How to use Convert image
- Choose the images to convert. Any format your browser can open works.
- Pick the new format: JPG, PNG, WebP or AVIF.
- Select Convert.
- Download one image, or all of them in a zip.
Which format to choose
JPG suits photographs and works everywhere, but has no transparency. PNG is lossless and keeps transparency, which suits screenshots, logos and graphics with sharp edges, but makes large files for photos. WebP does both jobs at smaller sizes and works in every current browser, which makes it the best choice for websites. AVIF compresses best of all, but not every browser can save it yet.
What the conversion does
Each image is decoded by your browser, turned the right way up, and saved in the new format at high quality. Transparent areas become white when converting to JPG, since JPG can't store transparency. Metadata such as GPS location is not carried over, so converted photos are also safer to share.
If your browser can't save the format you picked, the tool tells you instead of handing you a PNG with the wrong file extension. The file extension of every converted image matches its real format.
What happens to your images
Conversion happens in a background worker in this browser tab, using the browser's own image codecs. Nothing is uploaded and nothing is stored. Convert many images at once and they download together as a zip, named after the originals with their new extension.
Common uses
Turning WebP images saved from a website into JPG so an older program can open them, converting PNG screenshots to JPG to shrink an email, making WebP or AVIF versions of photos for a faster website, or converting a logo to PNG to keep its transparent background. A whole folder of images can be converted in one go.
Limits
The input can be any image your browser can open: JPG, PNG, WebP, GIF, BMP and AVIF, plus HEIC photos from iPhones in every browser, decoded by libheif loaded from this site. Animated GIFs and WebPs keep only their first frame. Quality is set high, at 90, for lossy formats; to make files smaller, use Compress image afterwards.
Questions
- What happens to transparency when converting to JPG?
- JPG can't store transparency, so transparent areas become white rather than black.
- Why can't I save AVIF?
- Saving AVIF needs browser support that not every browser has. If yours can't, the tool says so instead of giving you a PNG with the wrong name.
- Are my images uploaded?
- No. Conversion happens in your browser using its own image codecs.
