How do I convert a PNG to WebP and keep transparency?
To convert a PNG to WebP, open FixDoks's PNG to WebP converter, add your files, choose a quality level and click Convert to WebP. WebP keeps transparent backgrounds while compressing far more efficiently than PNG, which shrinks product cut-outs, banners and screenshots for faster web pages. The conversion runs in your browser with no upload.

- Click Convert to WEBP and download each file, or all of them as a ZIP.
Smaller than PNG, still transparent
PNG is the usual format for images with transparency, but it can be heavy, especially for large graphics and photos with cut-out backgrounds. WebP supports transparency too and compresses much more efficiently. Converting product cut-outs, banners, illustrations and screenshots from PNG to WebP often makes them several times smaller.
Where to use the WebP files
- Website images, banners and product photos on online stores.
- Web apps and landing pages where page speed matters.
- Stickers and graphics for platforms that accept WebP.
Where to keep PNG
Office documents, some email clients, print shops and older design tools may not accept WebP. Keep the original PNG for those, or compress it with the PNG compressor instead.
Quality setting
For screenshots with text, use 90% or more so the letters stay sharp. For photos and illustrations, 75 to 85% gives a big saving with no visible difference. Each file shows its old and new size after conversion.
All files are converted in your browser. Add a whole folder of PNGs and download the WebP versions as a ZIP.
Product photos with cut-out backgrounds
Online stores often use product photos with the background removed, saved as PNG so they sit neatly on any page colour. These PNGs can easily be 1 to 3 MB each, which slows down category pages with dozens of products. Converting them to WebP keeps the cut-out edges and transparency while cutting the size substantially, so pages load faster on mobile data.
Keep your masters
Treat the WebP files as the web version and keep the original PNGs for editing and print. If you edit a WebP and save it again as lossy WebP repeatedly, small losses add up.
Resize as well
For the biggest saving, scale large graphics to their display size with the image resizer before converting. A banner shown at 1200 pixels wide does not need to be 4000 pixels wide.
Text-heavy graphics
Infographics and screenshots with lots of small text are sensitive to lossy compression. Use 90% or higher for them and inspect the letters. If they still look soft, the PNG compressor may be the better choice for those particular images, because it keeps edges perfectly crisp.
Batch conversion
Add all your PNGs at once; they are converted in turn and can be downloaded as one ZIP.
Most modern website builders and content systems accept WebP uploads directly, so you can replace heavy PNG images without changing any code.
