When to use JPG to PNG

You're building a slide deck and the company logo you grabbed from a press kit is a JPG — white box and all. Drop it here and your browser's Canvas API re-encodes it as a lossless PNG so you can knock out that background in Figma or Keynote without JPEG artifacts creeping into the edges. The conversion runs locally; nothing is sent to a server, so airport Wi-Fi is fine. You walk away with a PNG that holds every pixel exactly as it was — ready to layer, mask, or hand off to a designer who needs a clean source file. Also useful when you're archiving product photos and want a format that won't degrade through repeated saves.

  • Remove a white background from a product JPG in Figma
  • Archive a scanned document without adding compression artifacts
  • Prepare a logo for a Keynote slide with a dark background

Frequently asked

Is this JPG to PNG converter private? Do you upload my images?
No uploads. The conversion runs on your computer — your images are not uploaded anywhere and the tool works offline.
Why convert JPG to PNG?
PNG is lossless and supports transparency. Convert to PNG when you need pixel-perfect quality, transparent backgrounds, or plan to edit the image further without quality degradation.
Will the file size increase?
Usually yes — PNG files are larger than JPGs because PNG uses lossless compression. The tradeoff is perfect quality with no compression artifacts.
Can I add transparency after converting?
The conversion preserves the image as-is (no transparency is added). To add transparency, open the converted PNG in an image editor and remove the background.
