About SynoxTools

SynoxTools is a collection of free online image tools with a simple mission: make basic image editing fast, private, and accessible to everyone — without uploads, accounts, or paywalls.

Every tool on this site runs 100% in your browser. Your files never leave your device — there are no server uploads, no tracking pixels, and no analytics on image content. We believe privacy isn't a feature, it's a right.

The project started when the founder needed to compress a batch of photos for a website and realized every "free" compressor wanted to upload them to a server. SynoxTools was built to solve that: client-side compression, resizing, format conversion, cropping, and watermarking — all running locally in your browser.

The tools are and will always be free. No hidden fees, no "premium" tiers for basic features, no sign-up walls. The source code is openly available — you can download it from the link in the footer and run it on your own machine.
