How to Delete Pages from a PDF Online for Free

Open the iFormat PDF Page Remover in any browser. Upload your PDF and you will see a thumbnail grid showing every page in the document. Click any page to mark it for deletion — it gets a red overlay so you can clearly see which pages you are about to remove. Click a marked page again to unmark it if you change your mind. You can also select a range of pages if you need to remove a continuous section — say, pages 15 through 25.

When you are happy with your selection, click Download and get the cleaned-up PDF. The tool creates a new file that contains only the pages you kept. Your original file is never modified — it stays exactly as it was, so you always have it as a backup in case you accidentally deleted a page you needed.

This is the single most common reason people need to delete PDF pages, and it is caused by duplex scanners — scanners that capture both sides of every sheet. When you feed single-sided paper through a duplex scanner, it faithfully scans the blank back of each page and saves it as an empty white page in the PDF. A 10-page single-sided document becomes a 20-page PDF with every other page blank. It doubles the file size for no reason and makes scrolling through the document annoying.

The fix is simple: upload the scanned PDF to the page remover, scan the thumbnail grid for the blank pages (they are obvious — just white rectangles with no content), click each blank page, and download the cleaned version. A 20-page document with 10 blank pages goes down to 10 pages in about 15 seconds of clicking.

For future scans, check your scanner's settings for a "skip blank pages" option. It is usually under Advanced, Image Processing, or Scan Settings depending on the scanner brand. Canon, HP, Epson, and Brother all have this feature on most of their ADF scanners. But for documents you have already scanned without that setting, the online page remover is the fastest fix.

Government forms, university documents, corporate templates, and official paperwork almost always come with a cover page and several pages of instructions stapled to the front of the actual form. For filing, uploading, or sending to someone else, you usually only need the form itself — the instructions are just dead weight.

Upload the full document, select the instruction pages at the beginning, and download the trimmed version containing only the form. If you then need to fill in the form fields digitally, the form fields on the remaining pages are completely unaffected by the deletion — they work exactly as they did in the original document.

Every page in a PDF contributes to the overall file size. Text-only pages are lightweight — a page of typed text might add 5-20 KB to the file. But scanned pages, pages with photographs, charts with embedded images, or pages with detailed graphics can each add 200 KB to 1 MB or more. Removing just three image-heavy pages from a 20-page scanned document can cut the file size by 30-40%.

This makes page deletion a powerful first step before compression. If you need to get a PDF under a size limit for an upload portal, removing unnecessary pages first means the compressor has less work to do and can use a higher quality setting for the pages that remain. Delete first, compress second — that is the order that produces the best quality at the smallest size.

Preview on Mac can delete PDF pages natively without any additional tools. Open the PDF in Preview, go to View > Thumbnails to show the page sidebar, select the pages you want to remove (Cmd-click to select multiple non-consecutive pages, Shift-click for a range), and press the Delete key. Then save with File > Export as PDF to create the final version.

This works well for quick one-off edits, but Preview has a documented quirk: the exported PDF sometimes re-renders fonts using macOS's own font pipeline rather than copying the original font data. The result can look different — or have missing characters — when opened on Windows or Linux. For documents that will stay on your Mac, Preview is fine. For anything you are sending to someone else, especially for official submissions, a dedicated tool that preserves the original font embedding is more reliable.

Windows has no built-in PDF page deletion feature. Microsoft Edge can print selected pages to a new PDF (Ctrl+P > Save as PDF > set a custom page range), but this re-renders every page as a new image rather than copying the original page objects, so you lose form fields, selectable text quality, and annotations. For a non-destructive deletion that preserves everything on the remaining pages, the online tool works in any Windows browser — Chrome, Edge, Firefox — and produces a clean result without any software installation.

Deleting pages is often one step in a longer document cleanup workflow. Here is what usually comes next:

• Merge the trimmed PDF with other documents if you are assembling a multi-part submission or report.
• Rotate any remaining pages that came through the scanner at the wrong orientation.
• Compress the PDF under 1 MB if an upload portal or email system has a file size limit.
• Add your signature if the document needs to be signed before submission.

Each of these operations works independently, so you can chain them in whatever order makes sense for your specific situation. The general rule: delete unnecessary pages first (it reduces file size and simplifies everything else), then rotate, merge, sign, and compress as needed.

Can I undo a page deletion?
The tool creates a new file and never modifies your original. If you deleted the wrong page, just re-upload the original PDF and try again. Your original document is always intact.

Does deleting pages break the table of contents?
If the PDF has an internal table of contents with links (bookmarks), any bookmarks pointing to deleted pages become orphaned — they still appear in the bookmark list but clicking them does nothing. Bookmarks pointing to remaining pages continue working, though the page numbers they reference will shift to account for the removed pages.

Can I delete pages from a PDF that has form fields?
Yes. Form fields on the remaining pages are fully preserved and continue to function. Fields that existed on deleted pages are removed along with the page — they disappear cleanly without affecting anything else in the document.

Is there a file size or page count limit?
Free tier: files up to 50 MB, unlimited page count. Pro: files up to 200 MB. The tool handles both tiny 2-page documents and 500-page reports.

Can I delete pages from a scanned PDF?
Absolutely. Scanned PDFs are the most common use case for this tool. Each scanned page is an image wrapped in a PDF container, and it deletes the same way as a text-based page — the tool simply excludes that page object from the new file.

Will deleting pages affect the remaining pages in any way?
No. The remaining pages are copied unchanged into the new file. Their content, formatting, fonts, images, form fields, and annotations are identical to the originals. The only change is that page numbers shift — if you delete pages 3 and 4, what was page 5 becomes page 3 in the new file. Any internal hyperlinks or bookmarks are recalculated to point to the correct pages in the new numbering.
