FAQ
Do I need an account or upload my image anywhere?
No. Everything runs locally in your browser using the HTML canvas — your image never leaves your device, and nothing is stored or uploaded to a server.
Why does the exported file size differ from the original?
Re-encoding changes compression. Facebook enforces a hard limit of ≤ 8 MB; if an export exceeds it, try JPG or lower-detail source art.
Can I batch several images at once?
Yes — drop or select multiple files and every 3-pixel variant is generated per file. Download each output with one click.
