Free Universal Image Converter: Change Any Image Format (JPG, PNG, WebP, GIF) Online

Introduction

“File format not supported.”

You pick a nice photo, upload it to a website, and… error. Maybe it’s a WebP from your browser, or a HEIC photo from your iPhone, and the site only accepts JPG. Or you need a transparent PNG logo, but all you have is a JPG on your desktop.

You shouldn’t need Photoshop or weird software just to change a file type.

That’s exactly what the PicDitt Universal Image Converter is for. It runs in your browser, it’s free, and it lets you convert between formats like JPG, PNG, WebP, and GIF in a few clicks.

Before we jump into the tutorial, here’s a quick guide on when to use each format.

Quick Format Guide: JPG vs PNG vs WebP vs GIF

You don’t need to be a designer to pick the right format. Think about what the image is for:

• JPG (JPEG): Best for photos and social media. Small file size, good quality. (Note: Does not support transparent backgrounds).
• PNG: Best for logos, icons, and text. Supports transparency, so your logo can float over any background.
• WebP: Best for websites. It usually gives you smaller files than JPG/PNG at better quality, making pages load faster.
• GIF: Best for simple animations and tiny loops.

Once you know the target format you need, the rest is easy.

How to Convert Any Image Format (Step-by-Step)

You don’t need an account, and there’s no paywall.

Step 1: Upload Your Image

Click the Upload button and select your file (JPG, PNG, WebP, GIF, HEIC, etc.) from your device. The tool will load the file directly inside your browser.

Step 2: Check Dimensions & Size

As soon as the image loads, PicDitt shows you the current dimensions and file size at the top (e.g., 3024 × 4032 pixels | 3.1 MB).
This is useful to confirm you uploaded the right file or to see if the image is too huge before converting.

Step 3: Select Your Target FormatChoose what you want to convert to from the buttons:

• Convert to JPG for general compatibility.
• Convert to PNG for logos/transparency.
• Convert to WebP for website speed.
• Convert to GIF for animations.

Step 4: Convert and Download

Hit Convert. In a moment, you’ll get a download button for your new file.
Your converted image keeps the same visual content, just in the new format.

Your Images Stay Private

Most “free online converters” upload your file to their server, process it remotely, and send it back. That means your private photos sit on someone else’s computer.

PicDitt is different. The Universal Image Converter runs entirely inside your browser using modern web technology.

• Your images are not uploaded to a server.
• Conversion happens locally on your device (CPU).
• When you close the tab, the tool no longer has access to your files.
