Image to PDF converter for one private, ordered document

01

How the image to PDF converter builds one document

image to PDF converter — One image becomes one reviewed PDF page

image to PDF converter — Add up to 30 files, then drag cards or use the accessible move buttons until the queue matches the document’s reading order. Each card reports the original pixel dimensions, and its left and right rotation controls change only the working copy used for the PDF.

image to PDF converter — Fit page to image keeps each page proportional to its rotated source. A4 and US Letter create consistent paper pages; Automatic orientation chooses portrait or landscape for each image, while the manual choices keep every page in the same direction.

image to PDF converter — Show complete image preserves every edge inside the chosen margin. Fill page and crop uses the page area completely and may remove outer edges, so the preview should be checked before downloading the PDF.

The image to PDF converter renders pages sequentially and embeds them in one PDF 1.4 file. The selected originals are not overwritten, and no account or remote image-processing endpoint is required for the conversion flow.

• image to PDF converter — Arrange pages before choosing the final paper settings.
• image to PDF converter — Rotate phone photos that contain an incorrect display direction.
• image to PDF converter — Use complete-image fitting when no edge may be lost.
• image to PDF converter — Open the downloaded PDF and confirm order and page count.

image to PDF converter — Plan image order and page geometry

image to PDF converter — The queue defines the final document sequence

The image to PDF converter calculates a page for every rotated image. Source-sized pages use 150 pixels per inch for the PDF coordinate conversion; fixed pages use 595.28 × 841.89 points for A4 or 612 × 792 points for US Letter before landscape rotation.

03

image to PDF converter — Keep source images on the device

image to PDF converter — Browser file and canvas APIs handle the working copies

The image to PDF converter receives browser File objects, decodes supported formats with createImageBitmap(), and draws only local working copies. Clearing the queue closes bitmaps and revokes temporary blob URLs.

04

image to PDF converter — Create a valid multi-page PDF

image to PDF converter — Sequential rendering controls memory and page order

The image to PDF converter writes JPEG page streams, individual MediaBox values, a Pages tree, cross-reference offsets, and an end-of-file marker into a PDF 1.4 Blob. Each page is created and released before the next one to reduce peak canvas memory.

05

Verify the image to PDF converter

image to PDF converter — Official browser references and reproducible file checks

image to PDF converter — Verification uses controlled red, blue, transparent, wide, portrait, and landscape PNG fixtures. Checks cover queue order, rotation, source/A4/Letter sizing, preview canvases, PDF header and trailer signatures, page-object count, downloaded bytes, console errors, and unexpected network requests.

image to PDF converter — How the contact sheet maker builds a printable proof set

image to PDF converter — One layout plan controls the preview, PDF, and image pages

image to PDF converter — 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.

image to PDF converter — 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.

image to PDF converter — 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.
