Use WebP for efficient modern websites, JPG for photographic compatibility, and PNG for crisp lossless graphics or transparency. Conversion preserves the original pixel dimensions.

Frequently Asked Questions

Are my images uploaded?+

No. Reading, conversion, previews, ZIP creation, and downloads happen in your browser.

Which formats support transparency?+

PNG and WebP support transparency. JPG does not, so transparent pixels use your selected background color.

Does conversion compress automatically?+

No. Optional compression is off by default. Enable it only when you want a smaller JPG or WebP file.

Does conversion resize images?+

No. The original width and height are preserved.

Can JPG be pixel-identical?+

JPG uses lossy encoding by design. With compression off this tool requests maximum browser quality, while PNG output is lossless.
