Why does a form ask for 300 DPI?

300 DPI is the standard for printing, so offices and portals often ask for it. The tool writes that value into the JPG or PNG file.

Is this tool free and private?

Yes. It is free with no limits, sign-up or watermark, and your images are processed inside your browser — nothing is uploaded to a server.

Which image formats are supported?

You can open JPG, PNG, WebP, HEIC, AVIF, GIF, BMP, SVG, TIFF, PSD, ICO, TGA, JPEG XL and camera RAW files, and save the result as JPG, PNG, WebP, AVIF and more.
