FAQ
Can I reorder pages before generating?
Yes. After dropping your images, drag the thumbnails to rearrange the page order before clicking Generate PDF.
What page sizes are supported?
A4, Letter (US standard), and Fit to Image — where the PDF page dimensions match each image exactly.
Is there a page limit?
No hard limit. Large numbers of high-resolution images may be slow depending on your device memory.
Does the PDF contain original quality images?
Images are converted to JPEG at 92% quality before embedding. For lossless output, use PNG source images with Fit to Image.
Can I set portrait or landscape orientation?
Yes. Choose portrait or landscape in the toolbar before generating. Fit to Image always matches the source orientation.
Are my images uploaded anywhere?
No. The PDF is built entirely in your browser using a pure JavaScript PDF writer. Nothing is uploaded.
