Split a PDF three ways, all free
Proofmark PDF gives you three ways to split: by custom page ranges (1-3, 5, 8-10), by fixed chunks (every N pages), or by selected pages (click thumbnails to choose). Every page is rendered as a thumbnail locally so you know exactly what you are doing before you hit Split.
Every page is rendered as a thumbnail by PDF.js — locally in your browser — so you can confirm exactly what you are merging or splitting.
Files are processed in memory and returned immediately. Nothing is persisted, archived, or analysed after your response is sent.
Your merged or split PDFs contain only your pages. Proofmark never stamps, brands, or alters your content.

Frequently asked questions
Is Proofmark PDF really free with no limits?
Yes. There is no daily cap, no file count limit, and no signup. The only cap is 100 MB per upload to keep the server responsive.
Are my files uploaded or stored anywhere?
Files are processed in memory and deleted as soon as the response is returned. Nothing is persisted on disk or in any database.
Do I need an account?
No account, no email, no login. Open the page and start merging or splitting.
Does Proofmark PDF add a watermark?
Never. Your merged or split PDFs contain only your original pages. No branding is stamped into the output.
What is the maximum file size?
Each upload is capped at 100 MB. If you need to work with larger files, split them first and merge selectively.
Can I reorder PDFs before merging?
Yes. Drag any row in the merge list to reorder it. Each file shows its first page as a preview so you can confirm the sequence visually.
How do page ranges work when splitting?
Use commas and dashes like 1-3, 5, 8-10. Each comma-separated group becomes its own output PDF, so the example creates three files.
Can I open encrypted or password-protected PDFs?
Not in this build. Remove the password from your PDF first (any reader with owner access can re-save without encryption), then upload.
