Which platforms are supported?

Instagram (square, portrait, story, reel), YouTube (thumbnail, channel art), X/Twitter (post, header), Facebook (post, cover), LinkedIn (post, banner), and more.

Will my image be cropped?

If the aspect ratio differs, center-crop is applied by default. Enable the 'pad with background' option to preserve the original ratio with added margins.

Can I export for multiple platforms at once?

Yes. Select multiple presets and download each individually or as a single ZIP archive.

What file format is recommended?

Most platforms recommend JPG or PNG. Use PNG when transparency is required.

What if a platform changes its recommended sizes?

Presets are updated when major platform changes are announced. Check the platform's official help center for the very latest specs.

Social Media Resizing Tips

Instagram — Optimal Sizes by Format

Use 1080×1080 for square posts, 1080×1350 for portrait (4:5 ratio gets more feed real estate), and 1080×1920 for Stories and Reels. The 4:5 portrait ratio is currently favored by the Instagram algorithm for feed reach.

YouTube — Thumbnails & Channel Art

Upload thumbnails at 1280×720 (16:9). For channel art, use 2560×1440 — different areas are shown on TV, desktop, and mobile. Keep key text and logos within the 1546×423 safe zone in the center.

X (Twitter) — Prevent Image Cropping

Timeline images are cropped to a 2:1 ratio. Use 1600×900 and place important content in the center to avoid cropping. When posting 4 images, each is displayed at a different ratio, so check previews carefully.
