PNG to WebP Converter
Turn PNG files into smaller WebP images while keeping every transparent pixel. Drop in your logos and UI assets, pick a quality level, and download the batch.
What Is This Tool?
PNG earned its place as the designer's favorite: lossless pixels, crisp text, and true transparency. But that fidelity has a price tag — PNG files are often three to four times heavier than a well-encoded WebP of the same image.
This converter re-encodes PNG to WebP with the alpha channel fully preserved. Logos, icons, screenshots, and UI elements keep their clean edges and transparent backgrounds, just in a file that loads faster.
Because the heavy lifting happens in your browser through WebAssembly, batch jobs stay fast and completely private. Add a whole design folder, tune the quality once, and export the results together.
How to Use
- Load your assets — drag PNG files into the drop zone, click to open your file picker, or paste from the clipboard. The queue shows every image with its current size.
- Balance quality against size with the slider (1-100). For flat graphics and UI, even 80-90 keeps edges crisp while trimming the file significantly.
- Run the batch with "Start conversion". Each row updates with its own progress bar, so you can watch the queue work through your files.
- Collect the output — per-file Download links appear as each image completes, or export the full set with Download All / Download ZIP.
- Need the original PNGs back for an editor? "Re-select" clears the queue, and our WebP to PNG converter restores lossless output anytime.
FAQ
Does WebP actually support transparency?
Fully. WebP carries an alpha channel just like PNG, so transparent logos and cutouts convert cleanly without a background being baked in.
Will I notice quality loss on logos and text?
At quality 80+, flat colors and text stay pixel-crisp — WebP is especially efficient on graphics. Lower quality only matters for photos with soft gradients.
Is my design work uploaded anywhere?
No. Conversion happens locally with WebAssembly, so proprietary assets and client work never leave your machine.
How many PNG files can I convert at once?
As many as you want — there is no hard limit. The queue processes them one by one, and memory is the only practical constraint.
Why is my PNG smaller as WebP?
WebP combines better prediction, sharper color handling, and modern entropy coding. The same visual data simply packs into fewer bytes.
Can I convert WebP back to PNG?
Yes — our WebP to PNG converter restores a lossless PNG, which is handy for editors and workflows that require the original format.
