Why convert JPEG to PNG?

PNG is lossless and supports transparency. Use it when you need to edit the image again without quality loss.

Will the file get larger?

Usually yes. PNG is lossless so it stores more data. Use WebP if file size matters.

Is my JPEG uploaded to convert it?

All processing runs in your browser with the Canvas API. Our servers are not involved at any point.

Does converting to PNG improve a JPEG's quality?

The PNG keeps the JPEG's pixels exactly as the browser decoded them, so artifacts already in the photo stay. What PNG adds is that later edits and saves lose nothing more.

QUALITY –

PNG is lossless and ignores quality.

Runs entirely in your browser

How it works

The JPEG is decoded onto a canvas and saved with canvas.toBlob('image/png'), a lossless encode, so the quality slider is switched off. The PNG stores exactly the pixels the browser decoded, including any artifacts already in the JPEG, which is why it is usually several times larger.

Processing runs in your browser

All conversion happens using the Canvas API inside your browser. Our servers are not involved at any point.

To shrink the file size after converting, try compress image. For resizing converted images to fit a target, use resize image. To trim the converted image to an aspect ratio, see image crop.
