Frequently Asked Questions
Is it safe to upload my private photos?
Yes. ToolXero uses JavaScript to process images directly in your browser. Your images are never uploaded to any server. You can even use this tool while offline.
What's the best quality setting?
For web use, 80% is usually the "sweet spot" where file size drops significantly while visual quality remains indistinguishable from the original.
Can I convert to a different format while compressing?
