Image to PDF Converter

How this image to PDF converter works

Drop any mix of JPG, PNG, WebP, HEIC or AVIF files above, put them in order with the arrows, pick a page size and click Create PDF. This image to PDF converter builds the document right in your browser using a small PDF library: each image becomes one page, and the finished file is handed to you as a download. No upload, no account, no watermark. JPG files are placed into the PDF byte for byte, so they are not re-compressed; PNG files are stored losslessly. WebP, HEIC and AVIF images are first decoded by your browser and converted to PNG on the way in, so they come through at full quality too.

A JPG photo whose EXIF data says "rotate me" (common with phone cameras) is rotated for real before it goes in, because PDF viewers ignore EXIF and would otherwise show it sideways.

Page size, orientation and margins

Fit to image makes every page exactly the size of its image, one pixel per PDF point, with no scaling. It is the best choice for screenshots, scans and anything you will view on screen, and it is what most "jpg to pdf" tools do by default. A4 and Letter give you a real paper size: the image is scaled down (never up) to fit inside the margins and centered, which is what you want when the PDF will be printed or sent to someone who will. Orientation on a fixed page is automatic by default: wide images get a landscape page, tall ones a portrait page. The small margin is half an inch (36 points) on every side, enough to survive most printers' unprintable edge.

Worked example

Say you photograph four receipts with your phone. Each is a 3024 × 4032 HEIC of about 2 MB. Drop all four, choose Letter with a small margin, and click Create PDF. The decoder runs once, each photo is converted to PNG, and the result is a four-page, portrait, letter-size PDF of roughly 30 MB, because PNG keeps every pixel. If 30 MB is too big to email, convert the photos to JPG first with the HEIC to JPG converter at 80% quality, then build the PDF from those: the same four pages come to about 3 MB.

Why size changes the way it does

A PDF is a container, not a compressor. The PDF will be roughly the sum of the images inside it plus a few kilobytes of structure. Shrink the images and the PDF shrinks; choosing A4 over Fit changes the page dimensions but not the embedded image data, so the file size barely moves. If you need a smaller PDF, reduce the image quality or resolution before converting.

Privacy

Receipts, IDs, signed forms and whiteboard photos are exactly the kind of images people turn into PDFs, and exactly the kind that should not sit on a converter's server. Everything here, from decoding to writing the PDF bytes, happens inside your browser tab. You can load the page, disconnect from the internet, and still create the file. Once you close the tab, nothing remains. The related Merge PDF and Split PDF tools work the same way if you need to combine this PDF with others or pull pages back out.
