If supported by your device, you'll see a Share icon, allowing you to directly send converted files to other apps.
Common questions about converting 3GPP to JXL
Is converting 3GPPs to JXL safe with MConverter?
For cloud-based conversions, MConverter encrypts your 3GPP 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 3GPPs 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.

Can I convert 3GPP to JXL in bulk?
Yes, MConverter supports batch converting of multiple 3GPPs to JXLs simultaneously. You can even drag and drop folders containing 3GPPs to convert to JXL.
Pasting 3GPP files and folders copied in the clipboard also works: use Ctrl+V.

Can I convert a 3GPP file to JXL, if its size is 10 GB?
Yes, with MConverter Max you can convert big 3GPPs, up to 10 gigabytes each.
The free version lets you convert files up to 100 MB. If you need to convert 3GPP 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.

How long does it take to convert 3GPP to JXL?
For most videos, the wait could be a few minutes or less. However, MConverter also supports converting larger videos, meaning that it could take a while (up to over an hour, for example).

Format description
3GP is a multimedia format which can contain both video and audio. Designed by the Third Generation Partnership Project, it is intended for mobile devices with 3G connectivity, though it can also be played on 2G and 4G devices. Note that this format is outdated and superseded by 3G2, which takes up less space and consumes less bandwidth.| File extension | .jxl |

Format description
JPEG XL (or JXL) is a new image format with better compression than other image formats like legacy JPEG, PNG, WebP, AVIF and others. Designed for the modern web and with professional photography in mind, JPEG XL offers a more efficient way of storing images. In addition to supporting alpha channels/transparency, lossless, progressive loading and animations, the new image format promises high speed encoding and decoding even on phones.JPEG XL has experimental support in Firefox, Chrome and other Chromium-based browsers like Edge. For now, you need to enable a feature flag for these browsers to display JXL images. Safari supports only non-animated JPEG XL images since late 2023.
MConverter’s conversions from JPEG XL to other image formats are lossless, so there is no reduction in the quality of your images.
When converting from JPG to JXL, the output quality is mathematically lossless. In all other cases, the JPEG XL image quality is kept visually lossless. Your images will look visually identical.
