Frequently asked questions
Is my image uploaded anywhere?
No. The check runs entirely in your browser with the file you picked — nothing is sent to any server, and closing the page removes it from memory.
Why do platforms crop images?
Each feed enforces its own aspect ratios and center-crops anything that doesn't match — that's how faces and text get cut off. Exporting at the platform's recommended ratio is the only reliable fix.
Which sizes should I export?
Use the size shown on each card, or open the full guides: 1080×1350 for Instagram portrait, 1200×630 for Facebook links, 1600×900 for X, 1200×627 for LinkedIn, 1080×1920 for TikTok and 1280×720 for YouTube thumbnails.
