PDFs
JPG to PDF
Combine JPG and PNG images into one PDF. Keep each picture at its own size, or fit every page on A4. The document is built in your browser.
This file never leaves your device. The tool runs in your browser.
How to use it
- Drop one or more images, in the order you want the pages.
- Choose original size or A4.
- Build the PDF.
- Download it. Reorder by dropping files in the right order.
Three phone scans
Three portrait photos set to A4 become a three-page PDF. Each photo is scaled to the page and centered, with white paper around it if the aspect ratio is not A4.
This is the practical way to send a stack of scans or phone photos as one attachment. Original size uses each image’s pixel dimensions as the PDF page, which is ideal for screenshots. Fit on A4 scales each picture onto an A4 page with a small margin and centers it, which prints cleanly. WebP and HEIC should be converted to JPG first. The PDF stores JPEG data, so transparent PNG areas are placed on white.
Questions
Can I put several images in one PDF?
Yes. Drop them together. The page order follows the order of the files you added.
What is the difference between original size and A4?
Original size makes the PDF page match the image. A4 fits the image on a standard page for printing.
Is my file uploaded?
No. The file is read in your browser and processed on this device. ProHacks does not receive the photo or the PDF.
Is there a page limit?
There is no fixed count. Very large batches are limited by your device’s memory. If a build fails, split the set in half and merge the PDFs afterward.
