No. Every tool in this workflow runs entirely in your browser using canvas and JavaScript. You can load a tool page, disconnect from the internet, and keep working — that is the simplest way to verify the claim.

No. Photos from a camera or phone benefit most from metadata removal; screenshots usually need redaction instead (they rarely carry GPS data). Watermarking matters when you publish your own work. Compression and resizing are about the destination, not privacy — use them when the platform needs it.

Redact first or clean metadata first — either works. Just make watermarking and compression the last steps: compressing before redacting means re-encoding twice, and watermarking before resizing can make the watermark too small or too large in the final output.

For these tasks, yes. Modern browser APIs decode and encode images with the same codecs desktop apps use. The practical limits are very large files (hundreds of megapixels) and specialized needs like RAW development — for everyday sharing preparation, the browser is more than enough.
