Image Format Converter

Convert images between JPG, PNG, WebP, and AVIF in bulk, right in your browser. Common conversions include JPG to PNG, PNG to JPG, PNG to WebP, WebP to PNG, JPG to WebP, and PNG to AVIF — and GIF or BMP files convert too. Add as many files as you like, pick a target format and quality, then download each result or all of them as a ZIP. Modern formats like WebP and AVIF can shrink files dramatically — and nothing is ever uploaded.

How to use Image Format Converter

  1. Drop in one or more images (JPG, PNG, WebP, AVIF, GIF, BMP).
  2. Choose the target format and, for lossy formats, a quality level.
  3. Click Convert, then download images individually or grab the whole batch as a ZIP.

Frequently asked questions

How do I convert JPG to PNG?
Add your JPG files, choose PNG as the target format, and click Convert. PNG is lossless, so the result keeps full quality.
How do I convert PNG to JPG?
Upload the PNG, select JPG as the target, and set a quality level. JPG has no transparency, so transparent areas are filled with white.
How do I convert PNG to WebP?
Drop in the PNG, choose WebP as the target, and download. WebP keeps transparency and is usually much smaller than PNG.
Are my images uploaded to a server?
No — conversion uses the browser canvas locally, so your images never leave your device.
Why is the AVIF (or WebP) option sometimes disabled?
Encoding support depends on your browser. The tool detects whether it can actually output each format and disables any it can\u2019t — AVIF export needs a recent Chromium or Firefox.
Which format should I pick?
AVIF usually gives the smallest files, WebP is a great widely-supported balance, JPG suits photos where compatibility matters, and PNG is lossless for graphics and transparency.
Does converting to JPG lose transparency?
Yes — JPG has no alpha channel, so transparent areas are filled with white. Use PNG, WebP, or AVIF to keep transparency.
