Splitting large PDFs: portal limits and sensible volume breaks

Some portals reject oversized single files; timeouts and unstable uploads also hit thick packs. Splitting is then not cosmetic; it is a filing requirement. What matters is that references and orientation stay clear for recipients.

Split by content, not only by megabytes

Pure megabyte cuts mid-exhibit confuse. Better along natural boundaries: pleading / schedule / exhibit groups, or chronological sub-volumes. Filenames must carry volume and order (“_part01”, “_part02”), not only “a/b”.

After the split: hold the schedule and citations against the new file boundaries. If A12 suddenly sits in part 2, the schedule must show that or the pleading must change.

Split checklist

• Portal rule: max size and max number of files?
• Choose cut points by content.
• Filenames with part number and matter reference.
• Update schedule and cross-references.
• Spot-check each part for orientation and readability.
• Internally test the whole pack in upload order once.

Technique and quality

Often clean first (empty pages, rotation), then compress, then split - or reverse when parts need different treatment. OCR before splitting can ease text-layer references. LexLogik supports splitting in the processing flow; content volume logic remains the firm’s task.

Split by content, not only megabytes

Cuts mid-exhibit confuse. Prefer pleading, schedule and exhibit groups. Filenames with part number and matter reference. After splitting, hold schedule and citations against new boundaries.

Upload order

Upload parts in intended order and keep receipts. Recompress after splitting only deliberately.

A short overview for recipients cuts queries.

Outward communication

Opponents and courts benefit from a short overview (“Part 1 pleading, Part 2 exhibits A1-A20 …”). That cuts queries and reads as ordered.

Name and receipt part-packs

Number part PDFs (“Pack 1/3”) and keep upload receipts per part. On failure you know what arrived. Avoid identical filenames across matters.

Split on content boundaries

Split at content boundaries (end of schedule, before report, before photo pack), not only at a round page count. Recipients then understand part 2 without losing part 1’s context. Note the cut in the schedule. The pack reads planned - not arbitrarily chopped.

After a split, check that exhibit numbers stay unique across part-packs. Duplicate “Exhibit A1” in pack 1 and pack 2 creates chaos. Global numbering or pack prefixes solve it cleanly.

Tell recipients about part-packs

When filing several parts, give court or opponent a short structure note. That cuts queries and reads as ordered. The note can be one line in the cover letter - it only needs to exist.

Record the decision and responsible person in one line on the matter note. That shortens queries and makes quality transferable across cover. Small notes beat long rework after a failed portal attempt. Matter anchor: content day 24.

Avoid splits mid continuous tables or report chapters. Content boundaries protect readability. One more page in a part-pack beats a cut thought.

Splitting large PDFs is portal logic and reading logic at once: sensible pack boundaries at content breaks, not mid-exhibit. Clear names and receipts per part keep filings traceable. Split is strategy, not emergency chopping.
