When to Convert Images to PDF
Common scenarios where image-to-PDF conversion is essential
Scanned Documents
Scanned receipts, invoices, contracts, or identification documents from your phone's camera are typically saved as JPG/PNG. Convert to PDF for professional sharing, archival, tax records, expense reports, or legal submission. PDFs are the standard format for official documents.
Multi-Page Reports
Combine screenshots, diagrams, charts, and photos into a single cohesive PDF report. Perfect for project documentation, research findings, instruction manuals, or presentations where each page is a separate image. One file is easier to share than 20 separate images.
Photo Albums & Portfolios
Create digital photo albums from vacation pictures, event galleries, or professional photography portfolios. PDFs maintain image quality and page order. Easier to email, upload, or print than sending individual image files. Perfect for sharing wedding photos or project portfolios.
Travel & Visa Applications
Visa applications require passport photos, flight itineraries, hotel bookings, bank statements — often as separate images. Combine into one PDF for easier submission. Many visa portals accept PDFs but struggle with multiple separate image files. Reduces confusion and upload errors.
Assignments & Homework
Students often complete assignments on paper, photograph them, and submit online. Convert multiple photos of handwritten work into a single PDF for submission. Keeps pages in order and looks professional. Accepted by most school portals (Canvas, Google Classroom, Blackboard).
Business Proposals
Combine product photos, mockups, pricing sheets, testimonials, and company information into professional proposal PDFs. Clients receive one polished document instead of scattered images. Easy to brand, print, and distribute. Looks more professional than email attachments of loose images.

Image to PDF Best Practices
📸 Image Quality Tips
- Resolution: Use at least 150 DPI for printed PDFs, 72-96 DPI sufficient for screen viewing
- Lighting: Ensure scanned documents have good lighting. Dark photos create unreadable PDFs
- Orientation: Rotate images correctly before conversion. Sideways text is hard to read
- Cropping: Crop unnecessary borders before converting. Cleaner look, smaller file size
- File Size: Compress large images before converting if file size is concern
📑 Organization Tips
- Page Order: Upload images in order or use drag-drop to reorder before conversion
- Naming: Name PDF descriptively: "Expense_Report_March_2024.pdf" not "document.pdf"
- Grouping: Group related images into separate PDFs rather than one giant file
- Cover Pages: Add a title image as first page for professional appearance
- Consistency: Keep all images same orientation for better reading experience
🎯 For Professional Use
- Page Size: Match recipient's country (A4 for international, Letter for US)
- Margins: Add margins if PDF will be printed. Prevents edge cut-off
- Quality: Use high-resolution images for client presentations and portfolios
- Branding: Add watermarks to images before converting if needed for copyright
- File Size: Check final PDF size. Compress if > 25MB for email compatibility

Frequently Asked Questions
Is this image to PDF converter free?
Yes, completely free. No limits on number of images, file size, or conversions. No registration, no hidden fees, no premium features. All processing happens in your browser using free, open-source jsPDF library.
Are my images uploaded to your servers?
No. All conversion happens locally in your browser using JavaScript. Your images never leave your device, are never uploaded, stored, or seen by us. Completely private and secure. Safe for confidential documents, personal photos, or sensitive information.
How many images can I convert at once?
No artificial limit. Practical limit depends on your device's memory. Most computers handle 100+ images easily. Very large batches (200+ high-res images) may take longer but will work. Each image becomes one PDF page in order.
What image formats are supported?
Supported: JPG, JPEG, PNG, WebP, GIF, BMP, TIFF
Output: PDF (single file combining all images)
Most common image formats work. If your format isn't supported, convert it to JPG or PNG first using free tools.
Can I reorder images before converting?
Yes! Upload images in any order, then drag-and-drop to reorder them before creating the PDF. The PDF pages will match your final order. Essential for documents like scanned book pages or sequential reports.
Should I use A4 or Letter size?
A4: Use for international audience, Europe, Asia, Africa, Australia. Standard everywhere except US/Canada.
Letter: Use for US and Canadian recipients. American printers default to Letter.
Fit to Image: Use for digital viewing only (not printing). Preserves exact image dimensions.
Will converting reduce image quality?
No quality loss during conversion. Images are embedded in PDF at their original resolution and quality. However, if you choose page size smaller than image dimensions, images will be scaled down to fit the page, which can reduce apparent quality. Use "Fit to Image" to preserve exact dimensions.
Can I add text to the PDF?
This tool creates image-based PDFs where each page is an image. Text cannot be added during conversion. If you need text, add it to images before converting (using image editors) or use PDF editing software after conversion.
What's the maximum file size?
No artificial limit on input images. Output PDF size depends on image count, resolution, and quality. High-res photos create large PDFs. If final PDF > 25MB, consider compressing images before conversion or use our PDF compressor afterward.
Can I convert screenshots to PDF?
Absolutely! Screenshots are just PNG/JPG images. Perfect for creating documentation, tutorials, bug reports, or instruction manuals. Combine multiple screenshots into one PDF document for easy sharing and reference.
Does it work on mobile devices?
Yes! Works on smartphones and tablets. Take photos with your phone camera, open this tool in mobile browser, and convert images to PDF immediately. Perfect for scanning receipts, documents, or business cards on the go. Slower than desktop for large batches.
What if images have different sizes?
No problem. If you choose A4 or Letter, all images are scaled to fit that page size (maintaining aspect ratio). If you choose "Fit to Image," each page matches its source image size, creating a PDF with variable page sizes. The latter is fine for digital viewing but may cause printing issues.
