Accepts .png files
Lower = smaller file size. 85% gives excellent results for most images.
PNG transparency is not supported by JPEG. All transparent areas will be filled with white automatically.
JPG compression can reduce PNG file sizes by 50–80% for photographic images. This makes PNG-to-JPG conversion essential for reducing image storage costs and improving web page loading speed.
Control the JPG quality level (1–100%). Higher quality produces larger files with better fidelity; lower quality gives smaller files with more compression artefacts. Quality 80–85 is optimal for most web use cases.
Since JPEG does not support transparency, any transparent areas in your PNG are filled with a white background before conversion — preventing the black or corrupted fill you get from naive conversions.
Convert PNG to JPG when: you need a smaller file size for web upload or email attachment, the image is a photograph (not a logo or screenshot with text), and transparency is not needed. JPG is the standard for photographic web images because it offers good quality at much smaller file sizes than PNG.
JPEG does not support transparency (alpha channel). This tool fills transparent areas with white — the standard behaviour for print and web backgrounds. If you need a different background colour, use the Image Editor tool to change the background before converting.
For social media profile pictures and avatars, quality 85–90 provides excellent visual quality with file sizes typically under 100 KB. For product images on e-commerce sites, quality 80–85 is a good balance between visual quality and fast loading.
