Frequently Asked Questions

Common questions about converting photos to pencil sketches, charcoal drawing shaders, privacy, and batch export.

Q1.Are my uploaded photos kept private?

Yes, all Gaussian blur, color inversion, and color-dodge blending filters execute locally in your browser memory. No images are ever uploaded.

Q2.Can I convert multiple photos to sketches at once?

Yes, you can upload multiple photos simultaneously, apply your chosen sketch style across all of them, and export everything in a single ZIP file.

Q3.What sketch styles are available?

You can choose between delicate Graphite Pencil, rich high-contrast Charcoal, and bold graphic Ink Outline styles with custom intensity sliders.

Q4.Which input formats can I turn into a pencil sketch?

You can convert JPG, PNG, and WebP photos into graphite-style pencil drawings. Portraits, landscapes, and pet photos all work well — the luminance engine reads every pixel locally in browser memory and renders the monochrome sketch at full original resolution.

Q5.How does the sketch intensity slider work?

Adjusting the intensity slider controls the blur radius and blend threshold. Lower values yield sharp, fine outlines, while higher values create deeper tonal shading and cross-hatching.
