PNG · JPG · WEBP → PDF
Image to PDF converter
Drop any mix of images and get a single PDF back, one picture per page, in the order you added them. The file is assembled in this tab, so a private scan or a client's artwork never leaves your device.
JPEG files are embedded byte-for-byte, so their quality is untouched; every other format is decoded, laid on white and stored losslessly. Transparency cannot survive into a PDF page, and the page size you pick frames each picture.
How to convert images to PDF
Add the images
Drop a mix of formats at once, or pick them from disk. Page order is the order you added them, so the cover image goes in before the rest.
Set the page
Choose A4, US Letter or fit-to-image and set the margin in points, where 72 points equal an inch. Fit gives every page the shape of its own picture; A4 and Letter give the document a single shape.
Convert and download
Save the finished PDF. JPEGs pass through as they arrived, while PNG, WEBP, SVG, GIF, BMP and AVIF are decoded once and written in losslessly.
Two paths into one PDF
A PDF page is a fixed box with drawing instructions, and an image can enter it in two ways. This tool takes the cheap path for JPEG: the compressed stream is copied into the file as it stands, so the photo is neither decoded nor re-encoded and its size and quality are exactly what you had. Everything else — PNG, WEBP, GIF, BMP, AVIF and SVG — has to be decoded to raw pixels first: SVG is rasterised, GIF contributes its first frame, transparency is flattened onto white, and the pixels go in with lossless Flate compression.
That split decides the file size. A folder of JPEGs becomes a PDF about as large as the sum of its parts plus a few kilobytes of page structure, while a folder of PNG photographs becomes a much bigger document, because lossless storage cannot shrink a photograph the way JPEG does. Nothing is upscaled, EXIF data inside a JPEG is carried along but not rewritten, and a PDF page has no alpha channel, which is why the flattening step is unavoidable for formats that do.
Image to PDF questions
Where do my images go during the conversion?
Nowhere. They are read from your disk, decoded and laid out as pages inside this tab, then written back to your disk as one PDF, so no upload happens and no copy is kept anywhere. There is no sign-up and the page continues to work offline after the first load.
How do I know which path my file took?
The rule is the format, not the file name: JPEG files — including .jfif and .jpe — are embedded byte-for-byte, and PNG, WEBP, GIF, BMP, AVIF and SVG are decoded and stored losslessly. Either way no new compression loss is introduced, so the quality in the PDF is the quality the image already had when you dropped it.
Which page size should I pick for a printed document?
A4 is 595 by 842 points and US Letter is 612 by 792 points, with 72 points to the inch, so the two differ by a few millimetres on each edge. Choose the size your printer is loaded with, and set a margin of 36 points or more to keep pictures clear of the paper edge.
Is there a limit on how many images I can combine?
Each input file must be under 64 MB, and the page count is bound by your browser's memory rather than by the tool, since every page is held in the tab until the PDF is saved. A few hundred JPEG pages are entirely practical; a few hundred lossless pages are not, so keep the heavy formats for short documents.
