A short note on a stack of photos

The image job that comes back most often is one choice applied to many files: one quality, one format, one crop, one watermark. PicZero keeps the files you added as a list in the current tab, so you do not repeat that choice on every image.

Look at the first one

Process the first image in the list before the rest. The compress page shows the size before and after. If the edges go soft, or the file is still over a form's limit, change the quality or the target kilobytes there, and only then apply it to the whole list. Do not put a portrait crop on a wide photo and hope. The full steps are in a folder of photos.

Where to start on quality, what the target-size range is, and the rule that a same-format result which is not smaller returns the original bytes, are in compress without uploading. If the receiver also requires JPG, PNG, WebP, or AVIF, continue with format conversion.

Settings can be shared. Strokes cannot

Quality, format, target size, crop, watermark, and rename rules apply to every image. Strokes you paint do not. Cutout keep and erase stay on the current photo. See cut out locally. Lock the preset on one representative image before a batch, and repair by hand only where it is needed.

The download is a new file

The originals stay in the folder. Save one new file, or a zip of many. PicZero does not write back to the path you dragged in. Close the tab before you download and the results in the list are gone. The originals on disk are still there.
