Frequently Asked Questions
Everything you need to know about client-side image processing.
What does "client-side processing" mean?
Client-side processing means all image compression, conversion, resizing, and editing happens directly in your web browser using JavaScript and Web APIs. No data is ever sent to a server — your images stay on your device the entire time.
Is my data really 100% private?
Absolutely. ZeroServerImg has zero servers — there is literally nowhere for your data to go. All processing uses your browser's Canvas API and Web Workers. We cannot see, access, or store your images. Your privacy is guaranteed by architecture, not policy.
Why is it completely free?
Since there are no servers, no cloud storage, and no bandwidth costs, we can offer every tool completely free forever. No premium tiers, no hidden fees, no watermarks. Just open your browser and start editing.
What image formats are supported?
We support all major formats: JPG, PNG, WebP, AVIF, GIF, BMP, and TIFF for input. Output formats include JPG, PNG, and WebP. The background remover outputs transparent PNG files.
Does it work on mobile devices?
Yes! All tools are fully responsive and work on any device with a modern browser — desktop, tablet, or mobile. No app installation needed. Just visit the website and start using the tools.
Is there a file size limit?
We recommend images up to 50MB for optimal performance. Larger files may take longer to process depending on your device. All processing happens in memory, so very large images may be limited by your browser's available RAM.
100% Free. Forever.
No premium tiers, no hidden costs. Every tool is completely free for unlimited use.
