Free online PNG ↔ WEBP bidirectional converter. Process images locally in your browser to reduce file size and protect your privacy.

Overview
Understand what the tool solves, how it works, and the boundaries of its data.
This page accepts PNG and WebP images and converts each file to the opposite format. Add one or more files, preview the source and converted result, then download the output. A PNG input becomes WebP; a WebP input becomes PNG. The conversion starts automatically after files are added.
WebP is an image format with lossy and lossless encoding modes and transparency support. This converter requests WebP encoding at a fixed quality setting; it does not offer a quality slider or guarantee a smaller file. A small or mostly flat PNG may not shrink, and lossy encoding can change image detail.
Guide
Follow the workflow and verify inputs and outputs with practical examples.
Drop files into the upload area or select them from your device. You can add multiple images and each is converted in the direction implied by its input format.
Wait for the conversion status to complete, then compare the preview with the source. An error may indicate an unreadable input or an unsupported browser encoding path.
Use the result’s download control. Keep the source if exact pixels, color behavior, or transparency handling matters to your workflow.
For a PNG logo, the output is WebP; for a WebP image that needs a broadly readable raster copy, the output is PNG. Check the downloaded file in the destination application before replacing the original.
Use cases
See how the tool fits into real work and everyday tasks.
Convert a PNG illustration to WebP for a web publishing workflow, then compare the actual output size and appearance before deployment.
Create a PNG copy when a document or editing workflow expects PNG. Keep in mind that re-encoding does not restore information lost in an earlier lossy conversion.
Add multiple PNG or WebP files in one session, review each result row, and download the converted items you need.
Q&A
Find concise answers to common questions and confusing cases.
No. The result depends on the image content and encoding. Compare the downloaded file size; this tool does not promise a reduction.
WebP supports transparency, but inspect the actual output in your target software, especially when the image is important to a production design.
Image decoding and format encoding depend on browser capabilities and image dimensions. Try a standard PNG or WebP input and verify the downloaded extension and preview.
Notes
Review scope, result limitations, and important precautions before use.
Conversion re-encodes pixels and may alter fine details or file size. The WebP output uses a fixed quality parameter, so there is no control here for choosing a different quality or a lossless mode. Preview the result at its intended display size and retain the source until it has been checked.
Large images can require substantial browser memory during decoding and conversion. This tool does not promise support for every image size or every browser’s WebP encoder.
