Resizing photos individually is tedious, especially when preparing hundreds of images for the web, print, or client delivery. Bulk resize in Lightroom streamlines this process, ensuring consistency and saving hours of manual work. Whether you’re optimizing images for Instagram, a portfolio site, or a print lab, this guide will show you how to resize multiple photos at once—and do it right.
Why Bulk Resize in Lightroom?
Bulk resize in Lightroom is essential for:
- Web Optimization: Meet platform requirements (e.g., Instagram’s 1080px width) and reduce load times.
- Print Preparation: Resize images to specific dimensions for framed prints, albums, or posters.
- Storage Management: Reduce file sizes to free up disk space without losing critical quality.
Combined with batch photo editing, bulk resizing ensures your images are polished and ready for their final use.
How to Bulk Resize in Lightroom
Step 1: Select Your Photos
- In the Library Module, select multiple photos using Shift + Click (for a range) or Ctrl/Cmd + Click (for individual images).

2. Use Export Presets for Consistency
Save your resizing settings as a preset:
- Configure your ideal resizing settings.
- Click Add in the Export dialog’s preset panel and name your preset (e.g., “Web-1920px”).
- Reuse it for future batches with one click.

FAQs About Bulk Resizing in Lightroom
1. Does resizing reduce image quality?
Resizing can cause quality loss if done excessively. Use high-quality settings (e.g., 90% JPEG quality) and avoid upscaling beyond the original resolution.
2. Can I resize photos without exporting them?
No. Lightroom requires exporting to resize images, as edits in the catalog are non-destructive.
3. What’s the best format for resizing?
- JPEG: Ideal for web (small file size).
- TIFF/PNG: Best for print (lossless quality).
4. How do I resize photos for Instagram?
Use Width & Height set to 1080px width (Instagram’s recommended size) and export as JPEG at 72 PPI.
5. Why are my resized images blurry?
- You may have upscaled beyond the original resolution.
- Use the Sharpen For option in the Export dialog (e.g., “Screen” for web).
6. Can I automate bulk resizing?
Yes! Use Export Presets to save and reuse resizing configurations.
7. How do I resize photos for a print lab?
Set 300 PPI and use Long Edge sizing (e.g., 3000px for a 10-inch print). Confirm requirements with your lab.
8. Can I bulk resize on Lightroom Mobile?
No, but you can sync photos to the desktop version, resize them, and re-sync.
9. How do I batch resize with custom aspect ratios?
Use the Dimensions resizing option and input the exact width/height (e.g., 4:5 for portrait Instagram posts).
10. Does Lightroom Classic handle bulk resizing better than Lightroom CC?
Both versions support bulk resizing, but Lightroom Classic offers more advanced export customization.
