PNG to JPG Converter

Flatten a PNG into a JPG in the browser, in one step.

Typical use: a photo viewer, an upload form, or a print workflow that wants JPG and will not take a PNG.

Key features

• Renders and re-encodes the image on an HTML5 canvas in the browser.
• Opens your local PNG in the browser without uploading it to a server.
• Exports the JPG as a downloadable file built entirely client-side, with no server round-trip.
• A quality slider (default 0.9) lets you trade the output file size against visual fidelity.

How transparency is handled

Because the JPG format has no transparency channel, any see-through areas in your PNG are painted onto a solid white background before the JPG is written - so a logo or icon that was transparent lands on white rather than turning black. For pictures with a lot of color detail, that makes JPG a smaller, photo-friendly result than the original PNG.

Privacy and data handling

Painting the PNG onto the canvas and encoding the JPG both happen locally through the Canvas API, so the PNG file never leaves your device or gets uploaded. Nothing you choose here is kept past the page session or shared with an analytics or tracking service, and no account or signup is needed.

When to use this vs a sibling converter

Reach for this page when your source is a PNG and the destination has to be a JPG - flattening transparency onto white and re-encoding as a photo-friendly JPG is exactly what it does. If instead you want a smaller file for the web while keeping transparency, convert to WebP with the JPG to WebP converter. Both run in the browser with no upload; picking by your target format keeps each tool doing one job well.
