- Photo File Size Reducer on a Mac, with three sample photos or photos you want to reduce.
- A file-size requirement of 900 KB for each JPEG in your batch.
Need to upload several photos under a 900 KB size limit? Photo File Size Reducer lets you set one JPEG target for the batch, measure each planned output, and inspect the results before saving any files.
1.Load a sample photo batch
Add the bundled sample photos to your workset. The left sidebar lists three sources, and the selected photo appears in the main view. You can use your own images for the same workflow.

Click Measure and let the app calculate each output. The sample photos measure about 882 KB, 892 KB and 888 KB. In Inspect, compare Source and Delivery with Fit or Actual Pixels before choosing Review Delivery.

After the last step
Actual sizes depend on each image and the selected requirements.
Tips
Try the included sample images first, then repeat these steps with your own photo batch.
After measuring, check each output's actual size rather than assuming every image can meet the target.
Use Fit for the whole image and Actual Pixels to inspect details before you approve the delivery.
Watch outA size target cannot guarantee that every image will fit under the limit with the selected requirements. Check any file the app marks as unable to meet them.
Watch outThe measurement step plans and previews the output; no files have been saved by this walkthrough. Review file names and the destination before delivery.
