مهما ضغطت الملف، لازم اراجع الدقة.

Here مهما introduces a concessive idea: no matter how... or however much...

In this sentence, it means something like:

• No matter how much I compress the file...
• However much I compress the file...

So مهما is setting up the first clause as something that does not change the result in the second clause.

This is very common in Arabic. After words like مهما, Arabic often uses the past form to express a general condition or concession, not only a completed past action.

So مهما ضغطت الملف does not have to mean only no matter how much I compressed the file in a strictly past-time sense. It can also mean:

• no matter how much I compress the file
• however much I may compress the file

This is a normal Arabic pattern and often sounds more natural than using the present tense there.

It can be either in normal Arabic spelling.

The written form ضغطت is ambiguous because short vowels are usually not written. So it could mean:

• I compressed
• you (masculine singular) compressed

In this sentence, the next part is لازم اراجع = I have to review/check, so the most natural interpretation is that ضغطت also means I compressed.

Because Arabic verbs already include the subject.

In this sentence:

• ضغطت can include the meaning I
• اراجع means I review / I check

So Arabic often does not need an explicit subject pronoun like أنا unless the speaker wants emphasis or contrast.

For example:

• لازم اراجع الدقة = I have to check the resolution/accuracy
• أنا لازم اراجع الدقة = I have to check the resolution/accuracy with extra emphasis on I

لازم in Egyptian Arabic is a very common way to say:

• must
• have to
• need to

So:

• لازم اراجع = I have to review/check

A useful thing to remember is that in Egyptian Arabic, لازم is often followed by a present-tense verb:

• لازم أروح = I have to go
• لازم نشتغل = we have to work
• لازم اراجع الدقة = I have to check the resolution/accuracy

Literally, الدقة can mean accuracy, precision, or exactness.

But in a technical context involving a file, it can also refer to things like:

• resolution
• image quality/detail
• precision of output

So the exact English word depends on context. If this is about images, video, or graphics, resolution is very likely. If it is about general technical quality or exactness, accuracy or precision may fit better.

Yes. The basic meaning of ضغط is to press, but it is also used in technical contexts for compressing files or data.

So:

• ضغط الملف = he compressed the file
• ضغطت الملف = I compressed the file

This is a natural extension of the basic idea of pressing/squeezing something into a smaller size.

The definite article الـ means the.

So:

• الملف = the file
• الدقة = the accuracy / the resolution

In this sentence, both nouns are treated as specific and known from context. The speaker is talking about a particular file and the relevant resolution/accuracy of that file.

It is understandable in Egyptian Arabic, but it leans a little toward neutral/semi-formal wording.

Why?

• لازم is very common and clearly Egyptian/colloquial-friendly.
• أراجع and الدقة are perfectly normal words, but they can sound a bit more neutral or formal than very casual everyday speech.

A more casual Egyptian version might be something like:

• مهما ضغطت الملف، لازم أشيّك على الدقة
• مهما ضغطت الملف، لازم أبصّ على الجودة

But the original sentence is still natural and clear, especially in technical or educated speech.

A rough Egyptian pronunciation would be:

mahma ḍaghaṭt il-malaf, lāzem arāgiʿ id-diʔʔa

A few useful notes:

• ج in Egyptian Arabic is usually pronounced like hard g in go
• ق in many Egyptian pronunciations becomes a glottal stop, so دقة sounds roughly like diʔʔa
• The الـ in الدقة assimilates to د, so it is pronounced more like id-diʔʔa, not al-diqqa

So the flow is roughly:

mahma ḍaghaṭt il-malaf, lāzem arāgiʿ id-diʔʔa
