The right choice for logos, icons and graphics
Converting WEBP to JPG works well for photos, but it fills transparent areas with white. That's a problem when the image is a logo you want to place on a colored background, an icon for a presentation, a sticker, or a product cut-out for a flyer. PNG keeps the transparency, so the image sits cleanly on top of whatever you put behind it.
PNG also keeps sharp edges and small text exactly as they are, which makes it a good home for diagrams, charts and screenshots that were saved from a website as WEBP.
Works where WEBP doesn't
PNG is supported by practically every image editor, design tool, office suite and presentation app, including older versions that can't open WEBP at all. If a program shows an error or an empty frame when you insert a WEBP file, the PNG version will usually just work.
It's also a safer format for editing. Because PNG is lossless, you can open it, change it and save it again as many times as you need without adding compression artifacts.
About file size
A PNG is often heavier than the WEBP it came from, especially with photos. That's the price of lossless quality. For graphics and images with few colors the difference is usually small, and “Compress image” can make the PNG lighter by reducing it to a palette of up to 256 colors.
If your image is a photo with no transparency and you just need it to open anywhere, WEBP to JPG will usually give you a lighter file.
Your files stay on your device
The conversion runs in your browser. Your WEBP images aren't uploaded and aren't stored, and there's no account or email to give. ConvertirDocs is 100% free and has no limit on how many images you convert.
EXIF data is removed from the PNG, including any GPS location, so the file you share carries only the image.
Common cases
A client sends a logo pulled from their website and it arrives as WEBP. You need an icon for a slide deck, but the presentation app won't insert WEBP. You're preparing a flyer and want a product cut-out without a white box around it. You saved a chart from an online article and want to paste it into a report. Converting to PNG keeps the edges and the transparent areas intact, so each of these images is ready for the next step.
