Converting PNG to JPG makes an image much smaller, which is ideal for email, web pages, and anywhere file size matters. PNG is lossless and supports transparency, so it produces large files; JPG uses efficient compression that shrinks photos dramatically with very little visible difference. For a photograph or a full-color image, the JPG can be a fraction of the PNG's size.

File Transmute converts your PNG to JPG entirely in your browser — the image is never uploaded, there's no sign-up, and there's no daily limit. It's instant and works offline once the page is loaded.

One thing to keep in mind: JPG doesn't support transparency. If your PNG has a transparent background, those areas are filled with a solid color (usually white) when converting, because JPG can't store "see-through" pixels. For photos and screenshots without transparency, that's no issue and JPG is the better, smaller choice. For logos or graphics that need a transparent background, keep them as PNG.

JPG is the most universally supported image format — it opens on every device, app, and website with no compatibility concerns — which makes it the safest choice for sharing and uploading. If you want even smaller files for the web, consider converting to WebP.

Best for

  • Making a large PNG screenshot small enough to email or upload
  • Converting graphics for a site or form that expects JPG
  • Reducing storage for photo-style images that don't need transparency

Good to know

JPG doesn't support transparency, so transparent areas are filled with a background colour. For photographs the size savings are large; keep PNG for logos, icons, or anything needing sharp edges or transparency.

Frequently asked questions

It is lost. JPG has no transparency channel, so any transparent area is filled with a solid background colour. If you need the transparency, stay with PNG or use WebP — this is the single most common reason not to convert.

For photographs, dramatically — often by many times over, because JPG is lossy and PNG is lossless. For flat graphics, logos, and screenshots of text, the saving is much smaller and the quality cost is more visible.

No. Logos need sharp edges and usually transparency, and JPG smudges hard edges while flattening transparency. Keep logos as PNG or SVG.

When the image has a transparent background, when it is a logo or icon, or when it is a screenshot containing text — all cases where PNG's lossless, sharp-edged output is the right choice.
