Contact sheet maker for printable photo proof sheets
This contact sheet maker turns an ordered photo set into printable, numbered proof sheets without uploading the source files. Choose A4 or Letter paper, portrait or landscape orientation, rows, columns, margins, labels, and fit behavior; preview every page, then export one multi-page PDF or high-resolution PNG or JPEG pages.
- A4 and Letter multi-page layouts
- Filenames, numbering, headers, and page numbers
- Local PDF, PNG, and JPEG export
Private proof-sheet workspace

01
How the contact sheet maker builds a printable proof set
contact sheet maker — One layout plan controls the preview, PDF, and image pages
Add individual photos or choose a folder, then place the frames in the order a reviewer should scan them. The contact sheet maker keeps selection order by default, supports drag reordering and accessible move buttons, and can apply a natural filename sort so names such as frame-2 and frame-10 remain in a useful sequence. Each card shows the original filename and intrinsic pixel dimensions before any page is generated.
contact sheet maker — A page plan is calculated from the selected paper, orientation, row count, column count, margin, and cell gap. A4 is rendered at 1,240 by 1,754 pixels and US Letter at 1,275 by 1,650 pixels, both corresponding to 150 pixels per inch for this tool. Landscape swaps the page edges. The same rectangles feed the lightweight browser preview and every full-resolution export, so the preview is not a separate mock layout.
contact sheet maker — Use Show full photo to preserve every source edge inside its cell, or Fill and crop when a uniform grid matters more than keeping the entire frame. Filenames and sequence numbers are drawn into the exported pixels, not added as removable HTML overlays. An optional header identifies the client, shoot, class, archive, or project, while page numbering makes a multi-page proof set easier to discuss.
contact sheet maker — Download PDF creates one document containing every planned page. PNG or JPEG page export produces one high-resolution file when the layout fits on one page and a ZIP of numbered pages when it spans several. The browser creates each page sequentially to control memory use, and the original photos remain unchanged on the device.
- contact sheet maker — Use filenames when reviewers need to request exact source files.
- contact sheet maker — Use numbering when short references such as 7, 12, and 18 are easier.
- contact sheet maker — Use A4 for metric print workflows and Letter for common North American printing.
- contact sheet maker — Use a multi-page PDF for one portable review document.
| Decision | Available control | Practical effect |
|---|---|---|
| contact sheet maker — Paper | A4 or US Letter | Predictable printable page proportions |
| contact sheet maker — Grid | 1–8 rows and 1–8 columns | From large proofs to dense visual indexes |
| contact sheet maker — Photo fit | Contain or cover | Preserve edges or keep cells uniform |
| contact sheet maker — Delivery | PDF, PNG, or JPEG | One document or numbered image pages |
02
contact sheet maker — Plan rows, columns, and printable page geometry
contact sheet maker — Paper proportions stay consistent across every page
The contact sheet maker converts millimetre controls to the fixed 150-pixel-per-inch page coordinate system, subtracts the header, footer, outer margins, and inter-cell gaps, then divides the remaining rectangle into equal cells. Caption height is reserved only when filenames or numbers are enabled. Every planned image records its page, cell, source file, destination rectangle, and fit mode, giving preview rendering and export rendering one inspectable source of truth.
03
contact sheet maker — Keep private photo sets on the current device
contact sheet maker — File and Canvas APIs avoid a processing upload
The contact sheet maker receives browser File objects and decodes accepted images with createImageBitmap(). Thumbnail URLs use temporary blob addresses, while page pixels are drawn with CanvasRenderingContext2D.drawImage(). The implementation has no image-upload request, remote processing endpoint, account workspace, or cloud gallery. Clearing the workspace closes decoded bitmaps and revokes temporary URLs; closing the tab also releases the session.
04
contact sheet maker — Export a multi-page PDF or numbered image pages
contact sheet maker — The saved files match the reviewed page plan
The contact sheet maker renders PDF pages as opaque JPEG image objects inside a standards-shaped PDF 1.4 document with page boxes in physical points. PNG and JPEG exports reuse the same full-resolution renderer; a browser-created ZIP stores multiple numbered pages without changing their encoded bytes. JPEG quality is explicit, PNG remains lossless for the rendered page, and every file is checked for a non-empty signature before download is enabled.
05
How this contact sheet maker is verified
contact sheet maker — Official browser references and reproducible file checks
contact sheet maker — Verification uses controlled PNG fixtures with distinct colours, sizes, and filenames. Browser checks load multiple files, sort and reorder the queue, switch page size and orientation, force a multi-page plan, inspect preview dimensions, build the PDF and image archive, reopen exported image dimensions, parse ZIP entries, and confirm PDF page objects. Network inspection separately proves that source photos are read through local blob URLs rather than sent by a request.
Contact sheet export checklist
Six practical checks before saving the proof set
- contact sheet maker confirm the photo order matches the intended review sequence.
- contact sheet maker choose A4 or Letter to match the actual printer paper.
- contact sheet maker check that filenames remain readable at the selected grid density.
- contact sheet maker compare contain and cover before accepting any edge crop.
- contact sheet maker use page numbers when the review spans more than one sheet.
- contact sheet maker open the saved PDF or image archive before sending it onward.
- contact sheet maker verify every intended frame appears in the final page count.

Frequently asked questions
Does the contact sheet maker upload my photos?
No. File selection, decoding, ordering, layout, preview, PDF construction, and image-page export run in the current browser tab.
Can the contact sheet maker create more than one page?
Yes. Page capacity equals rows multiplied by columns; extra photos continue onto numbered pages in the PDF or image-page ZIP.
contact sheet maker — Can I show both filenames and numbers?
Yes. Enable either label independently or use both so reviewers can cite a short number and still find the original source filename.
contact sheet maker — Should I choose contain or cover?
Contain keeps the full frame and may show empty space. Cover fills every image area consistently but crops source edges when aspect ratios differ.
contact sheet maker — What is the export resolution?
A4 pages are 1,240 × 1,754 pixels and Letter pages are 1,275 × 1,650 pixels before landscape rotation, using this tool’s 150 ppi layout.
