How to Convert JPG to PNG

  1. Add your JPG. Drag the file onto the upload area or click to browse. It is read directly in your browser — nothing is uploaded.
  2. Review the conversion summary. The banner shows the original JPG size versus the PNG size, and whether the PNG is larger (it usually will be).
  3. Download. Click Download PNG to save the converted file.

When You Should — and Should Not — Convert JPG to PNG

Good reasons to convert:

  • A design tool or workflow expects PNG, or you want a lossless working copy to edit and re-save without piling on new JPG artefacts.
  • You need crisp edges on text, screenshots, or UI graphics, where PNG holds up better than JPG.

A common misconception: converting a JPG to PNG does not make the background transparent. JPG has no transparency to begin with, so the PNG keeps the same solid background — it is simply lossless now. Removing a background is a separate editing task in an image editor, not something a format conversion can do.

What to Expect for File Size

Because PNG is lossless, a photo grows substantially when converted, while flat graphics may even shrink. Typical results (they vary with image content):

Frequently Asked Questions

Why convert JPG to PNG?

The most common reasons are: (1) you need PNG for a design tool or workflow, (2) you want a lossless working copy you can edit and re-save without adding new JPG artefacts each time, or (3) you are preparing crisp graphics, screenshots, or UI assets where PNG holds edges better than JPG.

Will converting to PNG give my image a transparent background?

No. JPG cannot store transparency, so there is nothing for the converter to bring back — you get a PNG with the same solid background, just in a lossless container. To get a see-through background you have to erase it in an image editor first; that is a separate editing step, not a format conversion.

Does converting JPG to PNG improve quality?

No. The JPG compression artefacts are frozen into the PNG. The result is a lossless copy of an already-compressed JPG — PNG cannot recover detail that JPG discarded. If quality matters, go back to the original uncompressed source.

Why is the PNG usually larger than the JPG?

PNG is lossless — it stores every pixel exactly. JPG reaches its small size by permanently discarding visual information. A PNG copy of a photo is therefore much larger. The exception is flat graphics like logos and icons, where PNG can actually be smaller than a JPG of the same image.

Does converting keep my photo EXIF data?

No. The image is redrawn through the Canvas API, so the PNG comes out without the original EXIF metadata — no camera model, capture date, or GPS location. If you need that data, keep the original JPG.

When do I specifically need a PNG instead of a JPG?

Common cases: importing assets into Figma or Canva, placing crisp graphics in PowerPoint or Word, images for a GitHub README, and emoji or stickers for Discord and Slack. Many of these accept JPG too, but PNG avoids JPG edge artefacts on text and flat colour.

Can I convert multiple JPGs at once?

Not on this page — it handles one file at a time for a clean side-by-side preview. For batch format conversion, the Bulk Image Resizer can process many files and change their format in one go.
