❓ Questions

Frequently Asked

Everything you need to know about Image Toolkit.

Yes — free forever with no account required, no watermarks on output, and no hidden feature limits. All tools including AI background removal are available without paying anything.
Never. All processing happens inside your browser using the Canvas API and, for background removal, an ONNX model running locally. Your files never leave your device — there's no backend at all.
You can upload JPEG, PNG, WebP, GIF, and SVG files up to 50MB. You can export your edited image as JPEG, PNG, or WebP. For background removal, the output is always a transparent PNG.
It uses the @imgly/background-removal library, which runs an AI segmentation model (ONNX format) entirely in your browser. The first time you use it, it downloads ~40MB — after that, it runs instantly on any image.
Yes. Every edit (resize, crop, adjust, rotate, etc.) is saved to a full history stack. Press Ctrl+Z to undo and Ctrl+Y to redo. You can step back through unlimited edits without losing your work.
Resizing always involves resampling, but the browser Canvas API produces clean results. For compression, use 80–90% quality for JPEG — this typically reduces file size by 40–60% with no visible quality loss.
