How to convert JPG and PNG images to one PDF

Last updated: 1 November 2026

To convert JPG images to PDF, open JPG to PDF, select your images, drag them into order, choose a page size and click “Convert to PDF”. You get one PDF with one image per page, or a separate PDF for each image if you prefer.

This guide is for anyone who needs to send photos of receipts, ID cards, homework, handwritten notes or signed forms as a single document. It covers page sizes, margins and image quality, how to do it on a phone, and what to do when the finished PDF is too big to upload or email.

Open JPG to PDF

Step by step

  1. Select your images. Open JPG to PDF and click “Select images”, or drop JPG, PNG, WebP, GIF or BMP files onto the page. You can add more images at any time.
  2. Put them in order. Drag the images into the order you want, use the arrow buttons, or sort them by name. Each image becomes one page in this order.
  3. Choose the page size and orientation. Keep each page the same size as its image, or pick A4, US Letter, A3, A5 or US Legal. With a standard size, also choose the orientation you want.
  4. Set a margin. Pick a margin preset or enter your own value in millimetres. A small margin leaves white space around each image, which helps when you print.
  5. Decide on one PDF or several. Leave “Combine all images into one PDF” ticked for a single file. Untick it to get a separate PDF for each image.
  6. Convert and download. Click “Convert to PDF”, then “Download”. If you made one PDF per image, you can download them together as a ZIP.
  7. Compress if needed. If the file is too big for an upload form or email, open it in Compress PDF and start with “Recommended”.

Which page size and margin to choose

“Same as image” makes each page exactly the size of its picture. This is best when the PDF will only be viewed on screen, because there are no empty borders.

Choose a standard size when the PDF will be printed or uploaded to a form that expects standard pages:

  • A4 or US Letter for most documents, receipts and forms.
  • A3 for large images you want to print big.
  • A5 for small documents.
  • US Legal when a form or office asks for legal-size pages.

With a standard size, set the orientation to match your images and add a margin, either from the presets or in millimetres.

Image quality and file formats

JPG images are copied into the PDF exactly as they are, without being re-compressed, so the PDF looks like your original photos. PNG images are stored without loss too, and PNG transparency is kept.

WebP, GIF and BMP files are converted on your device first. For an animated GIF, only the first frame is used.

HEIC photos from an iPhone are usually handed over as JPG automatically when you pick them in the browser.

Because nothing is re-compressed, a PDF made from large phone photos can be big. That is the trade-off for keeping full quality, and it is why the last step points you to compression.

Converting photos to PDF on a phone

Open JPG to PDF in your phone’s browser, tap “Select images” and pick photos straight from your gallery or files. Tap “Convert to PDF”. The PDF is created on your phone and saved to your downloads.

Photos taken with a phone are turned the right way up automatically. This makes it easy to turn photographed ID cards, mark sheets, receipts or signed forms into one PDF ready for an online form or email.

When the PDF is too big, or you need to add other files

  1. Recreate the PDF with A4 and a small margin.
  2. Open the result in Compress PDF and choose “Recommended”.
  3. If a form still says the file is too big, try “Extreme compression”, or set the image resolution and JPEG quality under “Advanced settings”.
  4. For documents you will print in black and white, tick “Convert to grayscale” to save more space.

To combine your images with existing PDFs, such as a CV and scanned certificates, make the image PDF first, then put all the files together with Merge PDF.

Frequently asked questions

Will my images lose quality when I convert them to PDF?

No. JPG images are copied into the PDF unchanged and PNG images are stored without loss. Quality only changes if you later run the PDF through Compress PDF, which resizes and re-compresses large images.

Are my photos uploaded anywhere?

No. Your images are converted by your own browser and are never uploaded, so private photos and scanned documents stay on your device. There is no account or sign-up.

How many images can I put in one PDF?

There is no fixed limit and no daily limit. Dozens or hundreds of images work fine; the only limit is your device's memory.

Can I convert HEIC photos from my iPhone?

HEIC photos from an iPhone are usually handed over as JPG automatically when you pick them in the browser, so you can select them as usual.

Can I make a separate PDF for each image?

Yes. Untick “Combine all images into one PDF” before you click “Convert to PDF”. You get one PDF per image and can download them together as a ZIP.

How do I make the PDF smaller for an online form?

Create it with A4 and a small margin, then open it in Compress PDF. Start with “Recommended” and switch to “Extreme compression” if the form still rejects the file.
