Common questions
What to know before the first upload.
Will a PNG conversion be pixel-perfect?
Pixel-perfect is not the promise. The goal is a strong editable production starting point that preserves structure, content, and assets.
Can image crops be adjusted?
Yes. The editor includes crop refinement so your team can correct imperfect image extraction before export.
Are uploaded images public?
No. Source, preview, and extracted assets stay private. Export bundles local assets into the downloaded ZIP.
