Questions

Frequently Asked Questions

In-browser jsPDF engine, interactive drag-and-drop sequencing, and custom page geometry.

1

Which image formats can I combine into a single PDF document?

You can combine JPG, PNG, WebP, GIF, BMP, and TIFF graphics into a standardized ISO 32000-1 PDF document with zero quality loss.
2

Can I reorder pages before generating the final PDF?

Yes. Our visual workspace provides an interactive drag-and-drop sequencing interface where you can effortlessly arrange thumbnail cards in any order.
3

What page sizing and margin options are supported?

You can select 'Fit Image' for borderless full-bleed viewing, or choose standard physical page geometries including ISO A4 and US Letter with custom margins.
4

Are my confidential contracts or personal photos uploaded to an external server?

No. The entire decoding, EXIF orientation handling, and jsPDF assembly process runs 100% locally in your browser memory. Your documents never touch a server.
5

Does converting images to PDF reduce their visual print quality?

No. The converter embeds raw raster image bitstreams directly into PDF XObject dictionaries, preserving full 300+ DPI source resolution for crisp physical printing.
6

Is there any limit on the number of images I can combine into a PDF?

No artificial limits. You can combine dozens or hundreds of high-resolution photos and document scans without subscription paywalls, size caps, or watermarks.
