How to handle it
- Check the attachment type and the email size limit.
- Convert the file to a smaller format that still preserves the important content.
- Open the output before attaching it and keep the original source file.
Before you submit
- Do not convert transparent logos to JPG if transparency matters.
- Listen to converted speech or music before sending important audio.
- For sensitive documents, confirm that email is an appropriate delivery method.
Choose the right output
Use JPG or WebP when a large image does not need transparency.
Use MP3 when a WAV or voice recording is too large for email.
Use MP4 for videos and PDF for documents that need stable layout.

FAQ
What format is safest for email attachments?
JPG, PDF, MP3, and MP4 are usually safer than niche formats because they open on more devices and email clients.
Will converting always make an attachment smaller?
No. It depends on the source and output. PNG to JPG, JPG to WebP, WAV to MP3, and MOV to MP4 often reduce everyday attachment size.
Can I convert several files at once?
Yes. The converter supports up to 10 files in one batch when the files use the same input format.
Do I need to install software?
No. You can start from this page, choose the matching converter, and process files online from the browser.
