Need to turn a stack of photos into a single PDF document, or extract pages from a PDF as individual images? Rekreay's free Image ↔ PDF Converter does both — entirely inside your browser, with zero uploads and zero cost. You can combine multiple JPG, PNG, or WebP images into a single PDF in seconds, or drop in any PDF and download every page as a high-quality image. Your files never leave your device, so everything stays completely private.
Unlike desktop software that requires installation, or online services that upload your documents to remote servers, this tool runs entirely in JavaScript using two trusted open-source libraries: jsPDF for building PDF files and Mozilla PDF.js for reading them. Choose your paper size, decide whether to fit or fill each page, set your output image quality — then convert and download instantly. Whether you are archiving photos, preparing a document to send by email, or extracting slides from a PDF presentation, this tool handles it all for free.

What Is This Image ↔ PDF Converter?
The Rekreay Image ↔ PDF Converter is a free, browser-based tool that works in both directions: combine multiple images into a single PDF document, or extract every page of a PDF as a separate image file. Everything runs locally inside your browser using jsPDF (for building PDFs) and Mozilla PDF.js (for reading them), so your files never leave your device.
Converting images to PDF is essential whenever you need to send a collection of photos as a single document — scanned forms, ID documents, project portfolios, or photo reports. You can add multiple JPG, PNG, or WebP images, drag to reorder them, choose the page size (A4, Letter, A3, or fit to image), toggle margins, and pick portrait or landscape orientation. Each image becomes one page of the resulting PDF, ready to email or print.
Converting a PDF to images is equally useful: extract specific pages for sharing on social media, convert a PDF report into editable image files for a presentation, or simply preview pages without opening a PDF viewer. You can choose JPG or PNG output and control the quality level. Both conversion modes are available without installing any software, creating an account, or paying anything.
How to Use the Image ↔ PDF Converter
-
1Choose your conversion direction. Click "Images → PDF" to combine one or more images into a single PDF document, or click "PDF → Images" to extract each page of a PDF as a separate image file. The tool switches modes instantly.
-
2Upload your file or files. Drag and drop images (JPG, PNG, WebP) or a PDF file onto the drop zone, or click "Choose Images" / "Choose PDF". When converting images to PDF you can add multiple images at once — each becomes a separate page. Drag to reorder them using the list before converting.
-
3Adjust your settings. For Images → PDF: choose a page size (A4, Letter, A3, or fit to image), pick portrait or landscape orientation, and toggle margins on or off. For PDF → Images: choose JPG or PNG output and set your quality level.
-
4Click Convert. The tool processes your files entirely in your browser using jsPDF (for building PDFs) and Mozilla PDF.js (for reading them). A progress bar tracks each page. Nothing is sent to any server at any point.
-
5Download your result. For a PDF output, click "Download PDF" to save a single file. For image outputs, click "Download All Images" to save every page at once, or click the individual download button under each page preview to save specific pages one at a time.

Frequently Asked Questions
Tips & Best Practices for Image ↔ PDF Conversion
-
💡Compress images before combining them into a PDF. Large images produce large PDFs. Before converting, run your images through the Image Compressor to reduce their file sizes without visible quality loss. A PDF built from compressed WebP images at 80% quality can be 70–90% smaller than one built from uncompressed originals — much easier to email or share online.
-
💡Choose "Fit to image" page size for photo books and portfolios. If your images are all a consistent size (e.g., landscape photos from a single camera), "Fit to image" creates a PDF where every page is exactly the same dimensions as the image — no borders, no white margins. This looks clean and professional for portfolios, photo galleries, and image-heavy documents.
-
💡Use A4 or Letter for documents and forms. If your PDF is intended for printing or sharing as a formal document — invoices, reports, completed forms, or ID scans — choose A4 (used in most countries) or Letter (used in the US and Canada). These standard sizes ensure the document prints correctly on standard office paper without scaling or cropping.
-
💡Use PNG output when extracting PDF pages for editing. PNG is lossless — every pixel from the PDF page is preserved exactly in the output image. If you plan to further edit, annotate, or crop the extracted page images, PNG is the better choice. Use JPG only when file size matters more than pixel-perfect accuracy, such as for web thumbnails or quick previews.
-
💡Resize images to a consistent width before combining. If your images come from different sources and have varying widths (e.g., a mix of portrait phone photos and landscape camera shots), the PDF pages will have inconsistent sizes. Use the Image Resizer to standardise your images to a consistent width before adding them to the converter — this produces a more professional, uniform-looking PDF.
-
💡Check page order carefully before converting. The PDF will contain your images in exactly the order they appear in the list at the time you click Convert. Take a moment to confirm the sequence is correct — especially for multi-step documents like instruction manuals, form submissions, or scanned multi-page documents — since reordering after conversion requires starting over.
