file is in. Nothing else to click, no line to stand in. The rebuild into WebP runs on your own machine inside the browser. Once it lands, the stats row sets the old weight beside the new one, so the cut is obvious at a glance. Hit Download to keep the WebP, which holds the original name under a fresh ending. Want a second photo? Drop it over the first and the page swaps the result without reloading. A photo straight off a phone is usually done before you have finished reading this line, comfortably inside a second.

What makes a WebP lighter than the JPG

What makes a WebP lighter than the JPG

Both formats discard detail to save space, but WebP spends its budget more wisely at any quality you choose. Google pegs the usual gain at a quarter to a third over JPEG, and packed real-world shots routinely run past that. Our own numbers agree. A 17 KB JPEG at 1024 by 768 fell to 7.3 KB, while a 116 KB shot at 3840 by 2160 dropped to 32 KB. Lighter pictures finish painting sooner, which trims your Largest Contentful Paint, the timing signal Google folds into ranking. WebP also costs nobody a licence fee, which is the reason every large CDN reaches for it by default and every recent browser reads it with no plugin and no download standing in the way.

Picking WebP over JPG, and the times you should not

Picking WebP over JPG, and the times you should not

Lean on WebP for anything headed to a page you run: banners, product shots, article art, gallery tiles, and the share cards your own domain serves up. Every recent browser reads it, which is over 97 percent of traffic in 2026, and Safari has joined since version 14. Hold onto JPG when the file has to travel somewhere that still expects JPEG, like an email attachment, a print run, a dated photo editor, a marketplace upload box, or a service that flips WebP back to JPEG behind the scenes anyway. Where the picture ends up settles it, not where it began. If you own the place it is served and the readers run current browsers, WebP is the smarter call almost every time.

Quality and that second round of loss

Quality and that second round of loss

The JPEG you started with already gave up detail, so making a WebP from it adds a second round of loss on top. On paper, the wear could build. In real use, at the near-lossless level here, the photo reads as the source at any sensible viewing distance. For the cleanest outcome, begin from the strongest JPEG you hold, an original off the camera and not a copy that has already bounced through a messaging app or a CDN squeeze. Every pass takes a little more. This build runs at one steady quality with no slider, which keeps results predictable and stops anyone from grinding a photo down further than it ever needed to go.

Where your picture is handled

Where your picture is handled

Rebuilding one picture runs in your browser, on your own hardware, with nothing sent out. To see it for yourself, open DevTools, move to the Network panel, and run a single conversion. Not one image request leaves the page. When you rebuild several at once, the files travel to our server so they can be processed together, and the download link clears in about 2 hours. There is no long-term copy kept and nothing studied about what the files hold, whichever path you take. The result is yours to keep either way.

Where WebP is read in 2026

Where WebP is read in 2026

Across the browser world today, WebP reading is close to universal. Chrome has decoded it for over a decade, since version 17 in 2012. Firefox joined at version 65 and Safari at version 14 on iOS, then version 16 once you reach macOS Ventura. Edge and Opera both take it without help. What is left out is a thin band, mainly Internet Explorer 11 and Safari 13, whose combined share barely registers now. Day to day, that means you can publish WebP and move on. Should you really need to cover something ancient, an HTML picture element can name both a WebP and a JPG so each browser reaches for what it understands. Outside the browser, for mailboxes, shared drives, and the printer, JPG remains the calmer choice.

How it works

  1. Choose your JPG

    Tap the box open or pull one or more JPEGs into it from your desktop. The run begins by itself the second the files are in, with nothing to press first.

  2. Let the rebuild happen

    For a single photo your browser rebuilds it as WebP in its own memory, with nothing to send out. A phone shot is done comfortably inside a second.

  3. Glance at the weight cut

    Once the WebP is ready, the stats row lines up the old JPEG weight against the new one, so the saving is plain before you keep it.

  4. Keep the WebP

    Tap Download to store the result. The name carries over and the ending becomes .webp on its own, so there is nothing to rename by hand.

Frequently asked questions

Why move from JPG to WebP?

Smaller files are the short answer. At a matching quality, WebP weighs less than JPEG, so pages paint quicker and your Core Web Vitals improve. Google's published band runs a quarter to a third under JPEG, and dense photos often clear that. Anyone maintaining a library of site images gains twice over: a lighter bandwidth bill, and a Largest Contentful Paint that can climb directly, since that timing feeds Search ranking.

Is this a lossless conversion?

It is not. Both WebP and JPEG throw away data, so going across stacks a second lossy pass onto the first. At the near-lossless level here, that pass hides on a photo viewed at any normal distance. Want something truly lossless? PNG is the format for that. And steer clear of any tool advertising a lossless JPEG to WebP path, because WebP-lossless is its own separate mode for PNG-style art, never for photographs.

How much lighter does a WebP run?

Our numbers tell the story. A 17 KB JPEG at 1024 by 768 dropped to 7.3 KB, and a heavier 116 KB shot at 3840 by 2160 fell to 32 KB. Google frames the usual gain as a quarter to a third under JPEG at equal quality. The exception is the very small, already-crushed image, a thumbnail beneath 10 KB say, which has little left to give because it already brushes the encoder's floor.

Can WebP hold transparency?

