About this tool

Break a bulky PDF into several smaller files, each capped at a maximum size you define in KB, MB, or GB. The tool studies the document and chooses sensible break points so every piece lands within the ceiling you set, which makes it a natural fit for email clients that reject large attachments, cloud platforms with upload caps, or any workflow demanding files of a certain weight. You stay in charge of those thresholds, dialing them up or down to suit the destination. Each chunk that comes out retains the original's formatting, imagery, and crisp text without any degradation. All of this work takes place right inside your browser, so the source document never travels off your device on its way to being divided. Grab the resulting pieces one at a time or bundle them into a single ZIP. Ideal for professionals emailing hefty reports, students facing assignment upload limits, or anyone bound by strict size requirements.
