How to convert an image format
Converting an image from one format to another changes how the pixel data is encoded and stored. Different formats have different strengths — follow these steps to convert your image with ImageToolsFree:
When to use each format
Choosing the right image format depends on what you're using the image for. Each format has specific strengths and weaknesses that make it more or less suitable for different situations.
Use JPG for photos: JPG is the most widely supported format and works best for photographs and complex images with many colors and gradients. It uses lossy compression to achieve small file sizes, making it ideal for web images where bandwidth matters. The quality loss at 80–90% is virtually invisible.
Use PNG for logos and graphics: PNG uses lossless compression, meaning no quality is lost. It also supports transparency, making it the correct choice for logos, icons, and graphics that need a transparent background. PNG files are larger than JPG but retain every pixel perfectly.
Use WebP for everything on the web: WebP is Google's modern format that combines the best of JPG and PNG — smaller file sizes than JPG with support for transparency like PNG. It produces files 25–35% smaller than equivalent JPG images, and is supported by every modern browser.
Frequently asked questions
What is the difference between JPG, PNG and WebP?
JPG is best for photographs and complex images — it compresses well but loses some quality. PNG is lossless and supports transparency, making it ideal for logos, icons, and graphics. WebP is a modern format that offers the best of both — smaller file sizes than JPG with optional transparency like PNG.
Will converting to PNG make my file larger?
Yes, usually. PNG is a lossless format so it retains all pixel data, which results in larger file sizes compared to JPG. If file size matters more than transparency, use JPG or WebP instead.
Does converting lose image quality?
Converting to PNG is lossless — no quality is lost. Converting to JPG uses the quality setting you choose — at 80–90% the difference is virtually invisible. Converting to WebP uses an optimized internal quality setting that balances size and quality automatically.
Can I convert a transparent PNG to JPG?
Yes, but JPG does not support transparency. Any transparent areas will be filled with white when converting to JPG. If you need to keep transparency, convert to PNG or WebP instead — both support transparent backgrounds.
Why should I use WebP?
WebP images are typically 25–35% smaller than equivalent JPG images at the same visual quality. This makes them ideal for websites where fast loading times and bandwidth savings matter. All modern browsers including Chrome, Firefox, Safari and Edge support WebP.
Are my images kept private?
Yes. All conversion happens entirely within your browser. Your images are never uploaded to any server, never stored, and never accessible to anyone else. This tool is safe to use with sensitive or confidential images.
Can I convert multiple images at once?
Yes. Switch to "Bulk Convert" mode at the top of the tool to convert up to 20 images at once, then download them together as a single ZIP file.
What happens to the image dimensions when I convert?
Converting a format does not change the image dimensions — the width and height stay exactly the same. Only the file encoding changes. If you need to change dimensions as well, use the Resize tool first and then convert the format.
