About Image Converter
Convert images between PNG, JPG and WebP, with control over quality for the lossy formats.
Choosing the target format is the decision that matters. JPEG suits photographs, where lossy compression is nearly invisible and the savings are substantial, but it cannot store transparency and produces visible artefacts around sharp edges and text. PNG is lossless and supports transparency, making it right for logos, screenshots and anything with text or flat colour โ at a considerably larger file size for photographs. WebP handles both cases and is typically 25-35% smaller than an equivalent JPEG at matching quality, with support in every current browser.
The rule that saves the most trouble: converting away from a lossy format never restores what was lost. A JPEG converted to PNG becomes lossless from that point on, but the compression artefacts already baked in remain โ you get a larger file containing the same degraded image. Always convert from the highest-quality original you have.
Converting a PNG with transparency to JPEG discards the alpha channel entirely, and transparent areas usually become black or white. If transparency matters, the target must be PNG or WebP.

Frequently asked questions
Which format should I convert to?
JPEG for photographs. PNG when you need transparency or sharp edges such as logos, screenshots and text. WebP for web use, where it is usually 25-35% smaller than JPEG at matching quality.
Does converting a JPEG to PNG improve quality?
No. It stops further loss from that point but cannot recover artefacts already baked in โ you get a larger file containing the same degraded image. Always convert from the best original available.
What happens to transparency when converting to JPEG?
It is discarded, since JPEG has no alpha channel. Transparent areas typically become black or white. Convert to PNG or WebP if transparency must be preserved.
Are my images uploaded?
No. Conversion runs in your browser via the Canvas API, so files never leave your device.
