How to use
- Choose the image you want to convert.
- Select the output format — JPG, PNG or WebP.
- Press Convert and download the new file.
How it works
The image is drawn onto a browser canvas and re-encoded in the chosen format. JPG gives the smallest files for photos, PNG keeps sharp edges and transparency, and WebP usually gives the best size-to-quality balance. Transparent areas become white when converting to JPG, because JPG has no transparency.
Worked example: Example: a 1.2 MB PNG screenshot typically converts to a JPG of about 150–250 KB at quality 0.92.
Frequently asked questions
Which format is smallest for photos?
WebP is usually smallest, with JPG close behind and universally accepted. PNG is best for screenshots, logos and images with transparency.
Why did my transparent image get a white background?
JPG and (in this tool) flattened WebP do not keep transparency in the same way; transparent pixels are placed on white. Choose PNG output to keep transparency.
Is there a file size limit?
There is no server limit because nothing is uploaded. Very large images (50 MP+) may be slow on older phones.
Are my images uploaded?
No. Conversion happens in your browser; your files never leave your device.
