Image Format Converter

Convert images between PNG, JPEG and WebP in your browser. Pick a format, see the size before you save, and upload nothing anywhere.

How to use the Image Format Converter

  1. Drop your image. Drag a file in, or click to choose one from your device.
  2. Pick a format. Choose PNG, JPEG or WebP, and set the quality if it applies.
  3. Download. Save the converted copy under its new extension.

Frequently asked questions

Which format should I use?
WebP for almost anything on the web, since it beats both of the others at the same visual quality. JPEG for photographs where the widest possible compatibility matters. PNG only when you need transparency or exact pixels, such as a screenshot or a logo.
Why did my transparent background turn white?
JPEG has no alpha channel and cannot store transparency at all. Anything transparent has to become a solid colour, and white is the least surprising choice. Convert to PNG or WebP instead if the transparency matters.
Why is my converted PNG larger than the JPEG it came from?
PNG is lossless, so it stores every pixel exactly, while JPEG discards detail to save space. Converting a photograph from JPEG to PNG cannot recover what was already thrown away, and it stops compressing what remains.
Can this convert HEIC or AVIF files?
It can usually open them, because browsers decode more formats than they can write. It cannot save to them: a browser canvas encodes only PNG, JPEG and WebP, so those are the three offered rather than promising a conversion that would silently produce a PNG.
