Convert PNG images to JPG — or flip it the other way — right in your browser. Handles transparency, no uploads ever.
Your files never leave this deviceFour steps, a few seconds, zero uploads.
Drag images onto the box above, or click Browse. Drop PNGs to go to JPG, or drop JPGs to go to PNG — the tool detects the direction automatically.
When converting to JPG, choose a quality level (default 92%) and pick a background colour to fill any transparent areas.
Latch re-encodes your images using the browser's built-in Canvas API — instantly and offline. Nothing leaves your device.
Save files one at a time, or grab everything at once in a single zip. That's it.
No. Conversion happens entirely in your browser using the Canvas API. Nothing is sent to a server — the tool works offline too.
JPG doesn't support transparency. You can choose a background colour to fill those areas — white is the default, but you can pick any solid colour using the colour picker.
Yes. Just drop JPG files and the tool automatically switches to JPG → PNG mode. PNG output is lossless, so no quality is lost in the conversion.
92% is a great default — visually identical to the original with a noticeably smaller file. Use 95–100% for images that will be printed; 70–80% for web thumbnails where file size matters more than sharpness.
You can convert up to 50 images at once, up to 50 MB each. The real constraint is your device's available memory — most image batches are well within those limits.
