Image Tools

Most image tools ask you to upload your photo to their server first. That is a strange trade for a job your own device can do in under a second, and it means a picture of your home, your children or your passport now lives on someone else’s disk.

These tools do the work locally. The compressor re-encodes a JPEG, PNG or WebP at a quality you choose and shows you the before and after size; the resizer changes dimensions with the aspect ratio locked, or by percentage. The converter goes between JPEG, PNG, WebP and AVIF, and asks for a background colour before flattening transparency rather than quietly compositing onto black. The cropper works from the keyboard as well as from a pointer, and the favicon generator turns one image into every size a browser, an iOS home screen and a web app manifest ask for.

All of them respect EXIF orientation, so portrait photos come out upright, and all of them strip metadata such as GPS coordinates in the process, which is a privacy improvement worth knowing about.

There are real limits, and they exist to protect your device. Files are capped at 25 MB and images at 40 megapixels, checked by reading the file header before anything is decoded: a small file can declare enormous dimensions, and decoding one of those is how a browser tab runs out of memory and dies.