Yes. WebP carries a full alpha channel while JPEG carries none, one reason it suits web graphics. For a JPG to WebP run, though, there is no transparency around to hold, since the source JPEG is solid from edge to edge. If your image began as a PNG with transparency and you want that kept in WebP, convert straight from the PNG rather than from a flattened JPEG sitting in the middle of the chain.

Does my picture get uploaded?

It depends on how many. Converting one picture runs entirely in your browser on your own device, so no image request leaves the page, which you can confirm in the Network panel of DevTools. Converting several together sends them to our server so they can be rebuilt as a batch, and the download link clears in about 2 hours. Nothing is stored for the long term and nothing is collected about what the files hold, either way.

Can I convert a batch of JPGs together?

Yes. Drop two or more JPEGs and they are rebuilt together, then come back as one download. To do that the files travel to our server, which packs the WebP results into a single archive and hands you one link that clears in about 2 hours. A single JPEG still rebuilds right in your browser with nothing sent out.

The details

Notes from the team on craft, formats, and the small decisions behind a good round crop.

How a single JPG becomes a WebP, and what shifts for several
Drop one JPEG and here is the chain inside your browser. The file is read into memory, the compressed bytes are turned back into raw pixels by the built-in JPEG reader, those pixels are laid onto a working surface off-screen, and the platform is asked to emit them once more in WebP form. What returns to you is a fresh WebP, offered as a download, with every link of that chain living on your own machine so nothing touches the network for a single image. Our 17 KB JPEG at 1024 by 768 closed the loop in roughly 54 milliseconds on Chromium, while a 116 KB photo at 3840 by 2160 wanted about 550 milliseconds. When you hand over several at once the shape changes: the files travel to our server, get rebuilt together, and come back as one archive whose link clears in about 2 hours.
EXIF and metadata across the conversion
A JPEG can haul a real load of metadata. EXIF records the camera, the GPS spot, shutter speed, and which way is up. IPTC fields carry the credit line and caption. XMP packets keep a log of edits, and ICC profiles hold the colour management. The conversion here preserves not a single one of them. What lands is a tidy WebP holding only the visible picture. That is the ordinary outcome for any tool that paints through the browser, identical across Chromium, Firefox, and WebKit. For most publishing it counts as a win, shaving a few bytes while keeping GPS and personal data out of a public image. Where one field truly has to survive, usually orientation, rotate the photo first or pass it through a metadata-aware editor beforehand. Do not rely on this tool for archival work that needs the original metadata intact.
WebP against JPEG: a different compression idea
JPEG carves an image into 8 by 8 squares and runs a Discrete Cosine Transform, turning spatial detail into frequencies, then leans harder on the high ones. WebP takes a prediction idea from VP8 video: each square is guessed from neighbours already decoded, and only the leftover gap is stored. That tends to leave fewer blocky marks at the same weight, above all on gentle gradients and skin where JPEG's grid can surface as a visible quilt. On a photo at high quality, past q80, the eye seldom spots the gap, yet the weight saving holds firm. Down at lower quality, under q60, WebP pulls further ahead and the artifacts shift character: WebP melts into a soft blur while JPEG flashes its blocks. Neither leads on every shot, and dense textures like foliage can come out close to even in both.
Core Web Vitals and the reason to switch
LCP, short for Largest Contentful Paint, times how quickly the largest visible element settles into view. On a typical marketing page that element is the hero photo, and Google has stated plainly that Core Web Vitals shape Search ranking. A 300 KB hero JPEG can shove LCP past 2.5 seconds on a mid-range phone connection. Re-saved as a roughly 180 KB WebP, the same hero often slides LCP back under that line with nothing else touched. Now multiply: a page with six JPEGs adding up to 1.2 MB can drop 300 to 400 KB by going WebP, which speeds the first real paint over slow links. CDNs that negotiate content even hand WebP to compatible browsers by themselves, so once the originals exist there is no per-image chore left.
WebP support in 2026 and the thin gaps
Tallying support in 2026, WebP decodes from Chrome 17, Firefox 65, Edge 18, Opera 11.10, and Safari 14 on iOS 14 and macOS Big Sur. By caniuse.com the combined decode reach passes 97 percent of browser traffic. What remains is mostly Internet Explorer 11, Safari 13 on Catalina, and a thin trail of very old Android browsers. For nearly every public project, handing WebP to all comers is safe. Should total reach be the aim, an HTML picture element names a WebP source next to a JPEG fallback in one tag, and the browser claims whichever it can read. CDNs carrying image optimisation read the Accept header and settle the format on their own, sparing you any browser-by-browser checking done by hand.
The times WebP is the wrong pick
For modern web delivery WebP is right, yet a few well-worn cases call for something else. The print room wants CMYK, which WebP does not carry, leaving JPEG and TIFF as the press standards. Mail is uneven, with Gmail and Apple Mail rendering WebP while Outlook on Windows declines. Sharing services split too: Drive, Dropbox, and GitHub display it, but plenty of social platforms, stock libraries, and shop systems quietly flip incoming images back to JPEG, voiding the WebP step. Editors stay patchy, since Lightroom, Capture One, and Affinity Photo open WebP while many plugins and export presets still reach for JPEG by habit. Whenever images pass through third-party systems beyond your control, keep a JPEG master and convert to WebP only at the final delivery step.
