Absolutely! Simply note this on the order form and we will assign your new order to the same editor who completed your prior work.

We can edit documents to specific style guides/formats.

Among our 100+ editing professionals, we have format specialists across all the main style guides, including APA, Chicago, Harvard, OSCOLA, Oxford, and others.

If your university or publishing house has provided specific guidelines, we may be able to accommodate these. Please contact us if you have questions.

We are unable to edit LaTeX files directly. However, if you export or copy and paste your LaTeX source code into a Microsoft Word document, we will leave any programming commands unedited. You can then review our changes in Word and copy and paste the text back into the LaTeX source code.

PDF files will be edited by making annotations using Sticky Notes in Adobe. You would then need to manually insert the suggested changes in your publishing software.

Wherever possible, Microsoft Word documents are preferred, as the software enables us to utilize the Track Changes feature to highlight our editing.

PDFtoWord.com is a free online tool that converts PDFs to Word files. Please note: this tool can occasionally cause formatting errors, so please check that your document was converted accurately.

Alternatively, copy-and-pasting the text from your PDF file into Word can be effective.

If you have any questions regarding PDF editing, please contact us.

If you are not satisfied with the service that you have received and can cite fair justification, we will issue a partial or full refund. Please contact us if you have any questions.
