WEBP Converter
FileFlip converts WEBP files into 61 other formats entirely inside your browser, using ImageMagick, MuPDF and Pandoc compiled to WebAssembly. The WEBP file is never uploaded to a server: it is read off your disk, converted on your own machine, and saved back by the browser. There is no file-size limit and no account to create.
How do I convert a WEBP file?#
- Drop your WEBP file onto the converter at the top of this page, or click it to pick one from your computer.
- Choose the format you want out of it. FileFlip downloads the engine that conversion needs, once, and your browser caches it.
- Conversion starts the moment you pick the format, and the result is yours to download. The work happens in this tab, so nothing is uploaded and nothing is queued.
Is it safe to convert WEBP files online?#
Yes, because nothing is uploaded. FileFlip converts WEBP files inside the browser tab you already have open, using WebAssembly builds of the same engines a desktop converter would install. Your file is read from your own disk into the page's memory, and no request carrying it is ever made.
You do not have to take that on trust. Open your browser's network panel, run a conversion, and you will see the engine come down and your file go nowhere. There is no upload, no server-side copy, no retention window, and no account tied to what you converted.
How FileFlip works lists every engine, its version and its download size, and shows how to check for yourself that nothing leaves your machine.

What is a WEBP file?#
A WebP file holds a still or animated image compressed with Google's WebP codec, built as a single format to undercut JPEG, PNG, and GIF on file size at comparable quality.
Use WebP for images on the web: it's the general-purpose replacement for JPEG, PNG, and GIF now that every major browser renders it natively.
Convert WebP to JPEG or PNG when the file needs to open in older software, a print workflow, or an app that still doesn't recognize the .webp extension.
The WEBP file format reference covers the specification, the programs that open one, and what each conversion keeps or drops.
WEBP questions people ask#
What is a WebP file?
A WebP file is an image saved with Google's WebP codec, which can encode a picture either losslessly or lossily and supports both transparency and animation in the same format. Google introduced it in 2010 to replace JPEG, PNG, and GIF with one format that produces smaller files at comparable quality.
Can WebP animate like a GIF?
Yes, WebP supports animation through its extended file format, which stores a sequence of frames the way GIF does but compresses them far more efficiently. Google has measured roughly 64% smaller files converting animated GIFs to WebP, and every major browser has supported animated WebP since 2020.
Why won't my WebP file open in some programs?
WebP is newer than JPEG or PNG, so support arrived later in some software. Windows Photos only added native WebP support in 2023, and Adobe Photoshop only added it in 2022, so anything older needs a plugin or a converted copy. Converting the file to JPEG or PNG sidesteps the issue for software that never added support at all.
Is WebP lossy or lossless?
WebP can be either, chosen at the time the file is encoded. Lossy WebP works like JPEG, discarding detail to shrink the file, while lossless WebP works like PNG, preserving every pixel exactly. A single format offering both is something neither JPEG nor PNG does on its own.
Does WebP support transparency?
Yes, WebP supports an alpha channel for transparency in both its lossy and lossless modes. That's an advantage over JPEG, which has no transparency support at all, and it's one reason WebP can replace PNG for graphics as well as JPEG for photos.
