Image to PDF

Common questions

How do I turn several photos into one PDF?

Drop the pictures onto the stage, or press Add images and choose them. Each one appears in the Images panel with its shape and its size, and the Pages panel fills with one page per picture, in the same order. Use the up and down buttons beside a file name to change that order, set the paper size, the orientation and the margin in the readout, then press Download PDF. The file downloads straight away and is also listed as a link with its page count and size, so you can save it again without building it twice. The PDF is named after the first picture in the list.

Can I choose the paper size and the margins?

Yes. Paper is Letter (612 by 792 points, which is 8.5 by 11 inches), A4 (595.28 by 841.89 points, which is 210 by 297 mm) or Fit image, which sizes each page to the picture itself at 96 pixels to the inch. The margin is typed in millimetres and is the same on all four sides. With Fit image the page grows by the margin rather than eating into the picture, so the picture lands at its own size with the margin exactly around it. Each page preview says the page size and the resolution the picture is printed at, in dots per inch, so you can see what a bigger margin costs before you build the file.

Will my landscape photos be rotated or squashed?

Neither. The scale is one number applied to both sides, so the proportions survive every paper size and margin: nothing is stretched, and because the picture is fitted whole rather than filled to the edges, nothing is cropped either. On Auto, the page follows each picture's own shape, so a wide photo gets a wide page and an upright one gets an upright page in the same document. Portrait and Landscape override that for every page if you want a single shape throughout, and a picture that does not match the page it is given is still fitted whole, with the leftover space as background.

What happens to a PNG with a transparent background?

This tool flattens the image onto a page background. If any picture has see-through pixels, choose White, Black or your own colour before downloading. The chosen colour fills both the image background and the margins. PDF can support transparent image content, but this converter deliberately writes a flat page and does not preserve PNG alpha in its output.

Are my images uploaded anywhere?

No. The pictures are read in the page, decoded by this browser, redrawn onto a canvas and written into a PDF here in the tab. There is no endpoint to send them to, and no picture byte is passed to analytics or error reporting either. Nothing about their contents is written to your browser's storage; only the layout settings are remembered between visits, as the note under the tool lists.

Which picture formats work?

JPEG, PNG, WebP and AVIF work when the browser can decode them; GIF and BMP are also commonly readable. Animated inputs become a still picture, not a moving PDF. JPEG, WebP and AVIF are re-encoded as JPEG at quality 92; PNG and other readable formats use PNG after drawing onto the page background. No original image file is embedded byte for byte. TIFF, HEIC and HEIF support is not guaranteed by browser decoding, so export a JPEG copy first. For a multipage TIFF, see the TIFF to JPG steps in the TIFF question further down this page.

How many images can I put in one PDF, and how big can they be?

Up to 50 images, 50 MB in total and 40 megapixels per picture. A source over 16 megapixels is proportionally redrawn to about 16 megapixels for export. These are this tool's processing bounds; browser and device limits vary. A file count, byte total or pixel count above a limit blocks the build with the reason. An unreadable image is listed as skipped, so check the list before downloading.

Can I reorder or remove pictures before building the PDF?

Yes. Every picture in the list has a move earlier button, a move later button and a remove button, each labelled with the file name, so the whole list is operable from the keyboard and focus follows the picture you moved. The page previews and the page count update as you go, and a long build can be cancelled while it runs: cancelling stops before anything is written, so there is no half-finished download to throw away.

Can I convert images to PDF on an iPhone, Android phone, Mac or Windows computer?

Open this page in a current browser, choose the saved images, check their order and download the PDF. Choose that downloaded file when sharing or attaching it. If a phone photo is HEIC and will not open, export a JPEG copy first. The page does not install a native app, send an email or synchronize your photo library.

Does a scanned image become searchable or editable text?

No. Converting a photo of text into a PDF keeps the text as pixels. For a searchable PDF of printed English, create the PDF here and then use Searchable PDF OCR; check the recognized words and that tool's limits. For editable Word text from a JPG or PNG, use Image to Word. OCR does not reconstruct the original fonts, tables or layout.

Can I scan paper or straighten a phone photo before making the PDF?

This converter packages saved pictures into pages and does not control a scanner, detect paper edges or correct perspective. Use Document Scanner to capture or load a page photo, place its four corners, adjust contrast and export a PDF. A flat scan already saved as JPG or PNG can be combined directly here.

How do I turn a multipage TIFF into one PDF?

Open the TIFF in TIFF to JPG and export the readable pages as PNG or JPEG. If it returns a ZIP, extract the files first. Add the page images here in their numbered order, review the page list and download one PDF. Both tools have input limits, and an unsupported TIFF compression cannot be recovered by this sequence. The PDF conversion re-encodes the page images, so it does not preserve the TIFF container, original compression or all metadata.

Can I insert, replace or remove a picture in an existing PDF?

This page creates a new PDF from image files; it does not edit objects inside an existing document. To add pictures to an existing PDF as extra pages, make a PDF of them here, then choose it together with the existing document in PDF Merger, move the new pages to where they belong and create one file. Placing a picture on top of an existing page, such as a logo or a signature, replacing a picture, or editing the text and layout is a different job and is not supported here. To save an existing PDF page as a picture, use PDF to Image. To retrieve its stored image objects, use PDF Image Extractor. To turn the pages of an existing PDF into an image-only PDF, use the Raster mode of PDF Flattener, which redraws each chosen page as one picture and keeps its page size.

How do I make the resulting PDF fit an upload limit?

Create and download the PDF first, then open it in PDF Compressor and enter the required size. A PNG-heavy document can be large, while raster compression can reduce it at the cost of detail. Check the final byte count and readability. This converter has no target-byte control and does not guarantee a PDF below 100 KB, 200 KB or another limit.
