JPG to PDF: convert images to PDF

Turn JPG, PNG and phone photos into one PDF

This JPG to PDF converter combines several images into a single PDF file, one image per page. It takes JPG, PNG, WebP, GIF (still image) and AVIF when your browser can open it, up to 100 images per PDF. You set the page order, paper size, margins and file size, then download the result.

It helps whenever a form asks for "one PDF file": a rental application with photographed pay stubs, receipts for an expense report or an insurance claim, signed forms, handwritten homework to upload to a school portal, tax documents for your accountant. A PDF keeps the pages in order and goes out as one attachment instead of a dozen photos.

How to use it

1. Click "Choose images" or drop your files into the box. You can also paste a copied image.
2. Under "Your pages", each image shows on a small sheet exactly as it will look in the PDF. Drag the ⠿ handle to change the order, or Tab to the handle and use the left and right arrow keys. ↻ rotates the image by 90°, × removes it.
3. Pick the "Page size", "Orientation", "Margins" and "Scaling".
4. To keep the file small, choose a "Resolution" of 150 or 300 dpi and adjust the "JPEG quality". The estimated PDF size appears under the buttons.
5. Type a "File name" and click "Create PDF". The download starts right away.

Your settings are remembered on your device for next time.

Page size, orientation and margins

US Letter (8.5 × 11 in) is the default here and what American offices and printers expect. A4 (210 × 297 mm) is the standard almost everywhere else, so use it for documents sent abroad. A5 suits small items such as a card or a ticket. With Image size, every page takes the exact proportions of its image: a 1,200 × 600 pixel picture gives a 12.5 × 6.25 in page with no white bands.

Automatic orientation puts a wide photo on a landscape page and a tall one on a portrait page. "Portrait" or "Landscape" applies to every page. Margins are 10 mm ("Small", about 0.4 in) or 20 mm ("Large"). "Fit" shows the whole image, centered; "Fill the page" covers the printable area and crops whatever sticks out.

Making the file smaller

A 4,000 × 3,000 pixel phone photo often weighs several megabytes, and ten of them can exceed an upload limit. On a landscape Letter page with small margins, that photo is printed at about 10.2 × 7.7 in. At 150 dpi, 1,532 × 1,149 pixels are enough to fill that area, roughly seven times fewer pixels than the original; at 300 dpi it takes 3,064 × 2,298. As a rule of thumb, 150 dpi is usually enough for reading on a screen, while 300 dpi generally gives a sharp print.

"Keep original JPEGs without recompressing" copies your JPEG files unchanged when no reduction is needed, so no quality is lost. PNG, WebP, GIF and AVIF images are always converted to JPEG.

Photographing documents with your phone

• Lay the sheet flat near a window in daylight and turn the flash off: it leaves a glare spot that hides text.
• Hold the phone parallel to the page to avoid a skewed, keystone shape, and frame the whole document with a little background around it.
• Zoom in to check sharpness before moving to the next page.

Privacy

Your images are read and assembled by your browser and never leave your device, which matters for a driver's license, a bank statement or a tax form. Photo metadata (camera model, date, GPS location) is not copied into the PDF, and the file carries no author name.

Frequently asked questions

Are my images uploaded to a server?

No. All the work happens in your browser, on your computer or phone.

How many images can I put in one PDF?

Up to 100 images, each no larger than 100 MB and 50 megapixels. Extra files are skipped and a message tells you so.

What happens to a transparent PNG background?

The JPEG format used inside the PDF has no transparency, so transparent areas turn white, like paper.

Can I put several images on one page?

No, the tool places one image per page. For the front and back of an ID card, photograph both sides next to each other in a single shot.
