Frequently Asked Questions
Can you fax a JPEG file?
Yes. Most modern online fax services accept JPEG files directly and convert them to fax format automatically. Services like mFax.to support JPG, PNG, TIFF, and other image types with no manual conversion required.
Do I need to convert a JPEG to PDF before faxing?
No — online fax services like mFax.to handle the conversion automatically when you upload your JPEG. Converting to PDF first can help if your image contains fine text or small details you want to preserve.
What image resolution is best for faxing a JPEG?
300 DPI at standard letter size (8.5 × 11 inches) gives the clearest result. Fax transmission compresses images, so starting with a high-resolution JPEG produces a more readable received fax.
Can I fax a JPEG from my phone?
Yes. The mFax app for iOS and Android lets you attach a JPEG from your camera roll or cloud storage, enter the recipient fax number, and send. Delivery typically completes in under 2 minutes.
Does faxing a JPEG reduce image quality?
Traditional fax machines transmit at low resolution (200 DPI or less), which can degrade photo quality. Online fax services like mFax.to preserve significantly more detail by delivering at fine-mode resolution wherever the receiving machine supports it.
