How to Convert PNG to JPG Online Free — Instantly

PNG files are lossless and high quality, but they are often 3–10× larger than the equivalent JPG. If you are uploading a photo to a website, attaching it to an email, or submitting it to a form, converting PNG to JPG can dramatically reduce file size — often by 60–80%.

When to Convert PNG to JPG

• Photos with no transparency: A PNG photograph is unnecessarily large — JPG at quality 80 is visually identical but far smaller
• Email attachments: JPG is universally supported; PNG can be large enough to hit attachment limits
• Online forms with file size limits: Many portals require JPG specifically
• Web performance: For photographic content, JPG (or better, WebP) loads faster than PNG
• Do NOT convert PNG to JPG if the image has a transparent background — JPG does not support transparency, and the background will be filled with white.

PNG to JPG: How Much Smaller Will the File Be?

• The size reduction depends on the image content:
• Photograph (natural scene): PNG ~3MB, JPG ~300KB — 90% reduction
• Screenshot: PNG ~500KB, JPG ~200KB — 60% reduction
• Logo / illustration: PNG ~50KB, JPG ~80KB — JPG is actually larger (PNG wins for graphics)
• For photographs, JPG is almost always the right choice. For logos and graphics, keep PNG.

What Happens to Transparent Areas?

• JPG does not support transparency. When converting a PNG with transparency:
• Transparent areas are filled with white by default
• This is correct for most use cases (documents, forms, printing)
• If you need to keep transparency, convert to WebP instead (PNG to WebP) — WebP supports transparency and is even smaller than PNG

Should I Use JPG or WebP?

For web images, convert PNG to WebP instead of JPG — WebP is 25% smaller than JPG and supports transparency. Use JPG when you need maximum compatibility (email, printing, older software).
