JPG to PDF: turning photos and scans into one clean document
Mostly used for phone-camera document scans. Here is how to stop them coming out crooked, huge and unreadable.
The overwhelmingly common use for this is photographing documents with a phone and needing them as a single PDF, because almost every official portal in India accepts PDF and rejects a folder of JPGs.
The conversion itself is trivial. The quality of the result is almost entirely decided before you convert, by how you took the photos. Flat, evenly lit, shot straight on, and cropped to the page edges beats any amount of post-processing. The converter is in the ToolHub PDF section, and it lets you set page size and order rather than assuming.
JPG to PDF: the facts that matter
| Input formats | JPG, PNG, and common image types |
| Page size | A4 recommended, or fit-to-image |
| Order | Manual, set before export |
| Typical output size | Driven almost entirely by your source photos |
| Multi-page | Yes, one image per page |
How to do it, step by step
- 1Crop each image to the document edges before you start. This alone fixes most complaints about the output.
- 2Open the JPG to PDF tool in ToolHub and add all images at once.
- 3Set the order. The tool follows your arrangement, not the filename order.
- 4Choose A4 page size unless you have a specific reason not to. Portals expect it.
- 5Export, then check the file size against whatever limit you need to meet.
Three things worth knowing
- Compress the images first, then build the PDF. This order gives a smaller file at better quality.
- Natural light near a window beats flash for document photos, every time.
- Check the portal size limit before you start, not after three failed uploads.

Compress Image
Most images can lose 60 to 70 percent of their size with no visible difference. Here is where the line actually is.

Compression targets images, not text. That one fact explains why some PDFs shrink 90 percent and others barely move.

Combine several PDFs into one, control the page order, and avoid the two mistakes that produce a broken output file.
