Image Format Converter Questions & Answers

What quality setting should I use?
Around 80 percent keeps photos looking the same to most eyes while cutting the size a lot.
Will a transparent PNG stay transparent?
In PNG and WebP, yes. JPG has no transparency, so transparent areas are filled.
Why is my PNG bigger than the JPG?
PNG stores every pixel without loss. For photos that is wasteful; use JPG or WebP instead.
Are my images uploaded?
No. They are converted in your browser.

Lighter Images, Faster Pages

Images make up most of the weight of a typical web page, and oversized photos slow down emails and uploads too. An image format converter with a quality control solves both problems.

A simple rule of thumb

  • Photos: WebP or JPG at about 80 percent.
  • Screenshots, logos, text: PNG or WebP.
  • Anything with transparency: PNG or WebP.

Size matters as much as format

A 4000 pixel wide photo shown 800 pixels wide wastes most of its data. Resize it first with the Social Image Resizer. iPhone photos in HEIC format? Use the HEIC Photo Converter. Sharing photos publicly? Remove hidden location data with the EXIF & GPS Remover.
