How this result is produced

The browser decodes the source and writes a new JPG, PNG, or WebP file. When transparent pixels are converted to JPG, the selected background is applied because JPG has no transparency channel.

Practical example

A transparent signature can stay transparent in PNG or WebP. If a portal requires JPG, choose a white background before conversion because JPG cannot store transparency, then reopen the output to check edges and any faint strokes. Check the portal’s accepted format list rather than assuming WebP is supported.

Limits and troubleshooting

  • JPG cannot preserve transparency.
  • PNG export is lossless at the encoder level but source decoding and canvas color handling can normalize data.

If a format is unavailable, that encoder may not be supported by the current browser; try PNG or JPG instead. A file that will not preview should be opened and saved again in a trusted image editor before another conversion attempt.

Questions people ask

Which format is smallest?

It depends on the image. WebP and JPG are often smaller for photographs; PNG is often better for flat graphics and transparency.

Conversion changes encoding, not source quality

Changing a filename extension does not convert the image. This tool decodes the input and produces a new file, then checks the encoded signature and dimensions. JPG fills transparent pixels; PNG and WebP retain existing transparency. It does not remove an opaque photographed background.

Re-encoding can normalize color and removes source metadata. Turning a previously compressed JPG into PNG cannot restore lost detail. Animated PNG and WebP are rejected; export a still image first. HEIC, SVG, GIF, RAW, and TIFF are outside the supported input list.
