Format guide
Why convert JPG to PNG?
PNG is a useful editing and interchange format for screenshots, diagrams, interface assets, and workflows that require lossless saves. Conversion does not recreate detail already removed by JPG compression.
Common uses
When this conversion helps
- Using a photo in software that requires PNG
- Avoiding another lossy save during an editing workflow
- Standardizing mixed JPEG assets as PNG files
Zero-upload privacy
Your files stay yours
Conversion happens with browser technologies on your own device. There is no upload step, no temporary server copy, and nothing to delete later. Closing the tab clears the working session.

Frequently asked questions
Will converting JPG to PNG improve quality?
No. PNG prevents additional lossy compression, but it cannot restore detail already lost in the JPG.
Will the PNG have transparency?
The original JPG has no transparency, so the converted PNG remains fully opaque.
Do JPEG files work too?
Yes. Both .jpg and .jpeg filenames are accepted and validated.
Does anything leave my device?
No. The images are decoded and encoded locally in browser memory.
