Frequently asked questions
Why 1080x1080 instead of 1024x1024?+
1080px is the display resolution of most modern screens, so the image renders perfectly sharp on any device without platform upscaling.
Does it work on mobile?+
Yes — the resizer runs in any browser, including your phone, and never uploads your image.
