Recommended size

For a portrait feed post, use 1080 x 1350 pixels. This gives more vertical space in the feed while keeping the image within Instagram's common 4:5 display ratio.

A portrait post usually performs better when the subject is framed vertically rather than simply squeezed into a square. If the original photo is wide, crop carefully instead of stretching it. Keep faces, product details, or important text away from the edge so they are not lost when Instagram previews the post in different contexts.

The Image Resizer lets you add a JPG, PNG, or WebP image, choose a social preset, adjust the crop, and export a practical web image. For most photos, JPG or WebP will be smaller than PNG. For graphics with transparency, PNG may still be the better choice.

Why browser-only matters

Social images may be unpublished designs, client work, or personal photos. PDFTechnician resizes them on your device instead of uploading them to a server.

This is especially helpful when you are preparing brand assets, product launches, client previews, or images that contain location data. The browser-based workflow keeps the original file local and exports a clean copy for posting.
