It solves the problem of one image going to several platforms, each with a different ratio; if all you need is a proportional scale to a given width, “Resize Images” is more direct.
<preset>-WxH.jpg and can be packaged as a zip.| Input | Output | Notes |
|---|---|---|
| A 4000×3000 landscape image, vertical short video ticked, centre crop, focus 50/50 | 1080×1920, keeping only the middle vertical band |
The crop window is centred |
| The same image with the horizontal focus pulled to 20% | The crop window moves left and keeps the subject on the left |
The focus only applies to centre crop |
| A 1080×1920 portrait image, article header ticked, fit with padding, white | 900×383 with the image scaled to a height of 383, centred, leaving wide white bands |
The whole picture is kept |
A social media manager exports one poster as an article header, a portrait cover and a microblog cover without cropping each by hand.
For a photo with the person on the right, pull the horizontal focus to 80% so the vertical short-video crop does not cut them off.
Use fit with padding and a brand-colour background to keep the whole landscape picture.
Produce an 800×800 main image and a 500×500 thumbnail from one product shot.
The presets use commonly recommended values and platforms adjust their specifications; check the platform's current size guidance before uploading.
JPG has no alpha channel, so transparent areas of a transparent PNG are filled with the “padding background colour”; choose PNG when you need transparency.
No — one image and several sizes here. To bring many images to one size, use “Resize Images”.
All sizes are rendered locally in the browser and images are never uploaded to any server; they are released from memory when the page is closed.

Export one image to every platform size (Instagram, YouTube, X, Facebook, WeChat, Xiaohongshu, Douyin, Bilibili…) with crop or padding, zipped
The preview appears once you add an image
"Centre crop" uses the focus sliders to decide where the subject stays; "Fit with padding" keeps the whole picture and pads with the background colour. With JPG, transparent areas are filled with the background colour.
