PNG and JPEG solve different problems. PNG is lossless and supports transparency, which makes it right for logos, screenshots, and line art. JPEG is lossy and usually produces files several times smaller for photographs. Converting a photograph from PNG to JPEG is one of the easiest large file-size wins available — and this converter does it in your browser, with no upload.

How to convert PNG to JPG

  1. Select the PNG file, or several at once for batch conversion.
  2. Choose a JPEG quality level. 80–85 is the usual balance between size and fidelity.
  3. Pick a background colour if the PNG has transparency — JPEG cannot store an alpha channel, so transparent areas must be filled with something.
  4. Convert and download. Your original PNG is untouched.

The PNG to JPG Converter runs entirely in your browser — nothing you enter is uploaded, stored, or logged.

When to use this tool

Shrinking photographs saved as PNG

A screenshot tool or a camera app set to PNG produces files many times larger than necessary for photographic content. Converting typically cuts 70–90% of the size with no visible difference.

Meeting upload format requirements

Many forms and older systems accept JPEG only. Converting is often the whole fix for a rejected upload.

Reducing page weight on a website

Photographic content served as PNG is one of the most common causes of a poor Largest Contentful Paint score. Converting is a one-step improvement.

Things worth knowing

  • Do not convert screenshots containing text — JPEG compression produces visible ringing around sharp edges. Keep those as PNG.
  • Transparency is lost permanently. Decide on the background colour deliberately; white is the usual default but is wrong on a dark page.
  • JPEG is lossy, so each save discards more information. Convert from the original PNG rather than re-saving a JPEG repeatedly.
  • If you need both small files and transparency, WebP does both and is supported by every current browser.

Frequently Asked Questions

What happens to transparent backgrounds when converting PNG to JPG?

Because JPG does not support transparency, our tool fills transparent areas with clean white (or your chosen background color).

What happens to transparency when converting PNG to JPG?

It is lost, because JPEG has no alpha channel. Every transparent pixel is replaced with the background colour you choose. If the original had a soft transparent shadow, that shadow will now blend into that flat colour, which looks wrong on any other background. When transparency matters, convert to WebP instead.

Will converting reduce image quality?

Slightly, since JPEG is lossy. At quality 80–85 the loss is imperceptible in photographs. It is very visible in screenshots, diagrams, and anything with sharp text edges, where JPEG introduces halos that PNG does not.

How much smaller will the JPEG be?

For photographic content, typically 70–90% smaller. For flat-colour graphics, logos, or screenshots, JPEG may actually produce a larger file than PNG while also looking worse — PNG compresses large areas of uniform colour extremely efficiently.

Is JPG the same as JPEG?

Yes, identical. The three-letter extension is a holdover from MS-DOS filename limits. Both refer to the same format, and no system distinguishes between them today.

Are my files uploaded during conversion?

No. Conversion happens on a canvas element in your browser. The image is never transmitted, so this is safe for private photographs and documents.
