💡 Practical Conversion Tips

Choose "Fit to Image" for Mixed Dimensions

If your photos have varying orientations or odd proportions (like long till receipts), "Fit to Image" ensures zero white borders or letterboxing.

Standard A4 for Printing

For contracts and formal submissions in the UK and Europe, select A4 with standard 10mm margins for printer-friendly output.

Fast Multi-File Drag & Drop

You can drag dozens of photos into the dropzone at once; they will be parsed in parallel directly in memory.

Client-Side Vector Composition

BWTools uses client-side jsPDF vector pipelines to rasterise image matrices into compliant PDF document trees using typed binary ArrayBuffers and Blob URLs. Images are proportionally scaled using bounding box aspect ratio algorithms to preserve visual clarity without distortion or clipping.

Frequently Asked Questions

How do I reorder pages before compiling?

Each photo card has a page number indicator and "← Left" / "Right →" sequence buttons. Simply click them to shift pages earlier or later in the compilation sequence.

What does the "Full Bleed" margin setting do?

Full bleed removes all page borders (0mm), stretching the image to the very edge of the page. Selecting Standard (10mm) or Wide (20mm) adds neat, print-safe margins around your images.

Are my photos or documents uploaded to a remote server?

Never. All PDF compilation logic executes 100% in your device's browser memory via client-side JavaScript. Your images, documents, and paperwork never leave your device.
