Frequently Asked Questions
Does Image Compressor upload my files to a server?
No. Image Compressor runs entirely in your browser using JavaScript and the Canvas API built into the browser itself — your files never leave your device or get sent to any Nabukit server.
Is it safe to use Image Compressor with confidential files?
Yes. Since processing happens entirely in your browser's memory and is never transmitted over the internet, there is no point where a confidential file could be intercepted, stored, or leaked by Nabukit — it simply never receives it.
Why is Nabukit's Zero-Server execution safer than traditional online tools?
Traditional tools require uploading your file to a remote server to process it, creating a copy outside your control. Image Compressor runs with your own browser's engine (JavaScript), so that copy never exists — no server can lose, expose, or retain your data, because it never receives it in the first place.
Which image formats does it support?
It accepts JPG, PNG and WebP as input, and can export to any of the three. It doesn't support AVIF (browsers can decode but not encode it from Canvas), animated GIF (flattens to a single frame), or SVG optimization — these are known technical limitations, not an oversight.
