Can I control page size?

Yes. A4 at 210 by 297 millimeters and US Letter at 8.5 by 11 inches are the most common presets, with custom dimensions usually available too. The image is then either scaled to fit the page while maintaining aspect ratio or sized to fit the page width with variable height — the right choice depends on whether consistency or original proportions matter more.

What about image quality in PDF?

Most tools offer a quality slider that controls how aggressively images are compressed during PDF generation. Lower settings produce smaller PDFs that are easier to email and share, while higher settings preserve fine detail for print or archival use. A reasonable rule of thumb is 70 percent for sharing and 95 percent for printing.

Can I reorder images?

Yes, almost universally. Most tools accept drag-and-drop reordering, and others sort by filename. Order matters enormously for multi-page documents like contracts or reports, so always verify the sequence before generating the PDF — fixing order after the fact means starting over.

Will text in images be searchable?

Not from basic image-to-PDF conversion. The output is an image-only PDF that has no text layer for search engines or readers to query. To produce a searchable PDF, run the output through an OCR tool afterward, or use a specialized scanner-and-OCR tool that handles both steps in one pass.

How do I handle different image sizes?

You typically have three approaches available — scale everything to a single uniform page size for consistency, preserve each image's original dimensions for maximum fidelity, or fit each image to a uniform width with variable height. Pick the one that best balances polished presentation against preserving the source quality of your images.

Can I add password protection?

Some PDF tools support password protection and permission restrictions like no-editing or no-printing flags. Most free browser-based converters don't include this feature. When you need real document security — sensitive contracts, ID copies, financial records — dedicated PDF software like Adobe Acrobat is a more appropriate choice.

Is the data sent to a server?

Browser-based tools using jsPDF or pdf-lib process everything client-side, so your images never leave the device. Cloud-based services upload your images to their servers for processing. For documents containing anything sensitive — signed contracts, identification, medical records — the browser-based path is the safe one.

About Image to PDF Conversion

Converting images to PDF is essential for creating professional documents from photos, scans, screenshots, and graphics. A PDF combines multiple images into a single, universally compatible document that preserves quality across devices and platforms.

This tool processes all images entirely in your browser using the pdf-lib library. Your photos are never uploaded to any server, making it safe for personal, medical, legal, and business documents that require privacy.

Supported Formats and Features

JPEG / JPG

The most common image format for photos. JPEG files are efficiently embedded in PDFs with no re-encoding, preserving the original quality while keeping file sizes small.

PNG

Perfect for screenshots, graphics, and images with transparent backgrounds. PNG files maintain lossless quality in the output PDF, ideal for text-heavy images and diagrams.

WebP

Google's modern image format offering superior compression. WebP images are automatically converted for PDF compatibility, so you can use images straight from the web.

Batch Upload

Select multiple images at once or add them in batches. There is no limit on the number of images you can combine into a single PDF document.

Drag-and-Drop Reorder

Rearrange images by dragging thumbnails or using the up/down arrows. The order shown is the order pages appear in the final PDF.

Page Size Options

Choose from standard page sizes (A4, Letter, Legal) or enter custom dimensions. Switch between portrait and landscape orientation to match your content.

Fit Modes Explained

Fit Within Page

Scales the image to fit entirely within the printable area while maintaining the aspect ratio. Best for ensuring the entire image is visible with no cropping. White space may appear on sides or top/bottom.

Fill Page

Scales the image to cover the entire printable area. Parts of the image may extend beyond the page boundaries if the aspect ratios differ. Best for creating full-bleed pages.

Actual Size

Places the image at its original pixel dimensions (1 pixel = 1 point). If the image is larger than the page, it is scaled down to fit. Ideal for screenshots and graphics where exact pixel dimensions matter.

Common Use Cases

Scanning Documents

Combine scanned receipts, contracts, or ID documents into a single multi-page PDF for easy sharing and archiving.

Photography Portfolios

Create PDF portfolios from your best photos. PDFs maintain image quality and are easy to share via email or print professionally.

Presentation Slides

Export slide images and combine them into a PDF for offline viewing, printing, or sharing without requiring presentation software.

