Image guides
Questions that come up around the tools, answered properly. Each one leads with the answer, then explains it for anyone who wants to know why.
How to compress an image for email
Aim for about 1 MB per photograph. That is comfortably inside every common limit even with several attached, and still looks sharp on a full screen. Drop to 500 KB if you are sending a batch, or if the recipient is on a corporate mail server.

How to compress an image without losing quality
For photographs, use JPEG at quality 80-90, or convert to WebP. You will typically save 60-80% with no difference visible at normal viewing size. Genuinely lossless compression only saves about 5-20%, and only for PNG.

Why PNG files are so large
PNG is lossless: it stores every pixel exactly, so it cannot throw away detail to save space. To make one smaller, either reduce how many distinct colours it stores - which is lossless for what remains and very effective on screenshots - or convert to JPEG or WebP if the image is a photograph.

What your photos reveal about you
Most phone photographs contain GPS coordinates accurate to a few metres, plus the camera model and a timestamp. Removing the metadata deletes all of that. It does not change what is visible in the picture itself.

How to resize images for a website
Resize to roughly twice the width it will be displayed at - 1600px wide for an 800px slot, to stay sharp on high-density screens - then compress to under 200 KB. Use WebP where you can, JPEG otherwise.
