Dear Sir,
Conveyance and Sale Deed essentially have no difference as in both the property documents, the right, interest and title of the previous owner is transferred to the purchaser.
sale deed:
A sale deed acts as the main legal document for evidencing sale and transfer of ownership of property in favour of the buyer, from the seller.
Further, it also acts as the main document for further sale by the buyer as it establishes his proof of ownership of the property.
The sale deed is executed subsequent to the execution of the sale agreement and after compliance of various terms and conditions detailed in the sale agreement as agreed upon between the buyer and the seller.
The sale deed is the main document by which a seller transfers his right on the property to the purchaser, who then acquires absolute ownership of the property.
Conveyance:
Conveyance records the transfer of an interest in immovable property. The conveyance in the immovable property may take place by way of sale deed, gift deed, exchange deed etc.
The Difference:
All deeds transferring the property-rights are conveyance-deeds. Sale-deed is one of them. All sale-deeds are deeds of conveyance but all conveyance-deeds are not sale-deeds
