Convert a Single Image Into a PDF
Turns a JPG, PNG, WebP or other common image into a PDF with your choice of page size, orientation and margin. Built with pdf-lib in the browser, so the image is never uploaded.
About the Image to PDF Converter
Sometimes one image needs to be a PDF — a scanned form, a certificate, a single photograph that has to go into a system that only accepts documents. This does exactly that, taking one image and producing a one-page PDF, with enough control over the page to make it look intentional rather than an image dropped onto a sheet.
Three settings shape the page. Size offers A4, US Letter, or Fit to image, which sizes the page to the picture itself. Orientation offers Auto, Portrait or Landscape, with Auto choosing based on whether the image is wider than it is tall. And a margin in points, defaulting to 24, sets the border around the image. The image is scaled to fit within the page and margins and centred, so it is never stretched or cropped.
Key Features
- Common formats accepted: JPG, PNG, WebP and the other formats the browser can decode all convert, so you are not limited to one input type.
- Three page-size modes: A4 and US Letter for a standard sheet, or Fit to image for a page sized exactly to the picture with no border.
- Automatic orientation: Auto compares the image's width and height and picks portrait or landscape to suit, so a landscape photo gets a landscape page.
- Adjustable margin: The 24-point default keeps a tidy border; set it to zero for the image to reach the page edges.
- Image centred, never distorted: The picture is scaled proportionally to fit and centred on the page, so it keeps its shape.
- Made in the browser: pdf-lib assembles the PDF locally, so a scanned certificate or a personal photo is not sent anywhere to become a document.
How to Use the Image to PDF Converter
- Add an image — JPG, PNG, WebP or similar.
- Choose the page size, orientation and margin, or use Fit to image for a borderless page sized to the picture.
- Press Create PDF.
- Download the document.
How It Works
The image is decoded, re-encoded as JPG at 92 percent quality, and embedded into the page with pdf-lib. That re-encoding is worth knowing about: even a PNG is embedded as JPG, so a crisp screenshot or a graphic with sharp text will pick up slight JPEG softening around its edges, and any transparency is flattened onto the page. For photographs this is invisible; for line art or text-heavy images, a tool that preserves the original encoding would keep them sharper.
With Fit to image selected, the page is created at the image's own pixel dimensions treated as points and the margin is ignored, giving a borderless page that matches the picture exactly. With A4 or Letter, the image is scaled down to fit inside the margins if it is larger than the page, but it is not scaled up — a small image on an A4 page stays its own size, centred, rather than being enlarged to fill the sheet.
The finished file is named quenavo-document.pdf regardless of the source image name, so rename it after downloading if you are keeping several. Although this tool is aimed at a single image, its engine will accept more than one and produce a multi-page document; for a deliberately multi-page result from several images, the multiple-images tool gives you reordering control.
When You Need It
Someone applying for a job is asked to submit a signed declaration as a PDF, and all they have is a photo of the signed sheet taken on their phone. Converting the photo to a PDF meets the requirement without a scanner. The declaration carries their signature and personal details, so producing the PDF on their own device rather than through an upload keeps that information private.
A tenant sending a landlord a photograph of a meter reading needs it as a PDF for the letting agency's system. Converting the single image is quick, and keeping it local means a photo that happens to show the inside of their home is not routed through an external converter.
