Visual page ordering
Thumbnails make the sequence obvious before you commit. Drag to reorder rather than counting file names and hoping.

Overview
About the JPG to PDF Converter
Create a PDF from JPG, PNG or WebP images. Reorder pages by drag-and-drop, choose page size, orientation and margins — built locally with pdf-lib.
Building a PDF out of images is how scans, receipts, signed pages and photo collections become documents that can be attached, filed and printed reliably. It is also the format that survives every email system and portal without complaint.
Page sizes and what they mean
PDF measures pages in points, at 72 points per inch:
Choosing a standard size rather than "fit to image" is what makes a document printable. A PDF whose pages are the exact dimensions of your phone photos will print unpredictably.
Fit, Fill and Stretch
Fit scales the image down until it fits entirely within the printable area, preserving proportions and adding white space where needed. This is the safe default and the correct choice for scanned documents where every edge matters.
Fill scales the image up until it covers the whole page, cropping whatever overflows. Useful for full-bleed photo pages, dangerous for documents — it will silently cut off a signature or a page number.
Stretch forces the image to the page dimensions, distorting it. Only use it when the source aspect ratio already matches and you want zero margins.
Margins and DPI
A 0.5-inch margin on A4 gives a printable area of about 523 × 770 points. An image 1600 pixels wide fitted into that area lands near 220 DPI, which prints cleanly. Below roughly 150 DPI, text in the image starts to look soft on paper — so if print quality matters, source images of at least 1200 pixels on their short edge.
Step by step
How to use the JPG to PDF Converter
Add your images — they appear as thumbnails in the order they will be placed.
Drag thumbnails to reorder, or remove any you do not want.
Choose a page size (A4, Letter, Fit to image) and an orientation.
Set margins and whether images should be stretched or fitted.
Press Create PDF and download the finished document.
Why use it
Benefits and common use cases
What this tool is good for, and what it deliberately does not try to do.
Real page geometry
Proper A4, Letter, Legal or A5 pages with configurable margins — the output looks like a document, not a pile of pictures.
Fit, fill or stretch
Fit preserves the aspect ratio with white space, Fill crops to cover the page, and Stretch distorts to match exactly. Fit is the right choice almost every time.
Embedded, not linked
Images are embedded into the PDF, so the document is self-contained and will open identically on any device, forever.
Questions
Frequently asked questions
Short, honest answers about quality, limits and privacy.
Which image formats can I use?
JPG and PNG are embedded directly. WebP and other formats are re-encoded to JPEG or PNG first so the resulting PDF opens in every reader, including older ones without WebP support.
Will the PDF be bigger than the images?
Roughly the same. JPEG and PNG data is embedded without recompression, so the PDF size is close to the sum of the image sizes plus a small amount of document structure.
How do I get the images in the right order?
Files are added in the order you select them, and most file pickers respect name order. After adding, drag the thumbnails to rearrange. Numeric prefixes like 01-, 02- are the most reliable way to pre-sort before uploading.
Can I mix portrait and landscape images?
Yes. Choose the Fit to image page size and each page takes the dimensions and orientation of its own image, so a mixed set produces a correctly-shaped document.
Are the images compressed?
Not by default — the original image bytes are embedded. If you need a smaller PDF, compress the images with the image compressor first; you get far better control over the quality trade-off that way.
