How to convert images to a PDF
Each image becomes one page, in the order you set. The reason to convert at all is usually not the picture — it is that forms, portals, and printers expect a document, and a folder of loose photos is not one.
Set the order and the page layout
Drag the images into sequence, rotate any that came in sideways, and remove or duplicate as needed. Then choose the page size, orientation, fit, margin, and background — or start from one of the presets and adjust.
Export one PDF
Download a single document with every image on its own page, in your order, with no watermark and nothing added to the pages.
PNG, specifically
Converting a PNG to PDF without surprises
PNG is the format most people arrive with, because it is what screenshots and exported graphics save as. Two things about it behave differently from a photo, and both catch people out.
- Transparency has to become something. PDF pages are not transparent, so the see-through parts of a PNG take on the page background colour — white unless you change it. For a screenshot that is exactly right. For a logo meant to sit on a coloured background, set the background colour to match before exporting, or you will get a white rectangle around your artwork.
- Pixel dimensions decide sharpness, not the format. The image is placed at its own resolution, so a 600-pixel-wide screenshot stretched across an A4 page looks soft no matter which tool converts it. To fill a portrait A4 page at 300 DPI print quality you want roughly 2480 × 3508 pixels. If the result looks fuzzy, the answer is a bigger source image.
- Use PNG for the right things. Screenshots, diagrams, logos, and anything with text or sharp edges stay crisp in PNG because it is lossless. Photographs should stay as JPG — saving a photo as PNG multiplies the file size without improving how it looks, and can push you past the 10 MB per-image limit for nothing.
A PNG and a PDF are different kinds of thing, which is the underlying reason for the conversion. A PNG is one picture with no notion of pages. A PDF is a document: fixed page size, multiple pages, predictable printing. Wrapping the image in a page is what makes it acceptable where a document is expected — and if you need to combine several of those documents afterwards, use Merge PDF.
The settings that matter
Page layout controls, and what each one changes
Page size — A4 or Letter
Pick the one your printer or upload form expects. A4 is standard nearly everywhere; Letter is standard in the US and Canada.
Orientation — portrait, landscape, or automatic
Automatic gives each page the orientation that matches its own image, so a mixed batch of photos does not end up with landscape shots letterboxed onto portrait pages.
Fit — contain or cover
Contain shows the whole image and leaves space where the shapes differ. Cover fills the page completely and crops the overflow. Use contain for documents where nothing may be cut off.
Margin — 0 to 80 px
The white border around each image. Set it to zero for edge-to-edge pages, or leave a margin for anything that will be printed and held.
Background colour
What sits behind the image — and what shows through the transparent parts of a PNG. White by default; change it so a transparent logo does not land in a white box.
Converting images to PDF, answered
Upload your images, drag them into the order you want, choose the page size and layout, and export. The result is one PDF with each image on its own page. You can add up to 30 images in a single conversion, each up to 10 MB, with no signup and no watermark on the output.
JPG (JPEG), PNG, and WEBP. Other formats — including BMP, GIF, TIFF, HEIC, and AVIF — are not accepted and will be rejected on upload. If you have one of those, convert it to PNG or JPG first: on Windows, open it in Paint and use Save As; on a Mac, open it in Preview and use File then Export. iPhone photos saved as HEIC can be converted by changing Settings, Camera, Formats to "Most Compatible", which makes the camera save JPG instead.
Transparent areas are filled with the page background colour, because PDF pages are not transparent — something has to be behind the image. By default that is white, which is what you want for a screenshot or a scanned document. If your PNG is a logo or graphic designed to sit on a coloured background, set the page background colour before exporting so the transparent areas match instead of turning into a white box around your artwork.
A PNG is a single image — one picture, one file, no concept of pages. A PDF is a document container: it can hold many pages, keeps a fixed page size so it prints predictably, and can carry text, fonts, and links alongside images. That difference is why upload forms almost always ask for a PDF rather than a photo. Converting a PNG to PDF does not add anything to the picture; it wraps it in a page so it can be paginated, printed at a known size, and accepted where a document is expected.
The image is placed on the page at its own resolution, so nothing is deliberately downscaled. What actually determines how good it looks is the relationship between the image and the page: a photo that is 3000 pixels wide fills an A4 page at print quality, while a 600-pixel-wide screenshot stretched across the same page will look soft, because there are not enough pixels to cover it. As a rule of thumb, aim for around 2480 × 3508 pixels to fill a portrait A4 page at 300 DPI print quality. If a small image looks soft, the fix is a larger source image, not a different converter.
It depends on what the image is. Use PNG for screenshots, diagrams, logos, and anything with text or sharp edges — it is lossless, so lines and small type stay crisp. Use JPG for photographs, where lossless compression buys you nothing visible and costs a great deal of file size. Converting a photo to PNG first is a common mistake: it makes the file several times larger without making the picture any better, and it can push you over the upload limit for no benefit.
No — each image gets its own page. If you need several pictures arranged on a single page, build that page in the PDF creator instead, where you can place and size images freely, then add the result to your document.
Yes. Before you export you can drag images into a different order, rotate any of them in 90-degree steps, duplicate one, and remove any you do not want. The final PDF follows exactly the sequence shown on screen.
You choose A4 or Letter, and portrait, landscape, or automatic. Automatic is the useful default for a mixed batch: each page takes the orientation that matches its image, so a landscape photo gets a landscape page and a portrait one gets a portrait page, and nothing is rotated or letterboxed unnecessarily.
That is the page margin, and it is adjustable — set it to zero for edge-to-edge images. There is also a fit setting that changes how the image relates to the page: "contain" shows the whole image and leaves space where the image and page shapes differ, while "cover" fills the page completely by cropping the overflowing edges. Use contain for documents and receipts where nothing may be cut off, and cover for photos where filling the page matters more than the edges.
Up to 30 images in a single PDF, with each image up to 10 MB. For a longer set, convert in batches and combine the resulting PDFs with Merge PDF.
It is free with no signup and no watermark. Your images are uploaded over an encrypted connection, used only to build the PDF, and removed after your session ends — they are not stored long-term, sold, or shared. Conversion happens on our server rather than in your browser, so an internet connection is required.
