Convert an image to JPG, PNG, or WebP in the browser. Use WebP for smaller web uploads, PNG when you need a lossless file, and JPG for the most compatible photo format.
Image format converter
Convert a photo to JPG, PNG, or WebP in your browser. Useful for shrinking PNGs to WebP before upload, or turning a screenshot into a JPG. The file is never uploaded.
Pick the format first, then choose the file. PNG ignores quality (it is lossless). HEIC iPhone photos should go through the HEIC to JPG tool first.
How to use Image format converter
- Choose the output format (and quality for JPG/WebP).
- Select an image file from your device.
- Preview the result and download it.
Example: A 2 MB PNG screenshot often becomes a few hundred KB as WebP at quality 0.86.
Frequently asked questions
- Will this convert iPhone HEIC photos?
- Most browsers cannot decode HEIC in an <img> tag. Convert HEIC to JPG first with the HEIC to JPG tool, then convert that JPG to WebP here if you want.
- Why is PNG quality ignored?
- PNG is lossless. Quality only applies to JPG and WebP, which discard detail to save space.
- Is the image uploaded?
- No. Conversion uses the canvas API on your device.
