Resize Images to PDF

Combine photos into one PDF and shrink them on the way: choose the longest side and the JPEG quality, and see how much smaller the result is. Everything happens in your browser.

How to resize images into a PDF

PDFDistrict redraws each image at the longest side you choose (it never enlarges), saves it as a JPEG at your chosen quality and places it on its own page, in the order you added them. Smaller dimensions and lower quality give a lighter PDF; a message shows the total size before and after.

Practical use cases

Making a photo PDF small enough for an upload limit.
Sending phone photos of a document without a huge attachment.
Combining a batch of pictures into a lightweight PDF.

What changes in your images

Every image is saved as a JPEG, so transparent areas of a PNG become white. Lower quality and smaller dimensions reduce size but also detail; try the defaults first (2000 px, 75%).

Common problems

The PDF is still large: lower the longest side or the quality, or use fewer photos per file.
Text in a photographed document looks soft: raise the quality or the longest side; text needs more resolution than a landscape photo.
A photo appears sideways: the image’s orientation data decides how it is drawn; rotate the photo in a photo app first if needed.
