How to use it
- 1Pick your photoAny photo from your phone. Nothing is uploaded — the work happens on your device.
- 2Pick a formatPortrait (1080×1350) takes up the most room in the feed. Story is 1080×1920. Square still works everywhere.
- 3DownloadYou get a full-resolution JPEG ready to post. Blurred background fills the frame so nothing is cropped away.
Instagram image sizes in 2026
Instagram accepts three shapes. Anything else gets cropped to one of them, and the crop is what eats the edge of your product.
| Where | Size | Ratio | Note |
|---|---|---|---|
| SquareFeed post | 1080 × 1080 | 1:1 | Safe everywhere, but takes the least screen |
| PortraitFeed post | 1080 × 1350 | 4:5 | Best choice — fills the most screen while scrolling |
| Story / ReelsStory and Reels | 1080 × 1920 | 9:16 | Keep text away from the top and bottom 15% |
Who this is for
Jewellers
A ring photographed on the counter is almost never 4:5. Cropping cuts the band; the blurred background keeps the whole piece.
Bakeries and cafés
Cake photos come out wide. Portrait format with a soft background reads as a proper post rather than a snapshot.
Boutiques
Turn one product photo into a square for the feed and a 9:16 for the story without opening an editor.
Want it moving?
The same photo can become a short product video — the product is placed in a scene and never redrawn. That's what Reelvitrin does.

Is my photo uploaded to a server?
No. The whole tool runs in your browser using the canvas your device already has. There is no request to us, which is also why it works with a bad connection.
Do I need an account?
No account, no email, no limit. Use it as often as you like.
Why a blurred background instead of cropping?
Instagram crops to its own ratio and that usually cuts the edge off a product. Filling the rest of the frame with a blurred copy of the same photo keeps the whole product visible.
Which size should I use?
Portrait, 1080×1350. It fills more of the screen as someone scrolls than a square does. Use 1080×1920 for stories and reels.
Does it lose quality?
No. The canvas is built at the real output size — 1080 pixels wide — and exported as a high quality JPEG. It is not a screen-sized preview scaled up.
Does it work on a phone?
Yes, and that is the main case. The page is built for a phone browser; the preview sits above the controls so you can see the change as you make it.
