Prepare Photo for Instagram Post

Instagram supports three formats: square 1080×1080 (1:1), portrait 1080×1350 (4:5), and story/reel 1080×1920 (9:16). Pick a format in this tool and it will automatically resize and crop your photo to those exact dimensions.

Switch the fit mode to Fit without cropping. The whole photo is kept and scaled to fit inside the 1080 px frame, and the leftover borders are filled with white, black, or a blurred copy of the photo.

The output is still exactly 1080×1080 (or 1080×1350 / 1080×1920) — nothing is cut off.

Instagram's portrait post format is 4:5 (1080×1350 pixels). 5:7 is a print photo size, not an Instagram format — pick the Portrait option and the tool outputs the correct 4:5 pixels.

1080×1350 is 4:5 — divide both numbers by 270. It's the tallest portrait ratio Instagram shows in the feed; taller images get cropped to 4:5.

Instagram works in pixels: 1080 px on the short side. Inches and centimeters only matter for printing, where DPI comes in — at 300 DPI, 1080 px is about 9.1 cm (3.6 in). For uploading, use the pixel sizes above.

Instagram applies its own compression to all uploaded photos. By pre-compressing your photo to under 1MB with good quality settings, you reduce the amount of double-compression Instagram applies, resulting in better final image quality.

Instagram converts all uploads to JPEG regardless of original format. Using JPG from the start gives you more control over the final quality and file size.

Yes. All EXIF metadata including GPS location, camera model, and timestamp are automatically stripped from your output photo. Your processed image contains only the visual data.
