Image Converter

How it works

Toolasy re-encodes each image to the format you choose using your browser's built-in canvas, entirely on your device. Convert PNG to JPG for smaller photos, WebP to JPG for compatibility, or JPG to WebP for the smallest files. Because nothing is uploaded, your images stay private and there's no upload wait. Need a smaller file or different dimensions? Try the Image Compressor or the Image Resizer.

Frequently asked questions

How do I convert an image to another format?

Drop your images, choose the target format — PNG, JPG or WebP — set the quality for lossy formats, and click Convert. One image downloads directly; several download as a ZIP. Everything happens on your device; nothing is uploaded.

Which conversions are supported?

Any direction between JPG, PNG and WebP — for example PNG to JPG, WebP to JPG, JPG to WebP, or PNG to WebP. Drop a mix of formats and convert them all to one target at once.

What happens to transparency when I convert to JPG?

JPG doesn't support transparency, so transparent areas are filled with a white background when you convert a PNG or WebP to JPG. Convert to PNG or WebP instead if you need to keep transparency.

Are my images uploaded to a server?

No. Everything runs locally in your browser. Your images are never uploaded, stored, or sent anywhere — open your Network tab to confirm zero traffic.

Which format should I choose?

JPG is best for photos and small file sizes, PNG keeps sharp edges and transparency, and WebP usually gives the smallest file at similar quality. Use the quality slider to balance size and detail for JPG and WebP.
