사용 방법 Split PDF by Size
Break a large PDF into multiple smaller PDF files, each staying at or below your target megabyte limit.About split PDF by file size
Break a large PDF into multiple smaller PDF files, each staying at or below your target megabyte limit. Submit large scanned packets to government portals, court filing systems, or email attachments that enforce strict per-file megabyte caps.
This tool splits along page boundaries without recompressing images. If an individual page contains a massive image that exceeds your MB limit by itself, use Compress PDF first.
How PDFolio helps you split PDF by file size
PDFolio incrementally adds pages into a candidate chunk and measures the exact serialized byte size in your browser tab, starting a new chunk whenever adding the next page would exceed your MB threshold.
If you prefer to keep the entire document in a single file, try Compress PDF first to see if lossless or image compression brings it under the limit.
Before you download
Set the size limit slightly below the portal cap (for example, 9.5 MB for a 10 MB limit) to leave room for email encoding overhead.
When the result is ready, download it immediately and open it in your usual PDF viewer to make a final check. You can then use Clear task data to release temporary file references from this browser tab. PDFolio does not create an account, cloud folder, or server-side document history.
A private way to split PDF by file size
PDFolio handles the selected files in the active browser tab. A Web Worker on your device performs the PDF task so the interface can remain responsive; document bytes are not sent to a PDF processing server, upload queue, account database, or advertising platform.
단계
- Add a PDF that exceeds your portal or email size limit.
- Enter the maximum file size in MB (for example, 5 MB or 10 MB).
- Process locally and download each numbered part.
알아 두면 좋은 점: If a single page is already larger than your target MB limit on its own, that page is exported as a single-page part.
자주 묻는 질문
What happens if one page is larger than the maximum MB size?
That single page is saved as its own part so no pages are lost. Run Compress PDF first if individual pages exceed your limit.
Are page order and quality preserved across the parts?
Yes. Every part preserves the exact original pages in sequential order.
Does split PDF by file size change my original file?
No. PDFolio creates a new file for download. Your source file remains unchanged on your device.
