Use the PNG to WebP Converter when you want a smaller file for icons, logos, or graphics while keeping transparency. Select the PNG, process it locally in your browser, and download the WebP copy.
Why PNG to WebP Is Different From PNG to JPG
Unlike converting to JPG, converting a PNG to WebP keeps the alpha channel, so transparent backgrounds carry over instead of being filled in.
- Transparent areas in the PNG stay transparent in the WebP output.
- Lossless WebP suits logos, icons, and text-heavy graphics that need sharp edges.
- Lossy WebP suits photo-like PNGs where a bit of compression is an acceptable trade for a much smaller file.
When to Convert and When to Keep PNG
WebP is usually the smaller option, but a few situations still call for keeping the original PNG.
- Convert a whole icon or graphic library to WebP to speed up a website's load time.
- Keep PNG if a specific platform or older tool only validates uploads by PNG file signature.
- Pixel dimensions and visible transparency detail stay the same either way; only the format and compression change.
Resize, Crop, or Compress?
Most image upload problems fall into one of three jobs. Choose the tool based on the rule shown by the website or app.
- Use Image Resizer when the requirement mentions width, height, pixels, dimensions, or scale.
- Use Image Cropper when the subject needs better framing, a square crop, or background edges removed.
- Use Compress Image to 2MB, Compress Image to 1MB, or Compress Image to 500KB when the requirement mentions KB, MB, file size, or maximum upload size.

Frequently Asked Questions
Does converting PNG to WebP keep transparency?
Yes, unlike converting to JPG, WebP supports an alpha channel, so transparent areas in the PNG stay transparent in the WebP output.
Why convert a PNG logo or icon to WebP?
WebP can produce a noticeably smaller file than PNG for the same image, especially in lossless mode, which helps pages with many icons or graphics load faster without giving up transparency.
Should I use lossy or lossless WebP for a PNG with sharp edges or text?
Lossless WebP is usually the safer choice for logos, icons, and text-heavy graphics, since lossy compression can introduce soft edges or artifacts around sharp lines that a PNG originally kept crisp.
How much smaller is WebP compared to PNG for the same image?
Savings vary a lot. Simple graphics with few colors may only shrink modestly, while complex, photo-like PNGs can shrink substantially more, sometimes by half or more.
Will converting to WebP change how my transparent image looks?
Visually it should look the same in a browser that supports WebP, since the point of choosing WebP here is to preserve the visible image and transparency while changing only the underlying file format and compression.
Can I convert an animated PNG to an animated WebP?
WebP does support animation, so an animated source can carry that over if the conversion tool preserves multiple frames, but a simple single-image PNG-to-WebP conversion produces a static image either way.
Why do some website builders reject WebP images with transparency?
Some older or narrowly built upload systems check specifically for PNG file signatures or don't fully support WebP's alpha channel handling, so keep a PNG fallback if a platform behaves unexpectedly.
Does WebP support the same level of transparency detail as PNG?
Yes, both formats support a full range of alpha transparency values, not just fully transparent or fully opaque, so soft-edged transparency like shadows or fades should carry over correctly.
Will converting my PNG to WebP reduce its pixel dimensions?
No, only the file format and compression change; the width and height remain the same unless resized separately.
Can I batch convert a folder of PNG icons to WebP at once?
Yes, use the batch image converter if you have multiple PNG files that all need to become WebP, instead of converting them here one at a time.
Is there ever a reason to keep an image as PNG instead of converting to WebP?
Yes, if you need guaranteed compatibility with very old software, specific desktop publishing tools, or a platform that explicitly requires PNG uploads, keeping the original PNG avoids compatibility issues WebP could introduce there.
