Common Use Cases
Converting Aadhaar Card Scan to PDF
Many government portals require your Aadhaar as a PDF. Take a photo of both sides, upload both images, and convert to PDF. Use Compress PDF afterward if the portal has a file size limit.
Creating a Photo Album PDF
Upload 20–30 photos in order, choose Fit to Image page size, and convert. Each photo becomes a full-bleed page in the PDF � great for sharing memories or presentations.
Combining Scanned Pages
If you photographed a multi-page document one page at a time, upload all photos, drag them into order, and convert. The result is a clean, single multi-page PDF.
Converting WhatsApp Images to PDF
Save the images from WhatsApp to your photo gallery, upload them to PDFworld, and convert. Works on both iPhone and Android without any app needed.
Submitting Multiple Documents Together
For college applications or loan submissions that need multiple document images bundled together � upload all images at once and convert to a single PDF.
Troubleshooting
The PDF file is very large � Use Compress PDF after conversion to reduce the file size for email or portal uploads.
HEIC images are not uploading � Ensure you are using an updated browser (Chrome 90+ or Safari 14+). Alternatively, convert the HEIC to JPG first on your iPhone via Settings > Camera > Format > Most Compatible.
The image order is wrong � Drag the thumbnail cards into the correct order before clicking Convert.
Image quality looks reduced � By default, images are embedded at full resolution. If you applied Maximum compression afterward, try Balanced compression instead.
