Every image format has a job. JPG is small and universal, PNG keeps sharp edges and transparency, WebP is smaller than both for the web. When a site, app or printer asks for a different format, you don't need new software — PixKitTools' Image Format Converter switches JPG, PNG, WebP and AVIF in your browser, free and in bulk.

JPG vs PNG vs WebP — which one to pick?

  • JPG — best for photographs. Small files, works everywhere, but no transparency and every save loses a little quality.
  • PNG — best for logos, screenshots and graphics with sharp edges or text. Lossless, supports transparency, but photos become much bigger files.
  • WebP — best for websites. About 30% smaller than JPG at the same quality, with transparency support.
  • AVIF — even smaller than WebP, but not every old app opens it yet.

Convert in 4 steps

  1. Open the Image Format Converter.
  2. Upload one image, or many at once.
  3. Choose the output format — JPG, PNG, WebP or AVIF — and set the quality for JPG and WebP.
  4. Download one file, or the whole batch as a ZIP. Everything happens in your browser, so your images are never uploaded.

Three honest notes

  • Converting JPG to PNG does not restore quality the JPG already lost. It only stops further loss from that point on.
  • A photo saved as PNG is often 3–5 times bigger than the same photo as JPG. Use PNG for graphics, not for photos.
  • JPG cannot store transparency. If your PNG has a transparent background and you convert it to JPG, the transparent area becomes white.
