How to Scan Court Documents With Your Phone

You don't need a flatbed scanner or Adobe Acrobat to prepare court filings. Your phone camera, a free app, and a flat surface are enough to produce documents that federal courts accept through CM/ECF. Here's how to do it right.

Is a Phone Scan Really Acceptable for Court?

Yes. Federal courts accept PDFs created from phone scans as long as the result is legible and meets basic formatting requirements. The PACER help documentation recommends 300 DPI resolution and black-and-white scanning for text documents. Most modern phone cameras exceed 300 DPI equivalent when scanning letter-size documents from a normal distance. The resulting quality is comparable to what you'd get from a desktop scanner.

What courts care about is the final PDF — not how you created it. A crisp, well-cropped phone scan is better than a blurry, skewed flatbed scan. What matters is legibility, proper page size, and file format compliance.

Free Scanner Apps

For most pro se filers, the built-in scanner (Notes on iPhone, Google Drive on Android) is sufficient. Use Adobe Scan if your court requires text-searchable PDFs, since its free OCR feature handles that automatically.

How to Get a Court-Quality Scan

1. Use a flat, dark surface. Lay the document on a dark table or desk — the contrast helps your phone's edge detection work properly. Don't hold the document in the air or scan on a white surface where the page edges disappear.
2. Use even, natural light. Scan near a window or under overhead lighting. Avoid using your phone's flash — it creates a bright spot in the center and shadows at the edges. If you see glare, angle the document slightly or move to a different light source.
3. Hold your phone parallel to the document. Position your camera directly above the page, not at an angle. Scanner apps can correct minor perspective issues, but starting parallel gives the best results. Keep your hands steady or prop your phone against something.
4. Let the app auto-detect edges. Most scanner apps will highlight the detected document borders before capturing. Make sure all four edges are inside the frame. If the app misses an edge, adjust your position or tap to manually set the crop boundaries.
5. Scan one page at a time. For multi-page documents, scan each page individually in order. The app will add each scan to the same document. Check the page order before exporting.
6. Review before exporting. Scroll through every page. Check for: blurry text (re-scan that page), cut-off edges (re-crop), wrong orientation (rotate), and dark or washed-out contrast (adjust brightness if the app allows it).
7. Export as PDF. Save or share the scan as a PDF file. If you're using the built-in scanner and it only exports images, or if you need more control over page size and layout, drop the images into ecfpdf.org to convert them into a properly formatted court-ready PDF.

Settings That Matter

Resolution

PACER recommends 300 DPI for scanned documents. You don't need to configure this manually with phone scanners — modern phone cameras capture at well above 300 DPI when scanning letter-size pages. If your scanner app has a quality setting, choose "High" or "300 DPI" rather than the maximum setting. Scanning at 600 DPI doubles file size with no visible quality improvement for court documents.

Color mode

Use black and white (or grayscale) for text documents like contracts, letters, printed emails, and typed records. Use color only when it's essential — photographs, highlighted documents, color-coded charts, or documents where color conveys meaning. A single page in color can be 5-10x larger than the same page in black and white. Over a long filing, that difference determines whether you hit your court's file size limit.

Page size

Federal courts expect U.S. Letter size (8.5 × 11 inches). If your scanner app has a page size setting, choose Letter. If it doesn't, ecfpdf.org will format images to Letter size by default when you convert them.

Common Mistakes

Shadows and fingers in frame

The most common problem with phone scans is your own hands or phone casting a shadow on the document. Hold the phone high enough that your hand shadow falls outside the page. If you can't avoid it, try scanning with the phone upside down (camera at the bottom, closer to the document) or use a stack of books to prop the phone above the page.

Blurry text

If text is blurry, your phone either wasn't focused or you moved while capturing. Tap the screen to focus on the text area before the app captures. Hold still for a full second after tapping. If your phone has image stabilization, it helps, but keeping your hands steady matters more.

Warped pages

Bound documents (books, thick packets, stapled papers) create curved pages that scan poorly. If possible, remove staples and scan loose pages flat. For bound documents you can't disassemble, press the page flat with one hand outside the scan area, or scan in two halves and note in your filing that the exhibit was scanned from a bound original.

Missing pages

When scanning multi-page documents, it's easy to accidentally skip a page or scan the same page twice. After scanning, check the total page count against the original document. Number your scanned pages before converting to PDF if the original pages aren't already numbered.

What About Photographs as Evidence?

Scanning is for turning paper documents into digital PDFs. But if your evidence includes photographs — pictures from your phone camera, screenshots of text messages, photos of physical damage, images of locations — those are already digital. You don't need to scan them. Instead, convert them directly to a court-formatted PDF using ecfpdf.org. Drop your photos in, arrange them in the order you want, set the page size to Letter, and generate your exhibit PDF.

For phone photos used as evidence, keep the originals on your device. Courts may ask about image metadata (date, time, location) to authenticate exhibits, and that information lives in the original photo file, not in the converted PDF.

Complete Workflow: Phone to Court Filing

1. Scan or photograph your documents using the methods above.
2. Review every page for quality, completeness, and order.
3. Convert to PDF — use your scanner app's built-in export, or drop images into ecfpdf.org for court-standard formatting.
4. Check the file size against your court's CM/ECF limit. If it's too large, split into multiple PDFs.
5. Verify the PDF opens correctly by viewing it before filing. Check that all pages are present, in order, and legible.
6. File through CM/ECF or deliver to the clerk's office per your court's filing procedures.

Privacy Reminder

Before filing any scanned document, check for information that must be redacted under Federal Rule of Civil Procedure 5.2: full Social Security numbers, full dates of birth, names of minors, and complete financial account numbers. This applies even if the original document contains this information — it's your responsibility to redact before filing. If you're scanning someone else's medical records, financial statements, or government IDs, review every page for protected information.
