How to Make PNG Images Lighter by Converting Them to JPG

Published: Oct 19, 2026 | Updated: Oct 19, 2026 | About (Japanese)

Key points
  • Photo PNGs often shrink a lot as JPG
  • Transparent areas turn white
  • Text or diagram PNGs may show visible degradation

Screenshots and photos saved as PNG can get large.

Steps

  1. In "Convert Image Format", choose the PNG.
  2. Select "JPG" as the target format.
  3. Tap "Convert" and save.

Why it gets smaller

PNG saves without loss, which makes complex images like photos large. JPG removes information in ways that are hard to notice, so it ends up smaller.

Notes

To shrink further

Use "Compress & Resize Images" to lower quality or reduce image dimensions.

Use "Convert Image Format (JPG, PNG, WebP)" (free)
