How to use

  1. 1. Choose images

    Tap “Choose files” and pick your photos. You can choose as many as you like. A full-screen editor opens.

  2. 2. Choose a ratio and background

    In the band below the picture, tap a ratio like “1:1” or “4:5” and a background: “White”, “Black”, “Blur”, “Gradient” or “Color”. Your image isn’t cropped; the space around it is filled in.

  3. 3. Adjust the border and position

    Move the “Border width” slider in the band to the right to add a frame-like border around the image. Drag the image with your finger to move it along the side that has space (up and down, or left and right).

  4. 4. Download

    Tap “Save” at the top right of the editor.

Great for

  • Posting wide photos to Instagram uncropped

    Making a landscape or group photo square cuts off the edges. Adding space above and below lets you post the whole photo as it is.

  • Matching shapes in a carousel

    In a multi-photo post, every image follows the ratio of the first one. Turn a mix of portrait and landscape photos into 4:5 or 1:1 all at once with the same settings.

    People who post several photos together

  • A white frame for a gallery look

    Widen the border to put a white frame around your photo. Illustrations and photos of artwork look calm and polished, like in a gallery.

    People who share illustrations or artwork

  • Stories too

    Choose 9:16 so your image isn’t cut off in Stories. A blurred background makes the extra space blend in naturally. A gradient gives it a bright, colorful look.

Good to know before you start

  • The image is shrunk to fit, so it looks smaller by the width of the space around it. If you want the photo to look bigger, cropping with “Crop images” is another option.
  • Images are saved as JPEG. Transparent areas (such as in PNGs) are filled with the background color.
  • Instagram compresses images again when you post. The quality may end up slightly lower than what you see here.

About Instagram aspect ratios

Instagram posts are basically square (1:1) or portrait (4:5 or 3:4). If you post a landscape photo or one with a different ratio as it is, the edges get cut off. This tool places your photo in the center without cropping and fills the rest with white, black, a color of your choice, a two-color gradient, or a blurred copy of the photo.

Profile grids now show posts in a tall 3:4 shape, so 4:5 posts are slightly cut off on the left and right in the grid. Choose 3:4 if you want nothing cut off in the grid, or 4:5 if you want your post to look bigger in the feed. If you’re not sure, 1:1 looks the same everywhere.

FAQ

Answers to common questions before you start.

Are my images sent anywhere?

No. Everything happens in the browser on your device, and your images are never uploaded to a server.

How do I post a wide photo to Instagram without cropping?

Choose “1:1” or “4:5” as the ratio. The photo fits the full width, with space added above and below. Post the saved image as it is, and none of the edges are cut off.

How is the “Blur” background made?

The same photo is stretched to fill the whole canvas and blurred to make the background. Because it has the same colors as the photo, the extra space stands out less than white or black. Change the strength with the “Blur strength” slider.

Can I use a gradient background?

Yes. Choose “Gradient” under “Background”, then pick a color pair from the round samples or choose the start and end colors yourself. The direction can be “Vertical”, “Horizontal” or “Diagonal”.

How do I add a white border?

Move the “Border width” slider to the right to add an even border on all four sides of the photo. You can add a border to square photos too.

Can I move the image up or down?

Yes. Drag the image to move it along the side that has space (up and down for a landscape photo, left and right for a portrait one). The position is remembered for each image.

Should I choose 4:5 or 3:4?

Choose 4:5 if you want your post to look bigger in the feed, or 3:4 if you want nothing cut off in the profile grid. Both are ratios you can post on Instagram.

Can I make many at once?

Yes. The ratio, background and border apply to every image. You can download them all together as a ZIP file. On iPhone, “Save to Photos” puts them all in the Photos app.

What size are the saved images?

By default they are 1080 px wide (the width of an Instagram post), so 1:1 gives 1080 × 1080 px. Choose “Original size” to save without shrinking the photo.

Can I use iPhone photos (HEIC)?

Yes. They are saved as JPEG, so you can post them straight to Instagram.

Is it free?

Yes, it’s free. No sign-up, no ads and no watermarks.
