Compressing images
Make images smaller for email, web and uploads — hit a target size without visibly wrecking quality.
Compression is a negotiation between file size and visible quality, and the right answer depends entirely on where the image is going. A hero image on a web page can lose detail a viewer will never notice; a photo you are printing cannot. An email attachment has a hard megabyte ceiling; a portfolio piece has a quality floor. The guides here treat compression as that negotiation rather than a single "make it smaller" button.
They all run on the EditItAll compressor, which re-encodes images with professional-grade codecs right on your device — no upload, no watermark, no per-file limit — and they cover the two questions people actually have. The first is "how do I hit a specific size", like getting a 12 MB photo under a 5 MB upload cap, which is about choosing a format and a quality level deliberately. The second is "how do I shrink this without it looking obviously worse", which is about understanding what each format throws away: JPEG discards fine color and high-frequency detail, PNG stays lossless but only shrinks flat graphics well, and modern formats like WebP and AVIF often beat both at the same visible quality.
Because it all happens locally, you can compress a whole folder of images without any of them leaving your machine — the point of the tool as much as the point of these guides.
