About
Ever had a photo rejected because it was 2 KB over the limit, or cropped someone's head off to fit Instagram? Six-IR fixes both.
Pick a platform (Instagram, TikTok, YouTube, Facebook, LinkedIn, X, Pinterest, Etsy, print and more) and it crops to the exact pixel size, with smart crop keeping faces in frame. Set a maximum file size in KB and it saves the best quality that fits. It opens iPhone HEIC photos, batches 10 photos into one zip, and removes backgrounds on your own device.
Free, no sign-up, no watermark, and your photos are never uploaded: everything runs in your browser.
Works inside Claude and ChatGPT: add the Six-IR connector (six-ir.com/mcp) and ask "what size is a YouTube thumbnail?" to get the answer and a link that opens the resizer ready to go.
Six-IR apps for iPhone, iPad and Android are coming soon.
