Convert Any Image to WEBP in Your Browser for Free
WEBP started as a Google experiment in 2010 and quietly became the default image format of the modern web. Every current browser supports it, content delivery networks negotiate it automatically, and page speed guidance from Google keeps pointing site owners toward it. The reason is simple arithmetic: WEBP photographs are usually 25 to 35 percent smaller than an equivalent JPG, and lossless WEBP beats PNG by roughly 26 percent, which means faster pages, lower bandwidth bills, and better Core Web Vitals scores.
The problem is that the rest of your workflow often speaks a different format. Cameras and iPhones produce JPG and HEIC, designers hand over PNG and SVG, print and scanning pipelines output TIFF, and older archives are full of BMP and GIF. This converter accepts all of them and writes WEBP, so one tool covers the whole route in. It also runs the other direction, turning WEBP back into JPG, PNG, BMP, ICO, or GIF when a platform, editor, or upload form refuses the modern format.
Batch work is where the time actually goes. A product catalogue, a documentation set, or a year of blog images can mean hundreds of files, and converting them one at a time is not realistic. Add a whole folder here instead, set the output format and quality once, and convert everything in a single pass. Results can be downloaded individually or collected into one ZIP archive, and the maximum width field shrinks oversized originals while the aspect ratio is preserved.
Quality control matters because WEBP compression is lossy by default. The slider runs from 10 to 100 and defaults to 92, which lands close to the original for most photographs while still cutting real weight. Push it higher for text-heavy graphics and product shots with fine detail, or lower it when a page mainly needs small thumbnails. Transparent PNG and SVG sources keep their alpha channel in the WEBP output, while JPG output flattens transparency onto a background color you choose.
Everything happens on your own device. Files are decoded and re-encoded through the browser’s own imaging code and the Canvas API, so nothing is uploaded, stored, or scanned anywhere along the way, which is worth knowing when the images are unreleased designs, client photographs, or internal screenshots. There is no account to create, no watermark added to your files, no daily quota, and no software to install. Add your images, choose WEBP, and convert.

FAQ
Frequently Asked Questions
WEBP is an image format Google released in 2010. It supports lossy and lossless compression, transparency, and animation, and usually produces files 25 to 35 percent smaller than an equivalent JPG at the same visual quality.
JPG, JPEG, PNG, GIF, BMP, TIFF, SVG and HEIC or HEIF photos all work as input. HEIC is decoded locally in the browser, and TIFF and SVG are handled the same way, with no plugin required.
Yes. Add as many files as you need in one go, set the output format and quality once, then convert the whole queue in a single pass and download the finished files together in one ZIP archive.
Yes. Both PNG and WEBP carry a full alpha channel, so transparent logos, icons, and cut-out product shots keep their see-through background. Check the result against your intended page background before publishing it.
Usually yes. Photographs from JPG typically shrink by 25 to 35 percent, and PNG graphics by around a quarter, though images that are already heavily compressed may barely change. The quality slider decides where the balance lands.
Yes. This page handles both directions. Choose WEBP to compress images for the web, or load WEBP files and export them as JPG, PNG, BMP, ICO, or GIF whenever a platform, editor, or upload form will not accept the modern format.
There is no daily quota, watermark, or account requirement. The practical ceiling is your own device memory, because every file is decoded and encoded locally, so very large batches are simply processed one file at a time.
No. Decoding and encoding both run in your browser through the Canvas API, so files never leave your device and are never stored, logged, or analysed. You can verify this by watching the network tab while a conversion runs.
Every current version of Chrome, Edge, Firefox, and Safari supports WEBP, and Safari has done so since 2020. That covers the overwhelming majority of web traffic, though older desktop software may still need PNG or JPG instead.
Neither. The converter runs in an ordinary browser tab on desktop or mobile, with no registration, no email address, no plugin, and no app to download. Open the page, add a file, and the first conversion takes a few seconds.
