Free WebP Converter – Convert WebP to JPG, PNG, and Back Online
Need to convert a WebP file into a more compatible format — or the other way around? Our free online WebP converter handles both directions in one clean tool. WebP is a modern image format developed by Google that delivers 25–35% smaller file sizes than JPG at the same visual quality, which makes it ideal for fast-loading websites. But older software, some email clients, and certain social platforms still don't accept WebP. Whether you need to convert WebP to JPG for compatibility, WebP to PNG to preserve transparency, or turn your JPG and PNG images into WebP for a faster site, this tool does it all in your browser — no upload, no signup, no software to install.
Using the converter is simple. Drop one or more WebP, JPG, or PNG files into the zone, or click to browse and pick several at once. The tool automatically detects the first file's format and preselects the most useful output — WebP input defaults to JPG output, and JPG/PNG input defaults to WebP output. You can override this at any time using the output format dropdown, and the choice applies to the whole batch. Each file is then decoded, resized, and re-encoded in sequence, and every one appears as its own row with a thumbnail, its original size, its new file size, its pixel dimensions, and a per-file badge if transparency had to be flattened. When everything is ready, download each converted image individually or grab the whole batch as a single ZIP archive.
Why Use WebP?
WebP has become the go-to format for modern websites because it dramatically reduces file sizes without visible quality loss — meaning faster page loads, better SEO rankings, and lower bandwidth costs. Google's PageSpeed Insights and Lighthouse actively recommend serving images in WebP. If you run a blog, an online store, or any kind of content site, converting your images to WebP is one of the easiest performance wins available. And when you need to go the other way — because a client, platform, or legacy tool doesn't support WebP — this converter turns it into JPG or PNG in seconds. WebP also supports full transparency and animation, so it can replace both PNG and GIF in many situations, which is why browser support has grown to cover essentially every modern browser including Chrome, Edge, Firefox, Safari, and Opera.
Batch Convert an Entire Folder of Images
Developers, designers, and marketers often need to convert dozens or hundreds of images at once — an entire media library for a website migration, a folder of product photos, a design export from Figma, or a camera roll that needs to be shrunk for the web. Converting them one at a time is painfully slow. This tool accepts any mix of WebP, JPG, and PNG files in a single drop and processes the entire batch automatically. Each file is decoded independently, its native dimensions are detected, and any transparency is flagged with a visible badge so you know exactly which images needed a background fill. When everything is done, download each converted image separately or grab the whole set in one ZIP file named webp-converted.zip. Output format, quality, scale, background color, and target size all apply to the entire batch, and the live summary bar shows how many files are done and the total output size.
Private, Fast, and Completely Free
This tool runs entirely inside your browser using the HTML5 Canvas API. Your images never leave your device and are never uploaded to any server, so your photos, designs, and client work stay completely private. It works on Windows, Mac, Linux, Android, and iPhone, with no file size limits, no watermarks, and no signups. Whether you are a developer optimizing a website, a designer preparing assets, a blogger compressing images, or a casual user trying to open a WebP file in an older program, our WebP converter delivers professional results with a single click.
