PNG, JPG, WebP: the right format for each use
| Format | Compression | Transparency | Best for |
|---|---|---|---|
| PNG | Lossless | Yes | Logos, screenshots, graphics, text |
| JPG | Lossy | No | Photos, gradient-rich images |
| WebP | Lossy or lossless | Yes | Modern web: lighter photos and graphics |
Rule of thumb: WebP whenever the target is a website, JPG for maximum compatibility (email, legacy software), PNG when every pixel matters or transparency is required.
Converting from a lossy format (JPG, WebP) to PNG does not restore original quality: it simply freezes the current image without further loss.
Frequently asked questions
Which format should I pick: PNG, JPG or WebP?
PNG for graphics, logos and screenshots with transparency; JPG for photos where a small file matters more than perfection; WebP for the modern web, as it is typically 25–35% lighter than JPG at equivalent quality.
Is my image uploaded to a server?
No. The conversion is done by your browser’s Canvas API. The image never leaves your device, which is as fast as it is private.
Why does my PNG converted to JPG get a white background?
JPG does not support transparency, so transparent areas are filled with white during conversion. To keep transparency, choose PNG or WebP.
What does the quality slider control?
For JPG and WebP (lossy formats), it controls the trade-off between file size and visual fidelity. 80–92% is a good range; below 70%, artifacts become visible. PNG is lossless, so the slider does not apply.
Why is WebP unavailable?
A few browsers (notably older Safari or Firefox versions) cannot encode WebP. In that case the option is disabled — reading WebP remains universal though.
