Everything you need to know about image resizing

Which formats can I bulk convert to PNG?

You can batch convert JPG, WebP, and JPEG images to PNG. All formats are fully supported and processed client-side in your browser.

Why convert JPG to PNG in bulk?

PNG is lossless, so no quality data is removed on save. Bulk converting JPGs to PNG is useful when you need to edit images multiple times without accumulating compression artifacts, or when you need transparency support.

Does PNG support transparency?

Yes. PNG supports full alpha-channel transparency. If your source images have transparent areas (e.g., after background removal), converting to PNG preserves that transparency correctly.

Will PNG files be larger than the original JPGs?

Yes, usually. PNG uses lossless compression so file sizes are typically larger than equivalent JPGs. You're trading file size for quality and transparency support. To reduce PNG size without changing format, use our Compress tool.
