How to delete pages from a PDF
Three steps. Everything runs locally — your file never leaves your device.
Select a PDF
Drop a PDF or pick it from disk. Every page is rendered as a thumbnail in your browser using PDF.js — your file stays local.
Mark the pages to delete
Click any thumbnail to mark it for deletion (a red overlay appears). Or type a range like "1, 3-5, 8" in the text box and click Apply.
Download the trimmed PDF
pdf-lib rebuilds the document without the marked pages and offers it as a download. Bookmarks and internal links are re-targeted automatically; your original file on disk is untouched.
Why use Delete Pages on imisspdf?
Private by architecture
Often the pages you delete are the sensitive ones — bank details, IDs, internal notes. Because nothing uploads, none of that content ever leaves your device. There is no server-side temp file or audit log.
Visual + range syntax
Click thumbnails for short docs, or type "1, 3-5, 8" for long ones. Bookmarks and links are auto-retargeted to surviving pages so your document still navigates correctly.
Free, no watermark
No daily cap, no signup, no logo printed onto your output. Your source file on disk is never modified — only the new trimmed PDF is offered as a download.
Common questions about Delete Pages
Bookmarks and links that point to surviving pages are preserved and automatically re-targeted by pdf-lib — if you delete page 3, a bookmark that pointed to old page 7 still lands on the right content (now page 6). Links that pointed to a deleted page itself become "dangling" — the bookmark stays in the outline but clicking it does nothing, since its destination no longer exists. If your document relies heavily on cross-references (e.g. a contract with appendix links), open it in a reader afterwards and spot-check a few jumps.
Not from the output file — once a page is removed and saved, it is genuinely gone from that PDF. The data is not just hidden, it is excised from the page tree and the resources it referenced are no longer written out. However, your original file is never modified: this tool reads it into memory and writes a new PDF as the download, so the source on your disk is untouched. Keep that original until you confirm the trimmed version is what you wanted. There is no server copy on our side either, because nothing was uploaded.
Use the text box at the top — it accepts standard PDF page-range syntax. Type "1, 3, 5-10" to delete page 1, page 3, and pages 5 through 10 inclusive. You can mix individual pages and ranges, separated by commas. Click "Apply" and the selection is reflected in the grid below; you can still toggle individual pages on or off afterwards. For very long documents (200+ pages), typing the range is much faster than scrolling and clicking, and it avoids accidental mis-clicks.
Be careful here. If the PDF is an interactive form (AcroForm), some fields may be anchored to specific pages — deleting those pages removes the field widgets, but the underlying field definition can remain in the form dictionary as an orphan. Most readers handle this gracefully (the field simply disappears), but a few enterprise workflows (e.g. e-signature platforms) treat orphan fields as validation errors. If your PDF is a fillable form you intend to send for signing, flatten it first with Flatten PDF — that converts fields into static content and avoids the issue entirely.
pdf-lib re-serialises the PDF after removing pages, and by default it does not aggressively discard unreferenced resources like fonts, color profiles, or shared images. So if a deleted page used a font that is also on other pages, that font stays in the file — the page count is smaller but the asset footprint is not. To shrink the file noticeably after deleting pages, run the output through Compress PDF, which removes orphaned objects and recompresses image streams. For purely text PDFs the savings will be roughly proportional to page count.
This tool only produces the "keep" output. If you also want the deleted pages as a separate PDF, use Extract Pages instead — it lets you choose pages and download them as a single PDF or a ZIP of individual files, without touching the originals. A common workflow is: extract sensitive pages to one file (e.g. for archiving), then come back here and delete those same pages from the public-facing copy. Both operations are non-destructive to the source on your disk.
