Questions frequentes

Does converting JPG to PNG improve image quality?

No. PNG conversion changes the file format but cannot restore detail that was already removed by JPG compression.

Will the PNG have a transparent background?

Not automatically. A JPG has no transparency data, so the converted PNG keeps the visible background from the source image.

Why can the PNG be larger than the JPG?

PNG and JPG use different compression methods. Photographs often produce larger PNG files even though the visible image looks similar.

Can I convert several JPG files together?

Yes. The workflow accepts a batch of supported JPG files and packages the converted PNG files into one ZIP download.

Will the filename change?

The filename stem is preserved where possible and the extension changes from JPG or JPEG to PNG.

When is PNG a better choice?

PNG is useful when a specific workflow requires PNG or when screenshots, diagrams, and text-heavy graphics will be edited further.

Quand utiliser cet outil

Convert JPG images to PNG when a workflow specifically requires PNG files or when you want a lossless container for later editing. Conversion does not restore detail already removed by JPG compression.

An editor, form, or asset pipeline requires PNG input.
A JPG screenshot or diagram will be edited repeatedly after conversion.
You need a PNG copy while retaining the original JPG separately.

Conseils pour de meilleurs résultats

Do not expect conversion to create transparency that is not present in the JPG.
Expect some PNG outputs to be larger because PNG and JPG use different compression methods.
Inspect edges and text from the source image before conversion because existing JPG artifacts remain.

Confidentialité et rétention des fichiers

JPG files are temporarily converted and packaged for download; the service does not use the conversion as permanent image hosting. Inputs and PNG outputs are scheduled for cleanup within about 30 minutes.
