Websites, presentations, forms, social content and compatibility problems.

Frequently asked questions

1Which format should I choose?

JPEG suits many photos; PNG is useful for sharp graphics and transparency.

2Can quality change?

Yes. Lossy formats can reduce file size by discarding some image information.

3Can transparency be preserved?

Only if the chosen output format supports transparency.

4Should I keep the original?

Yes. Keep it if you may need maximum quality or another format later.

Image Converter Guide

Choose an output format for what you need next, rather than converting simply because another extension is available.

Get a better result

Keep the original file until you have checked the converted result.

Choose a format that supports the features you need, such as transparency or photographic compression.

Check dimensions, transparency and visible quality after conversion before deleting the source.

Quick example

Converting a transparent graphic to a format that does not preserve transparency can change its appearance. Likewise, converting formats does not automatically make an image smaller or higher quality.

Common questions

Does converting improve image quality?

No. Conversion changes representation or encoding; it cannot recreate detail that is missing from the source.

Why did transparency disappear?

Not every image format supports transparency in the same way. Check the capabilities of the chosen output format.

Keep important originals and verify exported files or generated values in the workflow where you intend to use them.
