Any mix of images, one PDF
A stack of separate JPGs is awkward to send, easy to get out of order, and often not what a form or a client asked for. One PDF fixes all three: a single attachment, pages in a fixed sequence, and a format (ISO 32000) that looks the same on any computer or phone.
You aren’t limited to JPG. Drop JPG, PNG, WebP, AVIF and iPhone HEIC files into the same batch and you get one combined PDF, one image per page. That helps when your pictures come from different places, such as phone photos, screenshots and images saved from the web.
Create the PDF in four steps
- Add your images. Select files, drag in a folder (subfolders included), or paste from the clipboard. Up to 500 per batch.
- Pick a page size: Letter, A4, or Fit to photo.
- Pick an order: by date taken, by file name, or in the order added.
- Convert and download the PDF. Not happy with the layout? Change the page size or order, and the PDF is rebuilt without converting the images again.
Your JPGs go in untouched
A JPG that is already upright and isn’t being resized goes into the PDF without being decoded or re-encoded: its compressed image data is copied byte for byte, so there’s no generation loss and the picture on the page is exactly the one you started with. Only the metadata block is left behind — EXIF details such as GPS coordinates and camera settings aren’t copied into the PDF. Two situations do require re-encoding:
- Rotation. Phone photos are often stored sideways, with an orientation tag telling viewers to turn them. Those are rotated upright for the page, which means re-encoding.
- Resizing. If you set a maximum size (4096, 2560, 1920 or 1280 px on the long edge), larger images are scaled down and re-encoded.
PNG, WebP, AVIF and HEIC images are decoded first, then written into the PDF in a form every reader can display; for HEIC photos, the original ICC color profile comes along, so iPhone colors don’t look faded. One thing never makes it into the PDF: EXIF metadata. Date taken, camera details and GPS location stay behind, which is a privacy plus when sharing photos taken at home.
Page size, margins and orientation
| Option | Layout | Good for |
|---|---|---|
| Letter (default) | 8.5 × 11 in, 0.5-inch margins, portrait or landscape per image | Printing and forms in the US and Canada |
| A4 | 210 × 297 mm, 0.5-inch margins, portrait or landscape per image | Printing and forms almost everywhere else |
| Fit to photo | Each page matches the image’s own shape | Portfolios, photo sets, reading on screen |
Because orientation is picked per image, a wide panorama and a tall receipt can share one PDF, each on a page turned the right way. For a portfolio, Fit to photo gives every page the picture’s own proportions instead of a fixed paper shape, so wide and square images aren’t surrounded by empty space.
Scanning paperwork with a phone
You don’t need a scanner to turn paper into a decent PDF. A few habits get phone shots much closer to a real scan:
- Lay the page flat on a plain, dark surface so its edges stand out.
- Use even light and keep your own shadow off the page; skip the flash if it leaves a glare spot.
- Hold the phone directly above the page and parallel to it, so lines stay straight.
- Fill the frame. Each image is placed on the page as it is, so whatever surrounds the paper ends up in the PDF.
- Shoot pages in order; sorting by date taken then sequences them automatically.
Before sending, zoom in on the smallest print in the PDF to make sure it’s legible.
How big will the PDF be?
When your JPGs are embedded unchanged, the PDF is roughly the sum of the image files plus a little overhead. Twenty full-resolution phone photos make a correspondingly large file: fine for an archive or a portfolio, often too much for email or an upload portal.
For a smaller PDF, set a maximum size before converting. A 1920 px long edge keeps documents and photos clear on screen and in normal prints; 1280 px suits strict limits, but check that small text still reads.
Already have a PDF that’s too large? Compress PDF re-encodes the JPEG photos inside it at a lower resolution and quality, with Light, Balanced and Strong presets, and never hands back a file bigger than the original.
Next steps, limits and privacy
To attach this PDF to others, such as a cover letter or an earlier report, use Merge PDF; pages are copied unchanged, so text stays selectable. To pull a few pages out of a long PDF, use Split PDF.
- No OCR: text in your images isn’t searchable or selectable in the PDF.
- No editing, signing or password protection.
- 500 images per batch, a technical limit that keeps the browser responsive.
- Videos are skipped, and HDR photos become standard dynamic range.
- Works in recent Chrome, Edge and Firefox, and Safari 16.4 or later.
If you need separate image files rather than a document, convert instead, for example with HEIC to JPG.
Your images never leave your device. Everything runs in the browser tab, the page’s Content-Security-Policy only allows connections to pd00.com and a cookieless visit counter that never receives your images, and once loaded you can go offline and keep working. Here’s how to check it in DevTools.
