How to

How to use Image Converter

  1. 1

    Add your pictures

    Drop PNG, JPG, WebP or HEIC files onto the page, or pick them from your computer. More than one at a time is fine.

  2. 2

    Choose the output

    Pick PNG, JPG or WebP with the output switch. For JPG and WebP, set the quality slider; lower numbers mean a smaller file.

  3. 3

    Download

    Save the converted files to your device. Each one keeps its name and gains the extension of the format you chose.

Questions

Frequently asked questions

Which formats can this read and write?

It reads PNG, JPG, WebP, HEIC and HEIF, and writes PNG, JPG or WebP. SVG, PDF and animated files are not handled here.

What happens to a transparent PNG?

JPG has no transparency, so those areas are filled with the background color the converter uses. Choose WebP or PNG output when the transparency has to survive.

Which output should I pick?

WebP is the smallest of the three for photographs and every current browser reads it. JPG is the safer choice for older software. PNG keeps a lossless copy and any transparency.

Can I convert a JPG back into a PNG?

Yes, but the detail JPG discarded does not come back. A PNG made from a JPG is a lossless copy of a lossy picture, at a larger size.

How many images can I add at once?

There is no fixed limit. Past about 500 MB the page warns you before it starts. Files with the same name get a number added inside the ZIP. Older browsers are told plainly that they cannot run this.

Can I get a photo under an exact size, like 200 KB?

Yes. Switch the quality control to target size, type 200 and pick KB. The page tries a range of quality settings and keeps the best one that lands under your figure.

Background

What converting a picture actually changes

Add files, choose the format you want out, and set the quality when the output is JPG or WebP. PNG, JPG, WebP, HEIC and HEIF are all read; the output is PNG, JPG or WebP.

  • A format decides how pixels are stored, not what they show. Converting rewrites the storage and, for JPG and WebP, drops detail while doing it.
  • PNG holds every pixel exactly and supports transparency, which makes it right for logos, screenshots and line art.
  • JPG and WebP throw away detail the eye is poor at noticing, which is why photographs come out far smaller in them.
  • Converting the same picture back and forth between lossy formats loses a little each time, so keep one original to work from.
