Batch convert from PPT to other formats.
Large PPT files are supported.

If you don't know how to view a PPT file, you can convert it to another format you already recognize. You can use MConverter for the conversion.

Yes, MConverter supports batch converting of multiple PPT files at once. You can even drag and drop folders containing PPTs.
Pasting PPT files and folders copied in the clipboard also works: use Ctrl+V.

Yes, with MConverter Max you can convert big PPTs, up to 10 gigabytes each.
The free version lets you convert files up to 100 MB. If you need to convert PPT files over 100 megabytes, try MConverter Max. If your files aren’t over 1 GB, then you can use MConverter Plus instead, as it’s cheaper.

For cloud-based conversions, MConverter encrypts your PPT files using the latest technologies, such as TLS 1.3 and HSTS. They are transmitted securely to our cloud service provider’s EU-based data center, which holds internationally recognized ISO 27001 and SOC 2 certifications. There, each conversion is processed in a separate, isolated environment. This technique further reduces the risk of a malicious file impacting other conversions.
Four hours after the conversion is complete, your files are automatically deleted from MConverter’s systems. You can also permanently delete your PPTs and other converted files immediately after finishing the conversion with the trash icon.
When converting on-device, your files never leave your device. MConverter processes them locally. Note: on-device conversions are not yet available for some hardware-intensive formats.
For both cloud and on-device conversions, your files are never scanned or shared with third parties for marketing purposes.

For most documents, the wait may be a minute or so. However, MConverter also supports converting larger documents, meaning that it could take a while (up to over an hour, for example).
