How to make a photo contact sheet on a Mac
By Himanshu Ranjan · Updated 8 November 2026
A contact sheet puts many photo thumbnails with their file names on one page, so you can review a shoot at a glance. In FileDial, select the photos and run Share › Contact sheet…, which writes one PDF or JPG. For one full page per photo, use Combine › Images to PDF instead.
What a contact sheet is for
The name comes from the film era. Wikipedia describes contact prints as used to produce proof sheets from entire rolls, so a photographer could choose which negatives to enlarge and catalogue their images. Digital contact sheets do the same job: one page showing every frame, small, with an identifier under each.
Typical uses today are sending a client a quick overview of a shoot so they can name favourites by file name, printing a reference page for a folder, or archiving a visual index next to a project. A sheet is for choosing, not for viewing detail.
Contact sheet or images to PDF?
These are two different outputs and people confuse them. A contact sheet shows many photos small on a page. Images to PDF makes a document with one page per image. FileDial has both, so the question is what the reader needs to do.
- Share › Contact sheet…: thumbnails with file names, one PDF or JPG. Best for choosing.
- Combine › Images to PDF: one page per image, sized to the image. Best for reading full pictures.
- Combine › Images to PDF (A4) or (Letter): one A4 or Letter page per image, for printing.
- Share › Portfolio PDF…: cover, one photo per page with its name and page numbers. Best for presenting work.
Steps in FileDial
Selection order and file names matter, because the names appear under each thumbnail. If your files have camera names like IMG_4021, rename them first with Rename › Rename with sequence… or Rename › Rename by date taken so the sheet is easier to read.
- Select the photos in Finder, or a whole folder.
- Hold the right Option key to open the dial, or right-click and choose Open in FileDial.
- Choose Share, then release on Share › Contact sheet…
- Pick the options it offers, choose PDF or JPG, and run it.
- Open the new sheet. The photos are not changed.
Doing it with built-in Mac tools
Preview can print a multi-image selection with several images per page through the Print dialog, and Photos has its own print layouts, including contact sheet style options on some versions. Steps and layout names vary by macOS version, so look in File > Print in Preview and the Layout pop-up rather than relying on exact menu wording.
The built-in route gives you less control over captions. File names under each thumbnail, the part clients actually use when replying, are the reason to prefer a dedicated tool.
Getting a useful sheet
The best contact sheets are made from a curated set. If you feed in 600 near-identical frames, you get a page of tiny near-identical thumbnails and nobody can choose from it. Cull first. FileDial's Combine › Find similar and blurry photos writes a CSV report and copies suggested rejects to a folder, and nothing is deleted, so you can clear obvious rejects before building a sheet.
Think about the reader as well. A client reviewing a wedding wants dozens of frames per page so the sheet stays short, while a designer reviewing a product set might want fewer, larger thumbnails. Split large shoots into several sheets by folder, such as ceremony and reception, rather than one overwhelming page.
Finally, name the sheet clearly and keep it with the project. A PDF sheet saved beside the folder works as a visual table of contents for the whole shoot, and it is far easier to find things in a year than to open every file.
- Cull duplicates before building the sheet.
- Split big shoots into several sheets.
- Save the sheet next to the project.
Mistakes to avoid
Do not send a contact sheet when the reader needs detail. Thumbnails hide focus problems, closed eyes and fine flaws, so choose from the sheet and then check the full-size file. Another mistake is leaving camera names like IMG_4021 in place; if the reader replies with picks, you want names that make sense.
If you only need to see a folder yourself, Finder's Gallery view or Quick Look is faster. FileDial earns its place when you must send, print or archive the overview. Also check that a contact sheet is not the wrong format: for a presentation, a Portfolio PDF with one photo per page reads better, and for a handout, a Print sheet puts copies on a page.
Sharing safely
A contact sheet is a good thing to email because it is one small file, but remember the thumbnails are still your photos. FileDial builds sheets locally and never uploads them. If the sheet leaves your hands as a JPG, thumbnails from a larger file will not contain the original's location metadata, but you should still check any full-size files you send alongside it.
Questions
What is a contact sheet in digital photography?
It is a single page of small thumbnails, one per photo, usually with file names. The idea comes from film proof sheets, which let photographers pick which frames to enlarge. Digitally it is used to review shoots, collect client picks and document folders.
Can the contact sheet be a PDF?
Yes. FileDial's Share › Contact sheet… writes thumbnails with file names as one PDF or JPG. A PDF is the better choice for email and printing, while a JPG is handy for dropping into a chat or a slide. A PDF stays sharp when zoomed or printed, while a JPG sheet is one raster picture that blurs if enlarged.
How is this different from images to PDF?
Images to PDF makes one page per image, sized for reading each photo in full. A contact sheet squeezes many photos onto one page for choosing. Use Combine › Images to PDF for documents and Share › Contact sheet… for overviews.
Will the file names show under each photo?
Yes, FileDial describes Contact sheet as thumbnails with file names. Because of that it helps to rename messy camera names first, for example with Rename › Rename by date taken, so the labels on the sheet make sense to the reader.
