How to Bulk Compress Multiple Images at Once
Save hours with batch image compression. Compress dozens or hundreds of images simultaneously with ImageSmith's free bulk compressor.
Enable God Mode for unlimited batch processing
Click "Get God Mode" in the navbar or pricing section to unlock unlimited bulk compression. God Mode is currently free — no payment required.
Select all images at once
Drag and drop multiple images into the upload area simultaneously. You can also click to open the file picker and select multiple files with Ctrl+Click (Windows) or Cmd+Click (Mac). Upload up to 50+ images in a single batch.
Apply universal compression settings
Set a target file size (e.g., 200KB) or quality percentage. These settings apply uniformly to all images in the batch. Use "Size" mode for consistent file sizes across your entire batch, or "Quality" mode for consistent visual quality.
Select all and compress
Click "Select All" to select all uploaded images, then click "Compress Selected". ImageSmith processes all images in parallel in your browser — no server uploads, no waiting for transfers.
Download as ZIP
Once compression is complete, click "Download All" to download a ZIP file containing all compressed images. Files are named with the original filename for easy re-upload to your CMS or platform.
