How to use this guidance
- 01
Choose the intended frame
Start with the square preset or choose custom portrait dimensions appropriate for your publishing workflow.
- 02
Inspect important edges
Compare Cover / Crop and Fit & Pad so faces, writing and product details remain in the intended frame.
- 03
Check before publishing
Inspect the saved result and your publishing preview. The platform may process or display the image differently.
The square preset on this page starts at 1080 × 1080 pixels, JPG output and a 300 KB requested maximum. These are this tool's starting settings, not a guarantee about Instagram's current display behavior or upload requirements. Review your publishing interface and adjust the settings for the image you want to share.
To prepare an illustrative 4:5 portrait, use custom dimensions such as 1080 × 1350 pixels. Unlock the ratio when needed to enter the new frame, then choose Cover / Crop or Fit & Pad deliberately. The dimensions describe a shape you can create here; they do not mean every placement or preview in the platform will preserve that whole shape.
Inspect lettering, faces and objects close to the frame edges. Cover / Crop may remove them when the source and output have different proportions. Fit & Pad keeps the whole source but adds surrounding space. Stretch can distort the subject. For a set of images, compare each preview because mixed source proportions can lead to different crop decisions.
Check the saved image and the platform's publishing preview before sharing. Compression here and processing after upload are separate steps, so a local quality setting cannot promise the final appearance in the app. Keep the original and prepare a separate copy for another placement instead of repeatedly cropping and recompressing one exported file.
Common questions
Does a target guarantee an exact file size?
No. The target is a requested maximum. Inspect the actual bytes, dimensions and visual quality; a very small target can remain unmet.
Will compression keep every detail?
JPEG and WebP can lose detail. PNG uses lossless encoding, but resizing changes pixels. Keep your original and compare the preview.
Does this tool set print DPI metadata?
DPI converts centimeters or inches to pixels. This browser export does not write your chosen print-DPI tag. Check pixel dimensions and use print software for physical print settings.
