Guides
Short explainers on image formats, file size and privacy, to help you get more from our browser-based tools.
These guides explain the ideas behind the tools on this site in plain English, so you can make good decisions about your pictures instead of guessing. Each one is written for everyday jobs: putting photos on a website, attaching them to an email or an upload form, or sharing them without giving away more than you meant to.
Start with the format guide if you are unsure whether to save a picture as JPG, PNG or WebP. It explains which format suits photos, screenshots, logos and transparent graphics, and what to watch for when you convert. The guide to shrinking images walks through resizing to the size you need, picking a format, tuning the quality setting and avoiding repeated lossy saves. The EXIF guide covers the hidden details a camera or phone can store in a photo, such as the camera model, the time it was taken and sometimes the GPS location, why that matters for privacy, and how to remove it before you share.
Every guide links to the matching free tools. They all run in your browser, so your files stay on your device while you follow along.
