Why use a PDF instead of photos
A phone makes it easy to photograph a certificate, an ID card or a signed letter. But a pile of loose image files is awkward to send. They can arrive in the wrong order, they show up at different sizes, and many forms only accept PDF. A single PDF keeps the pages together in order and looks the same on every device.
Take better photos first
The PDF can only be as clear as the photos you put in. A few habits make a big difference.
- Use good light. Daylight from a window works well. Avoid your own shadow falling on the page.
- Hold the phone straight above the page. Shooting at an angle makes the edges slanted and the text harder to read.
- Put the page on a plain, flat surface. A dark table behind a white page makes the edges easy to see.
- Fill the frame, but do not cut off the edges. The whole document should be visible.
- Check that the text is sharp. Zoom in on the photo. If you cannot read a line, take it again.
If there is too much empty space around the page, use Crop Image to cut it away before you continue.
How to make the PDF with Velfile
- Open JPG to PDF and choose your images. JPG, PNG and WebP all work. You can add up to 30 images at a time, each up to 100 MB.
- Use the up and down controls to set the page order. The first image becomes page one.
- Pick the Page size and the Margin.
- Press Create PDF, then Download PDF.
Choosing the page size and margin
- A4 is the standard paper size in most countries, including Indonesia. Choose it when the PDF might be printed or when a form asks for A4.
- Letter is the standard in the United States and Canada.
- Fit to image makes each page the same shape as its picture. It is good for photos and screenshots, because nothing is cut or padded with white space.
The margin is the empty border around the picture. None fills the whole page, while Small and Medium leave some white space, which looks neater if the PDF will be printed.
Keep the file size under control
Photos from a modern phone are large, and 30 of them in one PDF can become very heavy. If the result is too big to send, you have two options. You can shrink each photo first with Compress Image and then make the PDF. Or you can make the PDF first and then run it through Compress PDF. Shrinking the photos first usually gives you more control over the quality.
When you already have some PDFs
If part of your documents are already PDFs and the rest are photos, make a PDF from the photos first, then join everything with Merge PDF.
