How to use Convert image

  1. 1

    Drop in your pictures. JPG, PNG, WebP, AVIF, GIF and BMP files all work.

  2. 2

    Pick the format you need – JPG, PNG, WebP or AVIF.

  3. 3

    For JPG, WebP and AVIF, set the quality. For JPG you can also pick the colour that fills transparent areas.

  4. 4

    Press the convert button, then save the files one by one or as a single ZIP.

What this tool does

Convert image changes the file format of your pictures. It is the quick fix when a website refuses WebP, when a PNG screenshot is too heavy to send, or when you want modern formats like AVIF for your own site. Add as many files as you like and they are converted one after another.

Supported formats

From To
JPG, PNG, WebP, AVIF, GIF, BMP JPG, PNG, WebP, AVIF

JPG uses the MozJPEG encoder, WebP and AVIF use the reference libwebp and libavif encoders compiled to WebAssembly, and PNG output is optimised losslessly with OxiPNG.

Features

  • Batch conversion with a single ZIP download for the whole set.
  • Quality slider for the lossy formats.
  • Background colour for transparent images saved as JPG.
  • Photos keep their orientation: rotation stored in EXIF is applied before converting.

Limits

  • Animated GIF and animated WebP become a still image (first frame).
  • AVIF encoding takes noticeably longer than the other formats, especially on phones.
  • iPhone HEIC photos need the separate HEIC to JPG tool.
  • Embedded colour profiles and metadata such as camera details and GPS location are not copied to the new files.

Where your file is processed

This tool works in your browser: your file is processed on your own device, so it isn't sent to our server for this tool. Some other tools on UtiloNest do use our server, and their pages say so.

Frequently asked questions

Which format should I choose?

JPG when the picture has to open everywhere, including old software and printers. PNG for screenshots, logos and anything that needs sharp edges or transparency. WebP for websites, since it gives smaller files than JPG and keeps transparency. AVIF when you want the smallest file and know the place you use it supports AVIF.

What happens to transparent parts when I convert PNG to JPG?

JPG can't store transparency, so transparent pixels are filled with a solid colour. White is the default; you can pick any other colour, for example to match a dark website background.

Can I convert WebP files back to JPG or PNG?

Yes. That is a common reason to use this tool, because some apps and upload forms still reject WebP. Add the WebP files, choose JPG or PNG and convert.

Does converting lower the quality?

Converting to PNG is lossless. JPG, WebP and AVIF are lossy formats, so they discard detail you normally can't see; at 90% quality the difference is hard to spot. Converting a JPG to PNG will not bring back detail the JPG already lost.

Are animated GIFs supported?

A GIF is converted as a still picture using its first frame. Animation is not kept.
