PNG files are often enormous for what they contain. A screenshot or an exported photo can easily be four or five times the size of the equivalent JPG, and most of the time nothing about the image needs the extra bytes. Converting to JPG is how you make it sendable.
This tool re-encodes your PNG as a JPG with a quality slider you control, entirely inside this tab. The image is never uploaded, so there is no waiting on a queue and no copy of your photo on a server somewhere.
How to convert PNG to JPEG
- Add your PNG. Drag it onto the box above or click to browse. The file is read directly by this page.
- Choose a quality. 82 is a good default. Lower it for a smaller file, raise it if the image has text or sharp edges you need to keep clean.
- Download the JPG. The converted file downloads straight away with the same name and a .jpg extension.
When you should not convert a PNG to JPG
If the image has a transparent background, converting it destroys that permanently and you will get a white box behind your logo. If the image is a screenshot, a diagram, a chart or anything with text, JPG's compression will visibly degrade the edges while saving you less than you expect, because PNG already compresses flat colour extremely well.
The rule of thumb: photographs to JPG, everything else stays PNG. If the PNG is huge and it is not a photograph, the Image Compressor or a WebP conversion will serve you better.
Frequently asked questions
- Will I lose quality converting PNG to JPG?
- Yes, and that is the point. PNG is lossless and JPG is not, so the conversion always discards some information in exchange for a much smaller file. On a photograph at quality 82 the loss is essentially invisible. On a screenshot full of text it is not, and you will see faint grey fringing around the letters.
- What happens to my transparent background?
- It becomes white. JPG has no alpha channel at all, so transparency cannot survive the conversion. Every transparent pixel is composited onto a white background before encoding, which is why a logo with a transparent backdrop comes out sitting on a white square. If you need the transparency, stay on PNG or use WebP.
- How much smaller will the file be?
- For a photograph, typically 60 to 90 percent smaller at quality 82. For a screenshot or a flat graphic with large areas of solid colour, sometimes barely smaller at all, because PNG is already very good at exactly that kind of image. If a conversion barely saves anything, that is a sign the file should have stayed a PNG.
- Is my image uploaded to a server?
- No. The conversion uses your browser's own canvas engine. The image is decoded, redrawn and re-encoded on your machine, and the result is handed straight back to you as a download. Nothing is transmitted at any point.
- Can I convert several images at once?
- This tool handles one image at a time so the quality slider applies to exactly what you are looking at. For bulk work, run them through one after another; nothing is uploaded, so there is no rate limit or queue to wait on.
