How to use
Convert JPG images to PNG. Choose your file or enter the requested content, select options, then run the tool and download the result.
When should you convert JPG to PNG?
PNG is useful when you need lossless storage of the pixels in the current image or a format commonly used for graphics. However, converting a JPG to PNG does not restore detail already lost during JPEG compression, and it may create a larger file. A JPG also cannot gain a transparent background simply by being saved as PNG.
Check the output
- Compare the PNG with the original at normal viewing size.
- Check dimensions and file size before using it on a website.
- If you need transparency, edit or remove the background with an appropriate image editor.
- Keep the original JPG in case you need a smaller photographic version.
Choose PNG for a specific compatibility or editing need, not because the extension alone guarantees higher visual quality.

No. File processing runs in your browser; the selected file is not sent to a Tolvix processing server.
Will all features be preserved?
Not always. Browser-based conversion may not preserve every annotation, form, font or advanced document feature.
