About

In professional environments, the integrity of document exchange is non-negotiable. Sending raw raster images (JPEGs, PNGs) often results in formatting errors, printing issues, and unprofessional presentation. The JPG to PDF Converter is an architectural-grade utility designed to standardize unstructured image data into the universally accepted ISO 32000-1 (PDF) format.

Unlike consumer-grade tools that simply wrap images in a container, this engine performs local binary construction. It affords the user granular control over the trade-off between I (Information Density) and S (File Size). Users can leverage advanced features such as 1-bit thresholding for scanned documents (converting gray pixels to pure black/white), which typically reduces file size by a factor of 10. All processing occurs within the client's browser memory heap, ensuring zero data leakage.

Formulas

The PDF generation process involves calculating the optimal scaling factor (k) to fit a raster image of dimensions (wimg, himg) onto a target page (Wpage, Hpage) with a defined margin (m). The constrained optimization logic is:

Wsafe = Wpage − 2m
Hsafe = Hpage − 2m
k = minWsafewimgHsafehimg

If k > 1 and the setting upscale is FALSE, k is clamped to 1 to prevent pixelation artifacts.

Frequently Asked Questions

A standard color JPEG uses 24 bits per pixel (Red, Green, Blue). A Grayscale image uses 8 bits (256 shades of gray), effectively reducing raw data size by 66%. "Binary" mode (Thresholding) uses 1 bit per pixel (Black or White), which is ideal for text documents and receipts, often reducing a 5MB image to under 50KB while maintaining legibility.
By default, this tool maps pixels to PDF points at a 1:1 scale (72 DPI). If you select a specific paper size (e.g., A4), the engine resamples the image to fit the physical dimensions. For high-quality printing, ensure your source images are at least 2480x3508 pixels for A4.
Yes. Enable the "Metadata & Info" panel to set the document Title, Author, and Subject. This data is written into the PDF Information Dictionary (/Info object) and is visible in file properties and search indexers.
Absolutely. You can rearrange images using the drag-and-drop grid interface. The final PDF will strictly follow the visual order (Top-Left to Bottom-Right) of the grid at the moment of generation.
If enabled, the engine analyzes the aspect ratio of each image. If an image is wider than it is tall, the engine will automatically rotate the PDF page to Landscape mode for that specific page, maximizing the visible area without shrinking the content.
