Free Online PNG to JPG Converter
PNG files are excellent for graphics and screenshots, but they're often much larger than JPG when it comes to photographs. LovePDFImg's PNG to JPG converter switches your images to the more compact JPG format, which is ideal for sharing photos, uploading to websites, or attaching to emails where file size matters.
The conversion is handled entirely by your browser's Canvas API: each PNG image is drawn onto a canvas and re-exported as a JPG file. There's no upload, no waiting on a server queue, and no limit on how many times you can use the tool. Convert one image or a whole folder's worth, then download everything together as a ZIP archive.
What this converter does to your image
Each PNG is drawn onto a canvas at its original width and height and saved as a JPG at a fixed quality of 92 out of 100. There is no quality slider here and the image is never resized, so a 4000 × 3000 PNG comes out as a 4000 × 3000 JPG. The file keeps its name and only the extension changes to .jpg. If you add one image it downloads as a single JPG, and if you add several they are bundled into one ZIP.
Quality 92 is a deliberate middle ground: files are much smaller than the PNG, and the loss is hard to see at normal viewing sizes. If you need an even smaller file, run the result through Compress JPG, which lets you set a quality or a target size such as 200 KB.
Transparent areas and the background color
JPG cannot store transparency, so any see-through part of your PNG has to become a solid color. The background box accepts a color code such as #FFFFFF for white or #000000 for black. Type it with the leading #. If the value is not a valid color, the browser ignores it and the background can turn out black, so if a transparent logo comes back on a black rectangle, check what is in that box.
Choose the background to match where the JPG will be used. White suits most documents and web pages. For a logo that will sit on a dark slide, use that slide's color, otherwise you will see a white box around it.
When PNG to JPG is the right move
- Photos and gradients. These shrink a lot, because PNG stores every pixel exactly and JPG does not.
- Upload forms with a size limit. Many portals only accept JPG, or cap files at a few hundred KB or a couple of MB. Converting is usually the quickest way under the limit.
- Not for screenshots, text or flat graphics. JPG tends to leave faint halos around sharp edges and letters, and a flat-color image can end up larger than the original PNG. Keep those as PNG, or try PNG to WebP if you only need a smaller file for a website.
The browser may also convert colors to the standard sRGB range when it draws the image, so a PNG with a wide-gamut color profile can look very slightly different after conversion. For everyday photos and graphics this is rarely noticeable.
