What Is PDF Page Deletion?
Deleting pages from a PDF means producing a new document without selected pages. Common uses: cleaning blank scans, stripping ads from ebooks, hiding confidential exhibits before sending a contract, or simply trimming file size. Convertilo deletes pages locally via pdf-lib — kept pages are copied without re-rendering, fonts and bookmarks survive, and the result is re-saved with object streams to keep it compact.
About Deleting PDF Pages
Remove unwanted pages from a PDF — ad inserts, duplicates, blank scans or confidential exhibits. Pick pages by clicking on thumbnails or enter ranges like "1, 3-5, 8" — the remaining pages are assembled into a new PDF without any quality loss or re-rendering.
How Page Deletion Works
- Source PDF is parsed with pdf-lib, structure unpacked
- Only kept pages are copied via copyPages — bookmarks, fonts and signatures are preserved
- PDF.js renders thumbnails so you can pick pages visually
- Range parser supports "1-5, 7, 10" syntax just like a printer dialog
- Everything runs locally — your file never leaves your browser
Technology Behind Our PDF Tools
Our PDF tools are built on two powerful JavaScript libraries that run entirely in your browser:
pdf-lib — A library for creating and modifying PDF documents. Used for merging, splitting, and page manipulation operations.
PDF.js — Mozilla's PDF rendering engine for parsing and displaying PDF content. Powers our PDF viewer and page export features.
Canvas API — Browser's built-in rendering API used for converting PDF pages to image formats (JPG, PNG, WebP) at any resolution.
All operations are performed locally — your documents are never uploaded to any server, ensuring complete confidentiality.
Benefits of Deleting PDF Pages
Visual selection
Click on page thumbnails — selected ones get highlighted in red and queued for removal.
Printer-style ranges
Type "1, 3-5, 8" — we understand ranges and commas, so you don't have to tick every page individually.
No quality loss
Remaining pages are copied without re-rendering — bookmarks, fonts and signatures are kept intact.
Delete PDF Pages FAQ
How do I select pages to remove?
Two ways: click on a page thumbnail (it'll get highlighted in red), or type a range into the "Pages to delete" field — for example, "1, 3-5, 8". Both can be used together.
How do ranges work?
Single page numbers and dash-ranges separated by commas: "2, 5-7, 10" deletes pages 2, 5, 6, 7 and 10. Out-of-bounds numbers are ignored.
Will the remaining pages keep their quality?
Yes. The remaining pages are copied as-is — no re-rendering, no recompression, no font loss. Bookmarks, signatures and stamps stay in place.
Will the file size go down?
Usually yes, roughly proportional to how many pages were removed. After deletion the document is also re-saved with object streams — the resulting file is never larger than the source.
Where is my document processed?
Entirely in your browser via pdf-lib. The file never goes to our servers — confidential pages stay confidential.
