Image to PDF

How to use it

1. Choose one or more PNG or JPEG images (up to 50 files, 10MB each).
2. Reorder pages with the up and down arrows, or drop one with the cross.
3. Pick a page size: the image's own pixel size (1px = 1pt), A4 or Letter.
4. Choose an orientation (auto follows each image's shape) and set a margin in millimeters.
5. Click Build PDF, then Download. Every image is scaled to fit its page and centered.

Common use cases

• Scans into one document — stitch photographed pages into a single PDF for signing or filing.
• Receipts and invoices — bundle a month of captures into one file for bookkeeping.
• Portfolios — assemble artwork scans with uniform A4 pages and consistent margins.
• Print handouts — lay images out on Letter or A4 with a safe margin for printers.

Why it stays private

The PDF is assembled by pdf-lib inside this tab — the image bytes are read into memory and written straight into the document. Nothing is uploaded, so confidential scans and personal photos stay on your device.

FAQ

Q: Which image formats can I use? A: PNG and JPEG, the two formats pdf-lib embeds directly. Convert WebP, GIF or HEIC files first.

Q: How are images placed on the page? A: Each image is scaled to fit inside the page minus the margin and centered. With the image size option, the page equals the image pixel dimensions.

Q: Is there a page limit? A: Fifty images per run keeps memory predictable on phones. Run again for more pages.

Q: Can I add password protection? A: No. pdf-lib builds a plain, unprotected PDF; add encryption in a dedicated tool if you need it.
