About this tool

Prepare product photos or website assets with one ordered set of steps. Each operation uses the previous result, so check the sequence on a representative image before running the batch.

How to use

Batch image processor

Standardise product photos. The preset fits each image proportionally on a white 1600 × 1600 canvas, then compresses it to JPEG. Small sources remain at their original size within the canvas. Add your own text or image watermark before compression if needed. Review both a landscape and a portrait photo before running the batch so products keep their proportions.

What this tool is for

Build a reorderable workflow from crop, background removal, resize, rotation, compression, conversion, watermarking, colour adjustment, and metadata removal, then run it across images, folders, or ZIP files.

How to use it

Add crop, background removal, resize, rotation, compression, conversion, watermark, colour, or metadata steps in the order they should run. Each step consumes the previous result, so verify the order and a representative preview before processing the batch.

Results and next steps

Each selected source produces one result card with preview, pixel dimensions, format, and size. Download one file, selected files, or the complete ZIP.

Privacy and local processing

Processing runs in your browser. Source images are not uploaded by this tool.

Common questions

Should resizing, watermarking or compression come first?

Usually crop and resize first, add the watermark at the final dimensions, then compress or convert. Each step uses the previous result; editing after lossy compression can introduce another generation of encoding loss.

Does the batch pipeline preserve GIF animation?

The ordinary pipeline works on a decoded canvas rather than processing every animation frame. Use the dedicated GIF editor or compressor when you need to keep animation.

How do I make square product images without cropping the product?

Set equal width and height in the resize step and choose fit with padding. Set the background and disable enlargement if needed, then add watermarks and compression. Check one landscape and one portrait source first.

What should I do when only part of a batch succeeds?

Download successful results first and read the failed files’ messages. Replace damaged sources or reduce oversized images. Select the files that need another attempt and check the processing scope before running again.
