About compressing images
A photo straight from a phone is often 4–8 MB, which is too big to email and far more than a website needs. Compressing usually cuts that by 70–90% with no visible difference.
How do I make a photo smaller to email it?
Most email providers cap attachments at 25 MB. Setting quality to about 80% and limiting the width to 1920 pixels will bring almost any phone photo under a megabyte, and it will still look sharp on any screen.
JPG, PNG or WebP — which should I use?
JPG for photographs. PNG for logos, screenshots, and anything needing a transparent background. WebP is smaller than JPG at the same visible quality and every current browser supports it, so it is the best choice for websites.
Does compressing reduce quality?
JPG and WebP are lossy, so some detail is discarded — but between 75% and 85% quality that loss is invisible in normal viewing. PNG is lossless and never degrades, which is also why it compresses far less.
Why did my file get bigger?
Because it was already compressed. Re-encoding an optimised JPG at high quality can add bytes rather than remove them. Lower the quality, reduce the width, or switch to WebP.
What actually saves the most space?
Resizing, usually. Dropping a 4000-pixel-wide photo to 1920 removes three quarters of the pixels before quality settings do anything at all.
