How to convert images to PDF

1

Drop your images

Drag multiple JPG, PNG or WebP files at once. They all load in your browser — nothing goes to a server.

2

Set order

Rearrange the order if needed — drag to reorder. What you see is what goes into the PDF.

3

Pick page size

Choose A4 or Letter depending on what you need the PDF for.

4

Download PDF

Click Convert and get your PDF instantly. Each image becomes a page.

When do you actually need image-to-PDF?

A lot more often than you might think. Scanned documents. Photos of receipts. Product shots for a client. Multiple screenshots that need to go into one file. A form that only accepts PDF.

The problem is most tools that do this upload your files. You drag in your images, they go to a server somewhere, the server converts them, you get a download link. That is fine until those images contain anything personal — a bank statement, an ID, a medical photo, a contract.

This tool does it entirely in your browser using the PDF generation library and the Canvas API. Your images never leave your device. The PDF is generated locally and downloaded directly to your machine.

What decides the size of the PDF

This tool places each image on its own A4 page and stores it as a JPEG at 92 percent quality, at the image's full resolution. At that quality a photo is visually indistinguishable from the original, and the PDF ends up roughly the combined size of the images, give or take.

The most effective way to get a smaller PDF is to shrink the images before they go in. A photo straight from a phone is often 4000 pixels wide, far more than an A4 page needs, and reducing it first can cut the PDF size by more than half with no visible difference on the page.

Printing at home1754 pxA4 at 200 DPI, good enough for text and photos on office paper

Page size, orientation and how the image is fitted

Every page this tool creates is A4. Each page takes the orientation of its own image, landscape for wide pictures and portrait for tall ones, and the image is scaled to fit inside the page and centred, so nothing is ever cropped.

When an image is a different shape from A4, the leftover space shows as white margins on two sides. A document that mixes wide and tall pictures still keeps every image as large as the page allows, because the orientation is chosen per page.

DPI is a label, not a quality setting

DPI describes how many pixels are packed into each printed inch. It does not exist inside the pixels themselves. The same 2480 pixel wide image is 300 DPI when printed at A4 width and 150 DPI when printed at twice that size. Changing the DPI number without changing the pixel count changes the intended print size and nothing else.

This is why asking for a 300 DPI PDF is only meaningful alongside a physical size. What actually determines print sharpness is the pixel count relative to how big the page will be.

Scans, photos of documents and file size

A phone photo of a printed page is a photograph, and photographs compress badly compared to text. A page of black text on white captured as a JPEG carries sensor noise in every white area, and that noise is expensive to store.

Two things help a great deal. Converting the page with the grayscale tool removes the colour channels, which carry nothing useful for a black and white document. Raising the contrast with the adjust tool so the paper goes properly white gives the compressor large flat areas to work with. Together they often cut the size of a document scan by more than half with no loss of legibility.

FAQ

Can I add multiple images?+
Yes — unlimited. Add as many JPG, PNG or WebP files as you need. Each becomes its own page in the PDF.
What PDF page size can I use?+
A4 and Letter. A4 is the standard in most of the world. Letter is the US default. Pick whichever suits your use case.
Is image quality preserved?+
Yes. Images are embedded at their original resolution. There is no re-compression step that degrades quality.
Can I compress the PDF?+
Not directly through this tool. If you need a smaller PDF, compress your images first using the image compressor, then convert to PDF.
Does it work on mobile?+
Yes, fully mobile compatible. The tool runs in your browser so any modern phone or tablet works fine.
Why is my PDF larger than the images I added?+
Each image is stored at full resolution as a high quality JPEG, so a PDF of large phone photos is large. Shrinking the images before converting is the most effective way to make it smaller.
What image size should I use for a printable PDF?+
About 2480 pixels on the long edge for A4 at 300 DPI, or 1754 pixels for a good home print. For on screen reading, 1240 pixels is plenty and keeps the file small.
Does converting to PDF reduce image quality?+
Very slightly at most. Each image is saved as a JPEG at 92 percent quality, which is visually indistinguishable from the original for photos. Transparent areas in a PNG are filled with white, because JPEG has no transparency.
Can I put several images on one page?+
This tool places one image per page, which suits photos, scans and receipts. For a contact sheet style layout, merge the images into a single picture first and then convert that.
How do I make a scanned document much smaller?+
Convert it to greyscale and raise the contrast before converting. A photo of a printed page stores sensor noise across every white area, and removing the colour channels plus flattening the background often halves the size with no loss of readability.
