About the WebP Converter
Convert images to WebP to make them smaller, or from WebP to PNG and JPG when something you use will not open the file. Both directions are here because they are the same problem seen from two sides.
Converting to WebP typically saves 25 to 35 per cent against a JPEG at the same visual quality, and rather more against a PNG for photographic content. It supports transparency, so it replaces PNG for logos and JPEG for photographs without needing two formats. Every browser in use has supported it since 2020.
Converting from WebP is what you need when a desktop application, an older phone, a print workflow or a submission form refuses the file. Choose PNG to keep transparency and lose nothing further, or JPEG for a smaller file where transparency does not matter — the transparent areas are filled with a colour you choose rather than turning black.
Everything runs on your device using the browser's own image support, so nothing is uploaded. Where a browser cannot write WebP, the tool says so rather than silently handing back a PNG with the wrong extension.
How to use the WebP Converter
-
Choose the direction
WebP to make files smaller. PNG or JPG to open a WebP in something that will not accept it.
-
Add your files
Drop them onto the box or click to choose. Mixed formats in one batch are fine — they all convert to the same target.
-
Adjust the quality
WebP and JPEG expose a quality slider; PNG is lossless and ignores it. 85% is a good starting point for WebP.
-
Download
Each file reports the direction and the size change. Save them individually or all at once.
Frequently asked questions
Is WebP better than JPEG and PNG?
For the web, usually. It is typically 25 to 35 per cent smaller than a JPEG of the same visual quality, supports transparency like PNG, and every browser in use has supported it since 2020. Where it loses is outside the browser: plenty of desktop software, print workflows and older phones still cannot open it, which is why the reverse conversion exists.
Why will my software not open a WebP file?
Because WebP is a web format, and support outside browsers arrived late. Older versions of Photoshop, many print workflows, some content management systems and a range of phone galleries still refuse it. Converting to PNG loses nothing further and works everywhere; JPEG is smaller if transparency does not matter.
Is converting WebP to PNG lossless?
The conversion itself is — PNG stores every pixel of the decoded image exactly. But if the WebP was lossy, the detail it discarded is already gone, and PNG will store the result faithfully in a file that is often several times larger. It preserves what you have; it does not restore what was lost.
What quality should I use for WebP?
80 to 85 for most photographs, which is where WebP's advantage over JPEG is largest. Above 90 the saving narrows considerably. For graphics with flat colour and sharp edges, high quality settings matter more, because WebP's lossy mode softens hard edges much as JPEG does.
Are my images uploaded anywhere?
No. Decoding and encoding both happen in your browser using the image support it already has. Nothing is transmitted or stored, and the tool works offline once the page has loaded.
