Why use this converter

  • No further degradation

    Repeated edits and saves stop compounding losses.

  • Accepted where JPG is not

    Some tools and pipelines specify PNG.

  • Better for graphics and text

    Sharp edges stay clean rather than picking up artefacts.

  • A base for transparency

    You cannot add transparency to a JPG; you can to the PNG.

When PNG is the right target

When the format itself is the requirement:

  • An image you will edit repeatedly: PNG avoids compounding loss across saves.
  • Tools that require PNG: Some pipelines and upload forms specify it exactly.
  • Screenshots and flat graphics: PNG keeps sharp edges clean.
  • Preparing to add transparency: Converting first makes it possible.

Why the PNG comes out larger

PNG compresses losslessly by finding repetition, which is abundant in flat colour and nearly absent in photographs. JPEG instead discards detail the eye is unlikely to notice.

So a photograph stored as PNG is routinely several times larger than the same photograph as JPEG, for no visible benefit — the detail JPEG removed has already gone. For screenshots and graphics the calculation reverses, and PNG can be both smaller and visibly better.

Converting does not create transparency

PNG supports transparency; JPG does not. Converting gives you a file capable of holding it, but every pixel in the source is opaque, so every pixel in the result will be too.

Removing a background needs an editor. Converting is the step that makes it possible, not the step that does it.

Frequently asked questions

Will converting improve my image?

No. PNG prevents further loss, but detail JPEG already discarded cannot be recovered.

Why is the PNG so much larger?

PNG is lossless and handles photographic detail far less efficiently than JPEG. Several times larger is normal for photos.

Do I get a transparent background?

No. The result can hold transparency, but nothing in the source is transparent. That needs an image editor.

When should I prefer PNG?

For screenshots, graphics, text and anything you will keep editing. For photographs being published, JPG is usually better.
