Image Format Converter

Convert many images at once

Drop up to 50 images on the page, choose the format you want and every file is converted straight away. Download them one by one or all together in a zip. The converter reads PNG, JPG, WebP, GIF, SVG, AVIF and BMP files, as far as your browser can open them.

Which format fits which job

• PNG is lossless and keeps transparency. Choose it for logos, icons, screenshots and anything with sharp text. Photos saved as PNG are very large.
• JPG is the universal photo format. It works everywhere, but has no transparency and shows artefacts if the quality is set too low.
• WebP gives photos that are about 25 to 35 percent smaller than JPG at the same look, and supports transparency. All current browsers display it.
• AVIF is the newest and usually the smallest, but it is slow to encode and not every browser can create it.

About AVIF support

Your browser decides whether it can write AVIF. This page checks that for you. If your browser cannot, an explanation appears and the AVIF option does nothing instead of quietly producing something else. A recent desktop Chrome or Edge can do it.

Steps

1. Add your images.
2. Choose the output format.
3. For JPG, WebP and AVIF set the quality. 80 to 90 is a good balance; below 60 you will often see blocks and blur.
4. For JPG, pick a background colour for any transparent areas.
5. Download.

Good to know

• Animated GIFs become still pictures showing the first frame.
• SVG files are drawn at their natural size. If they have no width and height they come out at a default size, so use the SVG tool on this site when you need a specific scale.
• File names are kept and only the extension changes.
• Everything happens locally in your browser, so private pictures stay private.
