Questions

Need to resize for social media? Use the image resizer.

Is this image converter free?

Yes. No sign-up, no watermark on your images and no limit.

Which formats can I convert to?

JPG, PNG and WebP. Most common inputs are supported, including HEIC photos your browser can open.

Are my images uploaded?

No. Your browser converts them, so files never leave your device.

How do I make an image smaller in KB?

Turn on "Target size" and choose a limit. The tool lowers quality just enough to fit under it.

Should I use JPG, PNG or WebP?

JPG for photos, PNG for logos, screenshots and sharp text, WebP for the smallest files on websites.

Can I keep the original size?

Yes. Choose "Keep original size" and only the format and quality change.

Can I convert many images at once?

Yes. Add a batch and download them all as a ZIP.

Does converting reduce quality?

PNG is lossless. JPG and WebP use the quality setting, so 80–90% usually looks identical at a much smaller size.
