Start with a clear selection
Gather one coherent batch before loading the files. For example, compare a single product angle across several shots or keep a short portrait session together. Exclude unrelated pictures that make the sheet harder to scan. The contact sheet tool accepts up to 24 JPG, PNG or WebP images, with a limit of 20 MB and 30 megapixels for each source.
Give important differences enough space
Use fewer columns when fine detail matters. Increase the column count when your goal is to see the overall sequence. Check the preview after each change, including the page margins. Tiny thumbnails may save paper but can hide the feature you are comparing. If the batch feels crowded, split it into two smaller contact sheets and compare them side by side.
Apply the chosen order and columns in the contact sheet maker and preview every page.
Review the exported PDF
Confirm that all intended images appear and that the displayed order makes sense. Print a test page if paper review is part of your workflow. Contact sheet output uses resized, compressed images to make a practical PDF. Keep the originals separately and return to them for detailed editing or final prints. A contact sheet records a selection; it should not become your only copy of the source images.
