To avoid the inconveniences of organic solvents (safety and availability), some brands of fluid are water-based. Therefore, some manufacturers also sell bottles of solvent as "thinner", a few drops of which will return the correction fluid to its original liquid state. It can become too thick to use, and sometimes completely solidifies.
Because it contains organic solvents ( volatile organic compounds), unused correction fluid thickens over time as volatile solvents escape into the air. Thinners currently used with correction fluid include bromopropane.

Later, it contained 1,1,1-trichloroethane, a skin irritant now widely banned under the Montreal Protocol on Substances That Deplete the Ozone Layer, and then the slightly safer trichloroethylene. Thinner originally contained toluene, which was banned due to its toxicity. The opacifying agent can be composed of a mixture of titanium dioxide, latex, and other polymer resins. The exact composition of correction fluid varies between manufacturers, but most fluids are composed of an opacifying agent, a solvent (or thinner) and an adulterant 'fragrance' to discourage abuse. Correction fluid was applied on a glass base (visible in the bottom-right corner of all SEM images). The micro-structural details of the copolymer resin are visible under high magnifications.

Other tools are also available on Smallpdf, in case the output file needs to be in PPT, Excel, or JPG (albeit the last option does not leave a lot of room for editing).Ĭonversely, if you have a document on hand that isn’t in PDF format, the all-in-one PDF converter can first save your file to PDF format, so that you can freely white out your PDF using our editor, following the instructions illustrated above.Correction fluid copolymer visualized under scanning electron microscopy (SEM).

If you upload scans, Optical Character Recognition (OCR) is available for Pro users, which recognizes and extracts all types of content and places them accordingly onto the output file. With this, you can freely remove, edit, or enhance existing text on your digital file, as per your needs. Can I Modify the Existing Text in a PDF?Įven though the option to select the text within a PDF isn’t available, especially for scanned PDFs, you can always use the PDF to Word tool to convert your document into an editable file.

And lastly, an offline Desktop editor is also available for our Pro users if you’re looking for an Adobe Acrobat alternative. Better yet, as an online platform, you can conduct the PDF white out by clicking on the tool from our homepage, from anywhere with a stable internet connection. As such, our edit tool can be accessed from any device, for occasional free use. We believe that the options to convert and edit PDF files should be available to anyone to use. Other than the redaction tool in white and the option to add text, you can also insert drawings and images to your PDF file. With the same edit tool you can select the text icon from the toolbar and instantly place new text directly on top of the white-out box. Of course! But it’s much easier than what you might remember from grade school-waiting for the liquid white-out to dry so you can painfully try to write over it. Can I Edit Text on Top of the Whitened Out Content? Thus, make sure you have a copy of the original document elsewhere before you apply the redaction to the text-unless the information is to be forever hidden. Whiting out text will ensure that nobody can view or edit the content that has been covered.
