Supports JPG, PNG, GIF, WebP, BMP formats
This Image to PDF converter is straightforward and intuitive. Here is a step-by-step guide:
Upload Images: Click the upload area or drag images directly into the dashed box to select local image files. The tool supports common formats including JPG, PNG, GIF, WebP, and BMP. You can select multiple images at once for batch conversion. Uploaded images appear as a thumbnail list so you can preview each one clearly.
Reorder Images: Each image in the list has a drag handle on the left. Hold the handle and drag to change the order. This order determines the page sequence in the final PDF. To remove an image, click the delete button on the right.
Configure Page Settings: In the settings area, choose the PDF page size (A4, Letter, A3, A5), orientation (portrait or landscape), image fitting mode, and margin size. Fit Page preserves the aspect ratio while maximizing the image within the page. Fill Page stretches the image to completely cover the page, which may crop edges. Original Size keeps the image at its native resolution without scaling.
Generate and Download: After configuring, click the Generate PDF button. The tool converts everything locally in your browser and automatically downloads the PDF file. No data is ever uploaded to a server, fully protecting your privacy.
Converting images to PDF is useful across many everyday and professional scenarios:
Document Archiving: Organize scanned documents, receipts, and contract photos into a unified PDF for storage and retrieval. Compared to scattered image files, PDF format is better suited for long-term preservation and less prone to accidental deletion or loss.
Portfolio Creation: Designers and photographers can arrange work images in sequence to produce a polished PDF portfolio. By adjusting page size and margins, you can create professional presentation documents to share with clients or use in interviews.
Teaching Materials: Teachers can combine lecture screenshots, exercise images, and answer keys into a single PDF for students to download and print. The uniform PDF format ensures consistent layout across all devices.
Identity Document Backup: Combine photos of ID cards, driver's licenses, and business licenses into one PDF for quick submission when needed. PDF is more compatible with government systems and websites, and typically has a smaller file size.
About the PDF Format: PDF (Portable Document Format) was developed by Adobe. Its greatest strength is cross-platform consistency: no matter which computer or phone opens it, the layout, fonts, and colors remain identical. PDF supports vector graphics, bitmap images, text, and interactive elements, making it the most widely used document exchange format today.
Image Resolution and PDF Quality: When converting images to PDF, the original image resolution directly affects the clarity of the final document. Screen display typically requires 72–150 DPI, while printing needs 300 DPI or higher. If your image resolution is low, choosing Original Size will not make it sharper. We recommend capturing or scanning at the highest available resolution.
PDF/A Archival Standard: For documents that need to be preserved for decades, consider the PDF/A standard. PDF/A is an archival variant of PDF that prohibits features that could hinder long-term readability, such as JavaScript and external links, ensuring documents can still be opened correctly decades from now. The PDFs generated by this tool follow standard PDF specifications and meet archival needs in most situations.
No. This tool processes everything locally in your browser. Images are never uploaded to any server. All conversion happens on your device, ensuring complete privacy and security.
JPEG, PNG, GIF, WebP, and BMP formats are all supported. The tool automatically detects the image format and handles the conversion accordingly.
There is no hard limit, but we recommend converting no more than 50 images at a time for optimal browser performance. Each image becomes one page in the PDF, or you can fit multiple images per page.
The tool embeds images at their original resolution for maximum quality. You can choose from three fitting modes: Fit Page (preserves aspect ratio), Fill Page (may crop), or Original Size, to get the best output for your needs.
Yes. The tool supports A4, Letter, A3, and A5 page sizes, with both portrait and landscape orientations. You can also set custom margin sizes to suit your layout requirements.
No. The PDFs produced by this tool are completely clean, with no watermarks or branding. You can use them for formal purposes with confidence.
If you select Fill Page mode, images will be stretched or cropped to completely cover the page. If the image aspect ratio does not match the page, parts of the image may be cropped. We recommend using Fit Page mode, or changing the page orientation to match the image proportions.
Yes. The tool uses responsive design and works well on phones and tablets. However, due to mobile device processing power and memory constraints, we recommend converting no more than 20 images at a time on mobile.
