Image Format Converter

Convert any supported image into PNG, JPG, WebP, AVIF or BMP, with a quality slider for the lossy formats.

How to use the Image Format Converter

  1. Add the images you want to convert.
  2. Choose the output format from the dropdown.
  3. Set the quality slider if the format you picked is lossy.
  4. Press Convert, then download the files individually or as one ZIP archive.

One converter for every common format

This tool reads JPG, PNG, WebP, AVIF, BMP, GIF and SVG files and writes PNG, JPG, WebP, AVIF or BMP. The dimensions are always preserved; only the encoding changes.

Which format should you choose?

  • PNG — lossless, supports transparency. Best for logos, icons, screenshots and line art.
  • JPG — lossy, no transparency, understood by everything. Best for photographs.
  • WebP — smaller than both at similar quality, supports transparency, works in every current browser.
  • AVIF — usually the smallest of all, but only some browsers can write it. The tool tells you when yours cannot.
  • BMP — uncompressed, very large, useful only for older Windows software.

Things worth knowing

Transparency survives a conversion to PNG, WebP or AVIF and is replaced by a white background when the target is JPG or BMP. Converting from a lossy source to a lossless format does not restore lost detail — it just stops any further loss. And converting never changes the width or height, so use a resizer if you also need different dimensions.

Frequently asked questions

Which formats can I convert from?
JPG, PNG, WebP, AVIF, BMP, GIF and SVG can be read. Output is available as PNG, JPG, WebP, AVIF or BMP.
Why is AVIF sometimes unavailable?
Writing AVIF depends on an encoder built into the browser, and not every browser has one. When yours cannot write the format, the tool says so instead of producing a broken file.
Does converting change the image size?
The pixel dimensions stay the same. The file size changes, because each format compresses differently.
