PNG → JPG Converter
Convert transparent or opaque PNG images to lightweight JPGs in your browser or via our Django API. Control quality and background.
Lower = smaller, Higher = cleaner (typical 0.75–0.90).
Unchecked = transparent areas become black in JPG.
Server mode uses a ZIP for batch downloads.

Local mode keeps files on your device; server mode uploads only to convert and returns downloads—no storage.
PNG vs JPG — When and Why to Convert
PNG keeps sharp edges and transparency; JPG excels at photos with small sizes. Converting can speed up pages significantly when transparency isn’t required.
Good times to convert
- Photo‑like images saved as PNG
- Hero banners without transparency
- Pages where performance is critical
Keep PNG if
- You need transparency (logos/overlays)
- Flat UI or pixel‑perfect assets
- Lossless quality required
Quality tips
- Start at 0.80 quality, adjust after preview
- Choose a background for transparent PNGs
- Check for banding on gradients
Performance & Privacy
Local mode never uploads files. Server mode sends files to the Django endpoint only for conversion; images aren’t stored.
Workflow Tips
- Batch convert in server mode to download a ZIP.
- Keep filenames consistent—this tool preserves base names.
- Preview at 100% zoom to judge compression artifacts.
