What is Image Format Converter?
Different image formats suit different needs: PNG preserves sharp edges and transparency, JPG compresses photographs efficiently, and WebP offers excellent quality at smaller sizes. An image format converter lets you switch a picture between these formats so you always have the right one for the job.
This tool converts entirely in your browser using the HTML canvas, with a quality control for the lossy JPG and WebP formats.
How to Use the Image Format Converter
- Upload the image you want to convert.
- Choose the target format: PNG, JPG or WebP.
- Adjust the quality for JPG or WebP if desired.
- Click Convert, then Download the new image.

Benefits & Use Cases
Web developers switch to WebP for faster pages, designers export transparent PNGs, and users convert photos to JPG for easy sharing. Choosing the right format improves quality, reduces file size, or both.
Since conversion happens locally, your images stay private and there is no upload wait.
The Image Format Converter is completely free, needs no sign-up or installation, and runs entirely in your browser — nothing you enter is uploaded to a server, so your data stays private. It works on desktop, tablet and mobile, in light or dark mode.
Tips & Best Practices
Choose the format for the job: PNG for graphics and transparency, JPG for photographs, and WebP for the smallest web-ready files at good quality. Converting to JPG fills transparent areas with white, since JPG has no transparency. WebP support depends on your browser — if it is unavailable, fall back to PNG or JPG.
Resize or compress the result with the Image Resizer, or crop it down first with the Image Cropper.
FAQ about Image Format Converter
Which format should I choose?
Use PNG for graphics and transparency, JPG for photographs, and WebP when you want smaller files with good quality for the web.
Why does JPG lose transparency?
JPG does not support transparency, so transparent areas are filled with a white background during conversion.
Is WebP supported everywhere?
WebP conversion depends on your browser. All modern browsers support it, but if yours does not, try PNG or JPG instead.
Are my images uploaded?
No. The conversion runs on a canvas in your browser, so your images never leave your device.
