Why this helps
Smaller product images, clearer performance evidence
Large product photos can slow the first visit to a store, especially on mobile networks. This tool gives you a practical before-and-after comparison before you upload the files to your store.
- Batch resize images whose longest side is larger than the selected limit.
- Convert outputs to WebP with a visible quality control.
- Keep the original files unchanged and download new files separately.
FAQ
Common image optimization questions
Are my images uploaded?
No. The browser reads and converts selected files locally. This page does not send image bytes to the API or store uploads.
Which formats are supported?
PNG, JPEG, and WebP inputs are accepted. The downloadable output is WebP.
What quality should I choose?
Start around 80 to 85 for product photos, then inspect the downloaded image before publishing it.
Will the original files be replaced?
No. The tool creates new files and leaves the originals on your device unchanged.
