Instagram tools that run in your browser
Cut a picture into a profile grid, split a panorama into carousel slides, and get posts out at the size the feed actually wants. Each tool does one job, needs no account, and works on the file already on your device.

Instagram sizes, in one place
Instagram serves 1080 px on the long side and downsamples anything bigger, so matching the shape matters and chasing the pixels does not.
| Where | Size | Worth knowing |
|---|---|---|
| Feed post (portrait) | 1080 × 1350 | 4:5 — the tallest a feed post can be, and the most screen it can take |
| Feed post (square) | 1080 × 1080 | 1:1 — the classic shape, still safe everywhere |
| Feed post (landscape) | 1080 × 566 | 1.91:1 — the widest before the sides get cropped |
| Reels and Stories | 1080 × 1920 | 9:16 — keep captions clear of the top and bottom 15% |
| Profile grid tile | 1080 × 1350 | Tiles have been 4:5 since the 2025 redesign; older grids were square |
| Carousel | up to 20 slides | Every slide takes the shape of the first one |
Why work this way
Most free Instagram sites want an upload, an email address, or a login to your account. These want a file that is already on your phone.
Nothing is uploaded
Your photos and clips are processed in the browser, on your own device. No account is connected to Instagram and no file is sent to a server.
No watermark
Exports come out clean. Nothing is stamped on the picture and no feature is held back for a paid tier.
The shape the feed wants
Post something the wrong shape and Instagram crops it for you — usually through a face. Every tool here lets you make that decision instead.
Made for a phone too
These run on the device you post from, not just a laptop. Very large images still go more smoothly on a desktop.
