PNG to WebP converter

Turn a PNG into a web-ready WebP.

Prepare a PNG for modern web delivery without sending the file to a conversion server. The tool preserves the decoded canvas dimensions and lets you inspect the WebP result before saving it.

Format decision

When is WebP a better output than PNG?

PNG is lossless and dependable for sharp graphics, while a lossy WebP can be substantially smaller for photographs or textured artwork. The right result depends on the image, so compare the preview and measured file size rather than assuming conversion always helps.

Transparency-capable outputModern WebP encoding can retain transparent areas from a PNG. Check the preview because browser encoding support still determines the actual result.

Quality you controlThe quality slider changes the lossy WebP encoding. Flat illustrations and text may need a higher setting than a photograph.

Dimensions stay unchangedOnly the format changes on this page. Resize first when the original pixel dimensions are larger than the page placement needs.

Measured before downloadThe result panel reports the generated file size and dimensions, making it easy to keep the PNG when WebP offers no useful saving.

Keep in mind: A tiny palette logo, pixel-art image, or screenshot with crisp text may not benefit from lossy WebP. Keep the original PNG and compare both files in the real page layout before replacing a production asset.

Three local steps

Convert, inspect, then keep.

The page constrains the source format and starts with the intended output, while leaving the quality decision visible.

STEP / 01

Choose one PNG

Open a .png image up to 40 MB. The browser keeps it in the current tab while the converter works.

STEP / 02

Choose WebP quality

Use a higher value for sharp edges and a lower value only when the visual trade-off is acceptable.

STEP / 03

Compare the output

Review the preview and file-size change, then download the .webp only when it is a genuine improvement.

Common questions

PNG to WebP, clearly explained.

Will PNG transparency remain transparent?

WebP supports alpha transparency and the converter does not add a matte for WebP output. The browser must support WebP canvas encoding; the tool rejects a silent fallback to a different format.

Is WebP always smaller than PNG?

No. Photographs and textured artwork often shrink, while simple or already optimized PNG files may show little benefit. The result panel reports the actual size.

Does converting resize the image?

No. This converter keeps the decoded width and height. Use the image resizer when the destination needs different pixel dimensions.

Need a different pair? The general converter supports JPEG, PNG, WebP, and compatible HEIC input from one workspace.
