What Image Converter does
Image Converter changes a picture from one format to another: JPG, PNG or WebP. Choose the target format, optionally set a maximum width or height, adjust the quality for JPG and WebP, and download the converted file. The conversion runs in your browser.
How to convert an image
- Add the image you want to convert.
- Choose the format to convert to.
- Optionally enter a maximum width or height; the picture is scaled down to fit and keeps its proportions.
- Set the quality for JPG or WebP output.
- Press Convert image and download.
Which format should you choose?
| Format | Strengths | Weaknesses | Choose it for |
|---|---|---|---|
| JPG | Small files, accepted everywhere | No transparency; loses a little quality on each save | Photographs, form uploads |
| PNG | Lossless, supports transparency, crisp edges | Large files for photos | Logos, screenshots, graphics with text |
| WebP | Smaller than JPG at similar quality, supports transparency | Not accepted by some forms and older software | Websites and apps |
Typical conversions
- PNG to JPG: a screenshot or scan is too large, or a form accepts JPG only.
- WebP to JPG or PNG: a picture saved from a website will not open in an older program.
- JPG to PNG: a design tool needs PNG, or you want to stop further quality loss while editing.
- JPG or PNG to WebP: you are optimising a website.
- GIF, BMP or AVIF to JPG or PNG: making an unusual file usable. Only the first frame of an animated GIF is converted.
What happens to transparency
JPG cannot store transparent areas. When you convert a transparent PNG or WebP to JPG, those areas are filled with white, and the result card says so. PNG and WebP output keep transparency.
Does converting improve quality?
No. Converting a JPG to PNG keeps the picture exactly as it is — including any compression artefacts already there — and makes the file bigger. Convert to PNG to prevent further loss, not to restore quality.
Good to know
- The converted file contains the picture only. Camera data and location stored in the original are not copied.
- Use the maximum width or height to convert and scale down in one step, which is handy for web images.
- iPhone HEIC photos need a dedicated decoder: use HEIC to JPG Converter.
- To turn images into a document, use JPG to PDF; to get pictures out of a PDF, use PDF to JPG.
