How to Convert an Image to PNG, JPG or WebP
Sometimes you have an image in the wrong format — a PNG that's too heavy, a WebP a program won't open, or a JPG you need transparent. Converting between formats fixes this in seconds. This guide explains the differences between the main image formats and shows you how to convert one to another for free.
PNG vs JPG vs WebP
- JPG (JPEG) — best for photographs. Small file size, but no transparency and slight quality loss.
- PNG — best for logos, screenshots and graphics that need transparency or crisp edges. Larger files.
- WebP — a modern format that is smaller than both JPG and PNG at similar quality. Ideal for websites, though a few older programs don't support it.
Which format should you choose?
For a photo you want to email or post, choose JPG. For anything with a transparent background or sharp text, choose PNG. For a fast-loading website, WebP gives the best balance of quality and size.
Step-by-step: convert an image
- Open the Image Converter.
- Upload your image by dragging it in or clicking to browse.
- Choose the format you want to convert to.
- Click Convert and download the new file.
A note on transparency
JPG does not support transparency. If you convert a transparent PNG to JPG, the see-through areas are filled with a solid background (usually white). Keep the file as PNG or WebP if transparency matters.
Frequently Asked Questions
Does converting reduce image quality?
Converting to PNG or WebP is lossless or near-lossless. Converting to JPG applies compression, which is fine for photos but not ideal for sharp graphics.
Can I convert HEIC photos from my iPhone?
Browser support for HEIC varies. If your browser can display the image, it can usually convert it; otherwise convert HEIC to JPG on the phone first.
Is there a limit on file size?
No fixed limit — conversion happens in your browser, so only your device's memory matters.
Are my images uploaded?
No. Everything is processed locally and your images never leave your device.
Is it free?
Yes, completely free with no sign-up or watermark.
