What Is PNG to JPG Conversion?

PNG and JPG (JPEG) are the two dominant raster image formats. PNG uses lossless compression and supports transparency, which makes it a popular choice for screenshots, logos, and design exports. JPG uses lossy compression — it discards detail to achieve dramatically smaller files, ideal for photographs and anywhere file size matters. Converting PNG to JPG re-encodes the image with lossy compression and removes transparency, which usually shrinks the file by 60–90%.

When to Convert PNG to JPG

  • Faster page loads: Photographs saved as PNG bloat page weight. JPG at 85% quality looks identical and loads many times faster.
  • Email attachments: A 12 MB PNG photo often becomes a 1–2 MB JPG that fits under a 25 MB Gmail limit even with several attached.
  • Marketplace listings: Etsy, eBay, and Amazon limit file size per image. JPG fits comfortably inside their limits.
  • Sharing on chat apps: WhatsApp and Telegram re-compress PNGs to JPG anyway — converting locally lets you control the quality instead of letting their server decide.

What You Lose

Transparency disappears. Any transparent pixels in the PNG are filled with the background colour you pick (usually white). Logos with transparent backgrounds will gain a coloured rectangle. If transparency matters, keep the file as PNG or convert to WebP, which supports both lossy compression and transparency.

Quality vs File Size

JPG quality is a slider from 1–100. 100 is the largest, near-lossless. 85–95 is the sweet spot — visually identical to the source for most images. 75–85 is fine for thumbnails and previews. Below 70 the lossy artifacts become visible, especially around text, fine lines, and gradients.

Privacy

This converter runs entirely in your browser. Your PNG is read by the browser's Canvas API, redrawn, and re-encoded as JPG without ever being sent to a server. There is no upload, no tracking, and no retention.

Frequently asked questions

Why convert PNG to JPG?

JPG files are usually 60–90% smaller than the equivalent PNG, which makes pages load faster and emails fit inside attachment limits. The trade-off is that JPG is lossy and does not support transparency.

What happens to transparent areas?

JPG cannot store transparency, so transparent pixels are filled with the background colour you pick (white by default). For PNG logos with transparency you want to keep, stay with PNG or convert to WebP.

What quality should I use?

85–95% is visually identical to the source for most photos and screenshots. Below 70% you may see compression artifacts around text and sharp edges.

Is the file uploaded?

No. Conversion runs in your browser using the Canvas API. The image is decoded and re-encoded on your device.
