How to use it

  1. Choose the format you want to convert to.
  2. Choose your images, or drag them onto the box.
  3. Download each converted file, or all of them as a ZIP file.

Which format should I choose?

JPG for photographs you want to share or send: small files that open everywhere. PNG for screenshots, logos and anything with sharp text or see-through areas. WebP for pictures going on a website, because it is smaller than either.

What can it open?

JPG, PNG, WebP, GIF and BMP open in every current browser. HEIC photos from iPhones open using a converter built into this page. AVIF opens in current versions of Chrome, Edge, Firefox and Safari. Animated GIFs and WebPs convert to a still picture of the first frame.

TIFF files open using a picture engine of about 5 MB, which is downloaded only when you choose a TIFF. Only the first page of a TIFF with several pages is converted here; to convert every page, use TIFF to JPG. SVG drawings are drawn at their own size; for a larger size, use SVG to PNG.

Many files at once?

For a whole folder, see Batch image converter: the same tool, with a worked example for large batches.

Questions

Are my files uploaded?

No. The work happens inside your web browser, on your own device. Before your file is opened, this page locks itself: from then on your browser refuses to let it fetch, upload or send anything at all. You can check: once the page has loaded, switch off your internet connection and it will still work. How the lock works.
