How it works

JPG to PNG Converter for private browser workflows

Why convert JPG to PNG?

PNG supports transparency and lossless compression, making it ideal for logos, icons, screenshots and graphics that need sharp edges or transparent backgrounds.

Local browser conversion

Your JPEG file is decoded and re-encoded as PNG entirely in your browser. No server upload is needed, keeping private photos on your device.

Quality preservation

PNG is lossless, so converting from JPG to PNG preserves the current pixel data without adding further compression artifacts.

Common use cases

Convert JPG logos to PNG for transparent backgrounds on websites and presentations.

Logos and icons

Turn JPEG screenshots into PNG for sharper text and UI elements.

Screenshots
