PNG, JPEG, WebP, GIF, BMP, SVG… — multiple files supported

Supported conversions

Any format that the browser can decode (PNG, JPEG, WebP, GIF, BMP, ICO, SVG, AVIF on supported browsers) can be converted to PNG, JPEG, or WebP.

  • PNG — lossless; preserves transparency; largest file size.
  • JPEG — lossy; best for photos; no transparency (choose a background fill colour).
  • WebP — modern format; excellent quality-to-size ratio; supports transparency.

Quality setting

For JPEG and WebP the quality slider controls the encoder compression level (10 – 100 %). 85–92 % is a good default for photos. PNG is always lossless and ignores the quality setting.
