Image to PDF Converter

Turning images into a PDF is one of the most common everyday document tasks. A teacher scans worksheets with a phone and needs to send them as one file; a freelancer photographs receipts and wants a single attachment for an expense claim; a student combines diagram screenshots into one handout. Loose image files are awkward to share, easy to lose track of, and print inconsistently. A PDF solves all of that: it bundles your pictures into one ordered document that opens the same on every device and prints cleanly. This guide shows how to convert and combine images into a PDF, free and right in your browser.

How to convert images to PDF

1. Add your images. Drag and drop them onto the tool, paste from the clipboard, or click Choose images. You can add one image or hundreds, and mix formats freely.
2. Put the pages in order. Drag the thumbnails, or use the up/down arrows. The page numbers update live so you always see the final sequence. Remove any page with the X button.
3. Choose the page layout. Pick A4, Letter, or Fit to image, then set the margin, the fit mode, and the page background if you want.
4. Download your PDF. One combined document downloads straight to your device, ready to print, email, or upload.

The whole document is assembled in your browser, so your images are processed on your own device and the build is near-instant for typical batches.

Which image formats work

• JPG (JPEG) — the most common photo format. Camera photos, scans and downloads are usually JPG. These are embedded straight into the PDF with no re-compression.
• PNG — lossless screenshots, graphics, and images with transparency. Also embedded directly; transparent areas are flattened onto the page background.
• HEIC — the format iPhones use by default. It’s decoded in the browser and placed into the PDF, so you don’t have to convert your photos first.
• WebP — the modern web format many sites and apps now save. Converted automatically before it’s placed.
• GIF — simple web graphics; the still frame is used.
• BMP — uncompressed Windows bitmaps, converted on the way in.

Page size, orientation and fit

The two decisions that shape your PDF the most are the page size and the fit mode.

• A4 / Letter give you a standard printable page. A4 (210 × 297 mm) is the global default; Letter (8.5 × 11 in) is standard in the US and Canada. Pick the one your printer or recipient expects.
• Fit to image makes each page exactly the size of its picture, with no borders or letterboxing. This is ideal for screenshots, artwork, or anything you’ll only ever view on screen.

Orientation can be Auto (each page follows its image — wide photos go landscape, tall ones portrait), or you can force Portrait or Landscape for a uniform document.

Fit mode controls how an image sits inside a fixed page:

• Fit (contain) shows the whole image, adding even margins where the aspect ratios differ. This is the safe default — nothing is ever cropped.
• Fill (cover) scales the image to cover the entire page, cropping the overflow. Great for full-bleed photo pages.
• Actual size places the image at its native dimensions and only shrinks it if it would overflow — useful when print size matters.

Keeping quality high (and file size sensible)

JPG and PNG pages are written into the PDF using their original pixels, so there’s no second round of compression and no visible quality loss. For other formats, images are converted at high quality, and extremely large pictures are scaled to a reasonable page resolution. That keeps the resulting PDF light enough to email while still looking crisp at normal viewing and print sizes.

A few practical tips:

• Start from the best source you have. A PDF can’t recover detail that a heavily compressed image already lost.
• For text-heavy scans, use the highest-resolution capture your phone or scanner offers, so small print stays legible.
• Lots of huge photos make a big PDF. If you need to email a large batch, compress the images first, or build the PDF and then compress the PDF.

Combining vs separate files

Most people want one PDF — every image as a page in a single document. That’s the default here. But sometimes you’d rather keep them separate (for example, one PDF per receipt). For that, switch on Save a separate PDF per image, and the tool builds an individual single-page PDF for each image and bundles them into one zip download. You get the convenience of a single download without merging the pages.

Common uses

• Receipts and invoices into one expense-claim attachment.
• Scanned documents or forms photographed with a phone, sent as a single file.
• ID, passport or visa pages combined for an application upload.
• Screenshots of a conversation, error, or report turned into a tidy handout.
• Photo sets and portfolios delivered as one easy-to-open document.

However you use it, the conversion happens on your device and the finished PDF is yours to download — no account, no watermark, and no limit on how many you make.
