Image to PDF — Free, Fast & Private

Drop images into the tool above and each becomes one page of a single PDF, in the order you added them. It accepts JPG, PNG and WebP, and HEIC iPhone photos too; the HEIC to PDF page covers that in detail. The PDF is built by jsPDF in your browser, so IDs, receipts and medical records are not uploaded.

Choosing a page size

Fit to image is the default and gives each page the shape and size of its own image, which suits photos. A4 and US Letter give every page exactly that page box, turned to landscape when the image is, with the image scaled to fit and centred. Nothing is cropped, so an image of a different shape leaves a white margin. Choose one when a portal validates A4, a print shop prices by sheet, or the document must print at actual size.

Order, limits and what is embedded

Pages follow your upload order. Each image can be up to 200 MB, with no daily quota or monthly credit, and one that is too large to decode safely in a browser tab is skipped with a note instead of failing the batch. A multi-frame file such as an animated GIF contributes only its first frame, and a JPG with a rotation tag is redrawn so it comes out upright. To keep a scan under a size limit, see JPG to PDF under 100KB and under 500KB, where the size target is set for you.

Round trip with PDF to image

Coming the other way, the PDF to Image tool offers Build a PDF from these pages on its results. Use that rather than downloading the pages and adding them back here, because it keeps the original page size: a PNG or JPG on disk carries no page box, so once pages are downloaded nothing in them says what size sheet they came from. For JPEG pages use PDF to JPG.

Measured 2026-10-07 in Chromium 145.0.7632.6 by building a one-page PDF from each file with this page’s tool at its default settings and reading the PDF it downloaded: its page size and how the image inside is stored, at what pixel size. The photos and scans are CC0 or public-domain files from Wikimedia Commons; the screenshot is MiniPx's own; the app icon is drawn by the measuring script, with a soft shadow so partial transparency is tested. Sizes are shown as the tool shows them (1 KB = 1,024 bytes).

Frequently Asked Questions

How do I combine multiple images into one PDF?
Select the Image → PDF tab, add your images in the order you want, and click Create PDF. Each image becomes one page.
Can the pages be A4 or US Letter?
Yes. The Page size control offers Fit to image, A4 and US Letter. A4 and US Letter give every page that page box with the image scaled to fit and centred, so nothing is cropped.
Does converting to PDF reduce image quality?
An upright JPG is embedded as it is, so the picture is not re-compressed. A JPG that carries a rotation tag, and formats a PDF cannot hold directly such as HEIC, AVIF and TIFF, are redrawn through a canvas and re-encoded, which is how a rotated phone photo comes out the right way up. Use the size-target pages if you need a specific KB limit.
Can I use this as a document scanner?
Yes. Photograph pages, receipts or forms with your phone, add them in order and create one PDF. Nothing leaves your device.
What happens to an animated GIF?
Only its first frame is used as the page.
