My web images are too large and load slowly—what should I do?

Convert PNG/JPG to WebP to shrink file size and speed up loading, ideal for product and article images.

Need to process lots of images for e-commerce or content sites?

Batch convert multiple PNG/JPG files and download them as a ZIP, perfect for new listings or gallery updates.

Will PNG transparency be lost?

No. WebP supports alpha transparency; increase quality or use lossless to preserve the look.

How should I choose the quality slider?

Higher quality looks better but is larger; lower quality is smaller. Lossless preserves fidelity.

File too large for uploads or email?

Convert to WebP to reduce size before form uploads, email attachments, or ticket systems.

Are my images uploaded to a server?

No. Everything runs locally in your browser; files never leave your device.

How do I download if I convert just one image?

Single files download directly as WebP.

How do I download multiple images?
