About this tool
A vertical story and a wide cover often need different framing. Select the output presets, inspect each version and use the guides to leave room around essential text and faces.
How to use
Social media image resizer
Create three layouts from one source. The preset selects 1080 × 1080, 1080 × 1350 and 1080 × 1920. Fit preserves the whole picture with padding; crop-to-fill removes edges. Switch between target previews to check the subject, text and safe area. Enlarging a small image does not add real detail, and the guides do not replace the platform’s current publishing requirements.
What this tool is for
Create Instagram, Stories, Open Graph, X, and YouTube sizes in one pass, with safe-area guides that help keep important content clear of interface overlays.
How to use it
Select the platform presets you need, choose crop, fit, or padding, and use the safe-area overlay to keep faces and text clear of interface chrome. One run can create several social-media variants from each source.
Results and next steps
A source may produce several tiles, frames, sizes, or formats. Output names include the relevant identifier, and the chosen set can be downloaded individually or as a ZIP.

Common questions
Will a platform always display the full exported image?
No. The selected preset defines output pixels, and the safe-area guide is a framing aid. Different placements may crop again or add interface overlays. Review each version and keep essential text and subjects away from vulnerable edges.
How can I reuse a landscape photo for both posts and vertical stories?
Fit keeps the whole picture with background padding. Crop to fill removes edges, while stretch may distort people. Preview each size; prepare a better crop separately when one composition cannot serve every placement.
Which size does the preview show when several are selected?
The preview follows the currently selected preset, while all checked sizes remain in the export. Review square, portrait and landscape versions in turn. Use dimensions in result names to distinguish them rather than checking only the first.
