Frequently Asked Questions
Can I put several JPGs into one PDF?
Yes. Each image becomes one page, in the order shown in the list.
Which page size should I pick?
A4 suits most forms and printing. Letter is common in the US. Fit to image makes each page exactly the image's proportions.
Are my photos uploaded?
No. The PDF is built entirely in your browser; images never leave your device.
Does the tool reduce photo quality?
Images are embedded at their original quality - they are scaled to fit the page, not re-compressed.
How it works
Each image you add is embedded into a new PDF inside your browser with pdf-lib - your photos are never uploaded. JPEG files are stored exactly as they are, byte for byte, with no re-encoding, and PNG files are embedded losslessly, so the pictures in the PDF are identical to the originals. Every image becomes one page, in the order of your list. You choose the page size - A4, Letter, or Fit, which makes each page exactly the image's size - the orientation, and a margin; each photo is then scaled to fit inside the page and centred. The finished file downloads as images.pdf.
Worked example
You photographed a six-page paper form with your phone and the office asks for a single PDF. You add the six photos, keep page size A4 with Auto orientation and the Small margin, and click the button: images.pdf arrives with one photo per A4 page, each fitted neatly inside the margins, in the order you took them.
Frequently asked questions
Can I use PNG images as well as JPG?
Yes. Despite the tool's name, the picker accepts both JPG and PNG files, and they can be mixed in one list - JPEGs are embedded as they are and PNGs are embedded losslessly.
How do I change the order of the pages?
Pages follow the order of the list, which is the order you added the images. There is no drag-to-reorder here: to move a photo, remove it with its Remove button and add it again so it joins at the end, building the order you want.
What does the 'Fit to image' page size do?
It sizes every page to its own picture - the image's pixels are converted at 0.75 points per pixel, the standard screen-to-print scale - so there are no borders and no empty page area around the photo.
How large are the margins in real terms?
Small is 28 points (about 10 mm) and Large is 56 points (about 20 mm) on every side. None places the photo edge to edge, though most home printers cannot print right to the paper's edge.
A photo from my phone appears sideways in the PDF - why?
The tool reads the image's stored pixel dimensions, and some phones store a photo sideways with a note about its real orientation that this simple embed does not apply. Rotate the photo in your gallery or photos app first, then add it again.
