Tumblr Image Post Resizer FAQ
Answers about 1280x1920 Tumblr image posts, vertical art crops, photography, edits, captions, output formats, and preview review.
This page prepares a 1280x1920 image for a vertical Tumblr image post. The tall format is useful for art, photography, edits, posters, moodboards, and visual essays that need more presence and stronger rhythm in the dashboard.
Vertical Tumblr posts work well when the subject has a clear top-to-bottom flow. Portraits, posters, tall illustrations, editorial graphics, screenshots with commentary, and layered edits can all work if the important details remain readable while scrolling.
Yes, but a horizontal source may need cropping, background extension, or a new layout to fit 1280x1920. Review the preview carefully so faces, typography, borders, or important artwork are not cut off or reduced too much.
The image itself does not need blank space for captions, because Tumblr captions appear outside the image. However, the crop should still work with surrounding text and tags, especially if the post is part of a longer commentary or reblog thread.
JPG is a good choice for photography, painterly art, textured edits, and detailed scenes. PNG is better for typography, screenshots, clean graphic layouts, comic panels, and visual essays where sharp edges and text readability matter.
Yes. Posters, moodboards, visual essays, and tall graphics can work well at 1280x1920. Keep type readable, balance the sections, and avoid making the lower part of the image feel like an afterthought or empty extension area.
Start with a clean source, avoid over-cropping the subject, and inspect fine lines or texture in the preview. If important details become too small, consider using a different crop, a square photoset image, or a closer vertical composition.
Check whether the top, middle, and bottom of the image feel balanced, whether important detail is visible, and whether the crop supports the mood of the post. If it feels awkward, adjust the framing before saving the final file.
