Which format should I pick?

Use WebP for websites, JPG for sharing and printing, and PNG when you need transparency or crisp text.

Does converting to PNG improve a blurry JPG?

No. Detail lost by earlier compression cannot be recovered.

Is there a file size limit?

You are only limited by your device's memory, so very large photos may be slower on older phones.

About this tool

Each format has a purpose: JPG for photographs, PNG for graphics and transparency, WebP for fast-loading web pages. This tool moves a picture between all three.

Conversion happens on a canvas in your browser, so the original file is never uploaded anywhere.
