A page that is larger on its own goes into a file of its own, and the Toolbox names it.<\/li>\n\n\n<li><strong>Add page numbers:<\/strong> With \"Digits\" the numbers get leading zeros, for example 000001. \"Number continuously across all files\" numbers several files in one sequence, in the order of the file list.<\/li>\n\n\n<li><strong>Images to PDF:<\/strong> Very long images such as scrolling screenshots are spread over several pages of the chosen page size instead of one overlong page that can hardly be printed. If you don't want that, uncheck \"Split long images over several pages\".<\/li>\n\n\n<li><strong>Flatten PDF:<\/strong> Form fields, comments, drawings, stamps and free text are burned in as they are shown on the screen, as with PDF24 online. Links are kept.<\/li>\n\n\n<li><strong>Unlock PDF:<\/strong> Certified PDFs, for example from Adobe Acrobat, stayed locked against changes in Acrobat after unlocking. The new option \"Remove certification\" lifts this.<\/li>\n\n\n<li><strong>Make PDF fillable:<\/strong> Form fields can be rotated by 90, 180 or 270 degrees, for example as a label in the page margin.<\/li>\n\n\n<li><strong>Convert from PDF:<\/strong> PDF to Markdown has the option \"Embed images\"; without it you get only the text, and the file stays small. PDF to PDF\/A has the check box \"Remove document information\".<\/li>\n\n<\/ul>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"1086\" height=\"592\" src=\"https:\/\/help.pdf24.org\/en\/wp-content\/uploads\/sites\/3\/2026\/11\/11.34.0-5-split-pdf-en.png\" alt=\"PDF24 Toolbox, tool &quot;Split PDF&quot; with the mode &quot;By file size&quot; and the field &quot;Maximum size&quot; in MB\" class=\"wp-image-67057\" srcset=\"https:\/\/help.pdf24.org\/en\/wp-content\/uploads\/sites\/3\/2026\/11\/11.34.0-5-split-pdf-en.png 1086w, https:\/\/help.pdf24.org\/en\/wp-content\/uploads\/sites\/3\/2026\/11\/11.34.0-5-split-pdf-en-300x164.png 300w, https:\/\/help.pdf24.org\/en\/wp-content\/uploads\/sites\/3\/2026\/11\/11.34.0-5-split-pdf-en-1024x558.png 1024w, https:\/\/help.pdf24.org\/en\/wp-content\/uploads\/sites\/3\/2026\/11\/11.34.0-5-split-pdf-en-768x419.png 768w\" sizes=\"auto, (max-width: 1086px) 100vw, 1086px\" \/><figcaption class=\"wp-element-caption\">Split PDF by file size: no file gets larger than the size you enter.<\/figcaption><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">On the start page of the Toolbox, the sections favorites, recently used and categories can now be collapsed with a click on the heading.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Many tools of the PDF24 Toolbox have new options in version 11.34.0: On the start page of the Toolbox, the sections favorites, recently used and categories can now be collapsed with a click on the heading.<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[2],"tags":[],"class_list":["post-67058","post","type-post","status-publish","format-standard","hentry","category-creator"],"_links":{"self":[{"href":"https:\/\/help.pdf24.org\/en\/wp-json\/wp\/v2\/posts\/67058","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/help.pdf24.org\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/help.pdf24.org\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/help.pdf24.org\/en\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/help.pdf24.org\/en\/wp-json\/wp\/v2\/comments?post=67058"}],"version-history":[{"count":0,"href":"https:\/\/help.pdf24.org\/en\/wp-json\/wp\/v2\/posts\/67058\/revisions"}],"wp:attachment":[{"href":"https:\/\/help.pdf24.org\/en\/wp-json\/wp\/v2\/media?parent=67058"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/help.pdf24.org\/en\/wp-json\/wp\/v2\/categories?post=67058"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/help.pdf24.org\/en\/wp-json\/wp\/v2\/tags?post=67058"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
