Every image format makes a different trade-off between quality, file size and compatibility. PNG keeps crisp edges and transparency but stays heavy; JPG shrinks photos at the cost of fine detail; WebP and AVIF cut size further for the web but still trip up older software. Our free image converters let you move between all of them in seconds — PNG, JPG and WebP both ways — without installing anything. Every conversion runs entirely in your browser using the Canvas API, so your photos never leave your device, never get uploaded to a server, and never sit in someone else's queue. No signup, no watermark, no daily cap. Drop a file in, pick the target format, and download.

Frequently asked questions

Do my images get uploaded anywhere?

No. Image conversion happens locally in your browser tab. The file is read into memory, converted, and offered back as a download — nothing is sent to a server, so even confidential screenshots and personal photos stay on your device.

Which image format should I convert to?

Use JPG for photographs you want small, PNG when you need transparency or razor-sharp text and logos, and WebP when you want the smallest file for a website while keeping good quality. If you are unsure, JPG is the safest universal choice.

Can I convert several images at once?

Yes. Most of our image tools accept multiple files in one batch and hand them back together, so you can convert a whole folder of screenshots or photos in a single pass.
