How to Use the Bulk Image Compressor

1. Upload mixed images

Product shots, lifestyle, thumbnails — any browser-decodable images in one batch.

2. Set quality and format

Quality 10–100 (default 80); output JPEG (smaller) or PNG (lossless). No resize option — full dimensions are kept.

3. Download ZIP

Extensions normalize to .jpg/.png. One batch save counts as one Pro download.

Frequently Asked Questions

What quality setting keeps photos sharp?

Quality 80 for product and lifestyle shots, lower for thumbnails, PNG for graphics with text. Outputs are JPEG or PNG only — for WebP, run the ZIP through the Bulk Image Converter afterwards.

Compress or resize first?

This tool cannot resize — it keeps full dimensions and only re-encodes. To cut pixels first, run the batch through the Bulk Image Resizer (e.g. 1600px), then compress the smaller files here.

WebP or JPEG output for my store?

No WebP output exists here — JPEG for site images and marketplaces alike, PNG for graphics with text. For WebP delivery, convert afterwards in the Bulk Image Converter.

Are my product photos uploaded?

No — compression runs locally in your browser; images never leave your device. The compressed set saves as one Pro download (signed-in free: 2 a day, so batch deliberately; Pro unlimited).
