Help & answers

Frequently Asked Questions

Are my images uploaded to a server?

No. Image processing (compressing, resizing, color picking) happens locally in your browser — files are never uploaded anywhere.

Does compression or resizing reduce quality?

Some quality loss is expected with lossy compression or downscaling — the tool lets you preview the result and adjust the quality/size trade-off before downloading.

What image formats are supported?

Common web formats are supported (JPG, PNG, WebP, and others depending on the specific tool) — check the tool page for the exact list.

Is there a file size limit?

Since processing happens in your browser rather than on a server, very large images are limited mainly by your device’s memory rather than a fixed cap.
