Format and readability
JPG often suits photos and scans; PNG works well for sharp screenshots and graphics. WebP converts before embedding. Each image becomes one document page.
Zoom in to check that text is readable. Converting a blurry photo to PDF cannot recover details or make its text selectable.
Order and page dimensions
Original size preserves each image’s proportions on its own sheet. A4 fits the image inside a standard sheet with a small margin and can simplify printing.
For A4, choose portrait, landscape or automatic orientation per image. The file list is the final sequence: cover first, then contents and appendices.
- Add supported images and wait for them to load.
- Correct photo orientation if needed and reorder the list with arrow buttons.
- Choose dimensions and orientation.
- Download and check readability, order and margins.
Transparency and memory
WebP converts with a white background. For transparent images, inspect the resulting PDF background instead of assuming all formats preserve it identically.
High-resolution photos consume memory. Reduce the batch or use smaller copies if your device slows down. Conversion is local and original images stay intact.
