Convert PNG to WebP
Re-encode PNG graphics as WebP to cut file size dramatically for the web while keeping transparency intact.
Free workspace
Keep repeat file work in motion after the first export.
Start here without an account, then move into retained files, OCR, and starter workflows when the task stops being a one-off.

Conversion surface
Run the file task now.
The converter stays fast and simple. Workspace features only step in when retention, OCR, or repeat work actually adds value.
How it works
A short path from input to finished export.
The flow stays simple so you can get in, finish the job, and move on without extra setup.
Upload PNG Files
Drag and drop your PNG images or click to browse. You can queue several files at once.
Adjust Quality
Use the quality slider to balance file size against fidelity. The default of 85% suits most images.
Download WebP
Save the converted file right away. Multiple images are bundled into a ZIP for one-click download.
Why FileMorf
A cleaner route for this conversion.
The tool keeps the core job lightweight while still giving you room to grow into retained, higher-value workflows later.
100% Private
All processing happens in your browser. Your files never leave your device.
Smaller Files
WebP's modern compression delivers the same visual quality as older formats in a fraction of the bytes.
Batch Processing
Convert multiple files at once. Download as a convenient ZIP file.

The important questions, plus the nearby routes users usually need next.
WebP compresses far more efficiently than PNG — screenshots and UI graphics often shrink by 60-80% — while still supporting full alpha transparency. That makes it the standard swap for speeding up page loads without redesigning any graphics. Keep the PNG as your editing master and serve the WebP.
Yes. Both PNG and WebP store a full alpha channel, and FileMorf preserves it exactly — anti-aliased edges, soft shadows, and semi-transparent pixels all survive the conversion.
WebP uses lossy compression, so some pixel data is discarded — that is exactly where the size savings come from. At the default quality setting the loss is invisible for most images. Keep the PNG original as your master copy and re-export whenever you need a different balance of size and quality.
Every modern browser — Chrome, Firefox, Edge, and Safari 14 or later — displays WebP natively, and current versions of major image editors open it too. Only quite old software may struggle, which is one reason to keep your original file as a fallback.
Screenshots, UI graphics, and logos typically shrink by 60-80%, because WebP compresses both flat color and fine detail far more efficiently than PNG's aging DEFLATE algorithm.
