The problem
You have a PNG screenshot and you need a JPG for a form that only accepts JPEG. Or you downloaded a WebP image from a website and your old image editor can't open it. Or your designer sent you a file in the wrong format and you don't want to bother them about it.
Image format conversion is one of those tasks that should take five seconds but somehow requires either installing software or uploading your file to a random website.
How it works
- Upload your image — the tool auto-detects the source format (PNG, JPG, or WebP).
- Pick the target format — select PNG, JPG, or WebP from the dropdown.
- Adjust quality — for lossy formats (JPG, WebP), a quality slider lets you balance file size against visual quality.
- Download — the converted file downloads with the correct extension.
No server involved. The conversion uses your browser's built-in Canvas API, which supports all three formats natively.
When to convert
PNG to JPG: When you need a smaller file and don't need transparency. Common for uploading photos to forms, CMS platforms, or email.
JPG to PNG: When you need transparency support or lossless quality. Rare for photos, but useful if you're going to edit the image further and don't want cumulative JPEG artifacts.
Anything to WebP: When you're optimizing for the web. WebP gives you smaller files than both PNG and JPG with comparable quality. All modern browsers support it.
WebP to JPG/PNG: When you need compatibility with older software, or when a platform doesn't accept WebP uploads. This is the most common conversion people search for — they saved an image from the web and can't use it elsewhere.
