How to Convert Images to PDF

To convert images to PDF, upload your JPG or PNG files, drag the thumbnails into the order you want, choose a page size and orientation, then click Convert to PDF — the PDF downloads to your device instantly, with no upload to any server.

When do you need to convert images to PDF?

Images and PDFs serve different purposes. Images are easy to capture but awkward to share in bulk, print at a specific size, or submit to a system that expects a document file. Converting images to PDF solves a specific set of practical problems:

• Scanning documents with a phone camera — phone cameras produce JPG photos, not PDFs. Converting the photos to a PDF creates a proper document that can be emailed, filed, or submitted to a bank, government office, or employer
• Combining multiple images into one file — a multi-page document scanned or photographed one page at a time produces multiple image files. Converting them all into a single PDF creates one coherent document rather than a folder of numbered photos
• Submitting scanned forms or contracts — most document submission systems expect PDF, not image files. Converting before submission avoids rejection or the recipient having to convert it themselves
• Sharing a photo set in a printable format — a PDF preserves the intended layout and page size in a way that a collection of JPGs does not, making it easier for the recipient to print or review in order
• Creating portfolios or presentation handouts — image files converted to a single PDF are easier to distribute and review than a ZIP of photos
• Archiving receipts and invoices — photos of paper receipts converted to PDF are easier to organise, search, and submit for expense claims than folders of image files

The problem with most online conversion tools

The photos most commonly converted to PDF — scanned passports, driving licences, payslips, bank statements, signed contracts, medical forms — are among the most sensitive files on a person's device. Yet converting with the major online tools means uploading those files to iLovePDF, Smallpdf, or Adobe's servers before anything happens.

Your scan of a bank statement travels to a third-party server, sits in a queue, gets processed, and comes back. The service's privacy policy may say it deletes files after an hour, but you have no visibility into what actually happens in that time: whether the file is logged, indexed, or stored in a way that persists beyond the stated retention window.

FixMyPDF converts images to PDF entirely in JavaScript using pdf-lib in your browser. Each image is read from your device, drawn into a new PDF page, and the resulting file is generated locally. No file is transmitted. A scanned passport or bank statement never leaves your device during the conversion.

How to convert images to PDF step by step

1. 1
   Open the Image to PDF tool
   Go to fixmypdf.tech/tools/image-to-pdf.html. No sign-up or software required.
2. 2
   Upload your images
   Drag one or more JPG or PNG files onto the drop zone, or click to browse. You can select multiple files at once. Each image appears as a thumbnail in the preview grid.
3. 3
   Arrange the page order
   Drag any thumbnail to reposition it. The panel is labelled Images — drag to reorder. Click the × on any thumbnail to remove an image from the set. Use the Add more images button to append additional files without starting over.
4. 4
   Choose page size and orientation
   Select a page size (A4, Letter, or Original image size) and an orientation (Auto, Always Portrait, or Always Landscape).
5. 5
   Click Convert to PDF and download
   Press the Convert to PDF button. Each image is placed on its own page in the order you arranged, and the PDF downloads to your device. Your original image files are not modified.

JPG vs PNG: does it matter which format you use?

Both formats are supported. The choice affects the quality and size of the resulting PDF but not the conversion process itself.

For scanned photographs, JPG is the better source format because the existing lossy compression has already reduced the file size without visible degradation at normal viewing distances. For scanned text documents, receipts, or forms — where sharp edges and legible text matter more than continuous tone colour — PNG produces a higher-quality result in the PDF.

If your images are phone camera photos of documents (the most common case), they will typically be JPG already. The tool embeds them at their original quality; no additional quality loss is introduced during conversion.

Choosing page size and orientation

The page size and orientation settings control how each image is placed on its PDF page. These settings matter most when you intend to print the PDF or submit it to a system with specific page-size requirements.

Page size

Orientation

The default Auto (match image) setting examines each image's aspect ratio and places it on a portrait page if the image is taller than it is wide, or a landscape page if it is wider than it is tall. This is the right choice for mixed-orientation image sets where each image should be displayed at its natural orientation.

Always Portrait forces every page to be portrait regardless of the image's aspect ratio. Landscape images will be scaled down and letterboxed. Use this when the recipient expects a portrait document and some of your images happen to be landscape.

Always Landscape forces every page to landscape. Use this when all your images are wide-format, such as spreadsheet screenshots or panoramic scans.

Tips for common image-to-PDF scenarios

Scanning a multi-page document with your phone

Photograph each page in order, then upload all the photos at once using the multi-file selector. The thumbnails will appear in upload order — if your phone numbers them sequentially, they will typically be in the right order already. Drag any out-of-order thumbnails into position before converting. Use A4 or Letter page size depending on the document's origin.

Getting the right orientation for phone photos

Phone cameras sometimes embed incorrect EXIF rotation metadata, causing photos to appear sideways when opened on a desktop. If your converted PDF has sideways pages, use the Rotate PDF tool to correct the orientation after converting. Alternatively, open the photos in your phone's photo editor, manually rotate and save, then re-upload the corrected images.

Creating a PDF from screenshots

Screenshots are typically PNG format. Select Original image size for the page size when converting screenshots — this preserves their exact pixel dimensions, which is important for readability if the screenshots contain small text. A4 or Letter scaling can make fine UI details hard to read.

Reducing the size of the resulting PDF

High-resolution phone photos can produce large PDFs. After converting, run the result through the Compress PDF tool. The compressor re-encodes the embedded images at a lower quality, which often halves the file size with no visible difference when reading the document on screen.

Adding a watermark after converting

If you need to mark the resulting PDF as CONFIDENTIAL, DRAFT, or SAMPLE, convert the images first, then open the PDF in the Add Watermark tool. The watermark is applied to every page in a single operation.
