Bulk Image Compressor — free online tool
Photographers and e-commerce sellers queue dozens of product shots with the same compression settings—each file downloads when ready.
When to use Bulk Image Compressor
Process a whole product-photo folder or blog image set with the same quality settings in one sitting.
Good for email attachments, CMS uploads, and faster page loads without installing desktop software.
What Bulk Image Compressor does not do
It does not zip all outputs into one archive or apply different settings per file. Very large folders can exhaust phone RAM.
How to use Bulk Image Compressor
- Select multiple images for the Bulk Image Compressor queue.
- Apply the same quality and format settings you want across the batch.
- Start processing and approve each download prompt from the browser.
- Check your Downloads folder—each file saves separately with its original basename where possible.
Practical tips
- Use identical settings across a product batch so a storefront grid looks consistent.
- Process a few dozen files at a time on older laptops to avoid running out of memory.
- Allow multiple downloads in your browser, or files after the first may be silently blocked.
Example
Select a folder of product shots and apply the same WebP quality for a storefront.
