Convert JPG to PDF
Each photo becomes a page at its own pixel size — one PDF per image, or check a box and the whole batch lands in a single file. PNG and iPhone HEIC work too.

The expense system wants one PDF, not the five receipt photos on your phone. The course dropbox only takes .pdf. HR needs the front and back of your driver's license as a single attachment. This page turns the photos you already have into that file on your own device: the images are decoded and the PDF is written by your browser, so nothing is sent anywhere along the way.
Every image becomes one page, in the order you add it. With a single image you get a single PDF. With two or more, a checkbox labeled Combine all into 1 PDF shows up in the settings panel: check it and the whole queue comes out as one document; leave it off and each image gets its own PDF, which Download all (.zip) bundles into one archive.
JPG is the usual starting point, but PNG screenshots, WebP, BMP, GIF and iPhone HEIC go through the same queue. Two settings decide the size of the finished file: the Quality slider (82 by default) sets how hard each page is JPEG-compressed, and Max width (px) shrinks oversized phone photos before they become pages — often the difference between a file that clears a 5 MB cap and one that bounces.
How it works
PDF is preselected in the format bar; the only real decision is one file or many.
Add images in page order
Drag them onto the drop zone, click Choose images, or paste from the clipboard on desktop. Queue position is page position — select ten files at once and they arrive in the order your file picker listed them, so add them one at a time when the sequence matters.
Check Combine all into 1 PDF
The checkbox appears in the settings panel as soon as the queue holds two or more images and the format is PDF. While you are there, set Quality (60 is still crisp for paper documents) and a Max width in pixels if the file has to stay small.
Generate, check the size, download
Click Generate images. With the box checked you get one card named livreimage.pdf; unchecked, each image gets its own .pdf card and Download all (.zip) collects them. The file size is printed on every card before you save anything.
Each page is the exact pixel size of its image
There is no Letter or A4 option. A page is created at the pixel dimensions of its image — a 4032 × 3024 iPhone photo becomes a 4032 × 3024 page — and orientation follows the image: wider than tall is landscape, taller than wide is portrait. Nothing is cropped or padded, but the file carries no paper size.
You notice it when printing: the viewer warns the page will not fit. Pick Fit to page in the print dialog and it lands on Letter or A4 correctly. Any side over 10,000 px is scaled down to that limit before the page is built.
What makes the PDF heavy, and what fixes it
Every page inside the file is a JPEG re-encoded at the slider's quality, so size depends on two things: each image's pixel dimensions and that number. Three or four untouched phone photos push a combined PDF past 5 MB.
Quality 60 instead of 82 sheds a big share of the weight; black text on white paper tolerates it far better than skin or sky. Max width (px) is the bigger lever: capping the width at 1600 px cuts a 12 MP photo's pixel count by roughly three quarters while a letter-size page stays readable. Compressing the JPGs beforehand buys almost nothing — they are decoded and re-encoded here.
| Settings | Page from a 12 MP document photo | Good for |
|---|---|---|
| Quality 82, original size | roughly 2–4 MB | Archive copies, fine detail |
| Quality 60, original size | roughly 1–2 MB | Paperwork under a 10 MB cap |
| Quality 82, Max width 1600 | roughly 250–500 KB | Receipts and forms, 5 MB cap |
| Quality 60, Max width 1600 | roughly 150–300 KB | Long batches, 2 MB limits |
Page order, file names and transparent PNGs
Pages follow the queue: first added, first page. There is no drag-to-reorder, so if the back of your ID landed ahead of the front, remove it, add it again (it goes to the end) and regenerate. A combined file is always named livreimage.pdf; separate PDFs keep each image's base name.
Two things change silently. Camera metadata — GPS location, phone model, capture time — is dropped from every page, welcome when the recipient is a stranger. And a transparent PNG comes through with the see-through area filled white, because a JPEG page has no alpha channel.
What this page does not do
Many image-to-PDF searches end in a different need. Check before building a twenty-page file:
- No OCR: text stays part of the picture, not selectable or searchable with Ctrl+F.
- No merging of existing PDFs: only images enter the queue.
- No paper sizes, margins or several photos per page — Microsoft Print to PDF on Windows or Preview on a Mac do that.
- No edge detection or perspective correction like a scanner app: shoot the paper straight on, in even light.
- No passwords, page numbers, watermarks or PDF/A — fine for a receipt attachment, not a compliance archive.
Frequently asked questions
How do I put several JPGs into one PDF?
Add all of them, check Combine all into 1 PDF in the settings panel, and click Generate images. You get one file with one page per image, in the order you added them.
Can I reorder the pages?
Only by changing the queue: there is no drag handle. Remove the image that is out of place, add it again so it lands at the end, and click Generate again.
Why does the PDF open huge on screen and print cut off?
Because each page is sized in pixels to match its image, not to a sheet of paper. Choose Fit to page in the print dialog and it prints on Letter or A4 normally.
Will the text be searchable or selectable?
No. There is no OCR here; each page is a flat JPEG of your image, so Ctrl+F finds nothing and text cannot be copied. Fine for an attachment, not for a document someone needs to search.
The form says 2 MB max. How do I get a multi-page PDF under it?
Set Max width (px) to about 1600 and Quality to about 60 before generating; a phone photo of a page then lands around 150–300 KB, so five or six pages fit. Read the size on the result card and go lower if you need to.
Does it take iPhone HEIC photos directly?
Yes. The HEIC decoder (about 1 MB) downloads the first time you use it; after that each HEIC is decoded on your device and becomes a page like any JPG, with no separate HEIC-to-JPG step.
Are my receipts or ID photos uploaded to build the PDF?
No. Your browser decodes the images and writes the PDF itself. The first time you generate, it fetches the jsPDF library from a public CDN — that is code coming down, not your files going up.
Can I merge two PDFs I already have?
No. This page only builds PDFs from images (JPG, PNG, WebP, HEIC, BMP, GIF, SVG). An existing .pdf will not be opened.
