Why convert PNG to JPG?
PNG is a lossless format — it stores every pixel exactly, which is perfect for logos, screenshots, and graphics with sharp edges or transparency. But that precision comes at a cost: a photograph saved as PNG can be three to five times larger than the same image as a JPG. When you don't need transparency or pixel-perfect edges, converting to JPG is the fastest way to cut file size.
Typical reasons people make this switch:
- Uploading photos to sites that have size limits or are slow with large PNGs.
- Emailing or messaging images that are currently too big to send.
- Speeding up a web page where a PNG photo is bloating the page weight.
- Saving storage on a phone or drive full of screenshots and saved images.
The one thing to watch: transparency
JPG cannot store transparency. If your PNG has a transparent background — common for logos and cut-out product shots — those transparent pixels are filled with white when you export to JPG. For a photo with no transparency that's irrelevant. For a logo you want to place on a coloured background, convert to WebP instead, which keeps the alpha channel.
Start at 85% quality. For most photos that's visually identical to the original at a fraction of the size. Drop toward 70% only if you need an even smaller file and can accept slight softening.
How to convert
- The format above is already set to JPG. Set a quality level (85% is a good default).
- Drag your PNG files onto the drop zone, or click to browse. Add up to 200 at once.
- Each file shows its before/after size. Download them one by one, or grab all of them as a ZIP.
WebP supports transparency and beats both PNG and JPG on size.
