Image Converter

Convert images between JPG, PNG, and WebP formats online for free, instantly in your browser.

Overview

What is an image converter?

An image converter redraws an uploaded image and re-encodes it in a different file format — JPG, PNG, or WebP — without changing its dimensions, so you can match whatever format a specific platform, tool, or workflow requires.

Each format has different strengths: JPEG is widely supported and compact for photos, PNG supports transparency losslessly, and WebP often offers the best compression while still supporting transparency — making the right choice depend on what you need the image to do.

Tips

Best practices to keep in mind

A few things worth knowing before converting an image format.

PNG supports transparency while JPEG doesn't — converting a transparent PNG to JPEG fills the transparent areas with a solid background color instead of keeping them see-through.
WebP supports both transparency and strong compression, making it a good middle ground when you need a smaller file size without giving up a transparent background.
Converting between lossy formats like JPEG and WebP repeatedly compounds quality loss each time — always convert from the original source file rather than re-converting an already-converted copy.
Not every platform accepts every format — check that WebP is supported wherever you're uploading before switching your workflow away from the more universally supported JPEG or PNG.

FAQs

Frequently asked questions

Have questions about converting image formats? Here are the most common ones our users ask before getting started.

Is this image converter free to use?

Yes, the image converter is completely free with no signup, no usage limits, and no watermarks added to your images. It runs entirely in your browser, so there are no server costs passed on to you and no account is ever required to convert an image.

Does my image get uploaded to a server?

No. All conversion happens locally in your browser using the canvas API — your image never leaves your device or gets transmitted to any server. This makes the tool safe to use with private photos, unreleased designs, or confidential material.

What formats can I convert between?

You can upload a JPG, PNG, or WebP image and convert it into any of the other two formats. The tool reads the uploaded image, redraws it on a canvas, and re-encodes it in your chosen output format, all without changing the image's pixel dimensions.

Will converting from PNG to JPEG lose transparency?

Yes — JPEG doesn't support transparency, so any transparent areas in a PNG source image are filled in with a solid background when converted to JPEG. If you need to preserve transparency, convert to WebP or PNG instead, both of which support an alpha channel.

Does converting an image reduce its quality?

Converting to a lossless format like PNG preserves full quality, while converting to a lossy format like JPEG or WebP applies compression that can introduce minor quality loss, similar to saving a JPEG normally. For most images this loss is negligible, especially the first time an image is converted from its original source.
