Why phone photos often make poor document PDFs
Phone cameras capture images at very high resolution — which is great for photos, but creates problems for documents:
- File sizes can be 3–8 MB per page
- Images may be rotated or perspective-distorted
- Background, shadows, and uneven lighting reduce readability
- Colors may be inconsistent page to page
A few simple steps fix most of these issues before you create the PDF.
Step 1 — Capture with document mode
Most modern phone camera apps include a document scanning mode (sometimes called "Doc Scan" or similar). This automatically:
- Corrects perspective distortion
- Crops to the document edges
- Enhances contrast for better readability
If your camera app does not have this, take the photo from directly above, in good diffuse light, with the document on a flat surface.
Step 2 — Compress images if needed
If your photos are 5+ MB each, use Compress Image to reduce file size before creating the PDF.
Use a quality setting of 85–90% for documents with text. This significantly reduces file size while keeping text sharp. Avoid going below 70% — it will visibly blur fine characters.
Step 3 — Convert to PDF
Open Image to PDF and add your images:
- Arrange pages in the correct reading order
- Select A4 or Letter page size for standard document formatting
- Use "Fit to Image" only if you want to preserve the exact image dimensions
Click Create PDF and download the result.
Step 4 — Add searchable text (optional)
If the document contains typed text you want to be able to search or copy, run Basic OCR on the PDF after converting.
This works best on clearly printed text. Handwritten notes will not convert reliably.
Step 5 — Combine with other documents (optional)
If this is one section of a larger document, use Merge PDF to combine it with other PDFs in the correct order.
Practical examples
Receipts and invoices: Photograph each document, compress to ~200 KB per image, convert to PDF as a batch, submit or file.
Application supporting documents: Photograph IDs, certificates, and forms — convert to one well-ordered PDF per category.
Handwritten notes: Convert to PDF for archiving. For typed sections, run OCR to make them searchable.
Common questions
Will PNG transparency be preserved in the PDF?
Not with the current tool. Images are encoded as JPEG in the PDF, so transparent areas will appear with a white background.
How many images can I add at once?
There is no hard limit in the interface, but very large batches may slow down on older devices.
Does the page order matter before converting?
Yes. Arrange images in the exact reading order you want before clicking Create PDF — reordering after is possible but adds a step.
Can I make the PDF searchable after conversion?
Yes — run Basic OCR on the converted PDF to extract text from clearly typed pages.
