Does converting PNG to WebP upload my files?
No. The PNG to WebP conversion runs locally in your browser, so your images stay on your device.

Convert PNG to WebP
Convert PNG images to the WebP format locally in your browser, one file or a whole batch at a time.
- Files stay on your device.
- Processed locally in your browser.
- No uploads. No storage.
Convert Image changes JPG, PNG, WebP, SVG, and GIF inputs into JPG, PNG, or WebP output inside the browser.
A selected output format is applied across the batch, and multiple results download together as a ZIP file.
What you can do
- Convert individual images or mixed batches.
- Choose JPG, PNG, or WebP output where the browser supports it.
- Use format-specific routes that restrict the accepted input type.
Before you start
- JPG cannot preserve transparency, so transparent areas are filled with white.
- Animated GIF inputs convert only their first frame to a static output image.
- SVG input is rasterized at its intrinsic dimensions; raster images are not traced into SVG output.
How it works
- Choose the PNG images you want to convert.
- VaultIMG converts them to WebP locally in your browser.
- Download the WebP output, as a ZIP for multiple files.
Common questions
Can I convert several images at once?
Yes. You can add multiple files, and the selected output format is applied to the whole batch.
