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.
Good for email attachments, CMS uploads, and faster page loads without installing desktop software.
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.
Limitations
Bulk Image Compressor processes files sequentially. Dozens of images at once can exhaust mobile RAM; work in smaller batches if downloads stop midway.
Privacy & data
No. The file is read in your browser tab and the result is generated locally. Nothing is sent to Webtoolshop servers for in-browser image or PDF tools.
