Bulk Image Compressor

How to use this tool

1. Select multiple JPG, PNG, WebP, or GIF files. 2. Pick a compression level and output format. 3. Click Compress all. 4. Review per-file size savings in the results table. 5. Download the ZIP archive with every compressed image.

Worked example

Example: eight product JPGs totaling 18 MB compressed at medium quality might shrink to about 4 MB in one ZIP—ready to upload to a storefront or email.

When to use this

• Preparing a product catalog folder before upload.
• Shrinking an entire blog image directory for deploy.
• Uniform compression across team headshots.
• ZIP download of optimized assets for a client handoff.

Common examples

• Eight 3–5 MB product photos → one ZIP of WebP files under 500 KB each for Shopify.
• Blog image folder before static deploy → batch compress to cut total page weight.
• Team headshots for intranet → uniform compression level across 20 portraits.
