How it works
Add a PDF and click the pages you want to remove. They are crossed out so you can see what will be left. For long documents, type page numbers or ranges such as 2, 5-8 and mark them all at once.
Press Delete and Vimorby builds a new PDF from the remaining pages, in their original order. At least one page has to stay.
A smaller file
The new PDF only contains what the remaining pages use, so deleting image-heavy pages makes the file smaller. Bookmarks and form fields from the original may not be kept.
Pages are copied exactly as they are, using the open-source pdf-lib library in a background worker: text stays selectable, and nothing is re-compressed or watermarked.
Your files are processed by your own browser, inside this tab. Nothing is uploaded, so there is no server copy to delete, and the page keeps working if you go offline after it loads.
