What is Smart Resize?

Smart Resize is an AI assistant that adapts images and videos to any platform dimension while keeping the important parts in frame. Also called intelligent cropping or smart crop, it analyzes your content to understand what matters most — faces, products, text — then automatically positions those elements perfectly for each format. Think of it like having a professional editor who knows exactly how to frame your shot for Instagram Stories, LinkedIn posts, or YouTube thumbnails.

Common use cases

  • Social media: Convert one photo into Instagram post (1:1), Story (9:16), and Reel (9:16) formats
  • E-commerce: Adapt product photos for Amazon (1:1), Etsy (4:5), and your website banner (16:9)
  • Marketing: Resize campaign visuals for Facebook ads (1.91:1), Google Display (1.91:1), and Pinterest pins (2:3)
  • Video content: Convert horizontal YouTube videos (16:9) to vertical TikTok format (9:16)
  • Presentations: Adjust images for slides (16:9) and print materials (various sizes)
  • Portfolio work: Create multiple format versions without manual cropping

Resize your images step by step

STEP 1: Upload your image

  • On web: Go to green-salad-4efd.toolsminati.workers.dev/ai-agent/?agentId=smart-resize → Upload your image or video
  • On mobile: Open Picsart → Chat with Smart Resize agent → Attach your media file
Open Smart Resize

STEP 2: Choose your target dimensions

Tell Smart Resize what platforms or sizes you need:

  • Platform presets: Instagram Post, Story, Reel, TikTok, YouTube, LinkedIn, Facebook, Pinterest
  • Standard ratios: 16:9, 9:16, 1:1, 4:5, 2:3, 3:4
  • Custom dimensions: Specify exact pixel width and height
  • Batch mode: Select multiple formats to generate all at once

STEP 3: Review AI positioning

Smart Resize analyzes your image and positions the crop intelligently. Preview each format to see how the AI framed your content. If needed, manually adjust the crop area by dragging the frame or tapping to reposition the focus point.

STEP 4: Download your resized images

Check that each format looks right: Not happy with a crop? Regenerate with a different focus point, or manually fine-tune the position before downloading.

  • Important elements (faces, text, products) are fully visible
  • No awkward cuts through key objects
  • Composition feels balanced for each aspect ratio

Tips for best results

💡 Start with high-resolution images

Use images at least 1080px on the shortest side. Higher resolution gives the AI more detail to work with when cropping down to smaller formats.

💡 Place key elements in the center third

If you know you'll need multiple formats, compose your original shot with important elements in the middle area. This gives Smart Resize more flexibility to crop while keeping everything in frame.

💡 Use batch mode for social campaigns

If you're posting the same content across platforms, select all needed formats at once. Smart Resize will generate them all in one go, saving you time switching between tools.

💡 Check mobile preview for vertical formats

Stories and Reels are viewed on phones. After generating, check that text is readable and faces aren't too small when viewed at actual mobile size.

Frequently asked questions

Yes, Smart Resize works with both images and videos. Upload your video and the AI will intelligently crop it to your target dimensions while tracking movement to keep key elements in frame. This is especially useful for converting horizontal YouTube videos to vertical TikTok or Instagram Reels format. The process is the same as resizing images — select your formats and let the AI handle the positioning.

Smart Resize uses AI to analyze your image and identify important elements — faces, text, products, or areas with high detail. It then positions the crop to keep these elements centered and fully visible. The AI considers composition rules like the rule of thirds and avoids cutting through objects awkwardly. You can override the AI's choice by manually adjusting the crop position if needed.

Smart Resize is free to start. You can resize images and generate multiple formats without a paid plan. [CHECK PRODUCT: pricing detail for limits on number of resizes or batch processing on free tier]. If you're processing large volumes or need priority generation, Picsart's paid plans offer higher limits and faster processing.

Yes, you can batch process multiple images. Upload several files and select your target dimensions — Smart Resize will apply the same settings to all images and generate the results together. This is a huge time-saver if you're preparing a social media campaign or e-commerce product lineup. Each image gets individually analyzed, so the AI will position crops differently based on each photo's content.
