What should I use to bulk resize images for a blog?

For bulk resizing blog images, the best choice depends on how many images you have and whether you want a simple GUI or an automated workflow.

Good options

• ImageMagick — best for batch processing from the command line.

  • Great if you want to resize many images at once.
  • Example:

    mogrify -resize 1200x1200\> *.jpg
    

  • The \> keeps images from being upscaled.

• Photoshop / Lightroom — good if you already use Adobe tools.

  • Easy bulk export and resizing.
  • Better for workflows involving editing, compression, and color correction.

• XnConvert — excellent free GUI tool.

  • Supports batch resizing, format conversion, renaming, and compression.
  • Good if you want a drag-and-drop app.

• IrfanView — lightweight Windows batch resizer.

  • Fast and simple for resizing lots of images.

• Squoosh CLI / TinyPNG / ImageOptim — best for web optimization.

  • These are more about compression, but often you’ll want resizing plus compression for blog performance.

What I’d recommend

• For automation: ImageMagick
• For a free GUI: XnConvert
• For best blog performance: resize first, then compress with something like TinyPNG or ImageOptim

Practical blog tip

A common target is:

• Width: 1200–1600 px for full-width blog images
• Format: WebP if supported, otherwise JPEG
• Compression: keep file sizes as low as possible without visible quality loss

If you want, I can recommend the best tool based on your OS, or give you a one-line command to resize all images in a folder.
