Images to PDF — batch convert, entirely in your browser
Scan contracts, collect receipts, bundle photos into one document — without handing any of them to a converter website. Drop images in, arrange the page order, build the PDF. JPEG files go in byte-for-byte.
Drop images here to build a PDF
JPEG, PNG and WebP work everywhere. The files are read in your browser — this page has no upload endpoint at all.
Pages, in order

HEIC to JPG →Why a browser-side images-to-PDF converter exists
The usual way to combine photos into a PDF is a converter website: you upload the images, the server builds the file, you download it. For a receipt or a scan of an ID card, that means trusting whoever runs the site with exactly the documents people least want to leak. This page flips the model: the PDF is assembled by JavaScript in your browser, from files it reads off your disk, and the result is written straight back down. There is no upload endpoint to trust.
That is not a promise you have to take on faith. The same site publishes a measured upload test: nine popular image tools were watched at the network level with a marked file, and two were caught transmitting the whole thing. The method, scripts and raw results are on the page so anyone can re-run the probe — including against this site.
How the PDF is put together
| Input | What happens to it |
|---|---|
| JPEG / JPG photos | Embedded byte-for-byte — the PDF contains your original compressed pixels, untouched |
| PNG and WebP images | Drawn to a canvas once and encoded as high-quality JPEG (quality 92) — the format PDF embeds directly |
| HEIC (iPhone) | Decoded by Safari only; other browsers should convert first with HEIC to JPG |
Page sizing works two ways. Fit each image gives every photo a page shaped exactly to its aspect ratio at print resolution — the natural choice for photo albums and full-page scans. The fixed sizes — A4 and US Letter, portrait or landscape — centre each image on the page at the largest size that preserves its shape, which is what schools, offices and government portals usually expect from uploaded documents.

Shrink photos before bundling them with the main compressor; hit an exact size with compress to 100 KB; make images an exact pixel size with the batch resizer; and check what metadata your photos carry with the EXIF viewer — a PDF built here keeps the JPEG bytes it was given, so stripping GPS from the photos before building is the move if the document will be shared.
Frequently asked questions
Are my images uploaded when I build a PDF here?
No. The files are read with the browser's own File API and the PDF is assembled by JavaScript on your device. This site has no upload endpoint at all — the network tab shows nothing leaving the browser.
What page sizes can the PDF use?
Fit-each-image gives every photo its own page shaped exactly to the picture (best for photos and documents you want at full quality). A4 portrait, A4 landscape, US Letter portrait and US Letter landscape place each image inside the page, centred, at whatever size preserves its aspect ratio.
Does converting images to PDF reduce their quality?
JPEG files are embedded byte-for-byte — the pixels in the PDF are exactly the pixels you gave it, no re-compression. PNG and WebP files are converted to high-quality JPEG first, because the PDF writer embeds JPEG directly; the quality setting is 92 out of 100, which is visually indistinguishable for photographs.
Can I rearrange the page order?
Yes. Every image in the list has up and down arrows, and the PDF's page order follows the list order exactly. The thumbnails show you what each page will look like before you build.
Why will my iPhone HEIC photo not load?
Browsers other than Safari cannot decode HEIC files, so the image cannot be drawn into the PDF there. Convert it first with the HEIC to JPG tool on this site — it also runs entirely in the browser — then add the JPG here.
How many images can one PDF hold?
There is no artificial limit; the practical limit is your device's memory, since everything is processed locally. Scans and photos in the tens of images work comfortably on an ordinary laptop. Each image keeps its own full resolution, so a 50-photo PDF is roughly as large as the 50 photos combined.
