Frequently Asked Questions
Common questions we receive from creators and developers.
Are my images sent to your server when I compress them?
No. OnlineImageCompresion runs 100% locally in your browser using HTML5 Canvas and client-side encoding algorithms. There is literally no upload server attached to the tool. You can verify this by running the tool in Airplane mode or checking the browser Network inspection tab.
Can I use OnlineImageCompresion for commercial graphic design and client projects?
Yes, absolutely. The tool is 100% free for both personal and commercial use without attribution requirements, subscriptions, or royalty obligations.
Is there a file size limit or daily batch quota?
There are no artificial software limits. You can compress batches of 50+ images simultaneously. The only constraint is your computer's local RAM and browser memory capabilities.
