π‘ For crisp text and sharp details, use images at least 1240Γ1754 px (equivalent to A4 at 150 DPI) or larger. Upscaling small images will appear blurry in the PDF.
PDF is the universal format for documents that need to look exactly the same on every device. When you convert a photo or scan to PDF, you package it in a container that preserves dimensions, embeds fonts if any are present, and opens correctly in every operating system and mail client without needing a specific image viewer. This is why most official forms, contracts, and submission portals request PDF rather than raw image files.
Common scenarios where you need an image as a PDF: submitting a scanned document to a government portal, attaching a signed form to an email, combining a series of photos (travel receipts, medical records, handwritten notes) into a single file, or preparing a photo portfolio in a printable format. Converting images to PDF also protects the content β PDF files cannot be as easily edited as image files, which matters for documents with signatures or stamps.
When combining multiple images into one PDF, each image becomes a separate page in the document. This is far more practical than sending ten separate JPEG files β the recipient gets a single, organized document with consistent page dimensions that prints cleanly. The tool supports dragging images into the order you want before generating the PDF, so you can control the page sequence.
A PDF page is defined in millimeters or points, while your images are measured in pixels. The relationship between them depends on how large you want the image to appear on the page. An image embedded in a PDF at A4 size (210Γ297 mm) at screen resolution (72 DPI equivalent) needs to be at least 595Γ842 pixels to fill the page without upscaling. For print-quality output at 150 DPI, you need 1240Γ1754 pixels; at 300 DPI (professional print), you need 2480Γ3508 pixels.
The "Fit" mode (default) scales the image down to fit within the page margins while preserving its aspect ratio. This is the safest option β it never crops content and always shows the full image centered on the page. "Fill page" scales the image to cover the entire page, which may crop the edges of images whose aspect ratio does not match the page. "Stretch" fills the page completely, distorting the image if its proportions differ from the page β generally only suitable for photos that closely match the page aspect ratio.
| Page size | Dimensions | Min px (150 DPI) | Min px (300 DPI) |
|---|---|---|---|
| A4 | 210Γ297 mm | 1240Γ1754 px | 2480Γ3508 px |
| Letter | 216Γ279 mm | 1275Γ1650 px | 2550Γ3300 px |
| A3 | 297Γ420 mm | 1754Γ2480 px | 3508Γ4960 px |
| A5 | 148Γ210 mm | 874Γ1240 px | 1748Γ2480 px |
Can I convert multiple images into a single PDF?
Yes β add as many images as you need. Each image becomes one page of the final PDF. Use the list's drag handles to set the exact page order before clicking "Create PDF". There is no limit on the number of images, though very large batches (50+ high-resolution photos) may take a moment to process depending on your device.
Are my images uploaded to a server?
No. The PDF is generated entirely in your browser using the open-source jsPDF library. Your images are read by the browser's FileReader API and processed in memory β nothing is sent over the network. You can disconnect from the internet after the page loads and the converter still works.
Why does my PDF look blurry?
Blurriness in PDF output is caused by source images that are too small for the chosen page size. An A4 PDF at 150 DPI requires source images of at least 1240Γ1754 pixels. If your source image is smaller (for example, 600Γ800 pixels), the PDF converter has to upscale it, which produces a blurry result. Use the Image Resizer to check dimensions, or use higher-resolution source images.
What page size should I use?
Use A4 if your audience is primarily in Europe, Asia, or most of the world. Use Letter (8.5"Γ11") if your audience is in the United States or Canada. Both are universally accepted by email clients and office printers. A3 is a larger format for posters or detailed diagrams. A5 is half the size of A4, useful for booklet-style documents or smaller flyers.
What image formats are supported?
JPG, PNG, WebP, and any other format your browser can display (BMP, GIF, AVIF on supported browsers). All images are internally converted to JPEG before embedding in the PDF, which produces compact file sizes. Transparent PNG areas are filled with white β PDF does not support image transparency at the page level.
Can I set the PDF to landscape orientation?
Yes β select "Landscape" in the Orientation dropdown. All pages in the PDF will use the same orientation. If your images have mixed orientations (some portrait, some landscape), the Landscape setting works best for horizontal images. For mixed batches, portrait is usually the better default since it accommodates both orientations with less wasted white space.
