Convert images to WebP, in your own browser.
Drop in JPG, PNG, GIF, AVIF or ICO, set the quality, and take WebP back out. Feed it a WebP and you get a PNG. Nothing is uploaded — the conversion happens on your machine and the files never leave it.
FUEiNT Technologies is a software studio in Coimbatore, India, building custom software since 2014. This WebP converter is one of the small tools we built for our own client work and publish free: it runs entirely in your browser, and asks for no account and no email address.
No account, no address, no watermark and no daily limit. There is no sign-up step because there is nothing to sign up to.
The conversion runs in the page itself. Your images never reach a server of ours, because there is no server of ours for them to reach.
Convert as many files as you like at once, download them one by one, or take the whole set as a single ZIP.
JPG, PNG, GIF, AVIF and ICO go in and come out as WebP. Put a WebP in and it comes out as PNG.
Convert your images
How it works
- Choose your files
Drop images onto the panel, or click it and pick them. JPG, PNG, GIF, AVIF and ICO all work — as does anything else your browser can decode as an image.
- Set the quality
The slider is the WebP quality, 0 to 100, and it starts at 50. Lower makes a smaller file and more visible artefacts; around 70 to 80 is where most photographs stop losing anything you can see.
- Convert
Each image is drawn onto a canvas at its own natural size and re-encoded there. Nothing is resized, cropped or renamed beyond the file extension.
- Download
Take each file from the link under its preview. Convert more than one and you can take the whole set as a ZIP, built in the page like everything else here.
The background, in plain words.
What a WebP file is
WebP is an image format Google published in 2010, and every current browser reads it. It does lossy compression like JPEG and lossless compression like PNG, and it supports transparency and animation in both modes — which is the part neither JPEG nor GIF manages on its own.
Google’s own published figures put a lossy WebP at 25–34% smaller than a JPEG of comparable quality, and a lossless WebP at around 26% smaller than the equivalent PNG. On a product page carrying twenty photographs, that difference decides whether the page appears on a mid-range phone on a weak connection or whether the shopper leaves first.
Where your files go
Nowhere. The page reads the file you picked, draws it to a canvas element and asks the browser to re-encode it. The ZIP is assembled in the page too. No request is made and no copy is kept, here or anywhere else.
You do not have to take our word for it. Open your browser’s network panel, convert a file, and watch that nothing is sent. Or disconnect from the internet once the page has loaded — the converter carries on working.
How to open a WebP file
Chrome, Firefox, Edge and Safari all display WebP directly, so double-clicking one usually just works. For editing, GIMP, Photopea, Paint, Pixelmator and Corel PaintShop Pro all open them, and Photoshop has read WebP without a plugin since version 23.2 in 2022.
Older Photoshop versions, IrfanView and the long-retired Windows Photo Viewer still need a plugin. If a program refuses a WebP outright, put the file through this converter first and it will come back as a PNG that everything opens.
Why we publish it
We convert images to WebP on nearly every site we build, and we were not willing to upload a client’s unreleased artwork to somebody else’s server to do it. So the converter runs in the browser, and since it costs us nothing to run, it is free and it stays free.
Questions we are actually asked.
Is it actually free?
Yes. No account, no email address, no watermark and no limit on how many files you put through it. Nothing on this page is a trial of anything.
Do you keep my images?
We never receive them. The conversion happens inside your browser, so there is no upload, no copy on a server and nothing for us to keep or delete.
Which formats can I put in?
JPG, PNG, GIF, AVIF and ICO are the ones we test. In practice anything your browser can decode as an image will convert, because the browser does the decoding.
What happens if I feed it a WebP?
It converts the other way and gives you a PNG. The quality slider has no effect on that path — PNG is lossless, so the setting is ignored.
Why is my converted file larger than the original?
Usually one of two reasons. Re-encoding an already-compressed JPEG at a high quality setting can cost more bytes than it saves, so drop the slider. And a WebP converted back to PNG is almost always larger, because PNG keeps every pixel exactly.
Does it handle animated GIFs?
Only the first frame. Each image is drawn once to a canvas, so an animated GIF comes out as a still WebP. For animated WebP you want a command-line tool such as gif2webp.
Is there a file-size or batch limit?
None that we impose. The real limit is your own device: the whole set is held in the page while it converts, so several hundred large photographs will struggle on a phone and be fine on a laptop.
Does it work offline?
Once the page has loaded, yes. Nothing after that point needs a connection.
Other things here that are free.
Images are usually the cheapest thing to fix on a slow site.
They are rarely the only one. Send us the URL and what it feels like on a phone, and a senior engineer will write back with what we would fix first and what it would be worth.
