Do you upload or store my images?

No. Everything runs locally in your browser using Canvas. Nothing leaves your device.

Is transparency preserved?

Yes. PNG alpha transparency is preserved when exporting to WEBP.

Can I use lossless WEBP?

Yes. Set quality to 100 to export as WEBP-lossless (or toggle the lossless option if shown).

What quality should I choose?

For UI graphics and icons, 90–100 is safest. For screenshots/graphics where size matters, try 70–90 and review the preview.

Can I batch convert many PNGs?

Yes. Drop multiple files, convert in batches, and download individually or as a ZIP.

PNG to WEBP

Why convert PNG to WEBP?

WEBP supports transparency like PNG but is usually much smaller. Use Lossless for UI assets/icons, or Lossy for photos and illustrations.

FAQ

Does this preserve transparency?

Yes. Both lossy (Canvas) and lossless (ffmpeg.wasm) paths preserve alpha transparency.

When should I use Lossless?

Use Lossless for pixel-perfect graphics like UI, logos, and icons. Use Lossy (quality slider) for photos for much smaller files.
