Improve photos before conversion
- Photograph each page on a flat surface with even light and no strong shadows.
- Crop unnecessary background and rotate sideways images before creating the PDF.
- Arrange the files in reading order and remove accidental duplicates.
Create and check the PDF
Select the images in their intended order, start the conversion, and open the automatically downloaded PDF. Zoom in on small text, totals, dates, and signatures. If a page is blurry, replace only that photo and create the PDF again.
Balance image quality and file size
High-resolution photos make text clearer but can produce a large PDF. For email, resize unusually large camera images before conversion or compress the completed PDF once. Always keep an uncompressed copy when the document may be needed as evidence or for official use.
Capture documents consistently
Use the same orientation and similar distance for every photo. Fill the frame with the page while leaving enough edge to avoid cutting off text. A neutral background makes page boundaries easier to recognize, and diffuse light reduces glare on glossy receipts.
Choose an archive strategy
The PDF is convenient for reading, but the original photos may contain more detail. Keep both until the document has been accepted. For important records, use descriptive filenames and store the original images and final PDF together with the date and purpose.
