Guides, tips & FAQ
Combine photos into one PDF for uploads
Application portals and email workflows often require a single PDF instead of separate JPG files — for example multiple certificate pages or ID scans on one upload field. This converter merges up to 20 JPEG or PNG images into one PDF locally. WebP and GIF are not accepted on upload. Page order follows the sequence you arrange in the tool. Files stay on your device. If the combined PDF exceeds a portal size limit, run it through our PDF compressor or check whether the form expects separate uploads per document.
How to convert JPG and PNG to PDF online
- Add images: Drop or select up to 20 JPEG or PNG files (WebP, GIF, and other formats are not accepted).
- Reorder pages: Use the up and down controls so each photo appears in the order you need in the final PDF — page order matches your list top to bottom.
- Choose page size: A4 Standard fits each image on a standard A4 sheet while keeping aspect ratio (centered, no stretching or cropping). Auto Size creates each PDF page exactly the pixel dimensions of that image — useful for full-resolution scans or odd sizes.
- Convert and download: Click convert, then download the combined PDF. Everything runs locally in your browser.
A4 vs Auto page size
- A4 Standard: One image per A4 page, scaled to fit inside the sheet while keeping aspect ratio, centered with no stretching or cropping. Best for printing and portals that expect letter/A4 layouts.
- Auto Size: Page width and height match the embedded image. Best when you need native scan resolution without margins.
- Batch limit: Up to 20 JPEG or PNG files per run. For more pages, convert in batches and use Merge PDF.
Note: Original keeps the camera file, so a phone photo can still make a heavy PDF. Balanced and Small shrink the photo before it is embedded. Use Compress PDF after converting if a portal rejects the file size.
