Ofte stilte spørsmål

Can I convert JPG to PNG online for free?

Yes. Upload a JPG or JPEG image, choose PNG as the output format, and download the converted PNG file for free with no registration.

Will converting JPG to PNG make the image transparent?

No. Converting a JPG to PNG preserves the visible image, but it cannot recreate transparency that was not in the original JPG file.

Does JPG to PNG conversion improve image quality?

PNG uses lossless compression, so the new PNG will not add extra JPG compression damage. It cannot restore detail already lost in the original JPG.

When should I use PNG instead of JPG?

Use PNG for screenshots, graphics with text, icons, UI images, drawings, and files that need crisp edges or repeated editing without new compression loss.

Can I convert multiple JPG files to PNG at once?

Yes. Add multiple JPG images, choose PNG as the target format, and convert them together. Each uploaded file can be up to 1 GB.

Are my JPG images private?

Files are processed securely and automatically deleted after conversion. Your images are not kept for long-term storage.

Hva skjer når JPG blir til PNG

Kildeformat

JPG uses lossy compression and does not support transparency.

Målformat

PNG uses lossless compression and supports full transparency.

Hva endres

The JPG pixels are decoded and written using PNG compression and color capabilities.

Hva bevares
Pixel dimensions and visible composition are preserved unless resize or crop settings are selected.
Hva kan gå tapt
Layers, editable vectors, camera-raw controls, animation, high bit depth, and metadata are preserved only when PNG supports them.
Konsekvenser for kodek og kvalitet
Writing PNG without further lossy compression avoids additional codec loss, but it does not restore detail discarded by the JPG encoding.
Praktiske begrensninger
Multi-page, layered, animated, camera-raw, or very large images may be flattened, reduced to one frame, or rejected if the decoder cannot safely read them.

Konverteringstrinn

  1. Last opp en JPG-fil på maksimalt 1 GB.
  2. Kontroller at PNG er valgt som målformat.
  3. Start konverteringen. En frisk og kompatibel arbeider begynner behandlingen umiddelbart.
  4. Last ned PNG-filen og kontroller resultatet før du sletter kildefilen.

Feilsøking

JPG-filen avvises eller kan ikke åpnes.
Kontroller at filen ikke er tom, passordbeskyttet eller skadet, og at det faktiske formatet samsvarer med filtypen.
PNG-filen er større enn forventet.
Velg en mer effektiv kodek eller lavere kvalitetsinnstilling når det er tilgjengelig. Formater uten kvalitetstap og ukomprimerte formater er ofte større av natur.
Transparency, color, or animation changed.
Choose a target that supports the needed feature and keep the original file; JPG cannot store transparency or animation.
