How to Remove Arabic Diacritics and Clean Text Copied From a PDF

You copy a paragraph from an official PDF report and paste it into a Word document, and it looks perfectly fine on screen. Later, you search for a word you know is in that paragraph, and the search does not find it. The problem is not your eyes; text copied out of some PDF files sometimes carries hidden characters between words, or a different kind of space that looks identical visually but breaks literal text-matching in a search.
What does the tool fix?
The Arabic text repair tool on Sahel bundles six independent fixes that can each be switched on separately: removing diacritics, removing tatweel, converting Eastern Arabic digits (١٢٣) to Western digits (123) and back, normalizing the different hamza letter forms into one consistent shape, normalizing alif maqsura and ya, and cleaning the text of hidden characters and broken spacing common in text copied from a PDF. Every option is its own switch, so you apply only what you need without changing the text in ways you did not ask for.
Why does keeping each fix separate matter?
Not every text needs the same treatment. Literary text that needs its diacritics to preserve meaning and correct pronunciation should not have them stripped, while text destined for search or indexing benefits from removing them, since diacritics break word matching in simple search engines. If the tool applied every fix together at once with no choice, it would ruin texts that need some of their original elements intact.
The specific problem with unifying hamza forms
The same word can be written with different hamza forms depending on who wrote it — sometimes from a common typing mistake, not a grammar rule. That means searching for a word with one specific hamza form can miss other copies of the same word written with a slightly different one. Normalizing hamza forms makes text more consistent for search and indexing purposes, without necessarily meaning the original form was a spelling error.
Steps to use it
- Paste the text that needs processing into the input box.
- Turn on only the fixes you need from the list — each switch is independent of the others.
- Check the result in the output box to confirm it matches what you want.
- Copy the clean text and use it in its final destination.
Eastern or Western Arabic digits: which do you need?
Eastern Arabic digits (١٢٣) are common in certain documents and sites, while the internationally standard Western digits (123) are what most digital forms and software systems expect. Text containing Eastern digits pasted into a numeric field in a system that does not recognize them can get the entry rejected outright or misread entirely, so converting the format before entering it avoids the problem at its root.
A real case
A researcher gathers quotes from several books and studies in PDF form for an academic paper, copying paragraphs from different sources that each carry varying degrees of diacritics and inconsistent hamza forms. Before assembling the quotes into one final document, she runs each paragraph through the tool to unify the hamza forms and strip any hidden characters that stuck to the text during copying, so the final document comes out visually consistent despite its varied original sources.
In another case, a clerk receives data from an older system that exports numbers in Eastern Arabic digits, and needs to enter it into a modern accounting system that only accepts Western digits. He uses the tool to convert all the numbers at once instead of manually editing every single figure in every field.
Frequently asked
Are diacritics removed automatically from every text?
No, each fix is an independent switch you turn on yourself; diacritics are removed only if you enable that option, and it is never applied automatically to text you paste.
Does cleaning the text change its meaning?
No, the available fixes address the texts visual and symbolic form — diacritics, tatweel, digits, letter forms — without changing the words themselves, their order, or their meaning.
What is the point of removing tatweel specifically?
Tatweel is a purely visual formatting mark used to stretch a letter without adding meaning, and some text copied from certain sources carries a lot of it, so removing it cleans up the text and reduces its size without affecting meaning.
Is the text I paste into the tool saved anywhere?
No, processing happens entirely inside your browser with nothing uploaded to an external server.
Can the tool clean a very long piece of text all at once?
Yes, relatively long text can be pasted and processed in one pass, which is especially useful when assembling text from multiple sources that all need consistent normalization before final use.
