PNG to JPG
Convert PNG images to JPG, usually a much smaller file. GIF and BMP work too. Pick the quality and the color that fills transparent areas. Your browser converts each image on your device. Nothing is uploaded.
Bytes of your files sent anywhere: 0
Files are read and converted in this tab, in a background worker. The only requests the page makes are for its own scripts. Your files are never sent anywhere.
How it works
PNG stores every pixel exactly, which is right for screenshots and diagrams but makes photos large. JPG stores photos in a fraction of the space by dropping detail the eye barely sees, which is why upload forms with a size limit often ask for it.
Your browser already reads PNG, GIF and BMP. This page asks it to decode each file in a background worker, draws it on an off-screen canvas over the fill color you pick, and writes a JPG at the quality you set.
JPG has no transparency, so transparent areas become the fill color, white unless you change it. Text and sharp lines can show faint ripples in a JPG; keep those images as PNG, or use quality 95 or more.
On a Mac, Née, our file converter, makes JPEG copies from Finder: hold Option while dragging the images and drop them on the action you want.
How to convert PNG to JPG
- Set the quality and fill. 92 suits most images; lower it for a smaller file. Pick the color for transparent areas.
- Add the images. Drop the PNG, GIF or BMP files on the box, click it to choose them, or paste an image you copied.
- Wait for each row. Each image is converted in turn and the row shows the old and new size.
- Download. Download each JPG from its row, or use Download all as .zip.
Limits
- Up to 100 MB a file and 200 files at a time.
- An animated PNG or GIF gives one JPG of its first frame, and the row says so.
- Text notes stored in a PNG and any EXIF data are not copied into the JPG.
- On an iPhone or iPad, the browser can draw at most about 16.7 megapixels.
- Needs Chrome or Edge 69, Firefox 105 or Safari 16.4, or later.
