About this tool
About this tool
PNG to JPG Converter re-encodes PNG images as JPEG using the browser canvas. Transparent pixels are flattened onto a solid white background because JPEG has no alpha channel, and a quality slider controls the trade-off between file size and sharpness. Everything runs locally on your device.
Turn PNG files into JPG images without uploading them anywhere. Screenshots, exported graphics, and transparent PNGs are re-encoded as JPEG with a clean white background where transparency existed, which usually also produces a smaller file for photographic content.
Built for daily work
- Convert PNG screenshots to JPG for email attachments and shared documents.
- Prepare transparent PNG graphics for systems that only accept JPEG uploads.
- Shrink photographic PNG files before uploading them to a content management system.
- Create JPG versions of design exports for clients who use older office software.

JPEG cannot store transparency, so transparent areas are filled with white, the expected behavior for photos and documents.
Smaller files for photos
Photographic PNGs often shrink dramatically when re-encoded as JPEG at a sensible quality.
Purpose-built defaults
The target format is pre-selected to JPG, so the tool behaves like a dedicated PNG to JPG conversion.
Fully local encoding
The canvas API performs the conversion in your browser; the source file is never transmitted.

Frequently asked questions
Frequently asked questions
They are filled with white. JPEG has no transparency channel, so any transparent pixel becomes white in the output.
JPEG is a lossy format, so fine detail is approximated. At high quality settings the difference is usually invisible on screen.
No. The conversion uses the browser canvas API locally, and the source file never leaves your device.
This focused tool handles one image at a time. For bulk work, repeat the conversion for each file.
