How to use the PNG to WebP tool
- 1
Add your PNG files
Drop in logos, screenshots, illustrations or cut-out product images, or choose them from your device.
- 2
Fine-tune the quality
WebP is preselected and transparent areas are kept automatically. Use the quality slider to balance sharpness and size.
- 3
Download the WebPs
Save them one by one or as a ZIP, ready to upload to your site.
Why use KBSnap’s Image Converter?
Transparency kept
No need to flatten images onto white – see-through backgrounds survive the conversion.
Lighter than PNG
WebP is usually much smaller than PNG for screenshots, photo-like graphics and cut-outs.
Quality control
Raise the slider for crisp text and logos, lower it for bigger savings.
Batch conversion
Convert a whole folder of graphics in one go and download a ZIP.
Private
Unreleased designs and client assets stay on your device.
Why convert PNG to WebP?
PNG is perfect for editing because it's lossless, but that same precision makes it heavy on a web page – particularly for screenshots, illustrations with gradients and product photos on transparent backgrounds. The traditional way to shrink them was converting to JPG, which throws the transparency away.
WebP keeps the transparency, so you get smaller files without flattening anything onto a white box. Typical uses:
- Online shop product images cut out on a transparent background.
- Logos, icons and illustrations used across a website.
- Blog and help-centre screenshots that make articles slow to load.
- Banners and interface graphics in web apps.
PNG vs WebP vs JPG for graphics
| Feature | PNG | WebP | JPG |
|---|---|---|---|
| Transparency | Yes | Yes | No |
| Compression | Lossless | Set by the quality slider | Lossy |
| File size | Largest | Small | Small |
| Support | Universal | All modern browsers, most newer apps | Universal |
| Best for | Master copies and editing | Publishing graphics on the web | Photos without transparency |
Getting crisp results with text and logos
WebP output is encoded with the quality you choose, so at lower settings you may notice faint smudges around small text, thin lines and hard-edged shapes. Photos and soft cut-outs hide this well; screenshots and logos show it first.
- Use a higher quality for screenshots with small text, line art and logos.
- Use a moderate quality for photos and product cut-outs – the savings are bigger and artefacts are hard to see.
- View the result at 100% zoom before publishing.
If a simple graphic still looks better as PNG, keep it as PNG and shrink it with Compress Image, which reduces the number of colours while keeping transparency.
What to expect for different PNGs
How much you save depends on what the PNG contains:
| PNG content | Typical result as WebP | Suggested quality |
|---|---|---|
| Product photo on a transparent background | Much smaller | Moderate |
| App or website screenshot | Much smaller | High, to keep text sharp |
| Illustration with gradients | Noticeably smaller | Moderate to high |
| Flat logo or icon with few colours | Small saving, sometimes none | High – or keep the PNG |
Because results vary, convert a few samples first and compare the downloaded files with the originals – both the size and how they look – before converting a whole library.
When to keep the PNG
Keep the original PNG as your master copy for future edits – converting back from WebP can't restore detail that compression removed. PNG is also the safer choice for documents, presentations, email and upload forms that don't list WebP as an accepted type.
Some website and shop platforms already convert uploaded images to modern formats automatically, so check your platform's settings before converting a large library by hand.
Resize oversized graphics to the size they'll actually be displayed with the Image Resizer before converting. And for photos with no transparency at all, JPG to WebP or PNG to JPG may be the better fit.
