PNG is the format people reach for when they need a transparent background, but it's an expensive way to store one — a lossless PNG of a photo-like image can be several times the size of the equivalent WebP. WebP supports the same alpha channel, so you keep the transparency and lose most of the bytes.
That combination is what makes WebP the standard choice for logos, icons, UI assets and product cut-outs on the web. A transparent PNG hero image weighing 800 KB routinely drops to well under 200 KB as a WebP with no visible difference.
Because WebP is lossy at the quality we use, keep your original PNG as the master copy for future editing and treat the WebP as the export. Everything runs in your browser — nothing is uploaded.
How to use the png to webp
- 1
Add your PNG images
Drag one or many PNGs into the box, or click to browse for them.
- 2
Convert to WebP
Each image is re-encoded as a WebP in your browser, alpha channel preserved.
- 3
Download
Save a single WebP, or a ZIP of every WebP if you converted a batch.
Keeping transparency, losing the weight
PNG is the format screenshots, logos and diagrams live in because it is lossless and supports transparent backgrounds — and it is heavy for exactly that reason. WebP offers both lossless compression and an alpha channel, in a file that is usually far smaller.
For a logo, an icon or a UI screenshot on a web page, that is close to a free win: the transparency survives, the sharp edges stay sharp, and the file drops substantially.
How much smaller?
Lossless WebP typically beats PNG by around 25–30% on the same image, and considerably more on screenshots and graphics with large areas of flat colour. Complex photographic content saved as PNG can shrink much further still, because it should not have been a PNG in the first place.
Transparency is preserved exactly, so nothing needs re-cutting after conversion.
When to keep the PNG
- Files other people will open
- Colleagues, clients and upload forms may not accept WebP. Send PNG.
- Print work
- Print pipelines are built around PNG, TIFF and JPG.
- Design source files
- Keep the PNG as the master and convert copies for the web.

Frequently asked questions
Does transparency survive the conversion?
Yes. WebP stores an alpha channel just like PNG, so transparent backgrounds come through intact.
How much smaller will the file be?
Often dramatically — transparent PNGs frequently drop by 60–80%, because PNG stores every pixel losslessly while WebP compresses far more efficiently.
Is this lossless like PNG?
No. We encode at 92% quality, which trades a small, generally invisible amount of detail for a much smaller file. Keep the original PNG as your editing master.
Should I use WebP for logos and icons?
For the web, yes — it's smaller and every current browser supports it. Keep a PNG or SVG copy for print, email signatures and apps that don't read WebP.
Can I convert several at once?
Yes. Add up to 20 PNGs and they convert in one batch, downloadable individually or as a single ZIP.
Are my images uploaded?
No. Conversion runs entirely in your browser, so your images stay on your device.
