Frequently asked questions
- Where do my images go?
- Nowhere. The file is read into your browser and re-encoded with the Canvas API. It is never uploaded, so confidential screenshots stay on your device.
- How does it make files smaller?
- It re-encodes the image as JPEG or WebP at a quality you choose. Lower quality means a smaller file, so you can trade a little fidelity for a much lighter download.
- Will I lose transparency?
- JPEG has no alpha channel, so transparent PNGs become opaque. Use WebP or keep PNG if you need transparency preserved.
- What formats can I download?
- You can export as JPEG or WebP, whichever gives you the best size for your use case.
