PNG to WebP
Convert PNG images to WebP for much smaller files that still support transparent backgrounds.
Quick answer: Add your PNG files, leave the format on WebP, keep quality at 90 percent for graphics, convert, and check the edges of text and logos before using them.

How to use PNG to WebP
- Add the PNG filesChoose a batch of logos, icons, screenshots or illustrations. They stay on your device.
- Confirm WebP and keep quality highWebP is preselected. For graphics with text, stay near 90 percent so the edges stay clean.
- Resize if neededEnter a maximum width or height to avoid shipping a 3000-pixel graphic that displays at 600.
- Check and downloadOpen one converted file at full size before converting the rest, then download the files separately or all together as a ZIP.
About this tool
PNG is the usual format for logos, icons, screenshots and anything with a transparent background, and it is also one of the heaviest. WebP can store the same kind of image, including transparency, in a much smaller file. This page converts PNG to WebP in your browser so a page full of graphics loads faster.
Practical example: Convert a folder of 15 PNG icons, set quality to 90 percent, and verify that the transparent corners are still transparent on your site background.
Important limitation: Edges of small text can show slight softening at lower quality, and some software cannot open WebP. Metadata is not copied.
Conversion happens in this browser tab. The images are never uploaded. Read the privacy information.
How it works
Each PNG is decoded with its transparency, drawn onto a canvas and encoded again as WebP, keeping the alpha channel.
Real-world uses
- Making a website’s logos and graphics load faster
- Reducing the size of screenshots for documentation
- Preparing icon sets for an app or site
Converting graphics without damaging them
The big attraction is that WebP keeps the transparent areas of a PNG. Logos with soft shadows and icons on a colored page continue to work, unlike JPG. The savings are often large, particularly for screenshots and illustrations with large flat regions.
The trade-off is that WebP at normal quality settings is lossy, while PNG is not. For photographs and soft graphics this is invisible. For small text, thin lines and sharp edges, look closely: slight fringes or softening can appear. If you see them, raise the quality, and if that does not help, keep the PNG for that image.
Check where the image will be used. Modern browsers show WebP everywhere, but some email clients, content systems, social upload forms and desktop programs still expect PNG. Keep the PNG originals as masters and publish the WebP only where you know it works.
Reduce dimensions first. A 3000-pixel PNG shown at 600 pixels wastes most of its bytes. Using the maximum width or height box together with the format change usually produces the largest saving.
Tips for better results
- Raise quality for images with small text.
- Keep PNG masters for editing.
- Test transparency on the real page background.
Frequently asked questions
Does WebP keep the transparent background?
Yes. Unlike JPG, WebP supports transparency, so logos and icons keep their see-through areas.
Is the conversion lossless?
At the quality used here, WebP is lossy. It looks the same for most images, but check small text and thin lines at full size.
Can I use the WebP in an email or a Word document?
Many programs cannot display WebP. Keep a PNG copy for those uses.
How much smaller will it be?
It varies, but graphics often shrink dramatically. The result list shows the change for each file.