Insurance & Legal

Compile photos of damage, evidence, or property into a single PDF for insurance claims or legal proceedings. All processing stays local for privacy.

Privacy & Security

100% Client-Side Processing: All image reading, conversion, and PDF generation happens entirely in your browser. No images are uploaded to any server.

No Data Collection: We do not track, log, or store any information about your images or the PDFs you create. Your files remain completely private.

How to Use Image to PDF

Upload images

Drag and drop the images you want combined. Arrange the order through drag-reorder or by relying on filename sorting — whatever fits your workflow.

Configure PDF settings

Pick a page size (A4, US Letter, or a custom dimension), choose orientation, set margins, and decide whether each image scales to fit the page or preserves its original size. Match these settings to where the PDF is going.

Generate PDF

The tool processes your images and produces a multi-page PDF, with one image per page. The whole operation takes only a few seconds for typical batches.

Download PDF

Save the generated PDF for email, archival, or print use. To produce a searchable PDF, run an OCR pass over the output afterward using a separate tool.

When to Use Image to PDF

Document scanning

Receipts, signed contracts, lecture notes scrawled on paper, photos of a whiteboard after a meeting — all of these end up as a pile of images on your phone. Combining them into one PDF turns the mess into a single, organized document you can share with a colleague, archive in cloud storage, or send to your accountant.

Photo albums and portfolios

Photographers, designers, and students often need to deliver a curated set of images as a single file. PDF works as a universal photo album that opens on any device and preserves the order you intended, with no risk of someone scrolling past the cover.

Report generation

Reports filled with charts, dashboards, and screenshots compile naturally into PDF, which preserves layout consistently across operating systems. Stakeholders see exactly what you intended whether they open the file on a Mac, a Windows laptop, or their phone.

Email-friendly multi-image delivery

Attaching twenty separate images to an email looks unprofessional and makes the recipient download each one. Bundling them into a single PDF presents your work cleanly, fits one attachment, and reads as a finished document instead of a folder dump.

Image to PDF Examples

Single image

Input

A 1920 by 1080 photo

Output

A one-page PDF sized to match the image.

The simplest scenario takes one photo and wraps it as a PDF page. Handy when someone insists on a PDF for an upload form even though the source content is a single image.

Multi-page document

Input

Ten photos of a paper contract

Output

A ten-page PDF preserving the page order you specified.

Combining phone photos of a paper document into one PDF mirrors what professional scanners do. Add an OCR pass afterward and you've got a searchable archive of the original.

Mixed dimensions

Input

Photos with varying widths and heights

Output

One image per page, with options for scaling to fit, uniform sizing, or fit-to-width layouts.

When source images don't share dimensions, tools offer choices. Scaling everything to a consistent page size produces a polished look. Preserving original sizes keeps the highest fidelity but yields a less uniform document.

Tips & Best Practices for Image to PDF

1.Reorder your images before generating the PDF. Most converters process in either filename order or drag-drop order, and getting that wrong produces a document that reads in the wrong sequence.
2.Compress large source photos first. A 5MB photo multiplied by fifty images becomes a 250MB PDF that no one can email or download comfortably. A short pre-compression pass keeps output sizes manageable.
3.Pick a page size that matches the destination. A4 dominates internationally, US Letter rules in North America, and custom sizes work best for portfolios and photo books where dimensions follow the imagery.
4.Add OCR afterward if you need a searchable PDF. The basic image-to-PDF output is essentially a stack of pictures; an OCR pass adds an invisible text layer that lets readers and search engines find content inside the document.
5.Use the JPG quality slider when one is offered. Lower settings produce smaller PDFs that are easier to share, while higher settings preserve text legibility and fine detail for archival or print use.
6.Fix rotation, brightness, and contrast in the source photos before conversion. Once the images are wrapped in a PDF, those issues persist and become much harder to correct without going back to the originals.

Frequently Asked Questions

Each image becomes a page in the resulting PDF. The conversion reads each image, scales it to fit the chosen page size, and writes the lot into a single PDF document using a generator like jsPDF or pdf-lib. The output is a standard PDF that opens cleanly in every viewer, supporting common input formats including JPG, PNG, and WebP.
