When to use this
You have a PNG screenshot or graphic and you need it smaller — fast. A 2 MB PNG photograph compresses to 200–400 KB as a JPG at 85% quality with no visible difference. If the image doesn't need transparency, this conversion is almost always worth it.
Common triggers: email attachment limits, CMS upload caps, social media platforms that re-compress PNGs badly (looking at you, Twitter/X), or you're batch-processing hundreds of product photos and every kilobyte matters at scale.
When it doesn't make sense: logos with sharp edges and flat colors, pixel art, screenshots of text, or anything where you need the transparent background. For those, keep the PNG or convert to WebP instead.
Good to know
Transparency becomes white. JPG has no alpha channel. Every transparent pixel gets filled with a solid white background. If your PNG has transparency and you need to keep it, use WebP instead — it supports alpha and still beats PNG on file size.
The size drop is dramatic. A typical 3 MB PNG photo becomes 300–500 KB as a JPG. That's a 5–10x reduction. Screenshots with lots of solid color see smaller but still meaningful savings, usually 2–4x.
Quality below 80% gets noticeable. JPG compression creates blocky artifacts around sharp edges and in areas of solid color. For photos, 85% is the sweet spot. For graphics with text or UI elements, stay at 90%+ or the edges get muddy.
JPG degrades on re-save. Every time you open a JPG and save it again, it re-compresses and loses more data. If you plan to edit the output, do your editing first and export to JPG as the final step.
No server, no upload. Conversion happens in your browser via the Canvas API. Your files never leave your device.
