The image converter changes a picture to JPG, PNG or WebP. It accepts JPG, PNG, WebP, HEIC, AVIF, GIF and BMP as input. When a site refuses an image you want to upload, or a program will not open it, changing the format often solves the problem.
The conversion happens in your browser and the pictures never leave your device. You can add several files at once.
How to use
- Drop the images on the page or use the Choose images button. You can add more later with Add, up to 50 files.
- Under Output format pick JPG, PNG or WebP.
- For JPG and WebP set the Quality. PNG is lossless, so no quality setting appears.
- If you picked JPG, choose the Background colour. Transparent areas are filled with it, and white is the default.
- When conversion is done, press Download beside a row, or Download all to take everything.
- If a file cannot be read, an error note appears beside it and the others are not affected.
When it helps
Many forms and government systems accept only JPG. That is how you make a PNG screenshot or a WebP photo you downloaded uploadable. The reverse works too, and you can turn a logo into PNG to keep its transparency.
For people building websites, moving from JPG to WebP makes pages lighter. Converting an HEIC photo from an iPhone to JPG when it will not open on Windows is another very common need.
Tips
- JPG cannot hold transparency. If you convert a transparent PNG to JPG, the empty areas fill with the background colour you chose.
- Conversion re-encodes the picture, so EXIF data such as camera model and location is removed and colours are converted to sRGB.
- JPG suits photos, PNG suits graphics that need transparency, and WebP gives smaller files.
- Going from JPG to PNG does not shrink the file, it usually makes it bigger. PNG is lossless, but it cannot bring back quality that was already lost.
- If a very large photo hits the browser's size limit, it is scaled down when saved and the row carries a note saying so.
