Large PDF uploads

Succeed with big PDFs by respecting size limits, splitting binders, and allowing extra processing time.

Overview

Large PDFs are welcome within per-file limits, but they take longer to upload and OCR. Oversized files, unstable networks, and huge image-only scans are the usual failure points.

Why this feature exists

Court binders and disclosure packages are often large — SeraCase should still handle them calmly.

Symptoms

  • Upload stalls near the end
  • File rejected for size
  • Processing takes much longer than smaller files
  • Browser tab becomes unresponsive during upload

Likely causes

  • File exceeds the per-file size limit
  • Very large image-only scan
  • Network interruption mid-transfer
  • Uploading many large PDFs in one batch
  • Corrupt export from the source scanner

Step-by-step

  1. 1

    Check the size limit

    Keep each file within the allowed maximum (typically 50 MB). Compress or split if needed.

  2. 2

    Split oversized binders

    Divide by section (orders, correspondence, financials) into separate PDFs.

  3. 3

    Upload on a stable connection

    Prefer reliable Wi‑Fi or wired networks for multi‑hundred‑page scans.

  4. 4

    Upload large files alone first

    Add the biggest PDF by itself, confirm success, then continue with the rest.

  5. 5

    Give processing time

    Do not re-upload while the job is still running — watch Add Documents status instead.

Best practices

  • Label each split clearly so Evidence stays navigable.
  • Create text-based PDFs when the source system allows.

Productivity tips

  • Export a package after big binders finish processing so you have an offline copy.

Common mistakes

  • Compressing so aggressively that pages become unreadable for OCR.
  • Queuing ten huge scans at once on mobile data.

When to contact support

Contact support if a PDF under the size limit fails repeatedly on a stable network after splitting and single-file retries.

Frequently asked questions

Should I zip my PDFs?

No. Upload supported PDFs directly — zip archives are not an accepted upload type.
